Are vitamin supplements good for health?

Almost every place that I go to, I see stores and stores just devoted to selling vitamins and more vitamins, and I was wondering what the benefits are of a normal healthy person taking vitamins daily. Are there any risks for a normal healthy person who doesn't take vitamins? Will the person taking vitamins' health be improved or have longer longevity? Will the person not taking any vitamins be as healthy as the person who is taking them? And also, what will happen if a person takes more than he or she should consume every day?


Why do I feel unrested when I dream?

I go through phases where, when I sleep, I don't have any dreams (that I remember, at least). I sleep well and I wake up rested. Every few months I go through a week or two when I have nights full of incredibly vivid dreams and I wake up remembering at least five or six of them. Because of all these vivid dreams, I wake up feeling far less rested than I do when I don’t dream at all. Is there a particular reason for this? Does dreaming more at night mean your sleep is less restful?


Is it possible to get BSE (mad cow disease) from gelatin?

I would like to know if I should be concerned with the risk of contracting "bovine spongiform encephalopathy (BSE)" or its human variant, from the use of vitamins, supplements, over-the-counter medication, or pills prescribed by a doctor which contain gelatin?

I understand that one of the main components of gelatin comes from the bones and skin of cows and that it is often imported from other countries. I also understand that it is highly unlikely that the standard processes involved in producing gelatin would ever remove or disable the BSE contamination.

It is also very alarming that BSE has a long incubation period (years) whereby the infected person has no symptoms. However, when symptoms do occur, the person dies a horrible death, via a deformed and shrinking brain, usually soon thereafter.

Since gelatin is used in so many food products, is it realistic to try avoiding all gelatin?

What are the mathematical chances of contracting the disease from gelatin in a food product?

Is there fewer gelatins in a standard hard pill as opposed to a "soft gel" capsule?

I feel the FDA, U.S. Government, and more importantly, the food and supplement industries, should do more to insure that all food products and supplements used in America are free from contamination of this horrible disease in order to prevent any chance of an outbreak like the one seen in Europe a few years ago.

I would appreciate your thoughts on this subject.
