Overview
This magnesium glycinate capsule combines a 400mg chelated magnesium dose with quercetin in a 120-count bottle, marketed toward sleep, relaxation, and muscle health for both women and men.
Chelated magnesium glycinate is generally chosen over other magnesium forms for being easier on digestion, and pairing it with quercetin is a less common combination the label ties to sleep, stress, and immune support. No brand name beyond the generic 'Magnesium' listing and no seller description or reviews accompany this product, so the ingredient pairing is the main thing to go on.
- 400mg magnesium glycinate per serving
- 120 capsules per bottle
- Quercetin included
- Gluten, dairy, and soy free
Who it's for
Suits adults looking for a magnesium supplement geared toward sleep and stress relief who don't mind a two-ingredient formula with quercetin included. Less suited to someone who wants a single-ingredient magnesium product without extra compounds mixed in.
