Since B vitamins are water soluble and stay in your body a short time, you might want to take a low dose B complex 2 or 3 times a day rather than a high dose on once a day.
Is there a vitamin B panel which labs can do? I know you can check B12 and folate, but is there a test for the others? That would give a better idea of what I actually need. B6 is the main one I'm suspicious about, since it's related to hair loss and dry skin on the sites I read. Almost a month into using B12 and my hair is still falling out in handfuls whenever I shampoo. So I'm still missing something. Or maybe I'm expecting too much too fast.
As far as safety, if I simply add in a B complex, other than Freddds paradoxical folate deficiency, is there anything to watch out for, or are they pretty non-toxic?
