I stopped taking One Source when I read about vitamin A and beta carotene, no point in taking chances right
!! I am taking Spring Valley Prenatal from walmart, costs about $5 has vitamin A 100% beta carotene and i do pretty well with this one. My doctor offered me the prescription prenatal and i loved it but not when i found out that my co pay for just a vitamin was $30!!!!!!!!! So I'll stick to my walmart brand! LOL!!
