 Do vitamins go bad after opening them?
One is GNC Womens ultra mega active(EXP march 2013), and the other is GNC buffered vitamin C(EXP: 2014). I purchased them sometime last year, i cant remember exactly what month, i think it was closer to march or april. I took them for a couple of days, but i am horrible at remembering pills. So i stopped taking them. I want to try and take them again, but are they still good when they have been opened and then sitting there sealed with a cover for 6 months. I dont want to get sick from taking them...
