Whey protein concentrate is a dairy protein powder that keeps more of milk's natural fats and carbohydrates. This gives it a mild, creamy taste.
People take it after exercise to help muscles recover and grow. Taking it within a few hours of a workout works best.
It contains lactose, so it suits those who digest dairy comfortably. If you are lactose-sensitive, it may upset your stomach. Mix it with water or milk and drink it after a workout or as a meal supplement.
