Acetyl-L-carnitine is a dietary supplement and powerful antioxidant. Carnitine is synthesized from two amino acids and is found in almost all cells, but it's most abundant in cardiac and skeletal muscles. It transports long-chain fatty acids into the cells' mitochondria to be used as fuel, thus playing a major role in energy production; it also transports toxins from the mitochondria, preventing their accumulation. Carnitine is made in the liver and kidneys, but in some cases supplements may be required or beneficial.
Delays Aging
According to the Office of Dietary Supplements, delay in aging is one of the possible benefits of acetyl-L-carnitine. The mitochondria in cells are major sites of energy production for cells, and impaired function can contribute to aging. High supplemental doses of acetyl-L-carnitine, together with alpha-lipoic acid, another powerful antioxidant, can help reduce mitochondrial decay. For older patients, acetyl-L-carnitine can also help improve mental function, cognition and memory.
Improves Male Fertility
Men who are unsuccessful in getting a woman pregnant after trying for at least 1 year may suffer from male infertility, according to Medline Plus. Acetyl-L-carnitine can help with male infertility, since this amino acid can help improve sperm motility, quality and count. Acetyl-L-carnitine can also help reduce cell death in the testes.
Delays the Progression of HIV and AIDS
Delaying the progression of HIV and AIDS is among the benefits of acetyl-L-carnitine. The HIV virus causes a steady decrease in a subset of lymphocytes, a type of white blood cell. Eventually these cells die out, making the patient prone to many kinds of severe infection. Oral or intravenous acetyl-L carnitine at doses of 2 to 6 g per day for several weeks or months may slow the death of lymphocytes and delay the progression of HIV disease.
Helps Alleviate Cancer Symptoms
Acetyl-L-carnitine can help alleviate cancer symptoms. Cancer results from the abnormal growth of malignant cells and tumors. Treatment options include surgery, radiation and chemotherapy. Taking carnitine supplements in doses of 4 g per day can help minimize the fatigue related to cancer and its treatment. Terminal cancer patients taking carnitine can also experience improved mood and better quality of sleep.
