Although a multivitamin is not something that you "feel" a difference when taking, you can definitely notice when you stop taking orange triad. I mainly take orange triad for the great ingredient profile that controlled labs has put together for this multi. I have taken orange triad for a couple years now, and have no reason to change to any other multivitamin. The only negative thing that i could say on this product is that the suggested serving of 2 pills, 2 times a day seems excessive. That being said, i take the recommended servings on training days, and cut down to 3 pills once a day or 2 pills twice a day on non training days, and do not notice any negatives from doing so.
