L-carnitine, also known as levocarnitine, is a naturally occurring amino acid structure that the body produces. People can also get it from their diet or take it in the form of an oral supplement. L-carnitine plays a critical role in energy production, as it converts fat into energy.
Most people will get enough L-carnitine from their diet or their body’s production of this compound. Those with low L-carnitine levels may benefit from taking an oral supplement, though.
L-carnitine L-tartrate: Athletes may use this type in the form of sports supplements. Research suggests that it may be useful in minimizing muscle soreness and aiding recovery.
L-carnitine, and carnitine in general, is a key component in creating energy for the cells. Its main function, helping break down fatty acids for use as energy, keeps the body’s cells powered and working efficiently.
L-carnitine also has a secondary function of helping remove some waste products from the cells to prevent them from accumulating and causing problems.
