What Are The Most Common Vitamin Supplements?

Multivitamins

Multivitamins are supplements that contain many vitamins and minerals in a single pill. Since they contain more than one nutrient, multivitamins may increase the potential for drug interactions. Patients taking sulfa drugs, diuretics, antibiotics, antacids, or nonsteroidal anti-inflammatory medicines should always ask a physician or a pharmacist about whether a multivitamin is safe for their health. Pregnant women should also ask a doctor before using any type of multivitamin. Patients should never take more than one type of multivitamin without consulting a doctor, as this could lead to an overdose. Multivitamins need to be taken with a full glass of water, and they should be stored away from moisture and heat. Overdoses of vitamin A, D, E, and K are associated with serious side effects, including back pain, severe headache, vomiting, diarrhea, constipation, and blood in the urine. Patients who notice any worrying side effects or who believe they may have overdosed on a vitamin should contact a poison control center immediately or seek emergency medical care.
