Vitamins D and E are fat-soluble vitamins essential for overall health and vitality. While vitamin D strengthens your bones and muscles, vitamin E works to support skin and cell health. Both play special roles in keeping your immune system healthy. Here’s why taking vitamin D, however, is better for directly boosting your energy and immunity, according to experts.

If your goal is immune support, vitamin D matters more, Kevin Gendreau, MD, an obesity and family medicine physician in Massachusetts, told Health. Vitamin D actively regulates immune responses, and when levels are too low, your risk of infection increases.

Research shows that vitamin D helps your immune cells fight bacterial and viral infections, and potentially reduces your risk of autoimmune disease. It also guides your body to absorb calcium, thereby strengthening bone marrow—where immune cells are made and stored.

Your healthcare provider may suggest vitamin D supplements if you have an autoimmune condition or a compromised immune system, which can make you more prone to catching colds, the flu, or other viral illnesses. It won’t completely protect you from getting sick, but it will help your health overall.

Vitamin E, a powerful antioxidant, only indirectly supports the immune system by reducing oxidative stress (the buildup of toxins) in the body, said Gendreau. In fact, very few human studies have found that vitamin E has a noticeable and direct impact on immunity.

For most people, “vitamin E is not as vital to immune signaling as vitamin D,” Gendreau adds. Adding vitamin D-rich foods to your diet, along with immune-supporting nutrients like zinc and vitamin C, can help strengthen your immunity.

Neither vitamin directly provides energy, “but vitamin D deficiency can lead to fatigue,” Kristen Carli, MS, RD, a registered dietitian with WOWMD, told Health. Correcting the deficiency, however, “almost always improves energy levels and mood,” said Gendreau.

About 1 billion people worldwide are vitamin D-deficient. Because it’s so common, you might not even realize you’re deficient, and that low levels are behind your tiredness. Gendreau says other common signs of deficiency include muscle weakness, low motivation, and low energy.

Unless you have a severe vitamin E deficiency (which is uncommon), taking vitamin E supplements will not reliably boost your energy. Fatigue is rarely a sign of low vitamin E. Instead, you might have ataxia (poor muscle coordination), muscle weakness, or arrhythmia (irregular heartbeat), though these can take years to show up.

You won’t get an immediate energy boost after taking one vitamin—nutrients take time to build up in your bloodstream. Studies show taking vitamin D every week, for example, could take up to two months to relieve fatigue.

People with little sun exposure, risk of osteoporosis (a condition that weakens bones), autoimmune disease, or low vitamin D levels would benefit from vitamin D supplements, said Gendreau.

The recommended daily intake of vitamin D is 600 to 800 International Units (IU) per day for most adults, said Carli, but your healthcare provider might prescribe more if you’re severely deficient.

Most people do not need vitamin E supplements—you can get the daily recommended 15 milligrams through foods like nuts, seeds, spinach, and avocado. “Only supplement if you have a true deficiency tested by a physician or malabsorption issues,” said Gendreau.

Your vitamin E levels might be low if you have:

• Gastrointestinal conditions like Crohn’s disease
• Liver disease
• Exocrine pancreatic insufficiency
• Cystic fibrosis
• Malabsorption issues (difficulty absorbing certain nutrients) due to illness or old age

If you’re having trouble meeting the suggested 600 to 800 IU of vitamin D, there are a few things you can do:

• Get outside for five to 30 minutes per day: Even if it’s cloudy, you may still reap benefits.
• Eat fatty fish: For example, trout, salmon, mackerel, egg yolks, fortified dairy, and mushrooms.
• Take a supplement: Most contain 400 to 10,000 IU, but depending on your deficiency (determined through bloodwork), you may need up to 50,000 IU once per week for six to eight weeks.

You may need to use caution or avoid vitamin D and E supplements in certain instances, according to Gendreau and Carli. This includes people:

• With high calcium levels
• Taking medications that increase calcium, such as thiazide diuretics
• With kidney conditions
• With bleeding disorders
• Taking blood-thinning medications like Warfarin
• With upcoming surgeries

Consult your healthcare provider before trying any new supplement, especially if the above apply to you.

Green tea and coffee are two popular beverages that can increase alertness and are associated with a range of health benefits, including supporting heart health. However, the best one for boosting energy and protecting your cardiovascular system depends on your goals and individual needs.

Whether you get better energy from green tea or coffee depends on your goals. While caffeine content varies, coffee generally has more per serving—about 80 to 100 milligrams (mg) per 8 ounces compared with 25 to 50 mg in the same amount of green tea. “The higher concentration of caffeine in coffee gives people a quicker and bigger boost of energy,” said Natasha Bhuyan, MD, a family physician and national medical director at One Medical.

Green tea, on the other hand, may not provide an immediate jolt, but it contains compounds that support more sustained alertness. “Green tea contains L-theanine, which is an amino acid that can promote calm alertness and reduce jitteriness,” Alison Swiggard, MS, RDN, LD, a registered dietitian with CV Wellbeing, told Health.

Both coffee and green tea may support heart health, said Michelle Routhenstein, MS, RD, CDCES, CDN, a preventive cardiology dietitian at Entirely Nourished. This is likely due to green tea’s catechins and coffee’s chlorogenic acids.

