It's difficult to say if you will experience nausea after taking vitamins.  Not everyone does, but here are a few tips to make them easier to stomach. • Take your vitamins with food; this enhances the body's ability to absorb the vitamins and decreases your risk of experiencing GI upset.   • Take divided doses; this will decrease the amount of vitamins and minerals going into your GI tract all at once, and can help to decrease the risk of stomach upset. • Take a liquid vitamin; By taking a liquid vitamin, you are lowering the amount of vitamins that immediately hit your bloodstream, therefore, reducing the potential risk of nausea. ESSENTIAL MULTI 3 IN 1 - MULTIVITAMIN WITH CALCIUMESSENTIAL MULTI 4 IN 1 - MULTIVITAMIN WITH CALCIUM
