People take Acetyle form for neurological benefits and the other forms for fat metabolization, increased energy, and other whole body effects. Fumarate and Tartrate forms do not cross the blood-brain barrier. **Q: Expiration date if I purchase now?** A: Mine is May 2018 **Q: Made in china or italy? reviewer states china, doctor's best web site states "contains biosint acetyl-l-carnitine, which is manufactured in italy"** A: Rome Italy.
