How It Works

Our bodies need elements that are naturally found in the foods we eat, but sometimes we need to supplement our diets with extra elements. One of the elements our body needs is iron. Iron is commonly found in beans, spinach and in cereals such as Total. We need iron to help us absorb oxygen into our blood.
