Functional Advantages & Bioavailability
As a bisglycinate chelate, this magnesium powder offers distinct formulation and physiological advantages for product developers. The amino acid chelation protects the magnesium ion through the acidic gastric environment, delivering it more efficiently to intestinal absorption sites. This translates to higher net bioavailability and lower effective doses compared to traditional inorganic salts. The glycine carrier itself contributes functional value, acting as an inhibitory neurotransmitter that supports central nervous system calmness—an added benefit in sleep and stress-targeted formulations. The compound demonstrates excellent compression characteristics for tableting and blends uniformly with hydrophilic and lipophilic excipients alike.
