Overview
This magnesium glycinate supplement delivers 400mg of chelated magnesium per serving in a 270-tablet bottle, sized by the listing as a 4+ month supply aimed at sleep, relaxation and muscle support.
Glycinate is a chelated form of magnesium, framed by the listing as gentler on digestion and higher absorption than less bioavailable forms like magnesium oxide. At 270 tablets, the bottle is built for sustained daily use rather than a short trial size.
- 400mg chelated magnesium glycinate per serving
- 270 tablets, a 4+ month supply
- Vegan
- Positioned as gentle on digestion
Who it's for
Fits people wanting a long-running daily magnesium supplement for sleep, relaxation or muscle support in a vegan tablet form. Less suited to anyone wanting a fast-dissolving powder or a magnesium form chosen specifically for a laxative effect, which chelated forms are not typically used for.
Strengths and trade-offs
Drawn from this product's published specifications.
- 400mg chelated magnesium glycinate per serving
- 270 tablets, a 4+ month supply
- Vegan tablet form
- Framed as gentle on digestion versus other magnesium forms
- Large tablet count means a bigger bottle to store upfront
- Unflavored tablet only, no powder or gummy option here
Performance notes
Magnesium glycinate is chelated, meaning the mineral is bound to glycine, which the listing associates with gentler digestion than non-chelated forms. The 270-tablet count sets this up as a multi-month routine rather than a short supplement course.
