l-carnitine

Heart Health – Do you need to supplement L-Carnitine?

This is probably a supplement you’ve never heard of, but when supplemented along with coenzyme Q10 substantial benefits have been seen in individuals with heart disease.

L-carnitine is a compound produced by the liver and kidneys from the biosynthesis of the amino acids lysine and methionine. To form L-carnitine you also need adequate levels of vitamin C, B6, niacin, and iron.

Let me explain how L-carnitine works. The powerhouse of your cells is the mitochondria and produces the energy your heart needs to function. L-carnitine is responsible for transporting fatty acids to the mitochondria for energy production. The heart typically gets 60% of its energy from fat sources. If this process is slowed due to a lack of L-carnitine heart function is affected, especially compounding problems for individuals with heart disease. Those with moderate to severe atherosclerosis (hardening of the arteries due to inflammation and cholesterol deposits) and congestive heart failure are most affected by a deficiency of L-carnitine. Too make matters worse, damaged heart tissue has a hard time “holding on” to L-carnitine resulting in a deficiency.

If you remember back to the information I shared on Coenzyme Q10, Coenzyme Q10 directly affects energy production in the mitochondria. When Coenzyme Q10 levels are low, cells are unable to produce energy, meaning the heart lacks the fuel it needs to pump blood.

About 85% of individuals with heart disease respond positively to coenzyme Q10 supplementation and significant improvements to their heart health. However, ~10-15% do not see any improvements from the addition of coenzyme Q10. Researchers have learned the “missing link” for these individuals is L-carnitine. The combination of L-carnitine with Coenzyme Q10 is needed for some individuals to experience the additional energy boost and improved heart function.

Signs of improvements many individuals see from a combination of L-carnitine and Coenzyme Q10 include better color, easier breathing, and less difficulty with exertion activities.
