Ryuji Suzuki in (there was a url link here which no longer exists) claimed that some vitamin-B derivatives "worked well".
BTW, have you been trying any of your developers with vitamin-C? Some might be superadditive with it.

I haven't yet tried any vitamin B stuff yet, I've tried only a couple amino acids in the past with little luck.
It could be excess exposure causing the grains (emulsion) to form Silver metal in the absence of development. This is called print out. It is not unusual.
But, with all of this work, it would be nice to see some scanned examples.
Thanks.

here's something from the test of dextrose w/o KBr on 3-12-2012
I looked up the formula for Vitamin E and it contains rings of 6 carbon with an OH attached.This is similar to Hydroquinone,Pyrogallol,Pyrocatechin and it might be superadditive with Phenidone.It's only a possibility and I think it depends on each compound individually.
You have found some interesting things, I was surprised the glucose worked.
