Magnesium FormMagnesium glycinate (chelate/bisglycinate)
Elemental Dose105 mg
Serving Size1 capsule
Life Extension Magnesium Glycinate delivers 105 mg of elemental magnesium per capsule via magnesium glycinate, a chelated form designed for high absorption and minimal GI upset. A single capsule per serving keeps the dosing simple.
Benefits: supports heart health, bone density, and nerve/muscle function—key wellness drivers in the magnesium-for-calm category.
Quality markers: Life Extension is a clinician-recognized brand with a solid reputation for ingredient purity and quality control. The product is non-GMO, gluten-free, and manufactured in the USA. Life Extension publishes Certificates of Analysis (CoA), a mark of third-party transparency, though not USP/NSF certified.
Fillers & additives: minimal excipients typical of capsule supplements; no magnesium oxide bulking reported.
Who it's for: health-conscious adults seeking a reliable, mid-potency glycinate supplement from a trusted brand. The 105 mg elemental dose sits at the lower-to-mid range for magnesium glycinate but is clinically meaningful for daily maintenance and calm support.
