What is Creatine? Creatine is an interesting molecule that is synthesized in the liver from three amino acids - arginine, methionine and glycine. 95-98% of creatine is stored in the major skeletal muscles of the body while lesser amounts are found in the heart, brain and testes. Once creatine enters the muscle, it is phosphorylated to form creatine phosphate, which is a high-energy substrate that assists in the contraction of the muscle fibers. Spark Your Muscle's ATP Reserves During exercise, creatine is used by the body to maintain adequate levels of energy-rich ATP. ATP (adenine triphosphate) is your body's premier source of energy for many metabolic processes. Athletes who seek to achieve optimal performance during high intensity exercise will often load creatine as a nutritional supplement to spark their ATP levels. Muscle Strength and Energy Did you ever exercise so hard that you felt a muscle "burn"? During intense training, when lactic acid levels can often rise higher in muscles, you may feel a burning sensation in the muscles. Research shows that creatine can help buffer lactic acid that builds up in muscles during exercise. To help control the buildup of lactic acid and the burning sensations that can be created, creatine can help absorb and bind hydrogen ions that have been released into muscles. Creatine also promotes the body's anabolic phase for increased protein synthesis which supports lean body mass and muscle strength. Taking creatine supplements before and after workouts may help support muscle energy levels because it enables the ATP energy cycle to continue for longer periods of time. The "Clean Source" Quantum Creatine Monohydrate is a free-flowing, easy-to-use, natural source of creatine that you can use to load before and after your workouts. This "clean product" has the additional benefit of no added chemical binders, fillers or other non-nutritive substances.
