1. How to Differentiate Between Whey Protein, Whey
Protein Isolate and Hydro Whey Protein
• Whey Concentrate: It is formed when liquid whey undergoes microfiltration. It
consists of 70-80% protein and is cheaper compared to the other types.
• Whey Isolate: It is formed when whey concentrate undergoes further processing.
It has 90% protein. It is costlier than concentrate. It has relatively lesser amounts
of fats and sugar in it than concentrate.
• Whey Hydrolysate: When the isolate is processed, then whey hydrolysate is
formed. This is the costliest type since it is highly processed and in pre-digested
form. It is easy for the body to absorb.
