I think there are situations you can just "medicate" yourself with supplements and it works for you, but I also believe that something like diabetes is nothing to experiment with and spin the wheel of chance and see what happens.
Several months ago, there was a discussion on here about supplements and so I tried some of them and gave them to my husband because we went off our statins. What a HUGE mistake that was! Those supplements upset my stomach so much and kicked up my GERD that I couldn't lay down to sleep or hardly eat anything without being sick. My husband had a terrible case of diarrhea for weeks. Yes, we stopped taking them but didn't start taking statins again.
What I'm saying is...if it works for you...great, but it doesn't for everyone.
