Ferrous Bisglycinate

Ferrous bisglycinate is a form of iron, a mineral essential for human health. It is made by combining iron with the amino acid glycine. This chelated form of iron is often used in supplements and fortified foods.

Manufacturers add ferrous bisglycinate to foods and supplements to increase their iron content. Iron is a vital nutrient, and this form is chosen for its bioavailability and reduced tendency to cause digestive upset compared to other iron salts. It is commonly found in meal replacement supplements, protein drinks, and baked goods.

In the U.S., ferrous bisglycinate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated iron compounds, and the European Food Safety Authority (EFSA) has also assessed iron as a nutrient. Iron is crucial for oxygen transport in the blood, and deficiency can lead to anemia. However, excessive iron intake can be harmful, and the body has limited mechanisms to excrete it.
