Why Magnesium Bisglycinate

Highest bioavailability

Fully chelated, non-buffered Magnesium Bisglycinate — far better absorbed than the cheaper oxide or citrate forms used in most supplements.

Vegan & allergen-free

Suitable for vegans, and free from gluten, soy and dairy.

Gentle, non-laxative

No fillers, binders, or magnesium stearate. Easy-swallow capsules, well tolerated without the laxative effect common with cheaper magnesium.

UK GMP manufactured

Made in the UK in the same GMP-certified facility as Holland & Barrett and GNC.

Not all magnesium is absorbed the same way

Magnesium Oxide

Highest elemental yield on paper (~61%) but only around 4% actual bioavailability — most of it passes straight through you.

Magnesium Citrate

Better absorbed than oxide, but still well below bisglycinate, and more likely to cause a laxative effect at higher doses.

Magnesium Bisglycinate (ours)

Elemental magnesium bonded to glycine amino acids for the highest bioavailability of any common magnesium source — non-laxative, fully chelated.
