Whey Protein: Beneficial or Harmful? Whey protein is one of the most widely consumed nutritional supplements globally. From athletes and fitness enthusiasts to elderly individuals with sarcopenia, its use spans multiple demographics. But the question remains: Is whey protein truly beneficial — or potentially harmful? Let’s examine the science. What Is Whey Protein? Whey protein is derived from milk during cheese production. When milk coagulates, it separates into: Curds (solid fraction → cheese) Whey (liquid fraction → protein-rich) Whey is considered a complete protein because it contains all nine essential amino acids. It is especially rich in leucine, which stimulates muscle protein synthesis via activation of the mTOR pathway. There are three common forms: Whey Concentrate (WPC) – 70–80% protein, contains some lactose and fat Whey Isolate (WPI) – ≥90% protein, minimal lactose Whey Hydrolysate (WPH) – Pre-digested, faster absorption Health Benefits of Whey Pr...
