Our take

Each Thorne capsule holds 120 mg of magnesium, and a bottle has 90 capsules. The Amazon listing calls it a chelated magnesium glycinate, which means the magnesium is bound to glycine, a small amino acid.

For this brand set against another, see Thorne vs Doctor's Best glycinate.

Pick it for one-capsule servings and a 90-capsule bottle from a brand with an NSF listing. Prefer a sport mark? Core Med Science Magnesium Bisglycinate carries NSF Certified for Sport (see below).
