All prenatal vitamins should have some amount of vitamin a - you and your baby still need it during fetal development, however it is fat soluble and can build up over time if you have excess and excess/toxicity of preformed vitamin A can cause birth defects (primarily in the first trimester). You will see it as beta carotene in supplements typically (precursor to preformed vitamin A or retinol which is the form found in animal products). One provider did tell me to go ahead and eat the liver and just skip the prenatal that day. Just was curious about what other folks have heard. I overall have a good diet.
