Thanks to its lower fat content, the protein isolate has no fat to slow down the digestion process. This means that whey protein isolate is digested faster than concentrate if you're looking for quick post-workout nutrition. In general, the processing steps used in the production of whey isolate result in a higher protein content and a lower fat and carbohydrate content per serving. The next step in obtaining a higher type of whey protein is to ultrafilter the whey protein concentrate.
That said, those who are limiting their intake of fat, carbohydrates or lactose may prefer whey isolate, since it contains less of these three components than whey concentrate. The liquid sweet whey that remains after the separation of the casein goes through a process called microfiltration. Immediately after the training session, the subjects consumed 25 grams of hydrolyzed whey, 25 grams of whey isolate, or a protein-free placebo. If you want to increase your endurance and feel the effects of your high-intensity workouts, the choice is obviously a hydrolyzed whey protein isolate.
Another study shows that powdered proteins based on dairy products (such as whey) can increase IGF-1 levels in the body and promote muscle cell replication and proliferation. If you're looking for a non-dairy protein powder, research suggests that pea protein produces results similar to whey. In addition to their nutritional differences, there are cost differences between these two types of whey. Whey isolate may be a good option for those who are carefully limiting their intake of fat, carbohydrates, or lactose, although this form of whey is usually more expensive.
If you've ever opened a container of your favorite yogurt and noticed a clear liquid floating on top, that clear liquid is the peptides in whey. During the six-week study, the group that consumed whey protein had higher levels of growth hormone and developed more muscle mass than the control group that didn't receive protein powder. The reason is that whey is a complete protein and one of the most natural protein sources available on earth. While it's known that whey protein is the best when it comes to muscle recovery and development, less well known are the differences between each type of whey protein that exists.
A study published in the Journal of Science in Medicine and Sports found that subjects who consumed hydrolyzed whey isolate after training experienced better recovery and performance, soon after an intense session of muscle damage, compared to those who consumed whey isolate. A whey hydrolysate is advantageous for attenuating muscle damage and quickly replenishing glycogen, so you will enjoy a complete recovery much faster than with other types of whey.
