    Featured Ingredients

    Soy Protein Isolate – Not only is soy protein naturally high in essential amino acid, it also features heart-healthy isoflavones and antioxidants that have been found to reduce risk of cardiovascular disease and oxidative damage.

    Whey Protein Isolate – Whey protein is a complete protein that is especially high in BCAAs like leucine, and also contains a large amount of cysteine. Whey isolate is one of the most anabolic and beneficial protein sources to grow muscle and improve performance.

    Casein – Casein is another complete protein that digests slowly over a period of several hours, releasing anabolic and recovery-enhancing amino acids into the bloodstream throughout the day and night.

    Egg White – Egg whites are low in calories and an excellent source of dietary protein. It contains all essential amino acids your body needs to perform day-to-day functions and maintain your muscle mass.

    L-Glutamine – Glutamine is an amino acid that plays key roles in protein metabolism, cell volumizing, and anti-catabolism. It increases your ability to produce Human Growth Hormone, supports immunity, and improves glycogen accumulation following exhaustive exercise.