“Green tea may offer a slight benefit for LDL oxidation and blood vessel function, while coffee is consistently associated with lower all-cause and cardiovascular mortality,” she said. According to Routhenstein, population studies have linked both beverages to reduced risks of heart disease and stroke.

However, acute blood pressure spikes are more pronounced with coffee, Routhenstein said, so those with high blood pressure or arrhythmias may benefit from green tea or decaffeinated options.

Certain factors can influence how each beverage affects your body.

When it comes to energy, “individual tolerance, sleep quality, intake of food, and anxiety levels matter more than the beverage itself,” Swiggered explained. Another factor is how quickly you metabolize caffeine, Routhenstein said. “Fast metabolizers may experience a milder, shorter stimulant effect from coffee, while slow metabolizers may feel jittery or notice longer-lasting effects.”

For heart health, preparation matters. If you add sugar or cream to coffee but drink green tea plain, green tea may be the healthier option, Routhenstein noted.

It’s also important to consider digestive sensitivity. For people with IBS or sensitive digestion, coffee may worsen symptoms, Swiggard said. Because caffeine can act as a mild diuretic and bladder irritant, it may increase urinary urgency and frequency in those who are sensitive or have conditions like pelvic floor dysfunction. “Because green tea has less caffeine, it’s often gentler on the bladder,” she added.

Ultimately, the ideal beverage depends on your individual physiology. “The ‘better’ choice is the one you feel best drinking without unwanted side effects,” Swiggard said.

Detox supplements abound, claiming to boost energy and metabolism, help with weight loss, cleanse your colon, reduce gas and bloating and–of course–remove toxins from your body. It’s easy to see the appeal, especially when you’re in need of a reset or looking for more energy. But despite the detox supplement boom, the science behind these claims is thin. 

Plus, your body doesn’t need a detox, says Heather Gosnell, M.D. 

“The liver and kidneys are already incredibly efficient, self-regulating organs designed to filter and eliminate waste continuously,” adds Gosnell. Not only are these organs built for detoxing, some supplements can actually harm them. “The most dangerous ‘detox’ supplements are the ones that damage the very organs they claim to help,” says Gosnell.

Here’s what experts want you to know about the dangerous side effects of using supplements to detox, plus proven strategies to help you feel your very best.

Dangerous Side Effects of Using Supplements to “Detox”

They May Impair Nutrient Absorption

Many detox supplements contain polyphenols such as resveratrol or EGCG from green tea extract. In proper amounts, polyphenols act as antioxidants, protecting our cells from damaging oxidative stress that can contribute to chronic diseases.

While the amounts of polyphenols naturally found in whole foods can be beneficial, the excessive doses in some supplements can work against you. For instance, abnormally large amounts of polyphenols may inhibit iron absorption, increasing the risk of iron deficiency. That can lead to fatigue, headaches, dizziness and trouble concentrating.

They May Cause Liver Damage

“Research shows that many seemingly natural supplements can cause liver inflammation, elevate liver enzymes or in rare cases, cause liver failure,” explains Kiran Campbell, RDN.

Green tea extract, often used in detox supplements that claim to boost energy or speed weight loss, makes an appearance here, too. Evidence suggests that high doses of a compound in green tea, called epigallocatechin gallate (EGCG), can injure the liver. It is unclear exactly how this happens. However, experts suspect too much EGCG may increase levels of harmful molecules in the liver or interact with a liver enzyme, called cytochrome P450 (CYP450), which is needed to break down drugs, toxins and alcohol to detoxify the body naturally.

Colon-cleanse supplements may also include several herbs that can also lead to liver damage, when used in excessive amounts, especially if they include ashwagandha, senna or cascara sagrada. However, liver damage isn’t the only reason to avoid some of these herbs. “The misuse of harsh stimulant laxatives like senna or cascara sagrada in high-dose cleanses causes severe diarrhea, leading to dangerous fluid loss and electrolyte imbalances,” Gosnell explains.,

They May Have Dangerous Drug Interactions

“Another danger of detox supplements is drug interactions,” explains Gosnell. “Many herbs interfere with drug metabolism, which can lead to either toxic levels in the blood or render prescribed medications ineffective.” 

One major offender is grapefruit extract, which may be found in detox supplements claiming to increase fat burning or promote gut health. Grapefruit is notorious for interfering with CYP450 enzymes, potentially altering the effectiveness of a long list of medications, especially cholesterol-lowering drugs. Ditto for licorice extract, another common addition to detox supplements.

Green tea extract makes the list as well. It has been shown to interfere with the effectiveness of medications used to treat high blood pressure, cholesterol and osteoporosis. If you’re wondering why green tea extract seems to cause so many adverse effects, it can be helpful to know that it has been studied in far more detail than many other supplements. So, it’s hardly the only troublemaker. There’s just more research behind it.  

They May Be Contaminated with Toxins

Supplements are not regulated by the Food and Drug Administration the same way that medications are. As a result, there is less oversight to ensure they are free of contaminants or that they even contain the ingredients they claim to.  

