Product Overview

I recently had the opportunity to try Optimum Nutritions Gold Standard 100 Micellar Casein Protein Powder. This product is a great choice for anyone looking to get more protein into their diet without compromising on taste or quality. The powder comes in two sizes 2 and 4lb tubs and nine delicious flavors, so theres something for everyone.

To start off, I tried the Creamy Vanilla flavor. It had a great taste and was not overly sweet, which was perfect for me. The texture was also smooth and creamy, so it didnt feel grainy in my mouth like some other protein powders can.

The product contains 24g of high quality slow digesting casein protein per serving, with 3g of carbs, 1g of sugar, and 1g of fat. This makes it an ideal choice for those looking to support muscle recovery overnight or between meals. Its also great for weight management goals as it helps you feel fuller for longer periods of time.

From a value for money perspective, I think this product is well worth its price tag. The 2lb tub contains 32 servings, while the 4lb tub contains 64 servings both offer good value for money considering the quality of the ingredients used. Additionally, I found that the powder blended easily when mixed with liquid or non dairy milk of your choice no clumps or lumps here!

I would highly recommend Optimum Nutrition s Gold Standard 100 Micellar Casein Protein Powder to anyone who is looking for a high quality protein supplement that tastes great and mixes easily with liquids or non dairy milk options. It has all the benefits of casein protein such as aiding muscle recovery overnight or between meals as well as helping with satiety and weight management goals without sacrificing taste or quality. Plus, it offers great value for money considering how many servings you get per tub!
