Are you sure you're taking Vitamin A, or beta carotene yielding that much Vitamin A? Unless you have a specific reason to, it's not recommended to take Vitamin A as a supplement, as it's liver toxic if you take too much. But you can take all the beta carotene you want, and it will convert to as much Vitamin A as you need and flush the rest or use it for other purposes.
I don't think that the Vitamin A will hurt you, however, I would not add anymore.
btw, the krill oil that I'm taking contain 50 IU of vitamin A
