It produces its powder products and pre-blends of ready-to-drink products at a 150,000-square-foot (14,000 m2) manufacturing facility. Its products are endorsed by running back Adrian Peterson and by college swimming coach Mike Bottom.

PepsiCo Inc. PEP has successfully completed the buyout of the CytoSport business from Hormel Foods Corporation HRL to overcome the effects of the fall in carbonated soft drinks ('CSD') category sales. The company paid about $465 million for CytoSport, which comprises of Muscle Milk and Evolve brands.

Muscle Milk, made by CytoSport, is a hugely popular protein supplement company that's well known for their lactose free, high fructose corn syrup-free, trans fat-free, high protein products.

If you're a super active individual who needs extra nutrients to sustain your training, Muscle Milk could be a suitable option to support muscle growth.
