Great sleep and no more cramps

Really happy with these - easy to swallow, no stomach upset, and I've noticed better sleep within about a week of taking them daily. Would recommend.

Ash

Noticeably less tired in the afternoons

I've been taking these for about three weeks now and honestly didn't expect much, but I've noticed a real difference in how run-down I feel by mid-afternoon. No aftertaste, easy to swallow, and no stomach issues at all.

Priya

Great quality, easy to recommend

Does exactly what it says on the tin - helps me wind down before bed and I've had zero digestive issues, unlike other magnesium supplements I've tried. Capsules are easy to swallow and I've already recommended it to a couple of friends.

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 glycinate, and more likely to cause a laxative effect at higher doses.

Magnesium Glycinate (ours)

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