There are numerous benefits from taking acetyl l-carnitine supplements, but if you add in some acetylated ester, you get even more far-ranging benefits. This is a supplement that is recommended for anyone who is l-carnitine deficient, and getting those levels back up to where they should be ensures that your body is able to better use fatty acid substrate.
The fatty acids are broken down and then moved by CPT to muscles where they will be used up as energy. If you use an acetyl ester, though, l-carnitine will be absorbed more easily. On top of that, the ester will help the production of choline, which enables learning.
