I've been taking CoQ10 for a couple years now just for heart health. Never knew about using it to try to help make a baby. After reading some of this thread, I just upped my dosage. I used to take 400mg a day, then lowered it to 200mg a day because of cost, but now raised it back up to 400. Anyone who knows of good quality for a lower cost, please post! I try to use coupons and buy the double pack at CVS when they have a BOGO sale.
