Containing 80% of milk, casein is a nutritive protein source with all essential and non-essential amino acids, phosphorus & calcium caseniate. The true strength of this protein is its slow-digesting ability. It works by steadily & constantly releasing amino acids into the body for 7 hours. With this constant flow of aminos in the body, the muscles stay fed and nourished and there is no muscle breakdown. Thus, it is recommended to be consumed at night before bedtime as during this time the body is not able to get nutrition and muscles get robbed of the nutrition. This is how casein also contributes to the maintenance of the muscle mass by feeding the muscles with nutrition. To know more to buy casein protein supplement at lower price, visit www.getfitness.in .
