Summary:
- Whey protein comes in different forms: isolate, concentrate, and casein. Each type has slightly different properties and benefits.
- Whey isolate is the most purified form, containing a higher percentage of protein with less fat and carbohydrates. It is quickly absorbed by the body.
- Whey concentrate contains a bit more fat and carbohydrates than isolate, but is still a high-quality protein source that is moderately absorbed.
- Casein protein is absorbed more slowly by the body, providing a steady supply of amino acids over a longer period of time.
