The number most magnesium sellers leave off
"Magnesium glycinate 650mg" is the weight of the compound. The magnesium inside it is what your body uses, and it varies enormously by form: a true bisglycinate chelate is about 13 to 14% magnesium, a buffered glycinate 18 to 20%, and magnesium oxide 60% (but poorly absorbed and laxative). We publish both numbers on every product, and the %NRV is always against the elemental figure.
| Product | Compound per serving | Elemental magnesium | % NRV (375mg) |
|---|---|---|---|
| Magnesium Glycinate 650mg Capsules | 650mg per capsule | 85mg | 23% (2 capsules: 170mg, 45%) |
| Magnesium Glycinate Powder | 1g | 180 to 203mg | 48 to 54% |

| Magnesium & Potassium Citrate 1000mg Capsules | 333mg glycinate per capsule | 60mg (120mg per 2) | 16% (32% per 2) |

The 10 authorised magnesium claims, and what each one means
Magnesium holds more authorised claims than any other single mineral. A product needs at least 56mg of magnesium per daily serving (15% NRV) to carry them; every glycinate product here clears that. The bold wording is fixed by law; the explanation is ours.
| Authorised claim | What it means |
|---|---|
| Magnesium contributes to a reduction of tiredness and fatigue | Magnesium is needed to turn food into usable energy. Normal energy release, not a stimulant effect. |
| Magnesium contributes to electrolyte balance | Keeps sodium, potassium and calcium where they belong, inside and outside cells. |
| Magnesium contributes to normal energy-yielding metabolism | Hundreds of the enzymes that release energy from carbohydrate, fat and protein need magnesium. |
| Magnesium contributes to normal functioning of the nervous system | Nerve signals depend on ions moving across membranes; magnesium regulates that movement. |
| Magnesium contributes to normal muscle function | Calcium makes a muscle contract; magnesium lets it relax again. |
| Magnesium contributes to normal protein synthesis | Building new protein from amino acids is magnesium-dependent. |
| Magnesium contributes to normal psychological function | Thinking, concentrating, remembering. Not a mood, stress or sleep claim. |
| Magnesium contributes to the maintenance of normal bones | About 60% of the body's magnesium is in bone. |
| Magnesium contributes to the maintenance of normal teeth | Part of the mineral structure alongside calcium. |
| Magnesium has a role in the process of cell division | Copying DNA and dividing cells draw on magnesium. |
Not on the list: sleep, cramps, stress, anxiety and relaxation. Magnesium is widely sold for all of them and none is an authorised claim. Our product names describe the format; the claims on the page are the ten above.
Which form should you choose?
| If your priority is | Choose | Why |
|---|---|---|
| Digestive comfort on daily use | Magnesium Glycinate 650mg Capsules | Fully reacted chelate, no unreacted oxide, which is the part linked to loose stools |
| Most magnesium per gram | Magnesium Glycinate Powder | Buffered glycinate at 18 to 20%; about 2g for a full NRV |
| Lowest cost per serving | Glycinate Powder, larger sizes | No capsule step; price per gram falls sharply with pack size |
| No scales, no measuring | Capsules or tablets | Fixed serving; capsules have no fillers, tablets need binders |
| Magnesium and potassium together | Magnesium & Potassium Citrate 1000mg | 13 authorised claims in one capsule; read the potassium cautions on its page |
| Formulating or repacking | Bulk powder, 25kg to 100kg | 40 mesh, free-flowing, batch documentation supplied |

Magnesium L-threonate
Magnesium L-threonate is a newer form whose regulatory position in Great Britain differs from glycinate: it is authorised as a novel food only from one licensed source. We are reviewing our L-threonate line against that position. If you are buying it for resale or formulation, confirm the current status with the Food Standards Agency before you do.

Speak to your GP first if you
have reduced kidney function (impaired kidneys cannot clear excess magnesium), take antibiotics, bisphosphonates or thyroid medicine (leave two hours either side), or take any regular medication. Keep supplemental magnesium under 400mg a day. Loose stools mean the serving is too high. Not for under 18s, or during pregnancy or breastfeeding without advice.

How much elemental magnesium is in your products?
It depends on the form. The 650mg glycinate capsules provide 85mg (23% NRV); two capsules provide 170mg (45%). One gram of the glycinate powder provides 180 to 203mg (48 to 54%). The Magnesium and Potassium Citrate capsules provide 120mg magnesium per two capsules. Every product page states its own figure.
Why do two of your glycinate products have different percentages?
Different materials. The capsules use a fully reacted bisglycinate chelate at about 13 to 14% magnesium, with no oxide. The powder uses a buffered glycinate at 18 to 20% where some magnesium remains as oxide. Buffered gives more magnesium per gram; the true chelate is generally chosen for digestive comfort. We say which is which.
Is magnesium glycinate the same as bisglycinate?
The names are used interchangeably. Strictly, bisglycinate means one magnesium bound to two glycines, which is the fully reacted chelate. Compare products on the elemental figure, not the name.
Does magnesium help with sleep?
There is no authorised GB health claim for magnesium and sleep, so we make none. Magnesium contributes to normal psychological function and to normal functioning of the nervous system, which are the authorised claims and are narrower statements.
How much magnesium should I take a day?
The NHS reference intake is 270mg for women and 300mg for men from all sources. UK guidance is to keep supplemental magnesium under 400mg a day. High intakes cause loose stools, and oxide-containing forms do so at lower amounts.
Powder, capsules or tablets?
Powder is cheapest per gram and adjustable but needs milligram scales. Capsules are a fixed dose with no fillers. Tablets are a fixed dose and travel well but need binders. New to magnesium: start with capsules.
Can I take magnesium with medication or with kidney problems?
Speak to your GP first if you have reduced kidney function, because impaired kidneys cannot clear excess magnesium. Magnesium reduces absorption of tetracycline and quinolone antibiotics, bisphosphonates and thyroid medicine: leave two hours either side.
Do you supply magnesium wholesale?
Yes, across the whole range. Powder to 100kg, capsules and tablets in trade counts, white label and custom fills from our own encapsulation unit, with batch certificates of analysis. Use the contact page for a trade price.
