FAQ
Worth the cost?
Magtein is significantly pricier than glycinate. Use it specifically for cognitive or memory goals; pick glycinate for general magnesium.
Elemental magnesium dose?
2g Magtein delivers ~144mg elemental magnesium. Small relative to other forms; the brain-targeting is the selling point.
Evidence in humans?
Small trials show improvements in working memory and sleep quality. Larger studies are still limited.
