The details

Optimum Nutrition Gold Standard Casein powder is a wonderful product by the very famous brand, Optimum Nutrition. This product mainly focuses on reducing the rate of digestion in your body and supporting a better muscle recovery process.


This powder is rich in Aminogen. Aminogen is a blend of various enzymes that promotes better absorption of all kinds of nutrients. Aminogen and other enzymes present in this powder support slow yet quality digestions of all the nutrients so your body can stay fuller for longer. When you are mostly full, you do not crave food as much. This helps to achieve your weight goals and you can focus on a good diet.


This powder contains Aminogen, as mentioned above. Every scoop has 24 grams of Casein, 3 grams of carbs, and 0.5 grams of fats. Moreover, this powder also has milk, soy, artificial colors, and flavors. There aren’t many nutritional ingredients in this powder. This powder lacks essential vitamins and minerals.


Vanilla and Chocolate flavors are very famous. The powder mixes well in water and creates a smooth and creamy texture. However, all the flavors are on the sweet side. If you do not have a sweet tooth, this product might not be for you.

Value for money

Casein is way expensive and valuable than other kinds of proteins. This is why this product is a little pricier. However, if you compare this product with its competitors, you will find this powder a little expensive.

Final verdict

Optimum Nutrition has never produced a disappointing product. Casein Protein powder has all the good qualities and benefits you need to improve your digestion. However, if you can’t stomach soy, milk, or artificial flavors, this product is not for you.
