What it is

Ferrous gluconate is an iron salt of gluconic acid. It is made by reacting iron with gluconic acid, which is produced by the fermentation of glucose. It appears as a yellowish-gray powder or granules.

Why it's used

Manufacturers add ferrous gluconate to foods as a source of iron, a nutrient. It is also used to maintain color in some products, such as olives, by preventing oxidation. It can be found in canned fruits and vegetables, baked goods, and some beverages.

Health notes

In the US, ferrous gluconate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement or for color retention. It is a common form of iron used in dietary supplements and fortified foods. JECFA has evaluated ferrous gluconate and established an acceptable daily intake. While iron is essential, excessive intake can be harmful; however, this is unlikely from typical food consumption.

Allergen info

Ferrous gluconate is not derived from any of the nine FDA major allergens. It does not contain gluten.
