I use old yeast slurry as a nutrient occasionally. It seems to work well, but it is hard to tell. It is my understanding that SERVOMYCES is made from yeast which is where I got the idea. I just add the slurry to my boil. I would be interested at what others on the forum think about the idea.
Pretty sure it's B1 a.k.a. thiamine that is the one for cell growth. Haven't checked out B6, though it likely does no harm.....-----snip-----
3) B Vitamin pills - when I want my yeast to have a boost to colony growth and I am low on DAP or yeast energizer I will use one 100 mg pill of B6 in a gallon to help promote cell growth. A B Complex pill would be good as well.

Thanks for all answers until now!
I really think this a great thing to debate. I was studing a little aboute nutrientes when came this idea of manipulate my own. So I think that we should start making the nutrient using yeast cell hulls, thiamin (B complex) and I also found a research work here in Brazil about the protective effects of magnesium against alcohol and temperature stress on yeast.
