Whey protein isolate is a type of whey powder with very little lactose and fat and is one of the purest and most efficacious forms of protein. Whey protein is quickly absorbed into the body, and is especially important for athletes or those adopting a workout routine.

Here are the health benefits:

1. Muscle growth – Filled with all the essential amino acids that are directly metabolized by the muscles, it helps prevent degradation of muscles.

2. Weight loss – Protein is beneficial for weight loss in two ways: it requires more energy to digest and it slows the absorption of glucose into the blood. It also suppresses the appetite.

3. Immune system – Whey protein isolate increases the levels of glutathione, an antioxidant that reduces the number of free radicals that are important for the immune system.
