the upper safe limit for vitamin a is 10 000 ius which you're already taking unless you're taking vitamin a for a specific medical reason recommended by your doctor. if not then you should not take more vitamin a on top of this. taking too much can be harmful can cause dizziness nausea headaches and can even cause very seriou side effects. beta carotene is also a form of vitamin a so again i would not take it if you're already taking 10 000 ius of vitamin a.
i take 10 000 iu of vitamin a palmitate. can ii also take a multi-vitamin w/ vitamin a beta carotene?
