You don’t need to be an avid supplement user or gym junkie to have heard about protein powder before. As one of the most popular supplements on the market, protein is one of the core building blocks of bone, muscle, and skin and is required in the production of hormones, enzymes, and other chemicals. When it comes to improving your health and fitness goals, supplementing with protein powder is a no-brainer as it’s an essential macronutrient that helps to build muscle, repair tissue, and assist in weight management. But, have you ever wondered exactly what the difference is between WPC and WPI, and which one is right for your goals?
