Check your vitamin D level, if low, take vit D. Also, inositol helps increase insulin sensitivity. Acetyl L-Carnitine pushes energy into cells. Co-Q10 and fish oils helps reduce inflammation. You probably need all of them together with acupuncture for 3-4 months in order to see effects. But it works! Good luck!
You'll most likely need to see your doctor as they can prescribe something to help start your periods, I don't think vitamins are going to help pcos.
