Basic Vitamin Intake

Hello!  Is there a site, list, etc. available that tells one, in general, what vitamins AND what doses to take as a post-op?  Basically, I know it's... two daily multi-vitamins iron B-12 fish oil (option) calcium biotin ...but is there somewhere I can find out what mcgs or mgs are recommended?  Looking up the Recommended Daily Allowance doesn't help us anymore!  :)

I could use help in this area also, IAm tired all the time. And i have no idea why. Must be something I am not getting enough of.thanks for your help.
