Whey Protein Powder
Whey protein is fast absorbing and is rich in essential amino acids (EAAs), which are crucial for muscle protein synthesis (i.e. muscle building). This makes whey protein an ideal choice for post-workout recovery, especially for hard-training athletes who are looking to maximize muscle mass and strength.
Now you may have noticed that whey protein comes in various forms, including whey concentrate, isolate and hydrolysate. You may have even wondered what the difference is between the three. Let’s take a closer look at what sets each type of protein apart.
