The Science Behind Mayntain: Why These Specific Ingredients for GLP-1 Users

There's no shortage of supplements on the market. So why Mayntain? And why these specific ingredients, at these specific doses?

The answer starts with a simple observation: people on GLP-1 medications like Mounjaro and Zepbound face a very specific challenge. They eat significantly less — often 30–50% less than before — which means their intake of protein, fibre, vitamins and minerals drops sharply at exactly the time their body is undergoing rapid, demanding change.

Mayntain Daily was built around one central question: what does the body of a GLP-1 user need most that they're no longer getting from food? Below we explain, ingredient by ingredient, why each one is in the formula.

The Core Ingredients and Why They're Included

Akkermansia muciniphila — 100 million CFU

Akkermansia is one of the most studied gut bacteria in relation to metabolism and weight. It lives in the protective mucus layer of the gut wall and plays a role in maintaining a healthy gut barrier. When food intake drops sharply — and with it fibre and dietary variety — the balance of the gut flora can come under pressure. Mayntain includes a targeted dose of Akkermansia to support the gut flora during a period of rapid change.

Hydrolysed collagen peptides — 500 mg

Collagen is the most abundant protein in the body and a building block of skin, hair, nails, joints and connective tissue. When total protein intake falls — almost unavoidable with a strongly suppressed appetite — the body receives fewer of the amino acids it needs for repair and maintenance. Hydrolysed peptides are broken down into shorter chains, making them easy to absorb.

Psyllium (fibre) — 500 mg

Psyllium is a soluble fibre that binds water in the digestive tract. Fibre is among the first things to disappear when someone eats far less, even though it is important for normal bowel function and a feeling of fullness. Psyllium helps keep fibre intake up during a phase when food intake is minimal.

Magnesium bisglycinate — 200 mg

Magnesium is involved in hundreds of processes in the body, including a normal energy metabolism, normal muscle and nervous-system function, and the reduction of tiredness and fatigue. It is one of the minerals that falls short most quickly on a calorie-restricted diet. We deliberately chose the bisglycinate form, which is gentle on the stomach and well absorbed.

Vitamin D3 — 1000 IU (25 mcg)

Vitamin D contributes to the normal function of the immune system, the maintenance of strong bones and normal muscle function. It occurs naturally in few foods (oily fish, egg yolk, fortified products), so dietary intake is often already low — especially when you're eating less.

Vitamin B12 — 500 mcg

Vitamin B12 contributes to a normal energy metabolism, the formation of red blood cells and a normal nervous-system function. B12 comes mainly from animal products and is easily squeezed out by smaller portions, which can contribute to a tired feeling.

Biotin (vitamin B7) — 5000 mcg

Biotin contributes to the maintenance of normal hair, normal skin and a normal energy metabolism. It plays a role in the production of keratin, the structural protein of hair. Biotin is found mainly in foods that are often eaten less when appetite is suppressed, such as eggs and nuts.

Zinc bisglycinate — 10 mg

Zinc contributes to the maintenance of normal hair, normal skin and nails, and a normal immune system function. It is a cofactor in countless enzymatic processes involved in cell division and repair. Zinc is one of the minerals most often depleted during rapid weight loss. We use the well-absorbed bisglycinate form.

What Mayntain Deliberately Leaves Out

Mayntain is not a general multivitamin. We don't add iron (which should be supplemented based on individual assessment), no high-dose stimulants and no fillers without purpose. The formula is deliberately focused on the nutrients and gut support most relevant to GLP-1 users.

Made in Europe. Chosen on the evidence.

Mayntain is manufactured in Europe under strict quality standards. Every ingredient is selected based on its role in the challenges that come with sharply reduced food intake and GLP-1 medication.

On Mounjaro or Zepbound? Then your body is working hard. Mayntain Daily is designed to support it with exactly what you're getting less of from food.

Food supplements are not a substitute for a varied diet and a healthy lifestyle. If you have a medical condition or take medication, consult your doctor or pharmacist.
