I eat my vitamins.
I don't supplement, but I track what I eat with Fitday, and if I'm missing a vitamin or three I adjust my eating. When I'm "on" I can, and do, get nearly 100% or better of all my vitamins and minerals from food, and yes, while eating restricted calories. It does take a not inconsiderable amount of thought, research and planning, but I think that vitamins from food are more useful than vitamins from, well, vitamins, so if I can, I do. You can too!
