Tag: Upset stomach from vitamins

According to the Centers for Disease Control and Prevention, more than one-third of American adults take a multivitamin, but for some, the health-conscious habit leads to an unexpected side effect: feeling upset. The reasons behind feeling unwell after taking vitamins can range from simple digestive issues to ingredient sensitivities or even interactions with medications.

Research from 2017 shows that while many people take multivitamins without issues, some do experience nausea and other gastrointestinal symptoms. This raises the common question: can taking vitamin supplements make you feel sick? The answer is yes, and the reasons range from timing and dosage to specific nutrient sensitivities.
