Long used by athletes to improve strength and exercise performance, creatine is being recognized as more than a muscle-building supplement. Creatine is present in the body. Skeletal muscle, heart, brain, and other tissues metabolize creatine and use it as a major energy storage form.55-62 Creatine boosts levels of ATP in the mitochondria, the cell’s energy powerhouses.63-65
While studies have shown that creatine may indeed help build muscle and strength in explosive short duration activities, other research has demonstrated the supplement’s role in enhancing healthy muscle mass in aging humans.6,54,55,66
Whey protein isolate can build lean muscle and prevent protein breakdown. It has also been shown to enhance the production of glutathione, the body’s natural antioxidant. Glutathione detoxifies harmful compounds in the body and boosts cellular immune function. In immune-compromised individuals, whey protein has been shown to enhance glutathione levels, thereby helping to maintain immune function.67-71*
Glutamine is a nonessential amino acid that generates energy and helps to increase strength, quicker recovery, and exercise endurance.72-74 Blood ammonia concentration increases during endurance exercise and has been proposed as a cause for both peripheral and central fatigue. In recent trials, glutamine supplementation reduced the accumulation of blood ammonia during prolonged, strenuous exercise in high-level athletes.75,76 As an immune booster, glutamine supplementation may prevent the negative effects of strenuous exercise on the immune function. Moreover, glutamine supplementation has a protective effect in the DNA fragmentation, mitochondrial membrane depolarization and apoptosis, and in regulation of the inflammatory process and immune suppression, which are induced by a single session of exercise.77-79 Glutamine also plays an important role in maintaining functional integrity of the gut. As a guttrophic factor, glutamine improves intestinal function, allowing better absorption of nutrients.80-83*
Life Extension’s Creatine Whey Glutamine Powder contains micronized creatine for optimal assimilation. The whey has gone through a cross flow microfiltration process, which allows the product to retain its important subfractions in natural proportions. |
