Whey Protein

Whey protein is the water-soluble portion of milk separated during cheese-making and commonly sold as concentrate, isolate, or hydrolyzed powder. It’s typically mixed with water or milk for shakes, blended into smoothies, or added to recipes like oatmeal and baked goods; people track whey protein to log protein, calories, and macronutrients, support their dietary planning, and account for milk-derived ingredients or allergies.
