A mega-dose of a non water soluble vitamin would work great since you can store it in fat - like vitamin A. However, vit C and zinc are water soluble so you'd just pee out the excess and be deficient again in a few days without a regular dose. (more)

Linus Pauling, the only man to win an unshared nobel prize twice seemed to think that heart disease was a case of chronic scurvy that could be corrected with vitamin c and lysine. Do you agree or disagree with this position, why or why not?

I did not know that, but I just see it as a reason to eat more limes. I like limes better than lemons.
