Acetyl-L-Carnitine is a compound normally found in the horse’s body. It is produced from another compound, L-Carnitine, which the body synthesizes from the amino acids lysine and methionine. This naturally occurring amino acid helps the body mobilize fat for energy.
It is necessary for moving long chain fatty acids into the mitochondria to be burned. Studies have shown that availability of free carnitine in the muscle cell influences the relative rate of burning of fat or carbohydrate.
