In many whey products, it is nonexistent due to the type of processing employed. The best whey products will contain less than 1% lactoferrin-and more like 0.5%-of this rare but important micro-fraction. Some companies are now able to add in a specific subfraction to get a truly “designer” muscle milk protein. One company is also working on making an isolate that will have higher levels of the beneficial subfraction alpha-lactalbumin, and lower levels of the more allergenic and less nutritive subfraction Beta-lactoglobulin. “High alpha-lac” whey isolates would be potentially superior to what is currently on the market in large scale production.
