Pure Lab Vitamins Magnesium Butyrate Details
Pure Lab Vitamins Magnesium Butyrate 680mg combines butyrate and magnesium in one capsule to help maintain proper gastrointestinal function and gut muscle function. Each capsule provides 600 mg of butyric acid (from magnesium bis-butyrate) and 80 mg of magnesium. Butyrate is a short-chain fatty acid that your gut bacteria normally make when they ferment certain dietary fibres, and the butyrate in this product is sourced from coconut oil. It comes as an encapsulated dry powder in Vegi-Caps — 120 per bottle — which Pure Lab says spares you the mess, excessive odour and faster spoilage risk of liquid products. Vegan, with no gluten, wheat, sugar, yeast, milk, egg, shellfish, soy, corn, preservatives or artificial colours. Made in Canada by Pure Lab Vitamins of Ottawa.

Who Magnesium Butyrate Is For
- Adults and adolescents 9 and over who want to help maintain proper gastrointestinal function
- People looking to support gut muscle function, which Pure Lab ties to healthy motility of the large intestine
- Anyone whose diet is low in the complex carbohydrates and fibre that gut bacteria use to make butyrate
- People who want butyrate in a dry capsule rather than a liquid
- Vegans and those avoiding gluten, soy, corn and dairy
Who this product is NOT for:
- Children under 9 — the label directions are for adolescents (9 years +) and adults
- People who are very sensitive to smells — butyrate has a natural strong odour that may still be noticeable when you open the bottle
- Anyone looking for a general-purpose magnesium supplement — Pure Lab Vitamins Magnesium Glycinate is the better everyday choice
Vitamart's Take
Butyrate is one of the more interesting gut-health ingredients: it's the fuel your colon cells run on, and normally your gut bacteria have to make it from fibre. Pure Lab pairs it with magnesium, which it says relaxes the muscles important to gut motility, so one product covers both the gut lining and the gut muscles. Putting it in a dry capsule is a smart choice — liquid butyrate is notoriously smelly and spoils faster. The odour isn't gone entirely, but it's much easier to live with. A focused, clean, vegan formula made in Canada.
How Magnesium Butyrate Compares
Capsules vs. liquid magnesium butyrate
Butyric acid naturally has a strong odour. Pure Lab encapsulates a dry powder, so the odour may be detectable but is less apparent than with liquid magnesium butyrate products, and there's no mess or faster spoilage risk.
Butyrate vs. fibre supplements
Fibre supplements give your gut bacteria the raw material they ferment into short-chain fatty acids like butyrate. Magnesium Butyrate supplies butyrate itself. Some people use both — browse our Fiber Supplements below.
Magnesium Butyrate vs. Magnesium Glycinate
Pure Lab Vitamins Magnesium Glycinate is a general magnesium supplement. Magnesium Butyrate is gut-focused: the butyrate is the main ingredient, and its 80 mg of magnesium per capsule supports gut muscle function.
What Is Butyrate?
- Butyrate (butyric acid) is a short-chain fatty acid produced when gut bacteria in the large intestine (colon) ferment certain dietary fibres
- Pure Lab describes it as a post-biotic and the main energy source for the cells of the colon
- It helps maintain the integrity of the gut barrier
- A diet low in complex carbohydrates impairs butyrate production, because the bacteria that make it need the fibre found in those foods
- In this product, butyrate is bound to magnesium as magnesium bis-butyrate, sourced from coconut oil
Recommended Purpose
- Helps to maintain proper gastrointestinal function and gut muscle function
How To Use
- Adolescents (9 years +) and adults: take 2 capsules once or twice daily, or as directed by your health practitioner
- Take with water, with or without food
- Do not use if the seal is broken