To complicate matters, supplements often contain heavy metals, undisclosed or synthetic ingredients, and even unapproved drugs that are known to be liver toxins, says Gosnell. “In fact, high concentrations of some supplement components can overwhelm the liver’s metabolic pathways, leading to inflammation, elevated liver enzymes and even liver failure requiring a transplant or resulting in death,” she notes.

Healthy Strategies to Help Your Body Feel Its Best

“What people usually mean when they say they want a ‘detox’ is that they want to feel lighter, less sluggish or more energized,” says Juliana Crimi, RD, M.H.Sc. Instead of supplements, focus on these simple habits that actually support your body’s natural detox systems.

• Stay well-hydrated: “Water supports kidney function, helps move waste through the body and prevents constipation,” says Campbell.
• Get enough sleep: Campbell encourages sleeping seven to nine hours to activate the brain’s waste removal or “detox” system.
• Focus on fiber: “Fiber helps remove waste products, supports the gut microbiome and promotes regularity,” explains Campbell. Aim for 25 to 34 grams of fiber daily from a combination of whole grains, nuts, seeds, legumes, fruits and vegetables.
• Limit added sugars: Added sugars can spell all kinds of trouble for your health, including promoting liver disease. That doesn’t mean you can never enjoy the occasional sweet, but a good goal is no more than 10% of your daily calories.
• If you smoke, seek help quitting: We don’t have to tell you that smoking is bad for you. But did you know that in as little as 14 days without cigarettes, the body rids itself of harmful compounds and undergoes a significant reduction in inflammation? That’s a detox in itself!

Our Expert Take

Detox supplements may be trendy. But they’re not backed by strong science, and in many cases, they can do more harm than good. The truth is, your body already has its own sophisticated detox system: Your liver and kidneys. Instead of focusing on supplements, prioritize the basics: good sleep, proper hydration and a balanced, high-fiber eating plan. As Crimini puts it, “If you want a reset, start with your plate and your pillow, not a pill.”

Mitochondrial is one of the most talked-about metabolic supplements right now, especially among people who struggle with low energy, stubborn fat, and slow metabolism despite diet and exercise. Marketed as a science-backed mitochondrial support formula, Mitochondrial claims to help the body produce energy more efficiently, burn fat at the cellular level, and improve overall metabolic health without stimulants or extreme dieting. In this in-depth Mitochondrial review, we take a realistic look at how it works, what’s inside, real benefits, possible downsides, and whether it’s actually worth your money. This article is written to help you make an informed decision – not to sell you false promises.

What Is Mitochondrial and How Is It Supposed to Work?

Mitochondrial is a di*tary supplement designed to support mitochondrial function, which plays a key role in how your body converts nutrients into usable energy. Instead of focusing on appetite suppression or stimulants, Mitochondrial targets the root cause of low energy and slow fat burning by improving cellular efficiency. According to the official website, the formula aims to activate dormant metabolic processes that naturally decline with age, stress, and poor lifestyle habits. This approach appeals especially to people over 30 who feel tired, sluggish, or stuck at the same weight despite trying multiple diets or supplements in the past.

Mitochondrial Ingredients: What’s Inside the Formula?

Mitochondrial uses a blend of plant-based antioxidants and adaptogens such as Maqui Berry, Rhodiola Rosea, Amla Fruit, Schisandra, Haematococcus (astaxanthin source), and Cocoa Extract. These ingredients are known for their antioxidant properties and potential role in reducing oxidative stress – a key factor linked to mitochondrial decline. While individual ingredients have scientific support for cellular health and energy metabolism, it’s important to be honest: there are no large independent clinical trials proving Mitochondrial as a finished product causes direct fat loss. That said, the ingredient profile is clean, stimulant-free, and generally well tolerated.

Real User Experiences: What Do Customers Report?

User feedback for Mitochondrial is mixed but generally positive. Many users report improved daily energy levels, better mental focus, and less afternoon fatigue after consistent use for several weeks. Some also mention gradual fat loss, particularly around stubborn areas like the abdomen. However, results are not instant. Most positive experiences appear after 3-6 weeks of continuous use, especially when combined with basic lifestyle improvements like walking or balanced meals. Users expecting dramatic weight loss without any effort may be disappointed, which is important to state clearly.

Potential Downsides and Honest Criticism

Mitochondrial is not without drawbacks. First, the price is higher than standard supplements, which may not suit every budget. Second, while the formula is natural, results vary depending on age, metabolism, and lifestyle, so it’s not a guaranteed solution for everyone. Lastly, because Mitochondrial is popular, there are reports of fake copies sold outside the official website, which can pose safety risks. For this reason, ordering only through the official source is strongly recommended.

Is Mitochondrial Safe?

Based on the disclosed ingredients, Mitochondrial appears safe for most healthy adults when used as directed. It contains no stimulants, no synthetic fat burners, and no habit-forming substances. Still, anyone with medical conditions, pregnancy, or medication use should consult a healthcare professional before starting any supplement. Mitochondrial also comes with a 90-day money-back guarantee, which reduces financial risk for first-time users.

Final Verdict: Is Mitochondrial Worth Trying?

