Ultimate Iron Glycinate
Iron bis-glycinate is a well-studied, 100% fully-reacted form of iron. The amino acid glycine is actually one of the two starting materials the body uses to synthesize hemoglobin. therefore, Ultimate Iron Glycinate contributes two key factors. This form of iron has higher bioavailability, lower toxicity, less food reactivity, less food interactions and has a longer shelf life than any other common form of iron.
