How It Works
How It Works
Iron bisglycinate chelation bonds elemental iron to glycine amino acids, creating a stable complex your intestinal tract recognizes and absorbs efficiently. This bypasses the irritation caused by conventional iron salts, while delivering iron directly to support hemoglobin formation and oxygen transport.
Who It's For
Adults with diagnosed iron deficiency, particularly menstruating women aged 12-49 who experience the highest deficiency rates. Athletes and active individuals who need reliable iron support without digestive interference.
Who It's Not For
Those with iron overload conditions or hemochromatosis. Always test iron levels before supplementing.