Mitochondrial is not a miracle weight-loss pill, but it can be a solid option for people who want to support their metabolism and energy levels in a more natural, sustainable way. Its focus on mitochondrial health makes it different from typical fat burners, and the ingredient profile is well thought out. If you’re realistic about expectations and consistent with usage, Mitochondrial may help you feel more energized and support gradual fat loss over time.

The dietary supplement industry is at a pivotal moment. As people place greater emphasis on proactive health, prevention, and daily wellness, dietary supplements have become an essential part of how individuals support their bodies and overall quality of life. Behind every trusted supplement is one critical foundation: responsible, high-quality manufacturing. 

Consumers today are more health-conscious than ever. Rather than waiting for illness, people are seeking ways to support energy, recovery, immune function, longevity, and overall well-being through informed nutrition and supplementation. This shift has driven rapid growth across the dietary supplement sector, spanning both human and pet health. 

As demand increases, so does the need for supplements that are safe, effective, and thoughtfully formulated. Manufacturing plays a defining role in ensuring products truly support health rather than simply meeting market trends. 

The growth of the dietary supplement industry presents significant opportunities within manufacturing — particularly in innovation. Modern supplement manufacturing is where science, technology, and quality systems converge to turn health-focused ideas into reliable products. 

Innovation in manufacturing enables: 

· Science-informed, accurately dosed supplements consumers can trust 

· Improved manufacturing technologies that enhance consistency, safety, and scalability 

· Formulation advancements that support bioavailability and functional delivery 

· Adaptation to evolving regulatory and quality expectations 

· Infrastructure that supports responsible growth and global distribution 

When innovation is integrated into manufacturing, it strengthens the entire supplement industry and protects the people who rely on these products for their health. 

Montana Global Health, based in Kalispell, is a contract manufacturer of dietary supplements for both human and pet health. We work with clients across the United States and around the world, manufacturing products that are shipped globally while maintaining consistent standards for quality, documentation, and compliance. 

Our role is to support brands committed to proactive wellness, transparency, and integrity. From ingredient sourcing and formulation support to scale-up and final production, every decision impacts consumer trust and long-term outcomes. 

As individuals continue to prioritize their health, dietary supplements will remain an important tool in preventive and supportive care. The future of the industry will be shaped by manufacturers who embrace innovation, accountability, and higher standards. 

Manufacturing opportunities in dietary supplements extend beyond growth alone. They represent a chance to improve health outcomes, support informed consumer choices, and build an industry grounded in quality and integrity.

Investors hunting for fireworks in Japanese consumer stocks will not find a spectacle in Ito En right now, but the market’s message is quietly constructive. The tea and beverage specialist has edged up over the past several sessions, extending a steady medium term advance while avoiding the sharp swings seen elsewhere in the food and drink space. The tone around the stock is neither euphoric nor fearful. Instead, Ito En sits in that intriguing middle ground where resilient fundamentals and modest valuation upside coexist with very real margin and FX risks.

One-Year Investment Performance

A year ago, buying Ito En looked like a conservative bet on Japanese consumption rather than a high octane growth play. That caution has been rewarded more than punished. Based on exchange data compiled from Yahoo Finance and other quote services, Ito En’s stock closed roughly 15 to 20 percent lower one year ago compared with its latest close. The exact figures vary slightly across providers, but the directional message is clear: the past twelve months have delivered a solid, mid teens percentage gain for patient shareholders.

What does that mean in real money terms? A hypothetical investor who had committed the equivalent of 10,000 units of local currency to Ito En a year ago would now sit on a position worth roughly 11,500 to 12,000, before dividends and trading costs. That is not the kind of windfall that turns heads on social media, yet in the context of a choppy global consumer landscape and lingering inflation in input costs, it reflects impressive capital preservation with a respectable kicker. The ride has not been entirely smooth, with pullbacks during broader Japanese equity corrections, but the long term trajectory still tilts decisively upward.

For investors who stepped in near last year’s lows, the performance looks even better when viewed against Ito En’s 52 week range. The share price currently trades close to the upper half of that band, comfortably above the 52 week low and below but not far from the 52 week high. That position within the range suggests that while the easy money from the recovery phase may already be made, the stock has avoided the kind of frothy overextension that often precedes sharp reversals.

Recent Catalysts and News

In terms of fresh headlines, the past several days have been relatively subdued for Ito En. A targeted search across major business outlets and Japanese market coverage turns up no blockbuster announcements such as transformative acquisitions or radical management changes in the very recent past. Instead, the narrative revolves around incremental developments: ongoing product refreshes in the ready to drink green tea segment, marketing efforts around functional beverages and continued discipline in cost management amid elevated raw material and logistics expenses.

Earlier this week, local coverage and industry commentary focused more on sector level trends than on Ito En specifically. Rising attention to healthier, low sugar drinks and sustained interest in green tea based beverages continues to favor Ito En’s core franchise. The company appears to be leaning into this tailwind with product line extensions and packaging innovations rather than radical repositioning. At the same time, commentary from Japanese equity strategists highlights that food and beverage names such as Ito En are benefiting from investors rotating toward defensive growth while keeping a close eye on yen fluctuations that can affect imported ingredient costs.

