Elemental Dose360mg
Serving Size3 capsules

Nature's Bounty Calm Magnesium Glycinate delivers 360mg elemental magnesium per serving as a chelated glycinate complex in a vegetarian capsule format (3 capsules per serving, 90 capsules / 30 servings per bottle). The product is formulated to support calm mood, heart health, muscle function, and stress relief — core benefits of the magnesium glycinate category. Nature's Bounty (owned by Nestle Health Science) is a recognized mass-market wellness brand with 50 years of heritage and USP verification on many of their formulations, though this specific listing does not prominently display third-party testing certifications. The formula is non-GMO, gluten-free, and vegetarian-friendly, with no disclosed magnesium oxide filler. At ~$0.17 per capsule ($14.95 regular / $14.20 Subscribe & Save), the per-serving cost (~$0.50) sits mid-range for the category. Community feedback is generally positive but notes that three capsules per serving is a meaningful daily commitment. No major quality red flags in available reviews, though some users report larger-than-expected capsule size.
