Providing all of the essential amino acids, which are the building blocks of healthy muscles, nails, skin and other connective tissue, whey protein not only is almost completely devoid of cholesterol but aids in the removal of “bad” cholesterol from the body. Whey protein has the ideal combination of amino acids to help improve body composition and enhance athletic performance.

Whey protein is an excellent source of the essential amino acid, leucine. Leucine is important for athletes as it plays a key role in promoting muscle protein synthesis and muscle growth. Whey protein is a soluble, easy to digest protein and is efficiently absorbed into the body.

It is often referred to as a ""fast"" protein for its ability to quickly provide nourishment to muscles. The body requires more energy to digest protein than other foods (thermic effect) and as a result you burn more calories after a protein meal. Whey protein is an excellent protein choice for cancer patients as it is very easy to digest and very gentle to the system.

Whey protein may be added to a wide variety of foods and beverages to increase the protein content without affecting taste. Healthy nutrition practices have been shown to play a role in helping to manage, and possibly prevent, the onset of type-2 diabetes. Whey protein, a high quality, high biological value protein, is a good choice for diabetics who need to carefully manage food intake.

A recent study in Europe compared whey protein to casein, the primary protein in milk. They found that older men who consumed whey protein showed greater protein synthesis, or growth, which helped limit muscle loss over time.
