Should I take a basic vitamin pill daily?

From 1989-1996, I used to take multivitamins, super Vitamin B, Vitamin C and other supplements I thought would be good for longevity and keeping disease at bay. I stopped using multivitamins because all studies, except those on Vitamin D, have proven to either not help, and in some cases, harm the user. Eating a balanced diet appears to impart the most benefits.

You should know that only 5 or 6 companies produce vitamins; it is an expensive process. Some companies might choose to buy select vitamins from a competitor due to cost restraints or because they cannot obtain the raw products to produce them.
