The Active Ingredient Is: Iron (Ferrous Bisglycinate Chelate)

Iron is a mineral essential for several normal bodily functions. The ferrous bisglycinate chelate form provides iron bound to amino acids, which aids its stability and absorption in the gut.

This form is supplied as Ferrochel ferrous bisglycinate chelate and is recognised for being gentle on the stomach compared with some other iron salts.

What Does Iron Do?

Iron contributes to the formation of red blood cells and to normal oxygen transport in the body. Scientific understanding supports these roles alongside iron’s involvement in energy production and general metabolic function, as recognised by EFSA and NHS guidance.

Research indicates iron bisglycinate offers improved absorption with fewer gastrointestinal side effects compared with other iron forms, a finding attributed to its chelated structure. Dr. Milman of University of Copenhagen highlights the iron chelate’s bioavailability and tolerability in adults.
