Key Features at a Glance
What Is Magnesium Glycinate 650mg?
Magnesium Glycinate (also called Magnesium Bisglycinate — the same compound, CAS 14783-68-7) is the chelated form of magnesium — the mineral is bound to two glycine amino acid molecules, which protects it during digestion and significantly improves absorption compared to inorganic forms like magnesium oxide. Each capsule provides 650mg of chelated magnesium bisglycinate — delivering 85mg of elemental magnesium, Supplier COA verified.
The recommended serving is 1–2 capsules daily. A 2-capsule serving provides 170mg elemental magnesium — 45% of the 375mg daily NRV — well within the NHS safe upper limit of 400mg from supplements daily. Many people find 2 capsules daily the optimal approach, particularly when taking in the evening for sleep and muscle relaxation support.
All capsules are produced in-house at our facility in Southend-on-Sea, Essex — which holds a 5 Star Food Hygiene Rating from Southend-on-Sea City Council. Big Idea Services Ltd, Co. No. 11645389. 160,000+ verified sales since 2016. Food supplement — not a medicine.

Frequently Asked Questions
How much elemental magnesium is in each capsule?
Each 650mg capsule provides 85mg elemental magnesium — Supplier COA verified. That is 23% of the 375mg daily NRV. A 2-capsule serving provides 170mg elemental magnesium — 45% NRV.
Can I take 2 capsules per day?
Yes — 2 capsules daily is the recommended serving. This provides 170mg elemental magnesium (45% NRV) — well within the NHS safe upper limit of 400mg daily from supplements. Do not exceed 2 capsules daily without GP advice.
Why is magnesium glycinate better than oxide?
Magnesium oxide has approximately 4% bioavailability. Magnesium bisglycinate is chelated — bound to glycine — which significantly improves absorption and avoids the laxative effect common with oxide and citrate. It is the preferred form for daily supplementation.
Will it cause a laxative effect?
No — unlike magnesium oxide and citrate at higher doses, bisglycinate does not typically cause a laxative effect at standard doses. The chelated form absorbs through different intestinal pathways.
When is the best time to take it?
Evening is preferred by most people — magnesium's muscle-relaxing and nervous system-calming effects make it well suited to a night-time routine. Can be taken with or without food.
Is it vegan?
Yes — vegan HPMC capsule shell, no gelatin, no animal-derived ingredients. No fillers. Suitable for vegans and vegetarians.
Do you sell magnesium glycinate wholesale?
Yes. Charge Products (Big Idea Services Ltd, Co. No. 11645389) supplies magnesium glycinate capsules wholesale UK. Contact chargeproducts.co.uk/pages/contact for trade pricing and MOQ.
