Marks & Spencer is launching a range of foods tailored to people taking weight-loss injections as use of the drugs accelerates in the UK.

The new range of 20 “nutrient-dense” products from the retailer is aimed at customers taking GLP-1 weight-loss medications, as supermarkets increasingly adapt to the impact the drugs are having on shopping baskets.

The range will go on sale in M&S foodhalls from January 5 and includes salads, meals and bread designed to deliver high levels of fibre, vitamins and minerals in smaller portions.

There has been a dramatic rise in the use of GLP-1 drugs in the UK. Online searches and private prescriptions have increased sharply, driven by their effectiveness for weight loss and widespread media attention. About 1.5 million people in the UK are now estimated to be accessing GLP-1 treatment privately, while NHS England prescriptions for the injections have risen by around 900 per cent since 2020.

GLP-1 medications — known formally as glucagon-like peptide-1 (GLP-1) receptor agonists — were originally developed to treat type 2 diabetes by helping to regulate blood sugar. In recent years, drugs such as semaglutide (sold as Ozempic for diabetes and Wegovy for weight loss) and tirzepatide (sold as Mounjaro) have surged in popularity for their weight-loss effects, as they suppress appetite, slow digestion and signal fullness to the brain.

Nutrient-dense foods are those that provide a concentrated source of vitamins, minerals, fibre, healthy fats and protein relative to their calorie content. M&S said the range was developed by its nutritionists in consultation with the British Nutrition Foundation, using criteria that ensure each product delivers more nutrients per mouthful.

M&S said the new range had been developed to address the nutritional challenges that can arise when people eat less, whether due to medication, age or lifestyle. A reduced appetite can make it harder to consume enough fibre and essential nutrients, increasing the risk of deficiencies and digestive side effects such as constipation.

Grace Ricotti, M&S head of food nutrition, said: “Our nutrient-dense range is perfect for customers looking to support their health as each recipe is packed with the key nutrients we all need in our diets.

“With the increase in popularity of weight-loss injections, a reduced appetite can mean missing out on important nutrients and that’s why nutrient density is so important.

“These new meals, snacks and drinks can help everyone get more fibre, vitamins and minerals in their diet.”

Supermarkets and consumer goods companies are increasingly catering to households using the drugs. Morrisons was the first UK supermarket to announce a dedicated “GLP-1 friendly” range, developed with sports nutrition brand Applied Nutrition, under its “Small & Balanced” banner. Nestlé, the consumer goods giant, has launched a frozen food brand in the US aimed at GLP-1 users, while Haleon, the British multinational consumer healthcare company, has introduced a multivitamin designed to help replenish nutrients for people eating less.

The trend is expected to accelerate further as GLP-1 medications move beyond injections. Tablet versions are beginning to reach the market, with US regulators approving an oral version of Wegovy and rival pills expected to follow, potentially widening access to the drugs.

While the drugs are approved for diabetes and obesity treatment, clinicians have raised concerns about the number of people accessing them outside clinical pathways for cosmetic weight loss. The long-term consequences of widespread use are still being studied, particularly as lower calorie intake can increase the risk of nutrient deficiencies if diets are not carefully managed.

Many people with diabetes or prediabetes try supplements to help control their blood sugar. However, some supplements can change how prescription diabetes drugs work—either by lowering blood sugar too much, or by affecting how much your body absorbs the drug.

1. Berberine

Berberine can add to metformin’s effects, meaning stronger glucose-lowering and gastrointestinal (GI) effects

Berberine (from plants such as Berberis) has blood sugar (glucose)-lowering effects and is sometimes used as a “natural” alternative to metformin.

Studies and reviews have shown similar mechanisms between berberine and metformin. For example, both can help reduce the amount of glucose produced by your liver. This can lead to additive or synergistic effects when taken together, so your blood sugar may drop too low. The similar effects also mean that GI side effects can be worsened.

Talk to your healthcare provider before planning to take berberine. If you are also taking metformin or another glucose-lowering medication, you may need to closely monitor your blood sugar levels and review your dosing with your provider.

