Micro Ingredients Magnesium Glycinate delivers 1,000mg of chelated magnesium glycinate per 2-capsule serving, combined with vitamin C for antioxidant support. Each bottle contains 300 capsules (150 servings), providing a substantial supply at an accessible price point.

Form & Purity: Pure chelated magnesium glycinate with no magnesium oxide filler — a key advantage in the glycinate category. Formulated with active ingredients only; free from fillers, soy, dairy, gluten, shellfish, peanuts, and tree nuts.

Third-party Testing: Product passes Micro Ingredients' 3rd-party lab testing for safety, purity, and potency — though specific certifications (USP, NSF, ConsumerLab) are not explicitly stated on the listing.

Elemental Dose: 500mg elemental magnesium per capsule (1,000mg per 2-capsule serving) — a clinically meaningful dose for sleep, calm, and muscle relaxation.

Community Reception: Micro Ingredients has earned steady recognition in r/Supplements and r/Magnesium forums; users appreciate the glycinate form and absence of oxide filler. Complaints are minimal — primarily around large capsule size and the need for 2 capsules per dose.

Best for: Sleep-focused shoppers seeking high-dose, pure glycinate with no fillers at mid-market pricing.
