Whey protein isolate is the highest yield of protein currently available. Because of its properties, whey protein isolate is the easiest form of protein to absorb into your muscles. With its high concentration of pure whey and BCAAs, whey protein isolate is widely regarded as the best protein you can eat.
Some benefits of whey protein isolate over other protein types are:
Highest value in providing branched-chain amino acids (BCAA), the building blocks of your muscles. Whey protein contains all 9 essential amino acids.
Contains high amounts of Leucine; an amino acid that aids in muscle growth and helps with speedy recovery.
Most pure and concentrated form of whey protein available.
Contains very little (if any) fat and lactose.
