What is the difference between Acetyl-l-Carnitine (ALC) and L-Carnitine?
A12: As with many amino acids, L-carnitine can be found in several forms. ALC is the acetylated form of L-carnitine know to be a more stable form of L-carnitine. Interestingly, ALC passes the blood brain barrier more efficiently than L-carnitine. Hence, ALC has been the focus of research involving memory and cognition enhancement while L-Carnitine has been the focus of research in the area of cardiovascular health.
