Whey protein can be obtained as an isolate from whey, a by-product of cheese that is obtained from cow’s milk. This form of protein is naturally complete which means that it contains all amino acids that are essential for the body, and it is required to be consumed as a part of the daily diet. These essential amino acids form the building blocks for fit and healthy body tissues, muscles, nails and skin. The ideal combination of amino acids present in whey protein helps to enhance athletic performance as well as improve body composition.

The whey protein isolate contains about 92%-97% of protein content. This dairy by-product contains low level of cholesterol and fat and hence it is a perfect low-fat diet supplement.

Whey protein is popular among bodybuilders and weightlifters as it contains ample amount of protein required by the body’s muscles to support such heavy physical sports. Whey protein helps in the sustenance of such strenuous work-outs without wearing away; hence, it is very useful during resistance training.

Whey protein is also useful for serious athletes who aim to build a strong and lean physique. Leucine, an essential amino acid, required for muscle growth and muscle protein synthesis can be found in whey protein. It is a very rich source of BCAA (Branched Chain Amino Acids) which get directly metabolized into the various muscle tissues present in the body. This replenishes the required levels and helps in the rebuilding and repairing of lean, strong and healthy muscle tissues.

Whey protein is an excellent energy booster. Larger muscle areas which require excess of protein are provided by whey protein isolate. Since the calorie intake is low, it does not cause stomach upset. Hence, this supplement is suitable for weight loss and controlled diets.

Whey protein supplements are suitable for all age groups. A variety of flavors are available for people to choose from. They can be bought from fitness centres and even at their local health stores which house such health supplements suitable for workouts. It strengthens the immunity of the body and helps to prevent cancer.

Since whey protein is easily soluble, it is easily digested and absorbed efficiently in to the body. It provides very quick nourishment to the body muscles, and hence, it is referred to as "fast" protein. Whey protein is a source of glutathione, an anti-oxidant which helps in building a healthy immune system.

Whey protein contains two hormones, glucagon-like peptide-1 (GLP-1) and cholecystokinin (CCK). These two bioactive components are appetite suppressants and hence, whey protein supplements are commonly recommended during weight loss programs.

Whey protein is also high recommended for patients with cardiovascular complications. It is also suitable for cancer patients who undergo chemotherapy and radiation treatments and have difficulty in providing the nutritional requirements of the body due to appetite loss, nausea and fatigue. Whey protein is rich in cysteine, another essential amino acid that boosts the immune system by raising the level of glutathione levels.

Whey protein powder can be added to many foods and beverages without really affecting the taste.
