Whey protein is considered a complete protein and contains all 9 essential amino acids. It is also low in lactose content. It can help you build muscle, support muscular recovery, and maintain muscle when training to lose fat. It is of high-quality, highly bio-available, and fast-digesting.

Whey protein isolate powders are absorbed rapidly into the blood stream and deliver essential nutrients to the muscle cells for quick recovery from your gruelling workouts.
