Most of the articles I've read suggest no proven link between taking vitamin supplements and longevity, disease prevention or just better overall health (even popular ones such as Vitamin D).
I've been taking a rather expensive "food based" multivitamin for the past 6 months or so. I do "feel good" about taking them but aside from that placebo effect I have not experienced a measurable improvement in health. I'd like to stop taking them, but before I do I thought I'd ask here for opinions.
Are vitamins a waste of time and money? (excluding doctor-prescribed cases where one has an inherent deficiency)
