There are two vital windows to take protein so that you build muscle the most efficient. Right after your workout when you are in an anabolic window, and right before bed. This is where Casein protein comes in. Casein protein is a gelatinous protein that takes 8-hours to digest. When taken before bed, it will use all 8 hours while you sleep. It is proven that the muscle building process happens at night. Your body repairs the muscles and having ample amounts of nutrients is key. Taking Casein before bed will give your body these nutrients and keep the muscle building process primed for development.

How it works: The slow digesting protein gets released over an 8-hour period so your muscles are constantly being fed.
