St. John's Wort & Multivitamins: Potential Interactions & Safety

St John’s wort may affect how the liver breaks down some drugs, including multivitamins. Taking St John's wort with multivitamins can cause too much or too little of the vitamins to be absorbed by your body. Because of these possible interactions, it is recommended that you do not take St John’s wort with a multivitamin.
