Whey Protein is the most popular protein used today. It is actually derived from cheese and concentrated to form a protein powder supplement. Bodybuilding athletes require a high intake of protein, between 1 and 2 grams per pound of body weight per day. The only way to get such a high intake is to use protein supplements. Protein has long been proven to feed muscles and help them recovery and grow. Without protein supplementation you will not grow and develop as you cannot recovery or provide the additional food required for muscle growth. Whey protein typically reaches full blood protein synthesis in around 40 minutes so the total digestion range is from 30 minutes to around an hour. The most common in take is recommended as soon as you wake, post workout and before bed. Protein can also be used between meals.
