I agree, supermarket vitamins are worthless. There are quite a few independent studies to support that, hence why I only support purchasing pharmaceutical grade for my own needs.
I am not exactly sure what portion of my post indicated that the vitamins I take are in ultra high doses, but that is a common misconception that I often hear. The difference between normal vitamins, and pharmaceutical grade, lies in the bioavailability of said nutrients to the body from digestion. Many of the compounds in normal multivitamins are both sensitive to gastric juces, and some have a secondary problem of being hard for the body to absorb all together. Pharmaceutical grade vitimins ensure that 80% (often more) of the amounts listed on the package are actually bioavailable. The FDA only requires that 10% (from memory) is actually required to be in the package, while none of it has to actually be bioavailable! (admiralty my numbers on the FDA could be off, I need to look that up)
Eating fresh fruits and vegetables is great, and I won't argue with that (because they are 2/3 of my daily diet), however I know it is impossible for me to buy the correct variety or quantity to correctly supplement what I believe is needed for my age, and activity level.
Regardless of what I think, I have no doubt that each side can post up an equal amount of studies to support their beliefs, but in the end, it is your personal choice what you put into your body (much like the flu shots).
I have attended nutrition seminars, read books, and listened to podcasts regarding both sides, and decided to go the route I did. Either way, I believe both are better than eating McDonalds every day, and sitting on your couch watching Daytime television