2. Cinnamon

Cinnamon can increase the risk of low blood sugar when combined with medications.

Cinnamon and cinnamon extracts have been reported in multiple trials and reviews to modestly lower fasting glucose and hemoglobin A1c (average blood sugar level over two or three months) in some people.

This effect means that cinnamon supplements can enhance the glucose-lowering effect of prescription medications, such as sulfonylureas or insulin, especially when taken in concentrated form rather than as a sprinkle of the spice. 

Clinical evidence is mixed, but caution is warranted. “Natural” doesn’t mean harmless, and you should check your blood glucose more often if you start taking a cinnamon supplement.

3. Ginseng

Unpredictable effects mean ginseng may increase or decrease the effect of prescription diabetes medications.

Different ginseng preparations (e.g., American, Asian) and study designs produce inconsistent results, but studies show that ginseng can affect insulin secretion, glucose uptake, and postprandial (after a meal) glucose.

In individuals already taking oral blood sugar-lowering drugs or insulin, ginseng may have the potential to cause additive glucose-lowering effects, which can lead to hypoglycemia (too low blood sugar), or alter their responses to these medications.

Commercial ginseng products can vary widely in potency and formulation. Be sure to consult with your healthcare provider before starting this supplement.

4. St. John’s Wort

St. John’s wort may change drug metabolism, affecting how much of your diabetes medications get absorbed.

St. John’s wort increases the activity of CYP3A4 (a drug-metabolizing enzyme in the body) and certain drug transporters (proteins responsible for drug absorption, distribution, and elimination). As a result, it can reduce the blood levels of medications that share these pathways. For this reason, it is notorious for interacting with many different medications. 

While many diabetes drugs do not get broken down by the CYP3A4 enzyme, St. John’s wort has been shown to alter the way metformin works in your body in at least one trial. It can also interact with many other medications.

Because of its unpredictability with interactions, it’s recommended to avoid combining St. John’s wort with complex medication regimens without supervision from your healthcare provider.

5. Aloe Vera

Aloe vera can lower glucose and interact with diabetes medications.

Aloe vera has been studied for its effects on processes that contribute to high blood sugar levels. Studies suggest that it may be beneficial in reducing fasting glucose and hemoglobin A1c levels, particularly in stabilizing blood sugar levels after meals.

However, the extent to which aloe vera affects blood sugar levels is unknown. Tell your healthcare provider if you are taking an aloe vera supplement. Keep in mind that aloe vera formulations also vary, and some can cause side effects, such as GI upset.

6. Chromium

Chromium supplementation has shown modest improvements in insulin sensitivity and hemoglobin A1c in some studies. Other studies have shown benefit only in people with poor nutritional status or already low chromium levels. 

Because chromium can enhance insulin action, using it with a prescription blood sugar-lowering drug can raise the risk of hypoglycemia, especially if the doses are higher than those found in multivitamins.

According to the Food and Drug Administration (FDA) and the Institute of Medicine, it is safe when taken at a dose of 200 micrograms daily for up to six months.

Keep in mind, chromium supplements may also carry side effect risks like GI upset or headaches. Caution should be used if you have kidney or liver issues. Talk to your healthcare provider about whether chromium supplements may be beneficial for you.

The popularity of matcha continues to boom. But recent videos on social media have suggested it could be bad for you if you have low iron.

One Sydney woman recently told media she had “no idea” her daily matcha latte could affect her health until she started experiencing headaches, and noticed her hair and nails were brittle and she was bruising easily. Blood tests found she was severely low in iron.

Similar videos on TikTok show women in hospital getting iron transfusions — and blaming their matcha habit.

So, let’s unpack this. How healthy is matcha? And can it really cause low iron?

What is matcha?

Matcha is a fine powder made from dried and ground-up green tea (Camellia sinensis) leaves. It has recently gained popularity as a drink and a flavor variety in many different foods.

Matcha contains many beneficial compounds (for example, dietary fiber and polyphenols) as well as being a source of caffeine.

Including matcha, or green tea, as part of a balanced diet may provide health benefits such as supporting healthy brain function and blood pressure.

