Know your Whey Protein - Whey Protein Concentrate vs Whey Protein Isolate
Posted: Feb 22, 2019
Whey protein is one of the best sources of protein that quickly and adequately provides sufficient protein and other nutrients to aid in muscle recovery and growth. However, there are multiple brands and varieties of whey protein, and it can be challenging to figure out the difference between these forms of proteins, what they do, and which one should you choose.
Here, we will find out the difference between the two most common forms of whey protein supplements available in the market: whey protein concentrate and whey protein isolate. The differences between these two forms of whey proteins are how they are processed, and the nutritional differences between them.
Whey Protein Concentrate
Liquid whey is a by-product of cheese making process. This liquid is filtered and then dried to make whey protein concentrate powder, of which up to 80% is protein and the remaining consists of small quantities of fats and carbohydrates..It has numerous benefits as it is a reliable source of protein, has very low carbohydrate and fat content and is a good source of amino acids. It is best used before or after working out. It is lower in pure protein than whey protein isolate. It is not suitable for lactose intolerant person as it contains high lactose content. Whey Protein Isolate
Pure whey protein isolate supplements contain high percentages of whey protein isolate. It is extracted from further filtration of the whey concentrate. It also has smaller quantities of carbohydrates and fats than whey concentrate. It delivers a greater amount of protein per serving and is quickly absorbed in the digestive tract. It means that your muscles get protein quickly, making them less prone to damage while growing and developing at the most effective rate.
Since whey protein isolate is derived from added levels of filtration, this means that the isolate is more labor-intensive and therefore more expensive. Due to the extra filtration, it loses some of the nutrients found in the 100% whey protein supplement but gives more protein per serving. It is also suitable for those who are lactose intolerant because of the very small quantities of lactose in it.
How to Choose Between Whey Protein Concentrate and Whey Protein Isolate?
Both the Whey Protein Concentrate and the Whey Protein Isolate are good sources of protein. They are fortified with BCAAs (branched-chain amino acids) and other essential nutrients. The concentrate has up to 80% protein, while the isolate has between 90-95% of pure protein.
For those who count calories and want to reduce their weight, opting for the isolate is better since it has fewer carbohydrates and fats. For those who need to build muscle mass, the added calories, carbohydrates and fats in the concentrate are more appropriate. Deciding to buy whey protein powder depends entirely on the goals of the trainer or the exerciser, as neither of the products is inherently better than the other but serve different nutritional purposes well. Whey protein isolate is more expensive than whey protein concentrate. Before buying any protein powder consult with your trainer or dietician which is more helpful to select the right one.
