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). What do you think?

Many multi-vitamins seem to provide vast "overdoses". I found a three-a-day multi that does this. But I only take one a day so as to cut the dosage to a more reasonable level. A doctor told a friend of mine to take children's multi' so to help with this problem. I have no financial interest in any of these products.

I get a lot of good information from the Quett question and answer program . But I've never found anywhere where I can get information on vitamin intake and how to judge what you should take when you have kidney disease . I have a stage for chronic kidney disease which naturally takes much less of the bacteria etc. in my stomach . Does this affect the amount of supplements and vitamins that I take. ? I'm currently taking 50+ four women because I am 80 five years old . Hope you can answer this question for me thank you

A don't think ANYONE in the nutritional science arena would would ever indicate that 500 mg of vitamin C which is 833% DV is excessive. I also believe there is a difference between filling the nutritional deficiencies and optimal cellular health. I agree that in general one should not exceed the upper tolerable limit, but I disagree with the answer ConsumerLab has provided here to this question.
