LCarnitine LTartrate Powder (Lclt) is a form of Carnitine, a wellcharacterized amino acid naturally produced in the body to generate energy. The human body uses LCarnitine for fatty acid oxidation, the process in which fatty acids are broken down to create energy. In other words, LCarnitine helps the body convert fat into energy by moving it to the mitochondria to be burned as fuel. This burning process is called betaoxidation, where fat is converted to ATP or energy. When taken regularly as a supplement and combined with a quality diet and appropriate exercise, LCarnitine may help weight loss. LCarnitine is also taken as an enhancement for bodybuilding thanks to its excellent physical effects. Recent studies suggest that supplementing with LCarnitine LTartrate can upregulate the AR (androgen receptor), content, which may promote increased testosterone uptake and recovery from RE. LCarnitine LTartrate was shown to reduce muscle damage produced by an acute bout of highintensity RE in two crossover, placebocontrolled trials.
