Magnesium Glycinate

Labels here are unusually misleading: compound weight is often printed instead of elemental magnesium. Several products sold as glycinate are blended with oxide.

Common questions

What is the cheapest magnesium per dose?

Every magnesium we track, priced per 200 mg of elemental magnesium rather than per capsule or per bottle, grouped by which salt it is. The salt you choose moves the price far more than the brand does.

Magnesium glycinate vs citrate: what is the difference?

What each form costs per 200 mg of elemental magnesium, how many capsules that takes, and what the Supplement Facts panels actually say. What we do not compare is absorption, because we do not measure it.

Is magnesium glycinate actually all glycinate?

Some products sold as magnesium glycinate name a second, cheaper salt on their own Supplement Facts panel. Here is what each panel we have read actually says, product by product.

About these numbers

What “per dose” means here — 200mg elemental magnesium

200 mg of elemental magnesium is roughly half the adult RDA and is the most common single-serving strength, which makes it a convenient common denominator. It is a unit of comparison, not a recommended intake.

Labels often print the weight of the whole magnesium-glycinate compound, of which only a fraction is magnesium. We compare on elemental magnesium, which is the figure the Supplement Facts panel is required to give.

How reliable is this data?

Public beta — real data, mostly not yet human-verified. These products, prices and certification listings were collected from NSF's Certified for Sport database, the LGC Informed database, iHerb and BulkSupplements. Every claim links to the source it came from, and you are welcome to check any of them.

Servings per container are derived from net weight rather than read off the label, except where a note on the product says otherwise.
Most source records have not been checked by a person. The ones that have say so.
Amazon and Walmart are not included, so “cheapest” means cheapest among the retailers we track.
Prices go stale. Each one shows when it was last checked, and says so when it is older than the retailer allows us to cache it.

How we make money

Right now, nothing on this page earns us anything. We have applied to affiliate programs but none is live yet, so every “Buy” button is a plain retailer link. When that changes, each link will say what it earns us, on the link itself.

Commission will play no part in what we list, how it ranks, or which link we send you to — the Buy button points at the lowest price we have recorded even when that retailer pays us nothing.
