Ferrous gluconate is a type of iron supplement commonly used to treat or prevent iron deficiency anemia. It is a compound formed from iron and gluconic acid, making it easier for the body to absorb compared to some other iron supplements. This supplement is often recommended for individuals who have low iron levels due to dietary deficiencies, pregnancy, or certain medical conditions. It can help increase the amount of iron in the body, which is essential for producing hemoglobin, the protein in red blood cells that carries oxygen.
