Hollis and Wagner are the experts on vitamin D in pregnancy.
They found that women around Charleston required levels above 40ng/ml 100nmol/l were needed to meet the mothers needs during pregnancy but in order to supply vitamin d replete milk 25(OH)D levels around the 60ng/ml level was required. Around latitude 32 N that took the mothers they tested around 6400iu/daily so further north it's likely to be higher.
Thanks for the information
My wife is 4 months pregnant and taking a prenatal vitamin right now. Not sure I want her to take any other supplements and since the best source of Vitamin D is the fun I'll talk her into getting into the sun more often hopefully.
SIR,-Dr. L. J. Harris is to be congratulated on his admirable
survey (Nov. 1, p. 681) of the present state of our knowledge as
to vitamins. I venture, however, to question the accuracy of
one of his statements: ' For nursing and expectant mothers
1,000-2,000 i.u. [vitamin D] daily may be prescribed.1.."I
made a search of the literature on this subject about a year ago;
I found only vague and contradictory statements. The following two quotations from recent authoritative textbooks are
typical: McCune' states that during pregnancy " an amount of
vitamin D equal to that contained in 5 teaspoonfuls of cod-liver
oil-that is, 1,700 i.u.-may be required in addition to a high
calcium intake to prevent a negative balance and guarantee
calcium retention." Shohl2 writes: " 400 units of vitamin D and
1 quart of milk daily should be included in the diet of pregnant
women." No experimental evidence is brought forward in
support of either of these statements.
I have recently completed a four-year survey of normal
pregnancy in the out-patient department of the City of London
Maternity Hospital. Some of the biochemical findings have
been published.3 They cover 226 48-hour calcium and phosphorus balances at various stages of pregnancy. They would
seem to show that doses of vitamin D smaller than 10,000 i.u.
per day have no influence whatever on calcium and phosphorus
metabolism and that doses considerably larger than this (up to
36,000 units per day) exert a definite influence only if the
calcium intake is above 1.5 g. per day in the early months and
later 2 g.
This subject is a difficult and complex one. My findings, to
be conclusive, must be confirmed on a larger number of cases.
But this is not a matter of purely academic interest. It concerns
us all-vitaily. Until further experimental evidence, adequate
and incontrovertible, is made available, I submit that we should
play for safety. In a climate like that of England every
pregnant woman should be given a supplement of vitamin D in
doses of not less than 10,000 i.u. per day in the first 7 months,
and 20,000 i.u. during the 8th and 9th months.-I am, etc.,

I don't understand you or what you are saying. Don't you understand the importance of vitamin D in absolutely every aspect of you body and that of your baby. Denying adequate vitamin D status at any point is bad enough but in the vital first few weeks seems particularly gross to me.

And you know I am deficient in vitamin D how, exactly? It is in my prenatals that I am taking, and I get out in the sun as much as possible. I would love to know your technique for knowing what someone is or isn't getting in their body based on seeing them on a message board. I have one perfectly healthy, smart, happy child already. Same prenatal vitamins with him, and my health is the most important thing to me during pregnancy. So your opinion that I am somehow harming my child is incorrect.
My vitamin D levels are fine, as I supplemented before pregnancy to get them to a good level. I prefer to avoid putting high amounts of anything into my body during the first 12 weeks of pregnancy. My midwife agrees that this is the best choice. But, thanks for your completely unnecessary opinion on my health, random man I've never met before!

Many suggestions are given by very knowledgeable folks here, and I appreciate all of them. However, I agree with you because my first and foremost advice to anyone, it to follow your heart when it comes to your health and the health of those in your family. If you're not comfortable with a recommedation, then don't follow it. You can always consider it in a future situation if desired.
Interesting! I will probably start vitamin D again after 12 weeks. I'm trying to be as careful as possible in the first trimester.
I think you are making a wise choice your first 12 weeks. If anything walking 30 minutes a day in the sun along with your prenatal vitamins in my opinion are enough. You can also eat foods high in vitamin D, but I agree with you that I would personally stay away from an additional supplement especially the first trimester.

