Hepcidin

Hepcidin is a small protein produced by the liver that helps regulate how the body manages iron, which is essential for making red blood cells and supporting various bodily functions. It controls iron levels by signaling the intestines to absorb less iron from food and informing the organs to release less iron from storage. When the body has enough iron or is inflamed, hepcidin levels increase to reduce iron in the bloodstream, preventing excess. Conversely, low hepcidin levels allow more iron to enter the blood, supporting needs like red blood cell production. Proper regulation of hepcidin is vital for maintaining healthy iron balance.
