L-carnitine is synthesized in the body from the amino acids lysine and methionine. It is also found in avocados, dairy products, and red meats (especially lamb and beef). L-carnitine transfers long-chain fatty acids, such as triglycerides into mitochondria, where they may be oxidized to produce energy.

L-carnitine is synthesized in the body from the amino acids lysine and methionine. It is also found in avocados, dairy products, and red meats (especially lamb and beef). L-carnitine transfers long-chain fatty acids, such as triglycerides into mitochondria, where they may be oxidized to produce energy.
Studies have been conducted on L-carnitine since as early as 1937. Those studies yielded positive results suggesting that the body's cardiovascular system can greatly benefit from its intake. There are a variety of published studies that suggest L-carnitine is useful in increasing the heart's output and improving it's functioning, as well as stimulating the heart's energy supply and supporting cardiac performance.
L-carnitine promotes fat burning, essential for the integrity and function of the cell, protects cell membrane, reduces liver fat accumulation and increases the antioxidant capacity of vitamin C and vitamin E. L-carnitine can promote an increases in the number of androgen receptors in the muscle, and prevents further nerve damage due to diabetes.
A deficiency in L-carnitin causes derangement of sperm metabolism leading to infertility.
Anyone deficient in protein or amino acids in their diet could benefit from L-carnitine supplementation. Pre-mature infants, vegan vegetarians, children, and breast-feeding women are likely to be deficient.
Deficiency in L-carnitin could lead to muscle weakness, hypoglycemia and high blood ammonia level.
