What it is

Ferrous gluconate is a salt of gluconic acid, a substance naturally found in fruits and honey. It is produced commercially by reacting gluconic acid with iron salts. It appears as a white to yellowish-white powder or granules.

Why it's used

Manufacturers use ferrous gluconate to stabilize and maintain the color of foods, particularly in canned or jarred vegetables like olives, pickles, and peppers. It helps prevent discoloration that can occur during processing and storage. It is often found in preserved fruits and vegetables.

Health notes

Ferrous gluconate is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. It is a source of iron, an essential nutrient. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated ferrous gluconate and established an acceptable daily intake. Evidence does not suggest adverse health effects at typical intake levels.

Allergen info

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