This time of year in the northern hemisphere MOST people are vitamin D deficient or insufficient therefore the sooner the vitamin D deficiency is corrected the less damage will occur. Leaving vitamin D repletion to the later stages of pregnancy is far too late.
Anyone who thinks that food provides a useful amount of vitamin D is frankly ignorant of the amounts of vitamin D required for healthy living.
Food can only, at best, provide 10% of daily needs.
Similarly walking in the midday sun will be helpful but most people ONLY exposure less than 20% of skin surface and that is the same skin that is exposured throughout the day.
Vitamin D will only be created around midday so the rest of the day that newly minted vitamin d is being degraded/processed, by UVA, on into suprasterols the body doesn't use.
If you want to make vitamin d from sunshine you need to expose ALL your skin surface to UVB and then COVER THAT SKIN to protect the vitamin d and allow time for it to be absorbed into the body.
Only avoid vitamin d in the first semester is your aim is to ensure the maximum harm to the new baby occurs.
Remember the work Wagner did with 4000iu during pregnancy was done at Charleston latitude 32N if you live further north than Charleston you will probably require more vitamin d as less will come from sunshine.

And you expect women to take your advice over that of a midwife, trained in prenatal care?
If not taking extremely high doses of vitamin d was so harmful then I assume most babies would be unwell at birth. To act like not taking your advice is going to do irreversible damage is silly. Ultimately I run everything by my midwife and make the choice I feel is best for my child. If those choices were in any way harmful, I think I would've seen that by this point with my three year old.
I will stick with what I feel comfortable with at this point, prenatals, Probiotics, and fish oil, with healthy eating. Women's bodies are designed to nurture babies and I have no doubt in my body's ability to do so.
BECAUSE you are most likely like everyone else. ALL the most recent research finds that MOST people have LOW vitamin D status and the standard that they are regarding as sufficient are much lower than is safe or sensible. NATURALLY if humans lived outdoor lives wear little if any clothing we would attain and maintain levels around 60ng/ml Most people these days have level around 15~25ng/ml and only if they use an EFFECTIVE STRENGTH vitamin D of around 5000iu daily will levels be the natural levels human DNA evolved to work best with.

Exactly YOU are doing what most people do. So why do you think you will be any different from most people. The fact you call yourself BIPOLARMUM is a hint you suffer from depression and thus suffer chronic inflammation in the brain and thus use up your vitamin D faster than most people.
Quote:

absolutely not you simply have to apply common sense. As most people are vitamin D insufficient it is only the exceptional people who are vitamin D replete therefore it is safer to assume people are insufficient than they are vitamin D replete.

The trouble is our standards of what is a happy healthy child have changed over the years. We now accept that children are born with flat heads, require dental treatment, and will get asthma ALL these are signs their mother was Vitamin D deficient and they didn't get sufficient vitamin D in their early years.
Quote:

Well it's not problem getting a 25(OH)D and proving the fact. I doubt you are right I doubt your level is anything like 50ng/ml 125nmol/l There is not much point in arguing with people who won't listen to the most recent science and think they know it all.
Quote:

BUT the amounts we are talking about are less than a quarter of the amount your skin surface would naturally create if given the chance. Why do you think a quarter of the amount you DNA thinks is appropriate is adequate.
Why do you think you know better than your DNA?
Quote:
My midwife agrees that this is the best choice
But the fact is that health professionals have been wrong for the last 50 years and haven't changed their minds despite the fact that all the research shows that the current amounts in prenatal vitamins keep people vitamin D deficient.
Show me the research that proves the amount of vitamin d in prenatal vitamins raises status to the amount human DNA functions best with and I'll believe you but that evidence isn'tavailable.
Quote:

You don't have to believe me. Just get yourself a 25(OH)D TEST and you'll find out what I am saying is nothing but the truth.
Take 5000iu daily as soon as you can for 3 months test again and you'll see for yourself how your midwife needs re-education.
Get real.
And you expect women to take your advice over that of a midwife, trained in prenatal care?
Yes If you aren't interested in correcting the vitamin/mineral deficiency states that underlie most chronic conditions I don't see why you are posting on an alternative medicine website. Antibiotic Prescribing for Children, BCBSM, 2009
Why on earth do all these kids need so many antibiotics if they are not vitamin D deficient?
Why do we not understand the damage that antibiotics cause to immune function?
We know that farmers use antibiotics to fatten their lifestock, Do you want your children to become obese in later life because they were pumped full of antibiotics while children.
Health professionals keep people vitamin D deficient so they are dependent on medical services. If you raised your vitamin D levels to the natural levels human DNA evolved to function best with you could reduce your medicine usage. I don't take any pharmaceuticals now and I have a bipolar diagnosis.
