Your protein supplements might be a waste of money. Studies show that people doing lots of endurance training need about 1.2 – 1.4g of protein per kg of body weight; and people who focus on strength training need about 1.4 – 1.8g per kg of body weight. There are no health or performance benefits from more than 2g of protein per kg of body weight. So, a normal healthy diet will provide enough protein for the average size person. Also, your body can’t absorb more than about 25g of protein in one go.
