Whey protein concentrate is the most common form of whey protein powder. It undergoes minimal processing, retaining a higher percentage of lactose, fat, and bioactive compounds. WPC typically contains around 70-80% protein by weight and offers a cost-effective option for individuals looking to supplement their protein intake.
- Whey Protein Isolate (WPI)
Whey protein isolate is a more refined form of whey protein, with a higher protein content (around 90-95% protein by weight) and lower levels of lactose and fat. WPI is well-suited for individuals with lactose intolerance or those seeking a purer protein source.
- Whey Protein Hydrolysate (WPH)
Whey Protein hydrolysate, also known as hydrolyzed whey protein, is produced by further processing whey protein isolate or concentrate. It undergoes enzymatic hydrolysis, breaking down the protein into smaller peptides and amino acids. This pre-digested form of whey protein is rapidly absorbed by the body, making it an excellent option for individuals with digestive issues or those seeking quick protein absorption.
- Health Benefits of Whey Protein Powders
