She lists constipation, diarrhea, upset abdomen, and nausea as the commonest multivitamin negative effects.
This may occur when somebody will get an excessive amount of of a sure nutrient, or is allergic to a selected ingredient. Vitamin C, for instance, can irritate the abdomen lining, and iron could cause constipation and bloating when your physique can’t take up it, explains Wahlstedt.

Moreover, nutritional vitamins and dietary supplements can work together together with your physique and different medicines greater than you may assume. “Since so many multivitamins are additionally now including in ‘particular’ elements like herbs and adaptogens, I all the time suggest talking with a physician or dietitian earlier than initiating to verify it doesn’t work together with every other medicines and and is acceptable on your well being context,” Wahlstedt says.

- An excessive amount of vitamin A: complications, stomach ache, vomiting, blurry imaginative and prescient, and adjustments to the pores and skin, hair, and nails

Additional, some usually tend to trigger injury than others. “Particularly, vitamin A or iron might be significantly hazardous when taken at increased ranges than suggested on their bottle labels,” Dr. Purdy says.

Alongside these strains, needless to say getting nutritional vitamins and minerals from pure sources, like meals, is handiest. With, say, getting extra vitamin D, this might appear like consuming mushrooms, egg yolks, and fatty fish, in addition to getting out within the solar for 5 to 10 minutes a pair occasions every week.
If that’s not doable for you, that’s okay! Multivitamins may help—if taken appropriately. “For optimum efficacy and security functions, choose top quality merchandise from dependable suppliers,” Dr. Purdy says.
However what do you do for those who want that multivitamin nevertheless it’s inflicting your physique digestive misery or an allergic response?

Your main care physician or dietitian can speak you thru the most suitable choice for you.
