Casein
 

Casein protein is a favorite product among bodybuilders when you need to get more slow-digested protein and stop muscle breakdown while sleeping. To make casein even more beneficial, mix it with flaxseed oil in your shake as it helps avoid cholesterol problems, reduces the risk of liver disease and decreases the blood pressure.

By eating 28 grams of casein protein powder and one tablespoon of flaxseed oil, you’ll absorb 221 calories, 20 grams of protein, two grams of fat and three grams of carbs.
