L-Carnitine's ability to increase the human body's energy production by consuming its fat stores makes it a powerful fat burner. Inside the body's cells, L-Carnitine helps transport fatty acids to the mitochondria, where they can be burned for energy. In addition to this metabolic property, L-Carnitine has been shown to improve the neurological functions of the brain and facilitate muscle coordination in the body. Since L-carnitine helps increase mitochondrial function, it plays a key role in the body's fight against disease and healthy aging. L-Carnitine L-Tartrate is a more efficient and faster absorbing type of Carnitine. Combats muscle pain and helps tissue recovery during and after physical exercise. Plus, it strengthens the body's assault on fat stores, while also providing an energy boost.
