Optimum Nutrition has a long reputation in the supplement industry for making quality products. Their casein protein is no different. This powder contains 24 grams of protein, 1 gram of total fat and 3 grams of carbohydrates per serving. At 120 calories per serving, this is a fairly lean protein. Being that this is casein protein, it is slower digesting. Many people like to take this protein in between meals or right before bed. Taking right before bed is advantageous as it allows your body to absorb the protein while you sleep which will aid in muscle recovery. A lot of people like to pair casein protein with whey protein. It is recommended to use the whey protein after your workout and then use the casein before sleep. Another advantage to using this protein is that it will help you to feel fuller for a longer period of time. Casein products thicken in the stomach and are acid sensitive. Gold Standard Casein provides 5 grams of branched-chain amino acids (BCAA) which your muscles will absorb for up to eight hours. This casein protein is actually micellar casein which means its more bioactive then regular casein. Combining it with other enzymes, this will ensure that this casein product will absorb better than other casein proteins on the market.

Gold Standard casein has a great taste and mixes very easily with water or milk. I prefer to mix mine with almond milk as this gives it a nice and milkshake like consistency. The flavor is a bit on the sweeter side so take that into consideration when deciding on your protein powder.
