Whey protein has become popular among the bodybuilding and fitness enthusiast fraternity because it proffers a complete spectrum of both essential and branched chain amino acids. Usually, whey proteins are marketed in three-forms: whey isolate, whey concentrate or whey hydrolysate. All three-forms are unique from each other in terms of protein content.

Whey concentrate consists of both carbs and fats while whey isolate contains carbs and fats in a negligible quantity. That’s why isolate is considered as the purest form of whey protein.

Whey isolate contains all indispensable amino acids and BCAA in a copious amount. Among all three BCAA’s (leucine, isoleucine and valine), leucine is found in isolate in a plentiful quantity which promotes the protein synthesis in muscles.

Whey isolate supplements are usually consumed after an intense exercise session to prevent tissue damage which in turn, enhances the performance. Some studies revealed that isolate protein an hour before and after exercise may promote muscle hypertrophy and strength. Whey isolate is found to be more effective in enhancing blood amino acids and protein synthesis than other regular protein supplements which are available in the market. This is possible because of high bioavailability and absorption of all essential amino acids which are necessary for the protein synthesis. Additionally, whey is a copious source of L-cysteine amino acids and leucine. Both are rate-limiting amino acids and most important for the development of the body. L-cysteine is the precursor of glutathione which is a potent antioxidant.

Therefore, whey isolate supplementation aids in the increase of glutathione level and protects the body against any oxidative damage. In athletes, glutathione need increases with the intensity of workout thus resulting in the production of more oxygen free radicals. Due to which antioxidant demand in the body increases in-order to neutralise these free radicals reducing muscle fatigue and exhaustion. Athletes who are at their leaning phase, isolate is the best option for them as it contains a negligible amount of lactose and fat.

Whey protein isolate is not restricted to athletes or fitness enthusiasts but can be used by people who are on a weight loss diet. One of the best thing about the whey protein isolate is that it can also be consumed by a mild lactose intolerant individual as it is almost lactose-free.
