I've been vegan for four years, and never really thought to take supplements. My diet is pretty limited most days, due to general laziness in the kitchen, but I always eat a selection of veg every day, depending on what I can find on my shelf in the communal kitchen. I never really have too much energy, my mind is a lot slower and not quite as good as it used to be at remembering things and working things out. Unfortunately, I'm a heavy drinker and smoker, which, according to some of the articles Korn has posted up here, can actually deplete B12 in the body. So of course I attributed the loss of energy and mental retardeness to the booze. I'm not completely naiive - I do think that plays a role - but I'm starting to wonder if I should get tested for vitamin deficiencies, particularly B12.
I just wanted to know what the general procedure is - is it just a blood sample? And how do you go about getting one? Do you just go to your GP and ask him/her for one, will (s)he take a sample there and then, or do you have to be refered to a specialist? Can they refuse to do a test/do you have to have symptoms of something going wrong?
Thanks =)