Looking slightly beyond the very latest headlines and into the recent quarter, Ito En’s results have generally reinforced this picture of measured momentum. Revenue growth has been supported by both volume and pricing, though management has acknowledged that passing through higher costs without denting demand remains a delicate balancing act. There has been no sign of a dramatic pivot away from the core tea and beverage business, which remains the economic engine, but rather a continued emphasis on deepening distribution, optimizing vending machine networks and fine tuning the product mix for profitability.

Wall Street Verdict & Price Targets

When it comes to external opinions, Ito En does not command the same level of global analyst coverage as mega cap tech or automotive names, yet several major houses keep the stock on their radar. A search across international broker commentary from providers such as Morgan Stanley, UBS and local Japanese brokerages indicates a broadly neutral to moderately positive stance within the last month. The prevailing rating cluster sits around Hold with select Buy recommendations that frame Ito En as a quality defensive play rather than a high growth story.

Recent notes from analysts, as summarized in regional financial media, point to price targets that imply limited but not negligible upside from the current quote. Typical target ranges hover in the mid single digit to low double digit percentage above the latest trading level. Morgan Stanley and UBS, for example, emphasize Ito En’s strong brand equity and stable cash generation, but temper their enthusiasm with references to cost inflation, domestic market saturation and the relatively slow pace of overseas expansion. There is little appetite to slap a Sell label on the stock, yet these institutions also stop short of championing it as a must own outperformer.

This consensus leaves investors with a clear message. At current prices, Wall Street and Tokyo based strategists broadly regard Ito En as fairly valued to slightly undervalued. The stock’s 90 day trend, which shows a gentle upward slope rather than a sharp spike, reinforces this notion of gradual appreciation rather than speculative frenzy. For portfolio builders, that makes Ito En a candidate for the core defensive sleeve more than a tactical trading vehicle.

Future Prospects and Strategy

Underneath the share price sits a business model that is remarkably simple to describe yet difficult to replicate. Ito En is, at its heart, a beverages company built on Japanese tea culture. It has turned green tea and related drinks into a scalable, highly recognizable product family across supermarkets, convenience stores and vending machines. The company also extends into tea leaves and allied products, but the ready to drink segment is the centerpiece of both revenue and investor attention.

Looking ahead to the coming months, several factors will shape Ito En’s trajectory. First, input cost dynamics matter. Any easing in packaging and logistics expenses would flow quickly into margins, especially if the company can hold the pricing gains it has already pushed through. Second, currency moves remain a double edged sword, influencing both imported costs and the translation of any overseas earnings. Third, domestic demand for healthier beverages provides a structural tailwind, but the pace and profitability of international expansion will determine whether Ito En can accelerate growth beyond its home market baseline.

The technical picture complements this fundamental story. The five day performance shows a modest gain, reflecting gentle buying interest rather than a speculative surge, while the broader 90 day trend captures a slow grind higher from previous consolidation levels. Volatility has been contained, suggesting that short term traders are not dominating the shareholder register. If the company can deliver another stable earnings print and demonstrate continued discipline on costs, the stock appears well placed to continue this steady ascent, albeit without dramatic re rating.

For investors, the key question is simple: is a high quality, defensive Japanese beverage champion with mid teens one year gains and a calm chart worth holding at current levels? The answer likely depends on portfolio context. For those seeking explosive growth, Ito En may look too measured. For those seeking resilient cash flows, brand strength and a relatively predictable earnings stream in a turbulent world, the market’s current, cautiously bullish stance on Ito En might feel exactly right.

Losing weight is challenging, and many people turn to weight-loss supplements to help achieve their goals. Unfortunately, many supplements marketed for weight loss don’t do what they promise—and may even work against your goals. Not only are supplements expensive, but they are also unregulated, so you don’t always know what you’re getting. The best way to lose weight is to focus on a food-first approach, which means eating plenty of nutrient-dense foods and maintaining a slight calorie deficit over time. 

In this article, we get into some popular weight-loss supplements and why nutrition professionals don’t recommend them, plus helpful tips for healthy, sustainable weight loss. Knowing what to watch out for can help you make informed choices and prioritize strategies that actually support your health and weight-loss journey.

Green Coffee Bean Extract

If you’ve searched for supplements aiding weight loss, you’ve likely come across green coffee bean extract. Quite simply, this supplement is derived from the coffee plant’s seeds, which are green before roasting. “[Green coffee bean extract] has chlorogenic acid, a coffee compound that can supposedly decrease fat absorption and speed up metabolism,” says Danielle VenHuizen, M.S., RDN. She adds that these claims are mostly unwarranted. 

Only a few human trials have examined the effectiveness of green coffee bean extract on weight loss. These trials had poor study design and showed mixed results. While one study found that green coffee extract may help reduce weight and body mass index, there wasn’t a significant effect on body fat percentage, meaning that the mass lost could come from water or muscle.

Body mass index (BMI) is a flawed measure that’s often used in healthcare to determine a person’s body weight category, and therefore, chronic disease risk. However, it has limitations and does not account for individual factors that influence one’s health status, such as body composition, ethnicity, race, sex and age. This is why it shouldn’t be used as a comprehensive measure of someone’s health and can be a source of body size stigma and bias.

