L-CARNITINE

L-Carnitine is an essential amino acid that the body uses to move fatty acids into the cell's mitochondria, which is the cells power plant. In a study of 18 overweight subjects, l-carnitine greatly increased weight loss. The subjects were split into two groups of 9. For 12 weeks, both groups ate a healthy diet and performed moderate exercise. One group was given 2000 mg of l-carnitine, and the other a placebo. In the placebo group, the average weight loss after 12 weeks was one pound. In the l-carnitine group, weight loss averaged 11 pounds. That’s an eleven-fold increase in weight loss, simply by increasing l-carnitine levels. Body fat percentage levels also decreased markedly in the licarnitine group.

L-carnitine can be synthesized within the body from the amino acids lysine or methionine with a little help from Vitamin C. It is essential to help convert food into energy, hence the reason it is included in many energy drinks. l-Carnitine also has beneficial effects on the cardiovascular system and helps improve resistance to muscle fatigue.




Several studies have been done to discover the impact that L-carnitine has on the body following exercise.. Researchers have tested people at all athletic levels, with and without adequate L-Carnitine, for indicators of recovery. They found that people had significantly less post-workout pain and tenderness and less post-exercise muscle damage with L-Carnitine supplementation than with placebo. In one study, 75 percent of participants saw a 20 percent improved ability to exert energy within the 25-minutes after exercising.

Scientists suggest that L-Carnitine may help deliver more blood and more oxygen to muscle during exercise, which helps improve energy generation, wash out substances that produce painful symptoms and repair damaged muscle.

L-Carnitine is produced in small amounts in the human body (approximately 20 milligrams daily), but this is only 10 percent of the nutrient used daily by the average person and about one percent of the amount needed for enhanced exercise recovery. A 16 ounce can of energy drink usually contains about 50 mg of l-carnitine.
