4000 IU Vitamin D Daily Cuts Preterm Birth Risk in Half

A new study by researchers from Medical University of South Carolina has found that women taking 4000 IU of vitamin D daily during pregnancy cut their chances of a preterm birth in half compared to women taking only 200-400 IU.  The women taking 4000 IU of vitamin D also has a reduced risk of infections.  There were no adverse effects found for this level of supplementation.  

If you think you live in a sunny environment and don't need vitamin D, consider this:
"All the women taking part in the study were living in Charleston — in sunny South Carolina. Overall, 85 per cent were either insufficient, or "frankly deficient" in vitamin D when the study began."

This adds to the list of studies indicating that the vast majority of urbanites are deficient even if they live in sunny places.

Psst... the link is broken.

Tuck,

Thanks, I fixed it.

Do you think fermented cod liver is enough? After my last baby was born I had low vitamin D and have since switched to all pastured animal products and the cod liver oil. I haven't been tested recently and am on a preconception diet of sorts. So do you think taking the 4000 IUs in addition to the cod liver oil is necessary?

Cool.

So for decades they were giving incorrect advice based on a poorly interpreted study and a bunch of assumptions.

Hmm... Sounds familiar.

I wonder if they took data on how much time they actually spent in the sun. Higher levels of UVB are useless if you don't spend any time in them except from behind glass. Plus you would need to be out there in an approx 4 or 5 hour window in the middle of the day. Otherwise, not enough UVB present to do much good. Most people's sun exposure consists of walking from the car to the store and back, and that is about it.

Mrs. S,
I take Fermented CLO, plus also supplement with 5000 IU vit D, almost every day. At my last blood test my level was 62. I know that the level in FLCO, 1/2 tsp, is 150% DV, which is 600 IU, (if 400 iu is still the DV). I am getting this right off my bottle, which also has the butter oil in it. It's best to get your levels tested, but I would think just the vit D from FCLO is not enough.
Just my 2 cents.
Good Luck!
Diana

Folks who live in Sunny locations, use far more sunscren on a regular bases then their neighbors north of them who only live in heat. Kind of a lose-lose I'd say

And what about this study saying that vitamin d3 supplements are harmful?

Rudolf,

That "study" is not a study but an opinion piece by Trevor Marshall. His opinion has no facts to support it, for more on that read this:

Don, thanks for pointing this out.

Thanks for sharing. I live in sunny AZ, spend a minimum of 90 minutes a day in the sun walking my dogs and up to 2 1/2 hrs. In addition to that I supplement with Carlson's D3 2000 iu's 5 days a week. I recently had my levels tested and to my great surprise, I was deficient. My level came in at 21. I was floored.

Subbing to get comments.. Thanks. I take the fermented clo/butter oil, and bought vitamin D drops but I have been wondering what to do.
