To start with the Benfotiamine, I'd do 300mg a day in divided doses for at least two months.

I use Doctor's Best now for all my special supplements except B12.
I've found them better than NOW (for tryptophan) and
Theanine (Swanson's).

I've used the R-lipoic from them for several months now, and
always have used their Benfotiamine.

They are reasonably priced at iherb.com and Amazon now.
