Whey Protein: A Pure, Natural Protein from Cow Milk

Whey protein is a pure, natural source of protein that is a rich source of essential amino acids. The components of whey protein fight disease, are easily digestible, and are essential to the body.

Many body builders and athletes use whey protein for muscle development and recovery. Whey protein has also historically been used by those with suppressed or abnormal immune systems or degenerative diseases to increase the body's antioxidant levels.

According to the Whey Protein Institute, whey protein isolate is one of the best sources of the essential amino acids required in the daily diet. These essential amino acids are the building blocks of healthy muscles, skin, nails and other body tissue. Therefore, whey protein can be used effectively for many purposes, including physical performance and cardiovascular health.

The Whey Protein Institute cites whey protein as the "gold standard" of protein for serious athletes. Research studies also suggest that whey protein aids the body in building and sustaining strong muscles.

Whey protein is a naturally complete protein, containing all of the essential amino acids required by the body. It contains high levels of branched chain amino acids, which are metabolized directly into muscle tissue and used first by the body during periods of physical activity. Since whey protein is easy to digest, it provides efficient nourishment to the body's muscles. Given these characteristics, whey protein is ideal for improving the body's composition and enhancing athletic performance.

Whey protein also contains high levels of the essential amino acid leucine, which promotes muscle protein synthesis and muscle growth. Whey protein contains significantly more leucine than other protein supplements, and it contains about 50% more leucine than soy protein isolate.

Whey protein also promotes a healthy immune system. Whey protein provides an excellent source of glutathione, an important antioxidant which is depleted by physical exercise and training. Glutathione must be constantly replenished to keep the immune system functioning properly.

Given the benefits of using whey protein, it is an excellent supplement for cyclists. Whey protein will keep a cyclist's body replenished and healthy, promoting physical endurance and stamina. With this supplement, a cyclist can keep his or her muscles working efficiently and can optimize his or her athletic performance.

Whey protein is available in most health food stores and many supermarket and drugstore health sections. They are usually flavored and can be mixed with water or milk and consumed as a drink or shake.
