Whey protein isolate 90%, often referred to as WPI 90, is a high-quality dietary supplement derived from whey, the liquid portion of milk left over during cheese production. It is highly refined to remove most of the fats, lactose, and other non-protein components, resulting in a protein powder that is predominantly protein, typically containing over 90% protein content by weight. Whey protein isolate is recognized for its rapid digestion and absorption, making it a popular choice among athletes, fitness enthusiasts, and individuals looking to increase their daily protein intake. It is used in various nutritional products, including protein shakes, bars, and dietary supplements, due to its effectiveness in supporting muscle recovery, growth, and overall protein needs, while being virtually free from lactose and fats, making it easier on the digestive system for many individuals.
