Where does L-Carnitine occur in the human body?

L-Carnitine occurs naturally in the body, in total about 20-25 grams. Organs and cells with a high energy requirement such as the heart, muscles, immune cells, brain, nerves and sperm contain highest levels of L-Carnitine and cannot function properly without an adequate supply.

Our body is able to produce small quantities of L-Carnitine, if precursors (two essential amino acids, lysine and methionine) and cofactors (vitamins C, B3, B6 and iron) are readily available.

An inadequate supply of any of these nutrients restricts the body`s ability to produce L-Carnitine.