“Additionally, in my clinical experience, I have yet to meet a client who has lost weight by using green coffee bean extract,” says VenHuizen. Lastly, there isn’t much information on the safety of green coffee bean extract, so buyers beware. 

Garcinia Cambogia

Garcinia cambogia is a fruit with ​​hydroxycitric acid (HCA), a compound thought to reduce fat production in the body and suppress appetite. “Studies seem to indicate that some of these claims might be true, but unfortunately, the benefits are modest, and the research is conflicting,” says VenHuizen. One study states that there are only a small number of studies on Garcinia cambogia, and the methodology is poor, meaning that these results shouldn’t be trusted.

Even more alarming, “several studies have reported liver issues with long-term use of this supplement,” says VenHuizen. This is another pretty convincing reason to avoid adding this supplement to your weight-loss regimen. 

Raspberry Ketone

Raspberry ketone is a compound found in the raspberry fruit. Small test-tube and animal studies suggest it may suppress the buildup of fat in the body, but the results are extremely limited. There has only been one human study on the effects of raspberry ketone on weight loss. The participants took the supplement for eight weeks while also following a calorie-restricted diet. The raspberry ketone supplement was combined with caffeine, bitter orange, ginger, garlic, cayenne, L-theanine, pepper extract, B vitamins and chromium. 

The 45 participants who finished the study lost weight, but it’s impossible to know if it was due to the raspberry ketone blend or the calorie deficit. In short, there isn’t enough evidence to support raspberry ketone for weight loss, so save your money. Instead, we recommend snacking on some raspberries, which have several health benefits, including filling fiber and inflammation-fighting anthocyanins.

Caffeine

The most recognizable supplement on this list, caffeine is a compound that stimulates the nervous system. It’s naturally present in tea, coffee and chocolate, as well as in herbal supplements like guarana. Caffeine increases thermogenesis, the body’s natural production of heat. During this process, the body burns extra calories. 

Research suggests caffeine can help with weight loss, but a large dose is necessary to create a response. One study concluded that more than 3 milligrams of caffeine per kilogram of body weight is necessary to stimulate the breakdown of fat. For a 150-pound person, that’s 200 mg of caffeine, or two cups of coffee. 

It is recommended to cap caffeine consumption 400 mg daily for safety, but everyone has a different tolerance level. People sensitive to caffeine may experience symptoms like nervousness, jitters, heart racing and headaches, among others. 

Although caffeine may increase fat loss, it’s not the best way to lose weight, especially because supplements with caffeine may contain more than that, plus other stimulants. That said, caffeine from natural sources like coffee is the safest way to consume caffeine. So, feel free to include a cup of coffee or tea in your day for an energy boost, but don’t expect it to affect your weight too much. 

Tips for Healthy Weight Loss 

Although they may not be quick or flashy, the most effective tools for losing weight are good old-fashioned healthy eating and exercise. VenHuizen recommends increasing fiber-rich fruits and vegetables and healthy fats in the diet. “These foods naturally increase satiety and provide anti-inflammatory benefits that may aid in weight loss,” says VenHuizen. “And unlike supplements, studies on fruit and vegetable intake show that these foods improve weight-loss efforts,” she adds. 

In addition, “Trying to stay moderately active throughout the day, especially for people who work sedentary desk jobs, can help with weight loss,” says Madeleine Putzi, M.S., RDN. She recommends getting up and walking around once per hour to increase your total amount of steps for the day, which is an easy and non-taxing way to increase your daily calorie burn. 

Putzi also suggests investing in a standing desk and/or a walking pad if possible. “If you walk for 10 minutes at 3 miles per hour, you will hit around 1,000 steps. Do that every hour, and that’s an easy 8,000 steps by the end of your workday,” says Putzi.

Our Expert Take

Weight-loss supplements are usually not worth the expensive price tag. If a supplement promises to “magically burn fat or flatten your belly,” chances are it’s not the miracle that’s promised on the bottle. A food and exercise approach to weight loss is the most effective way to reach your weight-loss goals in a sustainable way.

Colostrum is often called “liquid gold” by lactation specialists, midwives and infant-health researchers. It’s the early milk produced in the first days after childbirth: thick, yellow and rich in antibodies, proteins and nutrients.

Newborn babies benefit greatly from it because their immune systems are not yet fully developed and their stomachs can only hold very small amounts. For babies, there’s no debate: colostrum is incredibly beneficial.

But some wellness brands are marketing colostrum to adults. Kourtney Kardashian Barker’s Lemme range sells it as sweet gummies, a sugar-free liquid supplement and creamer.

The appeal is easy to understand. Colostrum has a powerful reputation in infant health. If it protects newborns, many assume it must offer something extraordinary for adults too – but does it?

Babies and adults have very different nutritional needs. A newborn’s stomach holds only a few millilitres, and their immune system is immature. Colostrum provides highly concentrated immune and nutritional factors that the baby needs in its first days of life.

