Acetyl L-Carnitine

Acetyl-L-carnitine (ALC) is a form of carnitine that’s available as a supplement. Most of the cells in your body contain carnitine, which your liver and kidney make. It helps your cells produce energy.

Because L-carnitine plays a central role in energy production, many athletes begin taking it as a way to enhance endurance and boost athletic performance. Both human and animal studies have confirmed the beneficial effects of this amino acid on endurance levels.

While L-carnitine is primarily used to kick-start fat burning and enhance athletic performance, it also benefits brain health and memory. In other words, taking acetyl-L-carnitine can supply the same benefits as L-carnitine, with the bonus brain-boosting benefits as well.
