Vitamin D Supplementation Whilst Pregnant
by Mrs. A
I wanted to chat with you about Vitamin D and pregnancy and hopefully this page will be useful to other expecting mothers to be who are confused about the facts regarding dosage and safety limits.
From what I understand the general advice for Vitamin D requirements are totally off. I was taking 6,000 IU's for a while and then 10,000 IU's the month I conceived. My current Vit D level is 86.8 nmol/L. On your pregnancy page you have 5,000-10,000IU's as a recommendation. The Weston A. Price guidelines recommend between 2,000-4,000IU's for pregnant and nursing women. Dr. Bruce Hollis in his incredibly informative video titled 'Vitamin D supplementation in pregnancy & breastfeeding - effectiveness and safety' recommends 4,000IU's for all pregnant women.
My question is, I am comfortable with taking mega doses short term to get my serum levels up and then reducing to whatever dose can maintain a serum level of between 175-250 nmol/L (thank you for the suggestion!). Now that I am pregnant, how safe is it to do this? Is Vitamin D (like progesterone) harmless for baby if mom is taking very high amounts? I know there is a lot of misinformation surrounding Vitamin A (Weston A. Price say 20,000IU's for pregnant/nursing women totaling around 50,000IU's after you add the foods recommended) and the government says no more than 10,000IU's to be safe). Do you have a Vitamin A recommendation based on your research too. I took this from the Weston A. Price site:
"A 1999 study carried out in Rome, Italy found no congenital malformations among 120 infants whose mothers consumed an average of 50,000 IU of vitamin A per day.7 Some participants consumed up to 300,000 IU vitamin A daily during pregnancy with no birth defects in the offspring. An average of 50,000 IU vitamin A per day is consistent with our recommendation of cod liver oil to supply 20,000 IU per day plus additional vitamin A in liver, butter, seafood and egg yolks."
Thank you very much!!
