Whey Protein

Whey protein maximizes your workouts

Eating just 20 grams (1) of whey protein right after you exercise may help you get more of what you want from your workout. Lean muscle. A toned body. Improved body composition.

Whey protein, a natural high-quality protein derived from milk, is a rich source of branched-chain amino acids (BCAAs), including leucine. Research shows leucine independently stimulates muscle protein synthesis (2,3).

Consuming whey protein in combination with resistance exercise can increase the rate at which the body makes lean muscle and may help improve body composition (4,5). What's more, combining protein intake and resistance exercise yields better results than either of the two alone (6) or combining a carbohydrate-only beverage with resistance training (7).

Just 20g of whey protein following resistance exercise has been shown to stimulate protein synthesis (8). One nutrition bar or beverage contains 8g to 30g. Start making whey protein a part of your workout routine today.
