Keep LDL in Check with L-Carnitine
LDL cholesterol is known far and wide as the "bad" cholesterol, but in fact that’s a bad rap. The truth is we need cholesterol, including the LDL kind. But when free radicals in the body oxidize LDL cholesterol it does indeed turn from friend to foe, building up in artery walls -- it is one of the substances that lay the foundation for dangerous plaque.
Recently an Italian study demonstrated that one way to reduce oxidized LDL levels is by supplementation with the amino acid derivative L-carnitine. Researchers randomly assigned 81 patients with diabetes (who are prone to cholesterol problems) to one of two treatment groups. One group received placebo and the other received 2 g of L-carnitine once daily. At the end of three months, the L-carnitine-treated patients showed a decrease of oxidized LDL levels compared with the placebo group. This was just the latest study on L-carnitine.
THE MANY USES OF L-CARNITINE
According to Mark Stengler, ND, regular contributor to Daily Health News, L-carnitine helps with various health problems and its benefits are not limited to people with diabetes. When I spoke with Dr. Stengler, he rattled off an impressive list of benefits, noting that L-carnitine -- or carnitine as it is also called -- helps get energy to the heart muscles and is therefore beneficial to a number of cardiac conditions (angina, ischemia-induced arrhythmias, cardiomyopathy and congestive heart failure). It has also been used as therapy for myocardial infarction to help minimize muscle damage as a result of the oxygen reduction... it is helpful for chronic fatigue syndrome and kidney and liver disease... and there’s yet more. Studies have shown that carnitine (in the form known as acetyl-l-carnitine) may help ease the discomfort of peripheral neuropathy, a condition often triggered by diabetes or chemotherapy drugs that causes nerves in the feet and sometimes the hands to develop painful burning and stinging sensations. It appears that carnitine may even help peripheral nerves regenerate, though this is a preliminary finding. A variety of small studies have looked at the possibility that carnitine also boosts athletic performance given its role in energy production, but thus far none has shown any positive effect. However, Dr. Stengler told me that several of his patients who engage in endurance sports such as long-distance running seem to benefit from it. Dr. Stengler says people with elevated LDL but who do not have diabetes can also benefit from taking carnitine to help them prevent LDL oxidation from taking place.
