E579 Ferrous gluconate

What is Ferrous gluconate (E579)?

E579, known as ferrous gluconate, is a compound that combines gluconic acid with iron. It serves primarily as an iron supplement and food additive, functioning as a color enhancer and fortifier in various food products. Ferrous gluconate is often used in fortified cereals, bread, and nutritional supplements to increase the iron content and support dietary needs.

Why do I have an intolerance?

Intolerance to ferrous gluconate can arise from individual sensitivities to iron or food additives. Some individuals may experience gastrointestinal issues, such as nausea or constipation, when consuming products fortified with ferrous gluconate. Additionally, those with conditions that affect iron metabolism or those prone to iron overload should exercise caution with this additive.

What can I do about it?

To manage intolerance to E579, it’s essential to read ingredient labels and avoid products that contain ferrous gluconate. Focusing on whole foods and unfortified products can help reduce exposure. For individuals needing iron, consider incorporating natural sources such as legumes, nuts, seeds, and leafy greens into your diet, which can provide essential nutrients without the risk of intolerance symptoms.
