I take 4 vitamins a day (2 multi & 2 hair and nail), 4 fiber supplements and 2 omega 3 supplements for dry eye. Is there a danger for me taking them?

No hazard unless... Most vitamins are non-toxic at any level. It is possible to get toxic from too much A, D, E, B6, Iron & Zinc, but one has to take massive doses, much higher than would be present in the vitamins you are taking. The only reason for caution is many vits have hazardous synthetic E (dl-alpha tochopehol) instead of natural E (d-alpha toc.) & many have toxic additives. See http://tinyurl.com/mzrkbx8.