Adults, by contrast, have fully developed digestive and immune systems and can obtain nutrients from a varied diet. An adult stomach holds around one to one-and-a-half litres and expands further after eating. What is essential for a baby is not automatically useful or necessary for an adult body.

While colostrum has undeniable benefits in early life, the versions sold to adults are processed, flavoured and taken in much smaller amounts. That’s why it’s important to look closely at what these products contain and what their marketing suggests they can do.

Colostrum-based supplements are often promoted using persuasive wellness language and health-related suggestions, but scientific evidence for their effectiveness in adults remains limited, early and often based on small studies involving specific groups rather than healthy people. Here’s a closer look at the ideas behind some of these marketing messages and what research actually tells us.

Gut health, digestion and reduced bloating

Some small studies suggest that bovine colostrum might reduce temporary increases in intestinal permeability, sometimes called “leaky gut”, where the lining of the intestine becomes less effective at keeping out bacteria and toxins. These changes can occur after intense exercise or when taking non-steroidal anti-inflammatory medicines, drugs that can irritate the stomach and gut lining.

However, these studies involved only a small number of participants in specific contexts, not healthy adults in everyday life. The findings are considered preliminary and would require larger, well-designed clinical trials before any conclusions could be drawn about general digestive benefits.

The prebiotic fibres inulin and xylooligosaccharides, sometimes added to supplements, are much better studied. Inulin has been shown to increase levels of beneficial gut bacteria such as bifidobacteria, while xylooligosaccharides have been linked to greater bacterial diversity and small improvements in markers related to bowel health, obesity and type 2 diabetes in early research.

But these fibres are not unique to colostrum-based products. They also occur naturally in foods such as onions, garlic, leeks, bananas and chicory root and are widely available as standalone fibre supplements.

Immune system support

Colostrum helps newborns develop immunity by providing antibodies at a time when their immune systems are still forming. This does not mean that taking colostrum will strengthen a healthy adult’s immune system.

The idea of “boosting” immunity – a phrase used in promotional material for Kardashian Barker’s Lemme colostrum supplements – is common in wellness marketing, but it can be misleading.

A healthy immune system doesn’t usually need boosting, and an overactive one can cause harm by attacking the body’s own tissues, as happens in autoimmune conditions such as type 1 diabetes or rheumatoid arthritis.

Some research has explored the potential of bovine colostrum in specific conditions, such as ulcerative colitis and travellers’ diarrhoea. But these studies are small, focus on people who are already unwell and cannot be generalised to the wider population. Anyone with health concerns should seek medical advice before taking any supplement.

In Lemme’s products, references to immune support appear to rely primarily on vitamin D. Vitamin D does help regulate the immune system and supports bone health, and low levels are common in winter or in people with limited sunlight exposure. However, vitamin D is inexpensive and widely available as a standalone supplement.

“Full body wellness”

This is a broad phrase without a specific scientific definition. On the Lemme website, the company states that vitamin D supports healthy bones and teeth, which is accurate, but that benefit is not unique to its colostrum products.

“Glowing skin”

This phrase has appeared in some advertising coverage but not on the official product page. “Glowing skin” has no clinical definition and no standard method of measurement. There’s currently no evidence that colostrum, or any of the ingredients in these supplements, produces this effect.

How language influences trust

Lemme’s website includes the standard disclaimer found on most dietary supplements, stating that the products are not intended to diagnose, treat, cure or prevent disease.

The brand also describes its ingredients as “clinically studied.” This is not the same as “clinically proven.” The phrase typically means that an ingredient has been tested in some form of study, but it does not indicate whether the results were positive, significant or relevant to human health.

Research shows that consumers often confuse these terms. It sounds scientific, but does not demonstrate proven efficacy.

Colostrum is extraordinary for newborns. Nature designed it to protect babies during their most vulnerable days. For adults, however, there is no strong evidence from large, well-designed trials that colostrum supplements improve skin, digestion or immunity in healthy individuals. Some ingredients in these products may show potential in specific medical conditions, but that is not the same as demonstrating general wellness effects.

Colostrum supplements primarily market the idea of something pure, powerful and natural. At present, the science does not fully support these suggestions.

Investors hunting for fireworks in Japanese consumer stocks will not find a spectacle in Ito En right now, but the market’s message is quietly constructive. The tea and beverage specialist has edged up over the past several sessions, extending a steady medium term advance while avoiding the sharp swings seen elsewhere in the food and drink space. The tone around the stock is neither euphoric nor fearful. Instead, Ito En sits in that intriguing middle ground where resilient fundamentals and modest valuation upside coexist with very real margin and FX risks.

One-Year Investment Performance

A year ago, buying Ito En looked like a conservative bet on Japanese consumption rather than a high octane growth play. That caution has been rewarded more than punished. Based on exchange data compiled from Yahoo Finance and other quote services, Ito En’s stock closed roughly 15 to 20 percent lower one year ago compared with its latest close. The exact figures vary slightly across providers, but the directional message is clear: the past twelve months have delivered a solid, mid teens percentage gain for patient shareholders.

