Ultra Woman vitatmins from vitamin world

So I started taking these based on the good reviews they got, long and the short of it I was feeling burned out and lacking energy.

So I started taking these. The dose is 2 pills per day. I noticed my urine was like yellow florescent one day and googled it. Turns out its from the vitamins, which I figured.

So I decided to take one a day instead. I feel pretty good and although I'm still tired after a long day it's not quite as bad as before.

My question is about these vitamins and vitamins in general - why are the daily percentages for some well over 100% Some of them are in the thousands! anyone knowledgeable on the subject that wants to explain this to me? I don't want to overdose on anything here and would think if there was any danger of that the vitamins wouldn't put that much in but honestly its still a little concerning.

here is the label
