Top features
Magnesium FormMagnesium bisglycinate chelate
Elemental Dose90 mg per 3 capsules
Serving Size3 capsules
Nature Made Magnesium Glycinate 300mg delivers 90 mg elemental magnesium per 3 capsules as a chelated bisglycinate form, designed for absorption and gentle GI tolerance. This 2-pack (60 servings total) targets sleep, calm, muscle relaxation, and stress support.
Key features:
- USP-verified supplement (recognized quality standard)
- No magnesium oxide filler — pure chelated form
- Moderate elemental dose per serving (90 mg is below the ~200–300 mg clinical range, requiring 3 capsules)
- Established mass-market brand with strong Amazon review velocity (4.5★, tens of thousands of reviews)
- Vegetarian capsules
- Limited third-party testing disclosure beyond USP label claim
Who it's for: Budget-conscious shoppers seeking a recognizable, trusted brand with a gentle magnesium form; not ideal for those needing a high single-dose or practitioner-grade purity.
Caveats: Three capsules per serving may feel burdensome for daily use; cost per serving ($0.26) sits mid-market—higher than bulk NOW Foods or Doctor's Best value lines.
