I'd start with the Wikipedia page on vitamin C:

http://en.wikipedia.org/wiki/Vitamin_C

You can get time released vitamin C so you don't have to take pills
every hour.

I'd also avoid taking fractioned ascorbic acid. Vitamin C in food is
always present with many other compounds that are required for proper
assimilation. Organic rose hip powder is now available. Acerola powder
is also available:

It's not practical or cost effective to get all your vitamin C from
natural powders like this, but they are good compliments to vitamin C
supplements.

Also remember that the goal is to get most of your nutrients from
whole foods, not from pills. I take a few pills, but it's easy to end
up with a fist full.

Cheers,

Paul