However despite its health benefits, research has shown that drinking a lot of green tea is linked to lower levels of iron in the blood.

We need iron – but can’t make it

Iron is an essential micronutrient that helps transport oxygen around the body, as well as supporting many other important biological processes.

Our bodies can’t make iron, so we need to get it from our diet to support these functions. But even if we eat a lot of iron-rich foods, other things in our diet — such as coffee, red wine, calcium-rich foods and yes, matcha — can interfere with absorbing the iron.

So people with low iron levels need to be careful.

In particular, women who menstruate have an increased risk of low iron because of iron lost through bleeding.

You may have an iron deficiency if your iron falls below certain levels – typically for adults, less than 30 micrograms of iron per liter of blood. There are different cutoffs for children.

Iron deficiency anemia is a condition where very low levels of iron affect the functioning of red blood cells. It is diagnosed based on levels of hemoglobin in the blood (these cutoffs vary by age, sex and pregnancy status).

What does matcha do to iron levels?

There are two main components in green tea that stop us absorbing iron. These are polyphenols and phytic acid (also known as phytate).

Both polyphenols and phytic acid have their own health benefits, for example, protecting against chronic diseases such as type 2 diabetes. But they also bind to iron and prevent it from being absorbed into the body.

So, if you have a lot of food or drink that contains these components — especially in combination with iron-rich foods — they can reduce iron absorption.

However, it’s not only matcha that can interfere. Phytic acids are also found in other teas and many plant foods, such as nuts, cereals and legumes. Tea, coffee, berries, and other fruits and vegetables are also high in polyphenols.

How much matcha will affect your iron levels?

This varies between people.

One study showed people who drink three or more cups of green tea a day had lower blood iron levels than those who drink less than one a day. But they didn’t experience iron deficiency any more often.

However other research has linked moderate green tea consumption (two cups a day) to iron deficiency anaemia.

Whether or not your matcha latte will contribute to an iron deficiency depends on many other factors, including your existing iron levels.

So, what about matcha-flavored foods?

In these — for example, matcha ice cream — the actual amount of green tea powder is very low. This means it’s unlikely to significantly affect iron absorption.

But it’s not just about quantity — when you drink your matcha also matters.

To reduce the impact on iron absorption, it’s recommended you have green tea separately from meals — at least one hour between eating and drinking tea.

What else to keep an eye on

Multiple other factors in your diet can influence iron absorption. What you eat may either exacerbate or counteract the effects of your matcha latte on iron absorption.

Overall, balance is key to ensure you are getting the full spectrum of nutrients the body requires.

To support iron levels, you can incorporate iron-rich foods (such as beans, lentils, meat, fish and fortified cereals) into a healthy diet.

Eating vitamin C-rich foods (such as capsicum, broccoli, kiwifruit and other fruit and vegetables) along with foods that contain iron can help to enhance iron absorption.

If you are concerned about your iron levels, you should speak to a health-care professional — especially if experiencing symptoms of iron deficiency (such as tiredness, weakness or dizziness).

A blood test can diagnose low iron levels. If you have an iron deficiency, your GP or dietitian will help you manage symptoms and work out what is right for you.

People searching for information about GenuinePurity NMN typically want answers to specific questions:

• Is this a legitimate product from a real company?

• Does liposomal NMN address absorption differently than regular NMN capsules?

• What does research indicate about the 250mg dosage level?

• What should I realistically expect if I try it?

• How does pricing compare to other options in this category?

• Are there side effects or safety concerns?

• How long before users typically evaluate whether supplementation aligns with their goals?

This analysis addresses each of these questions with verified information and appropriate context.

The NAD+ Decline Problem: Understanding Why NMN Supplements Exist

Before evaluating any NMN product, understanding the underlying science provides necessary context for what these supplements aim to address.

