Ferrous glycinate is a chemical compound that combines iron in its ferrous (Fe²⁺) form with the amino acid glycine. It is often characterized by its relatively good stability and bioavailability. The combination with glycine helps increase the absorption and utilization of iron in the body. Ferrous glycinate is an important source of iron, an essential mineral that plays several critical roles. It is a key component of hemoglobin, which is responsible for carrying oxygen in the blood. Adequate iron levels are necessary for maintaining normal oxygen transport and energy production in the body. This compound is typically in a powder or crystalline form and is often used in nutritional supplements and fortified foods. In terms of its application in health and nutrition, ferrous glycinate is preferred by some over other forms of iron due to its lower potential for causing gastrointestinal side effects, such as constipation or stomach upset.
