PRODUCT LABEL

Nutristat Magnesium Bisglycinate

Magnesium in the bisglycinate form — magnesium bonded to two glycine molecules.

Why the form matters more with magnesium than almost anything

Magnesium is sold in many forms at wildly different prices, and the differences are real rather than marketing.

Bisglycinate	Well absorbed, gentle on the stomach	The one most people should buy
Citrate	Reasonably absorbed, mildly laxative	Fine, and useful if constipation is an issue
Malate	Well absorbed	Sometimes preferred for daytime use
Oxide	Poorly absorbed, strongly laxative	The cheap one in supermarket products

Magnesium oxide is roughly 60% magnesium by weight, which looks excellent on a label. But absorption is poor, and the unabsorbed portion draws water into the bowel — which is exactly why magnesium oxide is sold as a laxative.

So when someone says magnesium upsets their stomach, it is usually not magnesium. It is that form of magnesium.

What bisglycinate specifically does

Chelation is the mechanism. Bonding magnesium to two glycine molecules means it is absorbed through the amino acid pathway — a separate, far higher-capacity route than the limited mineral transporters, and one that avoids competition with other minerals.

Better absorbed means less left in the gut, which means no laxative effect.

And the glycine is not merely a carrier. Glycine is itself an inhibitory neurotransmitter with its own research in sleep quality. So the bisglycinate form arguably delivers two things relevant to evening use — which is why it is the form most commonly recommended for sleep.

Magnesium is genuinely one to supplement

We are sceptical of most "everyone is deficient" claims. Magnesium is a fair exception.

Dietary surveys consistently find a large share of adults below the recommended intake, and the reasons are structural: magnesium concentrates in leafy greens, nuts, seeds and whole grains, and food refining strips most of it out.

What it does:

Energy production. ATP is biologically active as Mg-ATP — bound to magnesium. Without it, ATP does not function
Muscle relaxation. Calcium triggers contraction; magnesium governs the relaxation that follows. That balance is why deficiency is linked to cramping and twitching
Sleep and stress. Magnesium supports the calming side of the nervous system, modulating NMDA receptor activity and GABAergic signalling
Nerve transmission, and bone — around 60% of body magnesium is stored there
More than 300 enzymatic reactions overall

Athletes lose more of it. Magnesium is excreted in sweat and urine, and hard training raises turnover.

Specs

Magnesium	Bisglycinate (chelated)
Absorption	Amino acid pathway — high capacity, no mineral competition
Laxative effect	Minimal, unlike oxide
Stimulants	None

How to take it

Evening is the sensible default, for sleep and muscle relaxation.
With or without food. Chelated forms do not need a meal.
Daily. Magnesium status corrects gradually over weeks, not overnight.
Away from high-dose calcium or zinc if you take those separately — chelation largely removes competition, but spacing is tidier.
⚠ Away from antibiotics and thyroid medication by several hours — magnesium interferes with absorption of both. Check with your pharmacist.

Who this is for

Anyone who cramps or twitches
People who train hard and sweat heavily
Anyone who has tried cheap magnesium and had loose stools — this is the direct solution
People taking it for sleep, where the glycine adds something
Anyone whose diet is light on leafy greens, nuts and seeds

Who this is not for

If you specifically want the laxative effect, magnesium citrate or oxide does that job more cheaply.

If you want magnesium combined with zinc and B6, a ZMA product covers all three.

⚠ Speak to your doctor if you have kidney disease. Impaired kidneys cannot clear excess magnesium, and that is a genuine caution.

Not for anyone under 18, pregnant or nursing.

Stack it with: zinc and vitamin D — the three nutrients most commonly low in active people. Take zinc away from this one.

Frequently asked questions

Why bisglycinate rather than oxide?
Oxide is poorly absorbed and the unabsorbed portion draws water into the bowel, which is why it works as a laxative. Bisglycinate is absorbed via the amino acid pathway and is gentle.

Does magnesium help sleep?
It supports the calming side of the nervous system, and the glycine in bisglycinate has its own sleep research — which is why this form is the one usually recommended for evening use.

When should I take it?
Evening, with or without food.

Will it help cramps?
Possibly. Magnesium governs muscle relaxation, and cramping is a commonly reported sign of low status — though it is not the only cause.

Am I likely to be short of magnesium?
Quite possibly. Dietary surveys consistently find a large share of adults below the recommended intake, and food refining strips it out.

Any medication interactions?
Magnesium interferes with absorption of some antibiotics and thyroid medication — space them several hours apart and ask your pharmacist.

How long before it works?
Status corrects over weeks. Sleep effects are sometimes noticed sooner.

Can I take too much?
Excess is usually excreted, though large doses cause loose stools. Speak to your doctor first if you have kidney disease.
