Is it safe to take one a day women's multivitamin in the evening and a super b-complex in the morning? or can i take them together?

Overdoing it: There seems to be a myth in human experience that 'more is better'. In medicine it is proven over and over and over again that in almost all instances more is dangerous, less effective and causes more problems. Taking two different vitamins is unnecessary and puts extra strain on your liver and such. I would advise picking one and sticking to it.
