Can vitamins make you tired?

I was going to the gym fine and I realized my energy level had gone through the roof. By Tuesday, I remembered that I haven’t been taking my vitamins.
Even though I was feeling well and eating well, I figured it couldn’t hurt to get some extra vitamins. Especially since my hair has been suffering from all the sweating I’ve been doing.
Shortly after taking the vitamins I started to feel tired. I just figured the workouts were catching up with me and maybe I needed to take 2 days off.
Well its Thursday now and I’ve been taking my multivitamins every day and I’m exhausted. I don’t have the energy to hit the gym.
It got me wondering if my vitamins had something to do with it since I seem to need a nap after taking them. When I started my exercising I noticed I seem to lack energy after I would work out. I would take my vitamins after the work out. Then I’ve forgotten to take any for a few days and my energy was ridiculous. I had a hard time staying still.
I looked it up and found where several people feel that their vitamins also make them tired.
Does anyone in fluther know if vitamins can make your tired and if so, which ones? Also why would they make a person tired?
