This product comes in many flavors such as Banana Cream, Chocolate Cake Batter, Chocolate Supreme and Creamy Vanilla and has one of the highest protein content found in protein powders. It also contains over 9 grams of BCAA’s and Glutamine per scoop. Optimum Nutrition 100% Casein Protein Powder allows protein to be released slowly which is essential for body building, as the exercises take time and many repetitions to complete. The muscle builds as the protein gets released which in turn sculpts the muscles optimally through time.
Shawn Wells , a diet and nutrition expert and chief scientific officer at BioTRUST Nutrition, says, “Ninety percent of the time, proprietary blends are about listing things for marketing purposes and saving a lot of money.” He explained that “people think they are getting all these listed ingredients, but out of a total of 4,000 mg of a supplement, 3,999 mg could be, say, creatine, and only 1 mg could be BCAAS, which is what you really want. There’s no way to know.” He added that proprietary blends can also pose a danger when they contain certain ingredients, say, stimulants like caffeine or synephrine, which can be unsafe in larger doses.
Creatine has been found to increase the replenishment of ATP stores in the skeletal muscles (22). It is attributed to a greater rate of phosphocreatine resynthesis during the rest periods. Higher sprint speeds reported (23). There have been numerous theories proposed as to why creatine is a benefit to short term high intensity exercise (24). One theory is that the increased amount of phosphocreatine, (PCr), can be used as an immediate buffer to ATP which reduces the dependence of glycolysis which delays the production of lactate and hydrogen ions during exercise thus prolonging the activity by delaying the onset of fatigue, (25).
