Magnesium Bisglycinate
Thorne is the industry gold standard for purity and bioavailability, utilizing a fully chelated bisglycinate form that minimizes the laxative effect common in cheaper alternatives. It is one of the few brands with NSF Certified for Sport status, ensuring no banned substances or hidden contaminants.
Ingredients & Purity
Contains 200mg of Magnesium Bisglycinate per scoop. Uses monk fruit for sweetness and avoids maltodextrin or artificial colors.
Scientific Evidence
Magnesium bisglycinate is clinically proven to have superior absorption compared to oxide or citrate. Thorne's manufacturing facility is NSF and TGA certified.
Brand Transparency
Thorne provides comprehensive labeling and is the only supplement brand to partner with the Mayo Clinic for clinical research.
Value Assessment
At roughly $0.80 per serving, it is a premium-priced product, but the high bioavailability means less waste through excretion.
Why Not Alternatives?
Unlike competitors like Nature's Bounty or Solgar, Thorne eliminates stearates and unnecessary fillers. While brands like Doctor's Best use similar chelates, Thorne's rigorous NSF certification and superior solubility in water make it more reliable for sensitive GI tracts.