What does that mean in real money terms? A hypothetical investor who had committed the equivalent of 10,000 units of local currency to Ito En a year ago would now sit on a position worth roughly 11,500 to 12,000, before dividends and trading costs. That is not the kind of windfall that turns heads on social media, yet in the context of a choppy global consumer landscape and lingering inflation in input costs, it reflects impressive capital preservation with a respectable kicker. The ride has not been entirely smooth, with pullbacks during broader Japanese equity corrections, but the long term trajectory still tilts decisively upward.

For investors who stepped in near last year’s lows, the performance looks even better when viewed against Ito En’s 52 week range. The share price currently trades close to the upper half of that band, comfortably above the 52 week low and below but not far from the 52 week high. That position within the range suggests that while the easy money from the recovery phase may already be made, the stock has avoided the kind of frothy overextension that often precedes sharp reversals.

Recent Catalysts and News

In terms of fresh headlines, the past several days have been relatively subdued for Ito En. A targeted search across major business outlets and Japanese market coverage turns up no blockbuster announcements such as transformative acquisitions or radical management changes in the very recent past. Instead, the narrative revolves around incremental developments: ongoing product refreshes in the ready to drink green tea segment, marketing efforts around functional beverages and continued discipline in cost management amid elevated raw material and logistics expenses.

Earlier this week, local coverage and industry commentary focused more on sector level trends than on Ito En specifically. Rising attention to healthier, low sugar drinks and sustained interest in green tea based beverages continues to favor Ito En’s core franchise. The company appears to be leaning into this tailwind with product line extensions and packaging innovations rather than radical repositioning. At the same time, commentary from Japanese equity strategists highlights that food and beverage names such as Ito En are benefiting from investors rotating toward defensive growth while keeping a close eye on yen fluctuations that can affect imported ingredient costs.

Looking slightly beyond the very latest headlines and into the recent quarter, Ito En’s results have generally reinforced this picture of measured momentum. Revenue growth has been supported by both volume and pricing, though management has acknowledged that passing through higher costs without denting demand remains a delicate balancing act. There has been no sign of a dramatic pivot away from the core tea and beverage business, which remains the economic engine, but rather a continued emphasis on deepening distribution, optimizing vending machine networks and fine tuning the product mix for profitability.

Wall Street Verdict & Price Targets

When it comes to external opinions, Ito En does not command the same level of global analyst coverage as mega cap tech or automotive names, yet several major houses keep the stock on their radar. A search across international broker commentary from providers such as Morgan Stanley, UBS and local Japanese brokerages indicates a broadly neutral to moderately positive stance within the last month. The prevailing rating cluster sits around Hold with select Buy recommendations that frame Ito En as a quality defensive play rather than a high growth story.

Recent notes from analysts, as summarized in regional financial media, point to price targets that imply limited but not negligible upside from the current quote. Typical target ranges hover in the mid single digit to low double digit percentage above the latest trading level. Morgan Stanley and UBS, for example, emphasize Ito En’s strong brand equity and stable cash generation, but temper their enthusiasm with references to cost inflation, domestic market saturation and the relatively slow pace of overseas expansion. There is little appetite to slap a Sell label on the stock, yet these institutions also stop short of championing it as a must own outperformer.

This consensus leaves investors with a clear message. At current prices, Wall Street and Tokyo based strategists broadly regard Ito En as fairly valued to slightly undervalued. The stock’s 90 day trend, which shows a gentle upward slope rather than a sharp spike, reinforces this notion of gradual appreciation rather than speculative frenzy. For portfolio builders, that makes Ito En a candidate for the core defensive sleeve more than a tactical trading vehicle.

Future Prospects and Strategy

Underneath the share price sits a business model that is remarkably simple to describe yet difficult to replicate. Ito En is, at its heart, a beverages company built on Japanese tea culture. It has turned green tea and related drinks into a scalable, highly recognizable product family across supermarkets, convenience stores and vending machines. The company also extends into tea leaves and allied products, but the ready to drink segment is the centerpiece of both revenue and investor attention.

Looking ahead to the coming months, several factors will shape Ito En’s trajectory. First, input cost dynamics matter. Any easing in packaging and logistics expenses would flow quickly into margins, especially if the company can hold the pricing gains it has already pushed through. Second, currency moves remain a double edged sword, influencing both imported costs and the translation of any overseas earnings. Third, domestic demand for healthier beverages provides a structural tailwind, but the pace and profitability of international expansion will determine whether Ito En can accelerate growth beyond its home market baseline.

The technical picture complements this fundamental story. The five day performance shows a modest gain, reflecting gentle buying interest rather than a speculative surge, while the broader 90 day trend captures a slow grind higher from previous consolidation levels. Volatility has been contained, suggesting that short term traders are not dominating the shareholder register. If the company can deliver another stable earnings print and demonstrate continued discipline on costs, the stock appears well placed to continue this steady ascent, albeit without dramatic re rating.

For investors, the key question is simple: is a high quality, defensive Japanese beverage champion with mid teens one year gains and a calm chart worth holding at current levels? The answer likely depends on portfolio context. For those seeking explosive growth, Ito En may look too measured. For those seeking resilient cash flows, brand strength and a relatively predictable earnings stream in a turbulent world, the market’s current, cautiously bullish stance on Ito En might feel exactly right.
