Whey Protein for Your Muscle Building and Recovery

Last updated on August 24, 2021.

Whey protein is a concentrated source of protein in the liquid portion of milk separated from the curds during the cheesemaking process. It is rich in easily digestible branched-chain amino acids (BCAAs), which are readily available for muscle protein synthesis and building of new muscles  after resistance and endurance exercise particularly in athletes or active individuals. Whey protein may also reduce appetite and improve body composition by decreasing fat mass and increasing lean mass.

Whey protein is available in 3 forms:

  • Whey protein concentrates

Produced by extracting protein from milk using heat and acid or enzymes, it typically contains 60-80% whey protein and 20-40% fats and carbohydrates.

  • Whey protein isolates

With an additional filtering process, it typically contains 90-95% whey protein and minimal amounts of fats and carbohydrates.

  • Whey protein hydrolysates

It is a whey protein in the form of amino acids produced by further heating with acid or enzymes, easily digestible and quickly absorbed by the body.
