Several important factors are involved in the absorption of iron into the body, some of which can either promote or slow down the absorption process. Here's a closer look at how iron is absorbed and what factors can affect it.
What affects iron absorption?
Several important factors are involved in the absorption of iron into the body, some of which can either promote or slow down the absorption process. Here's a closer look at how iron is absorbed and what factors can affect it.
Iron absorption in the body primarily occurs in the small intestine. Iron can come from food sources or supplements. Iron is best absorbed from heme iron found in animal products like meat and fish. Non-heme iron from plant sources is absorbed slightly less efficiently, but absorption can be enhanced with vitamin C. Certain factors such as calcium, tea, and coffee can inhibit iron absorption, while meat, fish, and vitamin C promote it. A varied and balanced diet is important to optimize iron absorption.
