Whey Protein Isolate (WPI) is a highly filtered, ultra-pure form of whey protein that contains 90% or more protein by weight, with nearly all fats, carbs, and lactose removed. A 500 g package refers to the total weight of the product, typically yielding about 15 to 20 servings, depending on your preferred scoop size. [1, 2, 3]

Key Characteristics
High Protein Concentration: Delivers around 25g to 27g of pure protein per serving. [1, 2, 3]
Fast Absorption: Because it digests rapidly, it is ideal for rapid post-workout muscle repair and recovery. [1, 2, 3]
Lactose & Fat Light: The advanced micro-filtration process removes almost all lactose and fat, making it an excellent option for individuals with lactose intolerance or those on low-carb/keto diets
Rich in Amino Acids: It contains a high concentration of Branched-Chain Amino Acids (BCAAs), especially leucine, which is vital for building and maintaining muscle mass.

Common Uses
Muscle Building & Recovery: Consumed before or immediately after workouts to stimulate muscle protein synthesis.
Weight Management: Helps curb appetite and preserve lean muscle mass during weight loss.
Flexible Flavoring: Often sold as an unflavoured powder so you can mix it directly into smoothies, oats, or baked goods without altering the taste profile. [1, 2, 3]
