I've been taking a Daily Advantage multi but am now concerned by the very high % DV for vitamin C (833% DV), niacin (325% DV), and B vitamins (over 1,000% DV for several). The company tells me this formula is based on clinical experience and the scientific literature. What do you think?
Unless you are deficient in each of these vitamins you don't need to take such high doses of each. Some may being doing more harm than good. It's good that you are now studying the ingredients listed on the label. You may still benefit from a multivitamin, but one which is likely to fill your nutritional gaps without exceeding upper tolerable intake levels.
