Whey Protein Isolate is considered to be the most nutritionally complete protein available to athletes and body builders. It’s easily absorbed for rapid conversion to muscle tissue. It is also low fat, low lactose and low in calories. It has a high biological value which means more of the protein is retained by the body to be converted to muscle. NutriSport's Whey Protein Isolate is no less than 84% protein and has added L-glutamine for more efficient recovery of muscle tissue. It undergoes no heat treatment; therefore the protein is un-denatured and retains its nutrients.
