Carnitine

This is a naturally occurring amino acid, and deficiencies of this small but essential com­ponent can result in muscle loss and a multitude of other problems. Research abounds for carnitine, especially acetyl-L-carnitine, which is considered to have more bioavailabilty in terms of its effect on aging and brain function. But how this amino acid affects skin when applied topically is unknown (Source: www. naturaldatabase. com).
