Basically I take my B Complex vits as well as other Vitamins and Minerals with breakfast and within 10-15 mins (post breakfast), i visit toilet daily. I always thought that Vitamins have to go through your entire body first and only the food which has been processed through stomach (and after all essential nutrients have been absorbed by body/blood) ends up in the bowel but one of my friends told me that's not the case and i'm wasting my time and money if I go for poo within half hour of taking them. I always thought any excessive water-soluble vits or minerals get excreted through kidneys and bladder. Can someone please shed some light on this with evidence???
thanks in advance..
