The vitamin A that you need to be cautious of is animal derived vitamin a, (found in high does of food such as liver) rather than plant derived.

Plant derived vitamin A, through a multi vitamin or through food, is fine.

There have been recent studies where this definition has been clarified. If anyone wants the links, please let me know.

A quick quote from a recent study, if it helps put your mind at ease, is this:

Supplements that contain high levels of beta carotene should not pose a problem with respect to birth defects, nor should high levels of beta carotene in the diet.
HTH. I know it is confusing!
