i'll just throw out an arbitrary 200mcg. Not conservative by multivitamin standards, but definitely not excessive by life-extenionist standards.
do you think 200mcg is a sufficient dose for a positive methylation effect?
edit: we could also use dibencozide (aka adenosylcobalamin) if it's cheaper!
Seconded. Or is that
thirded...
It may be a little too early to tell, though. Methyl may have more advantages than just a few extra percentage points in bioavailability.
I DO remember seeing a study a little while back that said Cyanocobalamin was no less B-A than methyl and other popular forms, though... not sure how well done it was, but it seemed to be a human study testing some kind of level of it if I recall. I have no idea where it is now. I found that forever ago and didn't quite know what I had.
Still, I'd stick with Methyl since it's co-enzyme. If you wanted to bump up the count a little... well, I'd say use more methyl, but if it's the expense nail in the reasonable pricing coffin, maybe diben'll work.
