Overview
This magnesium glycinate supplement delivers 500mg per serving in a chelated form, bound to glycine for gentler absorption than magnesium oxide. The 120-capsule bottle is gluten free, non-GMO and lab tested, aimed at sleep, muscle and heart support.
Glycinate is one of the better-tolerated forms of magnesium because it's bound to the amino acid glycine rather than sold as a cheaper salt like oxide, which is more likely to cause loose stools at higher doses. That tradeoff is why glycinate shows up often in magnesium supplements marketed around sleep and muscle recovery.
- 500mg magnesium glycinate per serving
- Chelated form for easier absorption
- 120 capsules per bottle
- Gluten free, non-GMO, lab tested
Who it's for
Suits people who've tried magnesium oxide and found it too harsh on digestion, or who want a chelated form for nightly use. Not the cheapest option per milligram if plain magnesium oxide is all that's wanted.

- Chelated glycinate form, gentler on digestion

Performance notes
Because magnesium is bound to glycine, it tends to absorb more gradually and cause less digestive upset than magnesium oxide, which is why glycinate is the form commonly recommended for sleep and muscle support use cases.
