Multi-Vitamins cause nausea, why?

You could find out the answer yourself by buying a selection of the individual vitamins that make up the multivitamin. Take each one seperately and see if you experience the nausea. If you don’t, you’ve eliminated one possibility (although see below). Be sure to match the dose too. After you’ve tried each one seperately, then move onto combinations of the indivdual vitamins.t.

Not a bad idea- but not really all that long- it’s likely to be B1, B2, or B3.

It is not Vit C.
