Lactose content is usually higher in concentrates than isolates, while sweeteners and other ingredients vary by product. People with significant kidney disease should individualize high-protein intake with their clinician.
Whey provides all essential amino acids and is rich in leucine, which stimulates muscle-protein synthesis. Its practical effect depends on total dietary protein, training, energy intake, dose, and the person's baseline intake.
