Is it bad to take extra vitamins every day?

First of all I am 19 and am a male, and am asking this in particularly because of my young age.

I know what I’m doing isn’t necessary, but that’s not my question, my question is if this can be bad for me in anyway, short term AND long term..?

So, what I take every day is…one multi vitamin, 2 500mg of Vitamin C tablets (one in morning and one in evening), One Vitamin D3 tablet (5,000 I.U.), and One Vitamin B-Complex tablet…
