How much protein is in Whey Protein Powder?

Protein content in whey protein powders can vary greatly from brand to brand and depending on the type of whey protein used. Additional additives can also reduce the total protein content. These include flavors, sweeteners, preservatives and agents to improve mixing.

Whey protein comes in three forms, whey concentrate, whey isolate and hydrolysate. Whey concentrate is the least processed form and contains more impurities meaning you should expect it to contain around 80% protein content. Isolates generally offer much better value for money and have been more highly refined to produce around a 90% pure protein. Hydrolysates are an isolate which has been further processed a pre-digested with enzymes. Hydrolysates are generally around 94% or higher in protein content.
