Very important in energy metabolism. Might beef up cognition. Is helping metabolize food into energy. Might significantly scale back severity of depression symptoms. Significant improvements in exercise performance. Profound effects on staying power. L-Carnitine facilitates the metabolism of fatty acids for energy generation. A better reliance on fat for energy can lead to a sparing of muscle glycogen, an enhancement of exercise performance, and a discount in stored body fat. L-Carnitine has a profound effect on staying power and exercise performance that works by reducing the respiratory exchange ratio and decreasing lactic acid accumulation in muscles. This ends up in extended exercise capacity before the onset of fatigue.
