Interesting Fact
Iron Makes Red Blood Possible
Iron is a key part of hemoglobin, the protein in red blood cells that carries oxygen from your lungs to the rest of your body. Without enough iron, your body can’t make healthy red blood cells, which is why iron is included in many supplements. Leafy greens, beans, and red meats are natural sources of iron in everyday diets.
