Magnesium Bisglycinate Powder
Thorne's Magnesium Bisglycinate is the gold standard for purity and bioavailability, utilizing a fully chelated form that minimizes digestive upset while maximizing absorption for muscle relaxation and sleep support. It carries the NSF Certified for Sport designation, ensuring it is free from over 200 banned substances and contaminants.
Quality & Materials
Contains 200mg of elemental magnesium per scoop as magnesium bisglycinate chelate. Uses monk fruit as a sweetener instead of sugar or artificial sweeteners.
Evidence & Testing
Magnesium bisglycinate is clinically shown to cross the blood-brain barrier more effectively than oxide. Thorne is the only supplement brand to collaborate with Mayo Clinic on clinical research.
Brand Transparency
Thorne performs four rounds of testing on every batch. They are an A-rated manufacturer by the TGA (Australia's regulatory body, stricter than the FDA).
Value Assessment
At roughly $0.70 per serving, it is more expensive than grocery store brands but offers significantly higher bioavailability and third-party safety certifications.
Why Not Alternatives?
Unlike many competitors (e.g., Nature's Bounty or generic brands), Thorne uses 100% magnesium bisglycinate rather than 'buffered' blends that sneak in cheaper, less absorbable magnesium oxide. Their powder form avoids the bulky fillers and binders found in large 200mg tablets.
