Whey protein shakes are probably the most widely used sports supplement on this list. They are a clean and simple way to reach your daily protein intake quota. If you come in shy of the amount of protein you need per day (generally 0.7 grams per pound of body weight) you risk falling into catabolism. Protein helps your muscles repair and grow after exercise.
Who Should Take It?
Anyone with a goal of strength and muscle building is going to need a high protein intake to repair the deliberate muscle tissue damage sustained though training. Whey protein makes it easier to get to your set amount, without having to consume huge amounts of food.
