The Active Ingredient Is: Iron (Ferrous Bisglycinate Chelate)

Iron is a crucial mineral involved in making haemoglobin and carrying oxygen around your body. The Ferrochel chelated form is meant to be gentler on the stomach and helps normal iron status and red blood cell development when paired with the right cofactors.

This formula also includes vitamin C and active B vitamins to support the overall nutrient setup for iron utilisation and healthy blood building.

What Does Iron Do?

Iron helps with normal blood formation and supports oxygen transport around the body. Vitamin C helps iron absorption, and active B vitamins support erythropoiesis, which aligns with EFSA-style function claims for how nutrients work together in healthy blood formation.

The combination of Iron with cofactors helps support normal physiological processes related to iron status and red blood cell development, while the chelated form is described as gentler on the stomach than some other iron forms.
