The Use of L-Carnitine And CoQ10 Supplements In the Treatment of Cyclic Vomiting Syndrome (CVS)
Co-Enzyme Q10, L-Carnitine and Amitriptyline Usage in Cyclic Vomiting Syndrome (CVS): A Research Study

This is a study with the principle goal being to learn about the use of L-Carnitine and CoQ10, two vitamin supplements that are currently being used to treat Cyclic Vomiting Syndrome, largely initiated by parents. We want to learn how effective these supplements are compared to standard treatment, at what dose, and what onset of action in order to initiate future prospective study on these supplements.
