Whey Protein Isolates (WPI) are processed to remove fat and lactose, and as a result, WPI powders are typically over 90% protein by dry weight. Like WPC, WPI are mild and slightly milky in taste. Whey Protein Hydrolysates (WPH) are whey proteins that are predigested and partially hydrolyzed for the purpose of easier metabolizing.
For bodybuilders, whey protein provides amino acids used to aid in muscle recovery. [15] Whey protein is derived from the process of making cheese from milk. There are three types of whey protein: whey concentrate, whey isolate, and whey hydrolysate. Whey concentrate is 29–89% protein by weight whereas whey isolate is 90%+ protein by weight.
A meta-study found that in the first few weeks of strength training with untrained individuals, changes in lean body mass and muscle strength during the initial weeks of strength training are not influenced by the protein supplementation, but after the first few weeks, protein supplementation “may promote muscle hypertrophy and enhance gains in muscle strength in both untrained and trained ...
