Here's a really good article about it:ods.od.nih.gov/factsheets/VitaminA-HealthP
I learned something new today! Two types of Vitamin A exist - preformed (comes from animal products - meat, liver, dairy) and carotenoids (from plants). A reading of the above article would indicate that while you *can* overdo it on "preformed" Vitamin A, you can't really overdose on the Vitamin A that your body creates from plant pigments:
"Observational studies have suggested an association between high intakes of preformed vitamin A (more than 1,500 mcg daily—only slightly higher than the RDA), reduced bone mineral density, and increased fracture risk [1,4,37]. However, the results of studies on this risk have been mixed, so the safe retinol intake level for this association is unknown....
Unlike preformed vitamin A, beta-carotene is not known to be teratogenic or lead to reproductive toxicity . And even large supplemental doses (20–30 mg/day) of beta-carotene or diets with high levels of carotenoid-rich food for long periods are not associated with toxicity."
