Hi. does taking multivitamins cause nausea and fatigue? i noticed that after taking them for more than 2 weeks now.

Some: Some MV preps have ingredients which may do that.....particularly Iron. Some bulking and coloring agent might be causing the intolerance.

Its possible: Nausea YES ...some people do not tolerate B vitamins (included in Multivitamins) Try taking on a full stomach! Fatigue is NOT related and is probably why you are taking the vitamins in the first place. The fatigue should be evaluated as a medical problem NOT a "side effect" Hope this helps Dr Z

It can: Some vitamins can cause nausea, but fatigue would be unusual.
