GHK Fe capsule is an iron supplement used to treat or prevent low blood levels of iron (such as those caused by anemia or pregnancy). Iron is an important mineral that the body needs to produce red blood cells and keep you in good health. GHK Fe capsule contains carbonyl iron, which is a form of iron that is easily absorbed by the body. It also contains folic acid, which is a vitamin that helps the body use iron. GHK Fe capsule is usually taken once or twice a day, with or without food. The dosage is based on your individual needs.
