Is it best to take daily multivitamin? heard that some vitamins can build up in body. is it harmful if have too much of a vitamin? is there any health risk in taking multivitamins? is it best to eat well and forget multivitamins?

Good question: Opinions vary and after asking this question for the last 25 years you will not get a definitive answer. With that said I think it is valid to take a multivitamin or supplement. At least I think it is worthwhile to take a "whole food" supplement. This has valid research behind it. https://thedocstu.blogspot.com/2013/12/supplements-telling-difference-between.html
