L-Carnitine
L-carnitine is a non-essential amino acid that is made by the kidney and the liver and is derived from the amino acids methionine and lysine. Carnitine plays an important role in transporting long-chained fatty acid across the mitochondrial membranes in cell in order to produce energy. Recent research has determined that carnitine may play a role in lowering cholesterol and triglyceride levels, as well as improving cardiac performance.
Special Precautions of L-Carnitine
- Under-active thyroid (hypothyroidism): Taking L-carnitine might make symptoms of hypothyroidism worse.
- Seizures: L-carnitine seems to make seizures more likely in people who have had seizures before. If you have had a seizure, don’t use L-carnitine.
- Individuals who are taking valproic acid or zidovudine, since these drugs can deplete carnitine from the body. ·
- Individuals with liver disease should consult their health care practitioner or pharmacist before taking L-carnitine. ·
- If you have an underlying condition, or on other medications, be sure to consult with a pharmacist or your health care practitioner before you begin to take arginine.

The benefits of L-Carnitine are
L-carnitine has been used as a supplementative treatment in patients who have high cholesterol levels. Previous research has also indicated its use in cardiovascular disease, infertility, enhancement of athletic performance, and weight loss.
Where is L-carnitine normally found? There is enough arginine made by your body, so supplementation is not generally required. It is also found in a variety of meat and dairy products.
How much do I take to lower my cholesterol levels? There is currently no RDI established for L-carnitine, however, doses tend to average between 500 and 2000 mg a day.
How do I know if I am deficient in carnitine? Arginine deficiency is rare, since your body makes the arginine it needs. Symptoms of a carnitine deficiency include muscle weakness, stiffness, or soreness, impaired glucose control, high cholesterol and dark reddish-brown urine. These symptoms could be the symptoms of antoher disorder, so you should consult your health care practitioner if you experience any of these symptoms.
