Acetyl-L-Carnitine (also called N-Acetyl-L-Carnitine) is one of the body’s basic building blocks, an amino acid that is involved in the production of energy, good heart and brain function, muscle movement, the metabolism of cells and many other bodily processes.

The body is capable of converting Acetyl-L-Carnitine into the closely related L-Carnitine, a substance that turns body fat into energy. It is also able to convert in the other direction. Your body makes both of these substances in the liver and kidneys, and they are packed away for future use at various sites around the body: in skeletal muscles, brain, heart and sperm, for instance. L-Carnitine, which sometimes is less available as a nutrient than Acetyl-L-Carnitine, is very important in the body, and having a more accessible version around helps with basic bodily function.

As a supplement, this amino acid reacts on the mitochondria in the cells of the human body. Because they are so vitally involved in the production of energy, boosting their production may lend an overall increase to physical and mental health.

Acetyl-L-Carnitine also has great potential as a treatment of many forms of disease. When taken in greater amounts than normally produced in the body, according to the Internet Drug Index, it has shown itself possibly effective against a wide variety of symptoms. It might be beneficial in loss of cognitive function and loss of memory in the elderly (such as those resulting from Alzheimer’s Disease or dimentia), for instance, as well as helping to rehabilitate stroke victims. It may also help with diabetes-induced nerve pain, male infertility and age-related testosterone issues.

Overall, this vital amino acid is very important to the body’s proper function, and when used in larger doses, may even provide a preventative against many symptoms of age and poor health. To read more about Acetyl-L-Carnitine, head to Dr. Weil’s Vitamin Library.
