Whey Isolate Protein Powder

What is Whey Isolate?

Whey isolate is a high-quality, fast-digesting protein supplement that contains a higher percentage of pure protein compared to other whey forms. It is processed to remove most fats, carbohydrates, and lactose, making it ideal for muscle recovery, lean muscle growth, and low-calorie diets. Whey isolate is especially favored by athletes, bodybuilders, and those with lactose sensitivity.
