Whey Isolate is a premium form of whey protein, offers the highest protein content per serve and minimal fats and carbs. It is remarkably low in lactose (99% lactose free), making it an excellent choice for individuals with lactose intolerance who struggle with protein digestion.
On the other hand, Lean Protein is a blend of Whey Isolate and whey concentrate, providing slightly less protein per serving and a higher lactose content compared to Isolate. However, it offers a more favourable price point.
