Believe me, not all doctors think the same. They may be taught the same concepts but they have their own ways of doing things when it comes to "what to give to the patient" (I am sure your GP will acknowledge this)
Taking supplement is ok, but prolonged intake isn't, since the adverse effects are induced by an accumulative process.
So avoid supplementations if you can, don't take it unless you really need to.
And also, It's important to remember that a vegan, needs other supplementations other than vitamin tablets e.g. essential amino acids.
...and there are plenty more on the list.
Anyway, thats me, I prefer to obtain my nutrients from natural food products rather than from processed forms.

So what are the side effects of taking vitamins? And don't you think the FDA would actually restrict vitamins if they were that bad for you? I've also read a nutritionist who recommended taking vitamins, he was a doctor who researched a vegetarian diet that helps with depression. I don't have depression myself, though.
Amino acids are easily obtained from other foods. Legumes, beans, soy products, etc.
I can get all the things you can from meat without eating meat. With the environmental, health, and moral issues of eating meat I consider this diet superior to omnivorous diets.