What Is NAD+ and Why Does It Matter?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every cell of the body. According to published research, NAD+ plays roles in over 400 biological processes, including:

• Cellular energy production — NAD+ is essential for mitochondrial function, the process by which cells generate ATP (cellular energy)

• DNA repair mechanisms — NAD+ activates enzymes called sirtuins and PARPs that help maintain DNA integrity

• Cellular communication — NAD+ serves as a signaling molecule between cells

• Metabolic regulation — NAD+ influences how the body processes nutrients and maintains metabolic function

The Age-Related NAD+ Decline

Research published in peer-reviewed journals has documented that NAD+ levels decline with age. According to a study cited in Integrative Medicine: A Clinician’s Journal, by middle age, NAD+ levels may be approximately half of what they were during youth. This decline has been associated in research literature with various aspects of aging, including reduced energy, slower metabolism, and decreased cellular repair capacity.

A 2022 article in the Journal of Advanced Research noted that NAD+ depletion is associated with “downregulation of energy production in mitochondria, oxidative stress, DNA damage, cognitive impairment and inflammatory conditions.”

This is ingredient-level and general research about NAD+. GenuinePurity Liposomal NMN as a finished product has not been independently clinically studied. Individual responses to supplementation vary significantly.

Why NMN as a Supplement?

The body cannot effectively absorb NAD+ directly when taken orally — the molecule is too large to cross cell membranes efficiently. This is why researchers and supplement formulators have focused on NAD+ precursors: compounds that the body can absorb and then convert into NAD+.

NMN (nicotinamide mononucleotide) is one of the most direct precursors to NAD+. According to research, NMN can be rapidly absorbed and converted to NAD+ through the body’s natural biosynthesis pathways. A frequently cited mechanism paper in Nature Metabolism reported evidence of intestinal NMN uptake involving the Slc12a8 transporter in mouse models, which has influenced how researchers discuss oral NMN absorption pathways.

The 2026 Absorption Discussion: Why Delivery Method Has Become a Central Question

One of the most discussed topics in NMN supplementation heading into 2026 is absorption. Some users report trying NMN supplements and not experiencing expected results, leading to questions about whether delivery method affects outcomes. This has generated significant discussion in longevity communities about different NMN formulation approaches.

The Standard NMN Absorption Consideration

When NMN is taken in standard capsule or powder form, it must navigate the digestive system, where:

• Stomach acids can potentially affect the compound before absorption

• The NMN must cross intestinal membranes to reach the bloodstream

• Some portion of the NMN may be metabolized before reaching target tissues

Research has explored various delivery mechanisms to address these considerations, including sublingual (under-the-tongue) delivery, delayed-release capsules, and liposomal encapsulation.

How Liposomal Technology Works — And Its Research Context

Liposomes are microscopic spheres made of phospholipids — the same material that comprises cell membranes. When NMN is encapsulated within liposomes:

• The lipid layer may protect the NMN from degradation in the stomach

• The liposomes may fuse with cell membranes, potentially facilitating NMN delivery into cells

• The delivery mechanism is designed to align with how the body naturally transports certain compounds between cells

According to research published in Integrative Medicine, the body naturally transports NMN between cells using extracellular vesicles (EVs) that function similarly to liposomes. Adipose tissue actively secretes these vesicles enriched with NMN, which then circulate through plasma to deliver NMN to target tissues. This discovery has informed how some researchers view liposomal NMN formulation approaches. Some researchers and formulators have proposed that vesicle-based delivery may align with naturally occurring extracellular-vesicle transport concepts discussed in the literature, though this remains an evolving area and direct product-to-product comparisons require additional data.

Addressing the Delivery Method Discussion

Some content online discusses whether liposomal NMN offers meaningful advantages over standard NMN, given that clinical studies have used standard formulations successfully. This perspective deserves fair consideration alongside the rationale for liposomal delivery.

