You take a multivitamin as insurance, not treatment, and you have never once checked whether it contains a meaningful amount of anything. Most people find, when they finally turn the bottle around, that half the B vitamins are there in token amounts, present enough to print on the panel and small enough to do nothing.
The Daily Value was set as the amount that keeps a healthy adult out of deficiency. It was never meant to read as the target a supplement should aim for. Most multivitamins treat it as the finish line anyway. Hit 100 percent on the cheap vitamins, print the number, move on. Of the 41 labels we read, 29 park at least one B vitamin exactly at 100 percent, and biotin is the one they park there most often.
The pattern repeats on the antioxidant side. Vitamin C is the cheapest active in the category and it still lands at 60 to 90 mg on most panels, which is the floor again. Vitamin E sits at 90 to 100 percent. None of that is dangerous and none of it is wrong. It is just the minimum, sold as a complete formula, at a price that suggests otherwise.
Then there is what a multivitamin does not carry. Botanicals are the layer that separates a vitamin tablet from a daily foundation, and 34 of the 41 contain none at all. 12 are coated tablets with synthetic colorants, titanium dioxide or talc on the other-ingredients line. One formula of 41 cleared all four checks.
Taking a multivitamin and still stacking three more bottles? Read the percentages.If a panel shows 100 percent next to half its B vitamins and no botanicals anywhere, the second and third bottle in your cabinet are not an accident. They are the formula finishing itself at your expense. Look for the numbers that sit well past the floor, and for a botanical layer on the same label.
