What is whey protein isolate?
Whey protein and whey protein isolate are derived from the milk proteins of cows or goats during the cheese manufacturing process. Whey was originally used as an animal feed for many years. Veterinarians noticed the animals became healthier when they were fed whey, which led to research into the benefits of whey. In 1992, a process was developed that extracts the pure amino acids from milk proteins leaving behind all the sugar (lactose), fat, and cholesterol. What the nutritional scientists came up with is the purest, cleanest, most biologically available (most easily absorbed) source of protein in history. Whey protein isolate is the richest source of essential amino acids and branched-chain amino acids your body needs for growth and energy.
