A capsule cannot be split, so this is the nearest dose you can actually take. It is shown as a caveat and is deliberately not used in ranking — rounding up changes the dose delivered as well as the price.
  • One comparison dose is 1.33 capsules, and capsules cannot be split. In practice you would take 2 capsules, which delivers 300 rather than 200 mg.
  • Elemental magnesium as printed on the Supplement Facts panel, not derived from compound weight.

Ordered by price, lowest first, and labeled so you can see what each link earns us. Commission is never an input to that ordering — if the cheapest retailer pays us nothing, that is still the one we send you to. Today no link on this page earns us anything: we have applied to affiliate programs but none is live, so every Buy button below is a plain retailer link.

Verification — Tier C: Manufacturer-disclosed only

The only testing information available comes from the manufacturer or a lab it commissioned. This may well be accurate; it is simply not independent.

  • The brand states the product is third-party tested but has not published results we could verify.

No test reports located for this product.

Not established: Heavy-metal testing, Label-accuracy testing, Vegan status.
Absence of data is not evidence that a product is clean. It means nobody has published a result we could find.

Label read from: Core Med Science — Magnesium Bisglycinate 60 ct - Supplement Facts panel · checked 2026-08-31 · not human-verified
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.
