Rated 3 out of 5 by from 21st Sentry I wish this multi was more complete and more potent. It's not a bad product,but do find myself taking 2 on days when my diet isn't as great. I don't think this would be necessary if the potency was higher for some nutrients. A couple more ingredients that I'm used to in multi vit/min would be appreciated greatly and I'd believe the product was better. Overall, pretty average.
