What is Optimum Nutrition 100% Casein Gold Standard Protein Powder?

Although there are several types of protein that you can supplement with, one of the best is just now getting the attention it deserves. While most people will immediately hail whey isolate or concentrate, casein protein is becoming the newest “must have” supplement. Casein protein is the slowest to digest of all the protein types. This is good news for your muscles as this means amino acids are circulating for hours after one serving.

If you want to experience the best that casein protein has to offer, there’s only one trusted brand to go with: Optimum Nutrition 100% Casein Gold Standard Protein Powder.

ON’s Casein continues to boost the reputation of a long standing company. Using ON’s Casein as a part of your supplementation program, you’ll be supporting your goals of weight loss and muscle building.

What are the benefits of using Optimum Nutrition 100% Casein Gold Standard Protein Powder?

Optimum Nutrition 100% Casein Gold Standard Protein Powder is the highest quality casein protein on the market. Studies have been demonstrating the amazing effectiveness of casein protein for a number of fitness-based benefits including the following:

Protein synthesis



With the steady stream of amino acids over hours, the body is able to engage in a higher level of protein synthesis. This creates the perfect anabolic environment for muscle growth.

Protects Muscle Tissue



Amino acids that are circulating in the muscle tissue help to protect from breakfast or a catabolic environment.

Suppresses Appetite



Once ingested, casein protein forms a slow digesting gel in the stomach. This gel releases amino acids over the course of hours, helping to avoid unnecessary cravings. (1)

Who should be using Optimum Nutrition 100% Casein Gold Standard Protein Powder?

Optimum Nutrition 100% Casein Gold Standard Protein Powder is an ideal supplement to use for a variety of people including those who have been in the fitness industry for decades or those just starting out. It provides you with 24 grams of the purest quality protein, which is ideal for muscle growth, recovery, and performance. See real change with ON’s Casein.

Directions
Consume approximately 1 gram of protein per pound of body weight per day through a combination of high protein foods and supplements. For best results, consume your daily protein allotment over several small meals spread evenly throughout the day.

Shaker: Using a shaker cup is the easiest way and most convenient way to mix up a consistently great casein shake every time. Just add one heaping scoop of Gold Standard 100% Casein™ to your shaker cup and them pour in 10-12 oz of your preferred beverage. Cover and shake for 25-30 seconds. Tip: Adjust the intensity of your Hold Standard 100% Casein™ by varying the amount of liquid that you use to prepare it. For a bolder flavor with slightly more body and sweetness, mix one heaping scoop with 8-10 oz of water, milk, or your favorite beverage. For a middle tasting, less sweet shake, use 12-14 oz of liquid per scoop.



Blender: Add one heaping scoop of Gold Standard 100% Casein™ to a blender filled with 10-12 oz of water, milk, or your favorite beverage. Blend for 20-30 seconds. Then add 3-4 ice cubes and blend for an additional 30 seconds. Shake Up Your Shake: By adding a few high energy ingredients to your shake you can blend up a delicious meal: try adding fresh or frozen fruits (strawberries, bananas, peaches, etc.) peanut butter, flaxseed oil, yogurt, coconut, silvered almonds, or other ingredients. Stack Your Shake: By adding supplements like Micronized Creatine, Glutamine, Taurine, and/or Instantized BCAA powders, you can make Gold Standard 100% Casein an even more powerful post-workout recover product.

Spoon Stirred: If you forgot your shaker cup or dont have time to get out the blender, you can just add one heaping scoop of Gold Standard 100% Casein™ to a glass filled with 10-12 oz of cold water, milk, or your favorite beverage. Then mix it up with a spoon for about 30 seconds or until powder is dissolved.

Mixes in perfectly. The Vanilla flavour is the best and there is no clumping, even without using a shaker ball.

I've used this several times and it does the job. Taste wise it's ok, less delicious compared to it's Whey counterpart from the same brand. Tastes better with milk or soy.

Takes a bit of effort to mix, make sure you shake the shaker throughly to get an even texture.
