This is anecdotal of course; I've been vegan for 20 years and have never taken supplements. I'm skinny, but my bone density and concentration are fine.

I've never had a cavity in my life. I'm not super old yet, but I don't think I have any joint issues beyond what comes with being nearly 50.

The efficacy of supplements isn't even established as reliable in many cases.

Porpiosly's comments on this seem quite extreme. I suggest others reading this do their own research or consult with their personal physicians before altering their diet in a significant way.
