For most people, the body naturally produces enough L-carnitine to meet their needs
However, as with any supplement, you should speak with a doctor before taking L-carnitine
It remains to be seen how practical and cost effective daily supplementation of carnitine with carbohydrate is Carnitine and endurance exercise The belief that carnitine is an ergogenic aid for endurance exercise is based on assumptions similar to the weight-loss assumptions: Carnitine concentration in muscle becomes too low to allow the transport of carnitine into the mitochondria to function at a high velocity Oral ingestion of carnitine increases the total carnitine concentration in muscle Any increase in muscle carnitine increases the oxidation rate of plasma FAs and intramuscular triacylglycerols during exercise Any increase in fatty acids will reduce muscle glycogen breakdown and postponing fatigue
In a series of studies, it was observed that it is possible to increase muscle carnitine concentration if carnitine is given when plasma insulin concentrations are elevated
People who avoid animal products, such as those following a vegan diet, may get around 1 to 14.5 mg from their diet
It also helps suppress appetite by increasing serotonin levels, which further helps reduce appetite & cravings
