What is L-Carnitine?
L-Carnitine is not an amino acid in the strict sense (it is not used as a neurotransmitter or in protein synthesis). However L-Carnitine bears many resemblances to amino acids and is usually grouped under this heading.
L-Carnitine (the "L" refers to its chemical polarity) is used by the body to transport long-chain fatty acids to the mitochondria in your cells, where they are burned for energy. Since this fat burning is such a major source of muscular energy, deficiencies in L-Carnitine are manifested as low energy levels and muscular weakness.
L-Carnitine deficiencies can also appear as mental confusion or cloudiness, angina (heart pain) and weight gain.
