Muscle Milk is designed for anyone looking to support recovery for those with an active lifestyle.

Protein provides amino acids that help support muscle repair and recovery after exercise or physical activity.

After a workout, many people look for fluids to help rehydrate and protein to help support muscle recovery. Carbohydrates can also help refuel the body and restore glycogen after longer or more intense workouts.

Protein is the major nutrient associated with supporting muscle recovery after workouts or strenuous activity.

Rehydrating and refueling as soon as you can after exercise helps support recovery.
