What it is
Ferrous gluconate is an iron salt of gluconic acid. It is produced by reacting gluconic acid (derived from glucose) with a source of iron, such as iron carbonate. It appears as a yellowish-gray powder or granules.
Why it's used
Manufacturers add ferrous gluconate primarily as a nutrient to fortify foods with iron. It is also used as a colorant, particularly in olives and pickles, to help maintain a dark, uniform color. It is commonly found in canned olives, pickles, and relishes.
Health notes
In the U.S., ferrous gluconate is Generally Recognized As Safe (GRAS) by the FDA for use as a nutrient and color additive. Iron is an essential nutrient, and ferrous gluconate is a common source used in food fortification. JECFA has evaluated ferrous gluconate and established an acceptable daily intake. While iron is vital, excessive iron intake can be harmful, and the body tightly regulates iron absorption.
