Whey Protein Isolate

Protein is the most important nutrient needed to grow lean muscle. The protein levels naturally present in your diet can only give you a certain level of results, even when trying to eat a lot of protein-rich foods. Whey protein isolate can be the answer to getting the protein intake you need to see some serious changes to your body. In its purest form, whey isolate powder can accelerate your fat loss and muscle development process.

Whey Protein Isolate (WPI) is one of the highest quality protein powders available, and is very low in carbohydrates, fat and lactose (the sugar in milk). It is rapidly absorbed by the body while providing the highest value of BCAAs. Whey protein Isolate offers all of the benefits of regular whey protein while having low, or zero lactose content in some cases. Whey protein isolate can be beneficial to people who suffer from lactose intolerance but would prefer to stay with a whey protein. 

What are the benefits of consuming whey protein isolate?

Whey Protein Isolate is the purest form of whey protein. It is a dietary supplement that’s created by separating the components of milk that are less-suited for muscle gain. 

One of the best things about whey protein isolate, is its formula of ingredients and levels of BCAAs. Your body requires several of these nutrients to repair and then grow muscles after strenuous workouts. Isolate protein is the best source of those BCAAs.

Whey protein in general is also easy to digest and can be low in fat. Because whey protein isolate powder is the purest form of this protein, it makes it extremely easy to be digested immediately after consumption, promoting rapid muscle fiber growth. 

Straining muscles during workouts results in heavy muscle damage. Whey protein isolate enhances the repairing of that damage, allowing for more growth. Whey Protein Isolate can help in the generation of lean tissues that can add to muscle mass and accelerate the growth of your muscles. Consumption of Whey Protein Isolate post-workout is great for increasing muscle size and vigour.

What is the difference between whey protein concentrate and whey protein isolate?

The protein content in whey protein concentrate is about 80% while the content of protein in whey protein isolate is 90%. Not only does whey protein isolate powder contain more protein but it also contains less fat, carbohydrates and cholesterol. Whey protein isolate is processed through micro-fibre filters that trap the cholesterol and fat to keep them from being added to the final product. A performance-enhancing version of whey protein isolate is also made that contains 3g of added L-Glutamine to further preserve muscle tissue.

Regardless of the differences, whey protein, in general, is a great source of protein for muscle-building as it contains the essential branched-chain amino acids that you need to put on size and possibly shed fat. You can consume whey before or after a workout to increase the level of amino acids available for muscle protein synthesis. If you suffer from lactose intolerance, whey protein isolate is probably a more safe version of whey protein.

What to consider when buying whey protein isolate powder?
