Whey Protein Concentrate (WPC) is a highly nutritious, fast-absorbing dietary supplement derived from milk whey. A “100 g” package refers to the product weight, usually providing around 70 g to 80 g of pure protein to aid muscle recovery and growth.

What is WPC?
During the process of making cheese, milk separates into curds and whey. The liquid whey is then filtered and dried to form a concentrated powder.
Complete Protein: WPC is a complete protein, meaning it contains all nine essential amino acids your body needs.
BCAAs: It is rich in Branched-Chain Amino Acids (especially leucine) which are critical for building muscle and recovering from workouts.
WPC vs. Other Proteins
Protein Purity: WPC powders generally contain between 30% and 80% protein by weight. The remaining portion is made up of naturally occurring carbohydrates (lactose) and fats. [1, 2, 3]
Value: Because it requires less processing than Whey Protein Isolate (WPI), WPC is often more economical and typically features a richer, creamier taste. [1, 2]

A Note on 100 g Quantities
Purchasing a 100 g pouch or tub is an excellent way to test whether the flavor and consistency agree with your digestion. Since WPC contains lactose, individuals with lactose intolerance may experience stomach sensitivity and might prefer Isolate versions instead.
