Vitamin D before, during, and after pregnancy =alternate name
The more vitamin D for mom, the more benefits for both of them
- The benefits to mom start about 2,000 IU daily average (2000 IU costs less than $15 per year)
- Substantial benefits proven for 4,000 IU taken during pregnancy (fewer complications, lower cost)
- Best benefits at 6,000 IU - this much is also needed if breast feeding without supplementing the infant
- Taking > 2,000 IU raises the cost, primarily due to cost of Cofactors.
- Pregnancy category listing has
918 items along with many category combinations - Vitamin D during pregnancy
- Healthy pregnancies need lots of vitamin D
- Ensure a healthy pregnancy and baby - take Vitamin D before conception

Pregnancy category listing has
918 items along with many category combinations Vitamin D during pregnancy
IU Cumulative Benefit Blood level Cofactors Calcium $*/month 200 Better bones for mom
with 600 mg of Calcium6 ng/ml increase Not needed No effect $0.10 400 Less Rickets (but not zero with 400 IU)
3X less adolescent Schizophrenia
Fewer child seizures20-30 ng/ml Not needed No effect $0.20 2000 2X More likely to get pregnant naturally/IVF
2X Fewer dental problems with pregnancy
8X less diabetes
4X fewer C-sections (>37 ng)
4X less preeclampsia (40 ng vs 10 ng)
5X less child asthma
2X fewer language problems age 542 ng/ml Desirable < 750 mg $1 4000 2X fewer pregnancy complications
2X fewer pre-term births49 ng/ml Should have
cofactors< 750 mg $3 6000 Probable: larger benefits for above items
Just enough D for breastfed infant
More maternal and infant weightShould have
cofactors< 750 mg $4
$* assumes- You buy fairly |low cost vitamin D and Cofactors (more expensive if liquid and/or vegan )
- Using a low cost size of vitamin D - such as 5,000 IU, as often as needed. (50,000 IU costs even less)
Example: 5000 IU every other day if you only want an average of 2500 IU - Test vitamin D levels of only those moms who are at high risk for being vitamin D deficient
$30 for a blood test about 6 weeks after starting vitamin D to check that high-risk mom is getting enough
Benefits which do not fit into the previous matrix
- Vaginosis during pregnancy 5X more likely if low vitamin D – Dec 2011
- Gestational Diabetes mostly treated with just 2 doses of 50,000 IU of vitamin D – RCT Dec 2013
- Might reduce Postpartum Depression IU not specified
- Menstruation 10 months earlier if low on vitamin D – Aug 2011
Healthy pregnancies need lots of vitamin D
Most were taking 2,000 to 7,000 IU daily for >50% of pregnancy

Infants
Finland had recommended a huge amount of vitamin D for the infant:
20X more than US standard - Wagner April 2010 slide 31
Fewer than 40% of infants got 400 IU of vitamin D, The amount recommended by American Academy of Pediatrics
A June 2010 study which includes the following graph, found that MANY children do not even get 200 IU
and NONE of the children got more than 480 IU
Note: When infant stops drinking vitamin D fortified milk, be sure to supplement with vitamin D - as most fruit juice is not fortified.

- "However, it’s important not to exceed the recommended daily intake during pregnancy, as higher doses of certain vitamins and minerals may be harmful to the fetus (e.g., iron, folic acid, zinc)"
- "These may encompass vitamins vitamin B1, vitamin B2, B3, vitamin B6, vitamin B12, C, D, E, and K, along with folic acid, iodine, magnesium, iron, copper, zinc, selenium, and sometimes additional components like omega-3."

High vitamin D levels associated with higher sperm motility and morphology
Extra vitamin D increases litter size in pigs and has a trend toward higher pregnancy rates

Placenta
The Placenta, an Afterthought No Longer New York Times Dec 2018
- "An ephemeral organ, long dismissed merely as afterbirth, increasingly is viewed as critical to understanding the health and course of pregnancy."
- "Ninety percent of the placenta is made up of cells not from the mother but from the fetus."
- "As the placental beachhead grows, its cells specialize to do the work of heart, lungs, liver and kidneys until the fetus can fend for itself. Groups of cells exchange oxygen for carbon dioxide; provide nutrients and hormones; protect the fetus from harmful stress, germs and chemicals; and remove waste"
- "Male fetuses typically are larger than females throughout gestation, but they also have higher rates of spontaneous abortions, stillbirth, premature birth and neurodevelopmental conditions."
Human Placenta Project
Previously had studied placenta after birth.
Now studying the placenta as early as 1st trimester - to detect and hopefully avoid problemsShort url = http://is.gd/dpregnancy
