Off Topic...

SA Friday, I know you study chemistry but not only that, it seems like you LOVE IT. For that I say...nerd. Kidding.

I did some chemistry while getting an engineering degree and while I didn't think it was extremely difficult (rather basic classes of course), I was not fond of it in the slightest.

I hope your love of chemistry pays off and you invent the next Viagra or something.

Back on topic....now.

How long can one store something like a vitamin C supplement? That is a biggie in my book. I don't want to get scurvy when SHTF and I don't know of many citrus trees in CO. Rose Hips have lots of vitamin C but we don't have tons of roses either. Vitamins in a bottle seem like the best bet.
