Having a deficiency in vitamins, or too much...Worse?

Well, I am just wondering. Is it worst having too much of the daily value for vitamins, or having a deficiency?

I know some vitamins are water soluble vitamins and can be taken more than the daily value for... like vitamin C, I take a vitamin C supplement that's like 330 % of the daily value, lol.

.. what vitamins are dangerous to get too much of?

I had a cup of pumpkin puree with breakfast and it had a lot of vitamin A in it, so.... I skipped my multi vitamin for today because it already had a lot of vitamin A in it. Not sure if it's bad to have too much vitamin A. But, I took a vitamin C and a B vitamin supplement.

If you're worried just make an appointment to see your doctor. They can order blood tests to track levels of certain vitamins (like Vitamin D). They might have a better answer for you. I frequently go waaaay over in Vitamin A because of my love for baby spinach and butternut squash but I've read that Vitamin A from plant sources is different than Vitamin A from animal sources or vitamins--both of which can be quite toxic. I did read that too much Vitamin A from plant sources (beta carotene) can make you turn orange though! Since I'm not a doctor and anyone can post on the internet---I plan to raise this same question with my doctor. It's a good question!

i know too much potassium is bad and can lead to a heart attack and seizures. i think too much iron is bad too.
