Iron supplements are a type of dietary supplement that can help individuals increase their iron intake. Iron is an essential mineral that is necessary for the production of hemoglobin, a protein found in red blood cells that carries oxygen throughout the body. Iron supplements are often recommended for individuals who are not getting enough iron through their diet or who have a medical condition that affects their ability to absorb iron. They come in various forms such as tablets, capsules, and liquid, and can be purchased over-the-counter or with a prescription from a healthcare provider.
