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.
