Can vitamin A cause birth defects?

Maybe. Here’s what I recommend to do with your vitamin A intake when you’re expecting, or expecting to maybe be expecting.

Transcripts make it easier to use the information. You may just prefer to read. But having transcripts and video or audio can massively increase your productivity. For example, you can listen while you are washing the dishes, commuting to work, or doing other menial tasks, getting familiar with the material and scanning for things you want to learn more about. Then you can come back and keyword-search the transcript for the exact things you want to master in more detail.

  1. Hi Chris – so do you no longer agree with the WAPF that 20,000 IU (cod liver oil) should be consumed per day during pregnancy? In your article you state “the preponderance of the evidence clearly favors the view that 20,000-25,000 IU of vitamin A during pregnancy is safe and may even reduce the risk of birth defects.” Just want to confirm if you no longer recommend this amount unless you know you’re deficient? Thanks in advance! Love your work!

  2. Hi Chris,
    Im currently pregnant, taking a high quality pre-natal multivitamin that includes 5,000IU/day (60% beta carotene and 40% retinyl palmitate), I also consume pastured dairy and grass fed meat. I would like to start adding liver in capsule form, but am unsure if this poses a risk of too much vitamin A. Most pregnant women take pre-natal vitamins, I’m yet to see ones that leave out the vitamin A. Do you recommend liver as an addition to prenatal vitamins? Is best to keep vit. A from multivitamin and liver supplement under 10,000IU, or lower if you consume dairy and meat?
    Thank You

  3. Hello,
    As a midwife I was especially interested in today’s podcast. Curious if you have come across research differentiating effects of synthetic Vitamin A found in supplements vs. that from whole food sources?
