VitaminFilter: I am a reasonably healthy male in my twenties, and I take a regular old Centrum multivitamin every day. My current huge container is almost empty, and before I buy another one, I'm wondering if there's something better. Is there really any difference between the various brands of multivitamins? Is there a brand better suited for someone my age? I have access to Whole Foods, Wild Oats, Trader Joes, etc., if that helps.

Does anyone have any experience with "greens plus"? Is it a waste of money, or can one really absorb 7 servings of vegetables with three tablespoons of powder? Google seems to be biased as to that question, and I haven't seen it mentioned in any of the other health and nutrition questions on here. Help?
