Why people keep reordering it
- Highly absorbable forms
- Chelated forms your body takes up, instead of oxide that mostly passes through.
- Calm and recovery
- Supports muscle relaxation, sleep quality and everyday stress resilience.
- Gentle on digestion
- Formulated to skip the laxative effect of cheaper magnesium.
Best suited to: gets stomach upset from magnesium oxide or citrate, wants magnesium for muscle cramps or restlessness, takes magnesium daily long term.
What the research supports
This is magnesium bis-glycinate, a form where magnesium is bound to two glycine molecules, delivering 200 mg of elemental magnesium per capsule. Magnesium in this chelated form supports normal muscle function, nerve signaling, and bone maintenance without the laxative punch of cheaper magnesium salts. It's built for daily, ongoing use rather than an occasional flush.
At 200 mg elemental per capsule, this lands in the middle of the 150 to 400 mg range typically used in trials for sleep quality, muscle cramping, and general repletion, and most people take one to two capsules depending on dietary intake.
- Muscle cramp relief (evidence: moderate, from rct)
- Supplementing elemental magnesium in the 200 to 400 mg range has shown modest benefit for muscle cramping in some trials, though results are inconsistent across populations.
- Sleep quality (evidence: mixed, from rct, small human trial)
- Magnesium supplementation has shown improved subjective sleep quality in some small trials, particularly in older adults or those with low baseline magnesium, but not consistently across all studies.
- Bowel tolerance versus other magnesium salts (evidence: moderate, from rct, comparative human trial)
- Human studies comparing magnesium glycinate to oxide or citrate generally show less gastrointestinal disturbance at equivalent elemental doses.

Is it right for you
Worth it if
- Gets stomach upset from magnesium oxide or citrate
- Bis-glycinate is bound to glycine rather than existing as a loose salt, so it's absorbed more gently and causes far less bowel loosening.
- Wants magnesium for muscle cramps or restlessness
- 200 mg elemental per capsule is enough to meaningfully move someone from a marginal intake toward the amounts used in muscle and sleep research.
- Takes magnesium daily long term
- The gentler absorption profile makes it realistic to take consistently without dose-limiting diarrhea.
Look elsewhere if
- Specifically wants magnesium for constipation
- Magnesium citrate or oxide. Bisglycinate is absorbed rather than left sitting in the gut, which is the entire point of the form and the opposite of what moves things along.
What to expect
Nothing dramatic or immediate. If you're low in magnesium, sleep and muscle tension can feel noticeably better within a couple of weeks of consistent daily use, but if your levels are already fine you likely won't notice anything at all.
How it compares
- Compared with magnesium oxide
- Bis-glycinate is absorbed far more efficiently and doesn't rely on osmotic pull through the gut, so it works without the urgent bathroom trips oxide is known for. The tradeoff: Oxide is cheaper per milligram and is actually the better pick if someone wants magnesium specifically for its laxative effect.
