The Active Ingredient Is: Iron (Ferrous Fumarate)

Iron is a mineral essential for normal function of the blood and oxygen transport in the body. Ferrous fumarate is a form used in supplements to provide elemental iron in a readily absorbed state.

In this product, iron sourced from ferrous fumarate supports the production of haemoglobin and the delivery of oxygen to tissues, contributing to energy metabolism and overall metabolic health.

What Does Iron (Ferrous Fumarate) Do?

Iron participates in haemoglobin formation and helps sustain normal energy production by supporting oxygen transport to tissues. This aligns with EFSA and NHS-accepted functions for iron in healthy blood and metabolism.

Its role is to help maintain normal physiological processes related to oxygen delivery and cellular energy, without implying treatment or disease effects.
