Carnitine
Fatty Acids are a major source of energy for the body. They are broken down
inside mitochondria to produce energy in the form of ATP.
However, fatty acids are unable to cross the inner mitochondrial membrane
without the use of
Carnitine.
Carnitine is found abundantly in some meat, small amounts in fish, with tiny amounts in fruit and
vegetables.

Human adults store about 20 grams of L-Carnitine, primarily in
skeletal muscle, in the liver, and in the heart. L-Carnitine is not metabolized
or degraded, but excreted in the urine, mostly in the form of
Acetyl-L-Carnitine. Therefore, lost L-Carnitine has to be replenished by
biosynthesis, by the consumption of foods of animal origin or by consumption of
dietary supplements.

Although I don't have any medical qualifications,
as a sufferer of Diabetes, Deafness and Tinnitus caused by the A3243G mtDNA defect,
I do have a very keen interest in the subject.
