I was taking 50mg 2x/day of ubiquinol and d-ribose together with the MACA but stopped before I took the methyl B12. Perhaps some is still in my system? Stuff stays in my system for long time. Why do you ask @Critterina?
Thankfully I had my DNA done and found out what B 12 I needed for years I was on crappy cyno and then learned about Methyl and taking that but never felt better, so then I realized after looking at Amy Yazko site, with my DNA COMT and VDR issues I needed hydrox b12 making a big difference for me..
