Consumer Advice
Ferrous gluconate is a compound of gluconic acid and iron, used mainly to fortify foods with iron—such as breakfast cereals and infant foods—to help prevent iron-deficiency anaemia, and occasionally to preserve the colour of fruits and vegetables. Iron is an essential mineral and approved levels are safe. Note that large supplemental doses of iron can cause stomach upset, so it should be consumed at recommended amounts.
