I am pregnant and confused about the vitamin A limit. I know that 10,000 is upper limit however i am confused as to what that includes, both types of vitamin A or just Preformed? I have heard that the limit includes preformed,cartenoids but I have also heard that the limit only includes preformed and there is no limit for cartenoids from fruits and vegetables. The reason I ask is my prenatal has 5000IU (100 % beta carotene) and im wondering if that is included in the 10,000 IU limit? If so it seems extremely easy to go over 10,000 limit....anyone familiar with this subject
