@Aerose91, my husband was taking HyB12 and AdB12 (+ L-carnitine).
2000 mcg HyB12
2500 mcg Dibencoplex (1/4 tab)
This combo worked to get him out of an overmethylated state (from taking the MeB12 & Mefolate). The HydroxyCbl mopped up the excess methyl groups and he felt good on this combo for over a month.
He has the double COMT mutations (both homozygous) and the MAO A (homozygous), so while the MeB12/ AdB12/ Mefolate protocol worked well initially, he became really messed up after a dose increase (neurotransmitter failure). Right then I raided his e-mail and found the "results are ready" message from 23andme, and figured out the trouble, and we went out and got some niacin.
Now he's back to the original protocol, but we've got the HyB12 and niacin on hand in case it happens again.
