Our verdicts
High Absorption Magnesium (Lysinate Glycinate)
A well-tolerated, clearly labeled chelated magnesium at a fair price, and a sensible first choice for people who found magnesium oxide or citrate hard on the stomach. Start with one 200 mg serving rather than the label's full 400 mg, and expect large tablets.
Full review
Magnesium (Glycinate)
This is the cleanest, most allergy-friendly magnesium glycinate you can easily buy, with unusually detailed testing disclosures and a formula that is kind to sensitive stomachs. You pay a premium for that, so budget buyers can get similar magnesium for less, but for people who react to fillers or other forms it is worth the money.
