I agree, but that's because there isn't a lot of research done on vitamins. Why would someone waste his/her time on vitamin research when he can spend that time working for Viagra and making a lot of money? Any research into these things takes some level of altruism, which many lack. The least we can do is not attack it until it is properly studied.
There was another study that showed the elderly taking vitamin E have an increased chance of death (JHU, I think). But here is the catch - vitamin E, like most vitamins, is not made of just one molecule. It consists of several types of tocopherols and tocotrienols. The artificial vitamin E that you buy consists of not only just ONE of the useful forms (tocopherol, which is far less potent anti-oxidant than tocotrienol), but it contains 50% junk that your body has no use for. That is because synthetic vitamin E is made of d,l-alpha-tocopherol. The body has no use for the levorotatory enantiomer, therefore it is junk. Yet the study at JHU used this synthetic form. How can we conclude vitamin E is inefficient or even harmful when we give the patients only 10% of vitamin E (missing alpha, beta, gamma, delta tocopherols and tocotrienols) of which 50% could be harmful (no studies on the effects of the levorotatory enantiomer)? It could be the L enantiomer to blame and without a proper control, you can't ascertain that.
My point is that things are not as simple. I have had a strong interest in supplements because I want to know, rather than let some vitamin sellers tell me what is good or bad for me. In my research I found that it is much more difficult to get the vitamins you need than just going to Rite Aid and buying one. You really have to get down to the molecular level, which the average person cannot do. That's why instead of banning all vitamins, I think doctors should take the more active approach and recommend that manufacturers call something vitamin E ONLY if it contains all eight forms and no useless enantiomers (otherwise the label must say "synthetic, 10% vitamin E", just like "10% juice"). We have a lot of work to do here.
As a side note, I did a small vitamin experiment myself. I fed huge amounts of vitamin A to identical rabbits (my sister's, but she didn't know). One of them got the synthetic vitamin A, the other the natural from fish oil (I made sure they both got the same IUs). After a week, the rabbit that was taking the synthetic one began to look sick and lost about 30% of its fur. The other rabbit? Healthy as a bull. Now sure, this is a small study with an insignificant P, but it still demonstrates something. I think there have also been studies in the poising by synthetic vitamin A for people who spend long time in the Arctic, but no such effects have been observed with natural A...
What are you trying to say here exactly? Why would the rabbit being fed the "huge amount" of "natural Vit A" not develop Vit A toxicity? Do you believe the only reason the other rabbit appeared ill was because of synthetic components?
