L-Carnitine is an amino acid compound of lysine and methionine. L-Carnitine has shown the ability to improve oxygen delivery to the heart muscle, promote cardiovascular energy, raise endurance, and support healthy lipid metabolism. 95% of the body’s carnitine is stored in muscle tissue. Increasing the amount of L-Carnitine stored in the muscles promotes faster transformation of fats into energy which may lead to fat loss and increased energy. L-Carnitine has also been shown to speed up recovery after exercise by reducing lactate buildup in the muscles, resulting in less pain and soreness. Lactate buildup leads to muscle pain and lowers performance, thus producing smaller amounts means a faster recovery. L-Carnitine can be synthesized in the liver; however some have difficulty producing sufficient amounts. An L-Carnitine supplement can help to obtain optimal levels. L-Carnitine Benefits  Better fat metabolismIncreased energy levelsImproved athletic performanceIncreased enduranceGreater work out capacityFaster post-exercise recoverySupport for healthy heart and muscles L-Carnitine Tartrate Advantage L-Carnitine Tartrate is the only type of Carnitine with extensive clinical studies to back up its benefits. A study in The Journal of Physiology examined the effects of L-carnitine supplementation on athletic performance. Professional athletes in training taking L-carnitine tartrate for 24 weeks saw an 11% improvement in performance where the placebo group had no change. Another study had athletes taking l-carnitine tartrate for 3 weeks and discovered that after intense workouts, the participants had reduced muscle tissue damage. ## Features - BOOST YOUR ENERGY AND ENDURANCE: L-Carnitine is a powerful fat burner that plays a key role in fat metabolism.
