I understand supplements are subjective but I just read that taking Coenzyme Q10 during IVF can have negative impacts. I wish I knew it sooner as I did not stop this during my last 2 cycles. CoQ10 generally is used to improve egg and sperm quality hence should only be taken before egg retrieval, it has not been studied well during IVF cycle and pregnancy hence unless being advised it should not be taken.
What are you taking when your transfer begins? Are you continue taking your pre-conception multi vitamin tablet as it does contain CoQ10 or are you taking folic acid as a single pill?
