Whey Protein Isolate is considered to be the most nutritionally complete protein available to athletes & body builders. It’s easily absorbed for rapid conversion to muscle tissue. It is also low fat, low lactose & 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. Nutri Sport's Whey Protein Isolate is no less than 84% protein & has added L-glutamine for more efficient recovery of muscle tissue. It undergoes no heat treatment; therefore the protein is un-denatured & retains its nutrients.
