I have tried different brands of multi-vitamins; Centrum, GNC's "Mega-Man" vitamins, even generic Multi-Vitamins.....some are very expensive and some are dirt cheap. I do eat well, I eat my veggies and try to eat balanced meals- but I want to find out whatt is worth the money for vitamins. I haven't found much on the internet about this....can anyone help me with this? Is it worth spending $25.00 a bottle at GNC? I would love to know what others know about this.
