Question: What’s the best prenatal nutrition?The things that sort of stick out to me are, you don't want to be Vitamin A deficient or Vitamin A toxic, so you're right in the middle of the range. You really don't want to be deficient in anything. Everyone knows about folic iron which is really important, but there's not really a good nutritional status test for choline. Biotin is very important. One third of mothers spontaneously become biotin deficient from pregnancy. And so I think that you want to be at least getting the RGA for biotin. DUS test of biotin status, is beta-hydroxyisovaleric acid, which is found on a blood panel but it is kind of pricey, but is the best. I think all of the nutrients are important, but I would single out those as being the most important to look at.
