Is 10, 000 iu vitamin a (as retinyl palmitate and 50% beta-carotene) too much for pregnant women? my bariatric multivitamin has that much. i'm worried.

Not too much: Pregnant women should take about 4000-6000 units of vit a in pregnancy but you have been only taking 5000 iu, as beta-carotene is not vitamin a but a benign precursor. Too little vit a can be as serious a problem as too much. It sounds like your level is fine. See http://www.Care2.Com/greenliving/is-vitamin-a-safe-for-pregnant-women.Html congratulations!
