I started taking vitamins about 1 month ago-B-stress vitamin-Co enzyme 10 -selenium. Since then my blood pressure was much higher than usual 110/70 after taking vitamins 150/93. I stopped the vitamins and now my blood pressure is back to normal. I'm wondering if the vitamins interfere with the absorption of my BP pills 30 mg of prinivil and 5 mg of norvasc. Mickey99
