Protein is an important macronutrient that plays a major role in the entire body. It makes hormones and enzymes, while also helping keep your muscles, bones, blood, and hair and nails healthy.
Protein helps build, repair and maintain tissues, as well as boost the immune system, increase fat burning and lower the risk for diabetes.
