Whey Protein (WPC) Vs. Whey Isolate (WPI) - the main difference is, that Isolate Protein is more refined and contains less dairy. Whey protein isolate has been isolated to ensure each serve has the maximum amount of protein with the least amount of carbohydrates, fats and additives. This purity makes Whey Protein Isolate the fastest absorbing and most bio available protein source.
Whey Protein Isolate helps recovery (due to its high yield of BCAA’s), strength and muscle levels as well as strengthening the immune system.
Due to its refinement (less milky counterparts, fats and carbohydrates), WPI mixes very well in water but is generally less flavoursome and a little watery compared to WPC. However, if you are someone who suffers from general digestive issues, a protein source that is low in lactose, WPI is the protein for you.
