Magnesium Glycinate 400mg with Quercetin — 120ct × 3

Magnesium Glycinate 400mg with added Quercetin — a chelated bisglycinate formula designed for sleep, relaxation, and muscle health. Each capsule delivers 400mg elemental magnesium as a fully chelated glycinate, requiring 1 capsule per serving. The 120-count, 3-pack format provides 120 servings total at $0.16 per serving (or $0.14 with Subscribe & Save).

No third-party certification (USP/NSF/ConsumerLab) stated on the listing. Fillers appear minimal based on standard capsule formulation, though full ingredient transparency is limited. The addition of Quercetin (a flavonoid antioxidant) is marketed for additional wellness support, though magnesium glycinate alone is the core active.

Best suited for those seeking a high single-dose elemental magnesium in an easy-to-swallow capsule format. Newer Amazon-brand entry with moderate review velocity and community discussion; lacks the established clinical reputation of practitioner-grade competitors.
