Although the body can convert L-Carnitine to Acetyl-L-Carnitine and vice versa, different forms of carnitine are effective for supporting different functions. L-Carnitine is essential for transporting long-chain fatty acids across the mitochondrial membrane for subsequent fat breakdown and energy generation. The heart gets 70% of its energy from fat breakdown. Because of its role in energy generation, L-carnitine has a broad array of health benefits including weight management, recovery after exercise, cardiovascular health, male fertility, and healthy aging.*

Description: Although the body can convert L-carnitine to acetyl-L-carnitine and vice versa, different forms of carnitine are effective for supporting different functions. L-Carnitine is essential for transporting long-chain fatty acids across the mitochondrial membrane for subsequent fat breakdown and energy generation [1]. L-Carnitine also shuttles short chain fatty acids from inside the mitochondria to the cytosol. Therefore, L-carnitine is, in part, responsible for maintaining energy metabolism throughout the body [1].

 

What is L-Carnitine?

L-Carnitine is considered a non-essential amino acid because it can be made in the body from acetyl-L-carnitine, however, supplementing different forms of carnitine can be effective for supporting different functions. L-Carnitine is essential for transporting long-chain fatty acids across the mitochondrial membrane for subsequent fat breakdown and energy generation [1]. L-Carnitine also shuttles short-chain fatty acids from inside the mitochondria to the cytosol. Therefore, l-carnitine is, in part, responsible for maintaining energy metabolism throughout the body [1].

 

How does L-Carnitine Work?

L-Carnitine is especially relevant to cardiovascular energy metabolism, as the heart gets 70% of its energy from fat breakdown [2]. Carnitine levels in the heart are quickly diminished during ischemic events, and supplementation with L-carnitine has been shown to replenish depleted myocardial carnitine levels for efficient cardiac metabolism and, specifically, left ventricular function [2].

Supplementation with L-carnitine has also been linked to improvements in muscular potential [3]. While a great deal of research has been dedicated to carnitine supplementation for enhanced lipid oxidation, spare muscle glycogen, and improved exercise performance, the most significant benefits of L-carnitine, in terms of performance, have been documented in populations with certain existing health conditions, particularly those with various forms of cardiovascular disease [3, 4]. The muscular benefits of this supplement for the general, healthy population appear to be related to the recovery process after exercise [3]. L-Carnitine has been shown to reduce tissue damage, facilitate the overall process of recovery, and reduce muscle soreness [3, 4].

Because of its role in energy generation, L-carnitine has shown a broad array of other health benefits including weight management. Scientific investigations conclude that L-carnitine may decrease fat deposition in favor of protein deposition and improve the utilization of dietary fat [1]. Additionally, increased fat breakdown observed after L-carnitine supplementation is not accompanied by any observed protein breakdown, indicating a synergistic role for this nutrient in a weight management plan that includes regular exercise [1].

L-carnitine supplementation has also been shown to support male fertility [5,6]. Part of the physiological role of the epididymis is the secretion of relatively high levels of carnitines for energy metabolism within spermatozoa [5]. By providing readily available energy for use by spermatozoa, and thus positively affecting sperm motility, maturation, and the spermatogenic process, L-carnitine likely plays a key role in sperm quality.

L-Carnitine also has a protective effect on DNA and membranes against damage induced by free oxygen radicals [5]. The multi-faced antioxidant effects of L-carnitine demonstrate value for this supplement in healthy aging [7].
