Optimum Nutrition is recognized for providing the athletic world with exceptional dietary supplements. Optimum Nutrition Gold Standard 100% Casein is just one of their outstanding products. Read on to learn how this supplement can help you with your bodybuilding goals.

Ingredients Based on Quality

Optimum Nutrition Gold Standard 100% Casein is made with 24 grams micellar casein protein per serving. Casein is a slow-digesting protein that is found in milk (80% of the protein in milk is casein).

It’s also made with five grams of branched-chain amino acids (fundamental in increasing protein synthesis and increasing workout intensity), nearly five grams of glutamine (supports recovery) and also contains 40% of the recommended daily allowance of calcium. Each serving contains only 140 calories, one gram of fiber, 1.5 grams of fat and eight grams of carbohydrates.

The Benefits of Casein Protein

The major benefit of consuming casein protein comes from its slow digestive properties. On average, casein takes five hours to fully digest. Casein is sensitive to stomach acid, and as a result, it thickens during the digestion process. This thickening allows casein to form a gel that releases a steady stream of amino acids to help you build muscle. This makes casein protein perfect to take before going to bed or between meals.

Another benefit of using casein protein is greater gains in lean mass. A Texas study took 36 bodybuilding athletes and divided these men into two groups. One took a combination of whey and casein protein, while the other group supplemented their diet with whey, BCAA’s and glutamine. The group taking the whey and casein supplement made greater gains in lean mass than those who supplemented their diet with whey, BCAA’s and glutamine.

Supplementing with casein protein also leads to greater strength gains. One study pitted the effects of supplementing with whey protein and casein protein and found that the participants who used casein protein got twice as strong as those who supplemented with whey protein.

Increased fat loss is yet another benefit of supplementing your diet with casein protein. When taken before going to bed, casein has been shown to increase metabolism during sleep. Casein protein supplementation also results in higher satiety levels (up to 33% higher).

In addition to this, the high calcium content of this supplement will help strengthen your bones and teeth.

A Range of Flavors to Choose From

Optimum Nutrition Casein comes in a variety of flavors. If you’re a chocolate lover, you’re in luck. This supplement comes in chocolate supreme, chocolate peanut butter, chocolate cake batter and mint chocolate chip.

If you like more fruity flavors you can go with strawberry cream or banana cream.

A Good Mixer

This dietary supplement mixes well with water, juice or milk. You can mix it in a shaker or a blender and they’ll both give you good results. You can also add a scoop of this protein to your favorite yogurt for a healthy snack.

For people with an allergy to casein, side effects may be experienced. These side effects include stomach pain, nausea, bloating, diarrhea and vomiting. It’s important to note that these symptoms are not experienced by the majority of people who consume casein protein.
