A few days ago, I shared a little information on the nutrient L-carnitine. I want to give you a few more details related to this nutrient.

Let’s review the function of L-carnitine. In order for the heart to pump blood it needs fuel. This fuel is produced in the mitochondria of your cells. The hearts preferred energy source is fatty acids. Coenzyme Q10 is needed for the production of ATP (fuel) within the mitochondria. L-carnitine is needed for the transport of fatty acids to the mitochondria. Most people with heart disease are deficient of coenzyme Q10 and benefit from supplementation. Some individuals with heart disease are also deficient in L-carnitine and will only see improvements if Coenzyme Q10 and L-carnitine are supplemented together.

Even though your body can produce L-carnitine deficiencies do occur. A deficiency can be caused by aging, vegetarian diets, diet deficient in iron, diets low in the vitamins B6, niacin, and vitamin C, liver disease, kidney disease, and certain medications (such as anti-convulsant drugs). As I mentioned above, a damaged heart also promotes an L-carnitine deficiency.

Combined supplementation of L-Carnitine and coenzyme Q10 have improved many cardiovascular situations:

1. Angina
2. Congestive Heart Failure
3. Renal insufficiency
4. Arrhythmia
5. Hyperlipidemia (high cholesterol, high LDL cholesterol, high triglycerides)
6. Leg Cramps

Some sources of L-carnitine include mutton, lamb, beef (red meat), and pork.

There are two forms of L-carnitine available at health food stores – fumarate and tartrate. So far, L-carnitine tartrate has been found to be more efficient for individuals with heart disease. New forms of L-carnitine are being researched and may become available, also.

While there are no known side effects from supplementing L-carnitine, always consult your physician regarding any and all supplements you currently take and/or would like to supplement.

All the best,
