Magnesium Bisglycinate 1000 mg Capsules

Magnesium bisglycinate capsules deliver 1000 mg of magnesium bisglycinate per serving — 140 mg of elemental magnesium — in the chelated form that is easiest on the stomach. Two capsules a day, 120 capsules, a two-month supply.

What magnesium does in the body

Magnesium is a cofactor in more than 300 enzyme reactions, starting with every one that handles ATP. Magnesium contributes to a reduction of tiredness and fatigue, to normal energy-yielding metabolism, to normal muscle function, to the normal functioning of the nervous system, to normal protein synthesis, to normal psychological function, to electrolyte balance and to the maintenance of normal bones and teeth. It also has a role in the process of cell division.

Why bisglycinate rather than oxide

The form decides how much magnesium actually arrives and how the gut reacts. Magnesium oxide is cheap and dense in magnesium but poorly absorbed, and the unabsorbed part draws water into the bowel — which is why it loosens stools. Bisglycinate is magnesium chelated to two glycine molecules: it is absorbed as a small peptide-like complex rather than as a free mineral salt, so it does not depend on stomach acid and does not have the laxative effect. Glycine itself is a calming amino acid, which is part of why this form suits an evening dose.

Who tends to need more

Intakes below the reference level are common on diets built around refined grains, since magnesium sits in wholegrains, nuts, legumes and leafy greens. Needs rise with heavy sweating and regular training, with chronic stress, with alcohol, and with long-term use of proton-pump inhibitors or diuretics. Night cramps and eyelid twitching are the symptoms people usually notice first.

How to take magnesium bisglycinate

Two capsules a day with water, ideally in the evening — magnesium supports normal muscle and nervous-system function, and the glycine makes it a sensible end-of-day dose. It can be taken with or without food. Keep it an hour away from iron and zinc supplements, which compete for the same transporters.

Magnesium is also the mineral that converts vitamin D into its active form, so it belongs next to vitamin D3 2000 IU. If you want a single tablet with magnesium at a lower dose, see zinc + magnesium + B6 or magnesium citrate 200 mg.

Questions people ask

Bisglycinate or citrate?

Bisglycinate for sensitive digestion and evening use; citrate for a higher elemental dose per tablet and a mild effect on regularity.

Will it upset my stomach?

This is the form least likely to. The laxative effect belongs to oxide, sulphate and high-dose citrate.

Morning or evening?

Evening suits most people. Timing matters less than taking it every day. Full list in minerals.
