I cannot rave enough about this product!!! I went on it years ago and then felt better and let myself run out..In time the pain returned and I also developed ovarian cysts.. Lots of pain and they wanted to do surgery asap.. Periods were irregular up to 6 months without it.. Went back on Endovan, within two werks had a full cycle.. Periods have been more than regular and pain free!! Had another followup ultrasound done today, ALL MY CYSTS ARE GONE!!! I ONLY attribute this to Endovan!! Two years these same cysts were there! THANK YOU !!!! I thank God for Endovan and the people who created it!!!
