Protein is found throughout the bodyâin muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.
Endurance athletes such as marathoners need about 50% more protein than a sedentary person, says sports dietitian Josephine Conolly-Schoonen, MS, RD, on Medscape Today. Body Builders might need twice as much protein as a sedentary person. But it's important to remember than most Americans, including athletes, get plenty of protein in their regular diet, and do not need protein supplements.
