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.
Did you ever exercise so hard that you felt a muscle “burn”? During intense training, when lactic acid levels can 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 helps 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.
