The Active Ingredient Is: Iron (Ferrous Bisglycinate Chelate)

Iron is an essential mineral involved in normal red blood cell activity and energy metabolism. This formulation uses Ferrous Bisglycinate Chelate, a gentle, highly bioavailable iron form designed to support iron utilisation.

This formula also has included cofactors such as Vitamin C, Vitamin A, riboflavin, biotin, copper, Betaine HCl and lipase, which support iron absorption and metabolism as described in research on iron utilisation.

What Does Iron Do?

Iron plays a role in normal oxygen transport and red blood cell formation to support daily energy needs. Studies indicate that cofactors such as Vitamin C enhance non-heme iron absorption and that copper, riboflavin and Vitamin A are involved in iron metabolism and utilisation.

These mechanisms work together with digestive and metabolic support to help maintain normal iron status and function in the body. Dr. Hallberg of the University of Copenhagen found that cofactors can influence iron absorption and utilisation.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
