"Do you know anything about the use of CoQ10 during pregnancy?  I take it for my heart as I have a heart condition and things have improved immensely for me.  My doc says it's unbelievable and to keep doing what I'm doing.  I am getting mixed answers on CoQ10 use during pregnancy since there has been no testing so I am wondering if you or any of your readers know of or have heard anything."

All Google searches are revealing that the information out there is inconclusive and contradictory. If anyone has any information about CoQ10 (an enzyme) and pregnancy, please leave it in the comments or email me directly.

Thank you.
