Acetyl-l-Carnitine is a building block for proteins that helps support cognitive health and brain function by producing energy, as well as stabilizing cell membranes. It is the acetylated form of l-carnitine, and the two compounds share similar energy- and metabolism-promoting properties. Found naturally in the body, acetyl-l-carnitine supports the availability of acetyl-CoA, an important energy-generating metabolite. In addition, it supports healthy mitochondrial function and cell membrane stability. The acetyl group from acetyl-l-carnitine is also responsible for the production of acetylcholine, an important neurotransmitter for optimal mental functioning. A multicenter trial of 481 volunteers indicated memory and behavioural support with acetyl-l-carnitine supplementation. In another randomized, double-blind study, three-month acetyl-l-carnitine supplementation provided statistically significant support for mental function, including memory and attention, compared to placebo.
