Carnitine is a compound made by the human body that helps break down fat into energy by transporting fatty acids into the mitochondria of your cells. Carnitine can be consumed through red meat, dairy products, avocados, and soybeans. However, many people may not consume enough, making it harder for them to use fat as energy. Studies have shown that carnitine supplementation can improve exercise performance, increase in muscle mass, decrease muscle soreness, and higher cognitive function especially in vegetarians, overweight individuals, and older adults [1][2]. Bodybuilding.com Signature L-Carnitine provides 500mg of Carnipure ® L-Carnitine Tartrate in easily digestible individual capsules. This formulation comes from a high quality source and has a faster absorption rate than other L-carnitine compounds [3].
Many athletes use carnitine to raise their carnitine content in order to modify their muscle metabolism and increase their exercise performance [4]. Since 98% of carnitine is found in skeletal muscle tissue, carnitine may play an important role in healthy aging by reducing fat storage, assisting in protein production, and increasing mitochondrial functionality [5]. There are also other studies exploring the benefit of l-carnitine for reversing the decline in brain function with Alzheimer's patients [6]; as well as reducing hypertension, insulin resistance, and impaired glucose tolerance [7]. Many individuals may benefit from regular long term supplementation of carnitine.
