will methylfolate still recycle BH4 if I...high dose methylation and niacin together

[vortex]

will high dose methylfolate still recycle BH4 if I purposely take niacin to soak up the excess methyl groups ?

I would like to take higher dose methylfolate for the purpose of recylcing BH4 like deplin attempts to do in order to boost neurotransmitter levels, but I run into overmethylation symptoms from excess methyl groups, so since you can take niacin to counter act this and soak up excess methyl groups it would seem like it could be a solution to symptoms, but would taking the niacin also prevent the goal of more BH4 or would that get negated too by the niacin ?

I guess I dont understand if they are tied to each other directly or not.

thanks
