There are many studies showing lower rates of
various diseases among people taking vitamin supplements.
Some studies show lower rates of "death from all causes".
This suggests that the optimal amounts are larger
than in a typical diet.

I would be curious to know whether any of these were controlled
studies with people being randomly assigned either an active
supplement or a placebo. In an uncontrolled study, where the
participants decide for themselves whether to take supplements,
it may be that the supplement users are more health conscious,
get more exercise, etc.
