When I took Women's One-A-Day multivitamin, I became light
headed and dizzy. At one moment I even fell forward because I
was about to pass out. My neighbor caught me (we have play
dates for our kids and we sit and chat). She is a nurse and
said that there might be an additive in it that I was having a
reaction to or perhaps their vitamin dosage was too high.
When I called the company, they said the same thing about
there being an additive. Though after research, I've found
that it is a symptom of overdose. I never took more than the
recommended dosage, however, some vitamins have very high amounts
in that compact little pill. If you are getting a full days
worth of vitamins via food, there isn't a reason to take a
multivitamin...that could possibly cause an overdose. Nausea
is also a symptom of overdose. :) Just drink some green
smoothies.