Points raised by those questioning liposomal necessity:

• Multiple human clinical trials have used standard NMN powder or capsules and demonstrated NAD+ elevation

• NMN appears to absorb relatively quickly even without liposomal encapsulation

• Liposomal products typically cost more than standard formulations

Research context supporting liposomal approaches:

• According to published research on liposomal delivery systems, phospholipid-based encapsulation has been shown to improve the bioavailability of certain compounds

• While standard NMN can raise NAD+ levels, absorption rates may vary between individuals

• The Slc12a8 transporter that absorbs NMN is primarily active in the small intestine — meaning NMN that is affected in the stomach may have reduced opportunity to reach this transporter

• The body’s own NMN transport system uses liposome-like vesicles, which informs the rationale for this formulation approach

The practical context: For some users, standard NMN produces expected results. For others — particularly those who have tried standard NMN without experiencing anticipated benefits — the absorption variable may be a factor worth considering. GenuinePurity states that its formulation approach is designed to address absorption variability observed with standard NMN supplements, though individual responses vary and comparative outcomes are not guaranteed.

The Dosage Context: Research on 250mg NMN and Bioavailability Considerations

One of the most common questions about GenuinePurity Liposomal NMN concerns its 250mg dose. Some products in this category offer 500mg, 900mg, or higher per serving. Understanding the research context around dosage helps inform evaluation.

What the Clinical Research Indicates About NMN Dosing

A 2024 meta-analysis examining 12 clinical trials found that NMN safely and effectively elevates NAD+ across a range of doses. Research findings include:

• Studies using doses as low as 250-300mg daily have demonstrated measurable effects on NAD+ levels

• A study examining telomere length found that 300mg daily of NMN could affect telomere measurements in blood cells within 90 days

• Research has examined muscle insulin sensitivity and physical performance markers at moderate doses

The research indicates that NMN supplementation at the 250mg level has been studied and has produced measurable outcomes in clinical settings.

The Bioavailability Discussion

Discussions around NMN dosage often include considerations beyond milligram quantity alone, such as delivery method and individual absorption differences. Illustrative bioavailability models are frequently used in academic contexts to explain why moderate doses delivered efficiently may perform differently than higher doses with lower absorption, though direct comparisons require further study.

GenuinePurity states that liposomal delivery may allow for more efficient absorption at moderate doses. This is the company’s formulation rationale, and individual responses to any supplementation approach vary significantly.

The Methyl Donor Consideration

An additional factor that longevity researchers have discussed: high-dose NMN supplementation (particularly above 500-1,000mg daily) may affect methyl donor availability in the body’s NAD+ synthesis pathway. Some researchers recommend pairing high-dose NMN with trimethylglycine (TMG) to support methylation. Moderate-dose NMN supplementation typically does not raise this consideration to the same degree.

GenuinePurity’s Dosage Position

GenuinePurity positions its 250mg dose as:

• Aligned with dosage levels examined in published NMN research

• Formulated with liposomal delivery to address absorption considerations

• Appropriate for consistent long-term use

• Adjustable for those who prefer higher intake (multiple capsules can be taken, which affects supply duration)

For users who have researched NMN and concluded they prefer higher per-serving doses in standard form, other products in this category may align with those preferences. For those who value the liposomal delivery approach and prefer a moderate dose aligned with published research, GenuinePurity’s formulation addresses these considerations.

Understanding Purity Specifications: Context for Evaluating NMN Products

Some consumers comparing NMN products notice different purity specifications across brands. Understanding what purity indicates helps inform product evaluation.

What “Purity” Means in NMN Products

NMN purity refers to the percentage of the active compound (beta-nicotinamide mononucleotide) in the raw ingredient, with the remaining percentage comprising minor compounds from the manufacturing process.

GenuinePurity’s 96% purity level indicates pharmaceutical-grade NMN that meets stringent quality standards. Different products in this category report various purity levels.

The Delivery Context

Purity of the raw ingredient is one factor in evaluating NMN products. Delivery method and individual absorption are additional factors that researchers and formulators consider. GenuinePurity’s formulation approach combines purity specifications with liposomal delivery technology.

Third-Party Verification: The Transparency Standard

What matters alongside purity is verification. GenuinePurity publishes Certificates of Analysis (COA) documenting:

• Third-party laboratory testing confirming purity levels

• Verification of NMN identity (confirming the product contains what it claims)

• Potency confirmation (the 250mg per capsule specification)

• Testing for contaminants, heavy metals, and microbial content

The availability of COA documentation allows consumers to verify product specifications independently.
