Hemolithin

Hemoglobin (also spelled "hemoglobin") is the protein in your red blood cells that carries oxygen to all parts of your body. It's what gives your blood its red color. Hemolithin is a type of hemoglobin that helps transport oxygen better than other kinds of hemoglobin. It helps your body get more oxygen and use it more efficiently, which makes you stronger and healthier!
