Overview
Metagenics packs its magnesium into a glycinate form, the chelated version formulated for easier absorption than plain magnesium oxide. The 120 tablet bottle is vegetarian, non-GMO and gluten free, positioned for sleep, stress and muscle support.
Magnesium comes in several chelated forms, and glycinate is generally considered gentler on the stomach than magnesium oxide, which is likely why Metagenics frames this tablet around sleep and muscle relaxation rather than just bone health. The vegetarian formulation broadens who can take it.
- 100 mg magnesium glycinate per tablet
- 120 tablets per bottle
- Vegetarian, non-GMO, gluten free
- Positioned for sleep and muscle support
Who it's for
Suits people looking for a gentler, well absorbed magnesium tablet for sleep or muscle relaxation, including vegetarians who need that formulation. It may not suit those who prefer capsules, powders or a higher elemental magnesium dose per tablet.
