multi vitamins

I'm concerned with the amount of vitamins I am getting with my diet I do work and travel a lot so I meet with people at restaurants and I don't feel like my nutrition is going to be as good as it should be. Which multivitamin would you suggest to get things going in the right direction and cover...

I read that multi vitamins don’t do much of anything in the body because whatever you take just gets pushed through and isn’t absorbed. How much of that is true? When I take them I noticed my urine turns weird colors like orange so I’m assuming that is them being expelled by the body
