Optimal Vitamin D Supplementation During Pregnancy and Lactation:
4,000 IU During Pregnancy; 6,400 IU Per Day During Lactation
December 9, 2017

Vitamin D dosing recommendations during pregnancy and lactation continue to be confusing with studies clearly showing that higher potency supplementation ensures the healthiest baby, while the AMA (Australian Medical Association) erroneously dismisses the value of vitamin D supplementation during pregnancy, for both mothers and babies.

AMA's position was shown in an article on December 3rd in The New Daily, Australia's leading media, entitled, “No case for vitamin D pills in routine pregnancy: AMA president."

In this article AMA’s national president, Dr. Michael Gannon, said that there is no need to take supplements if vitamin D levels are normal. Poppycock!

The first error that he makes is based on an inadequate, deficient determination of what healthy "normal" vitamin D blood levels are. The blood vitamin D values that the AMA promotes as adequate are regarded by vitamin D scientists as being deficiency states.

The AMA says that a blood level of 11 ng/ml is sufficient. This low level allows at least double the risk in preterm birth.

When blood vitamin D is 40 mg/ml the risk of preterm birth can be 59% lower than when blood vitamin D is 20 ng/ml. Therefore, 11 ng/ml is critically inadequate.

There is a tremendous difference between the effects of 40 mg/ml and 11 mg/ml. Unless mothers regularly eat quality food sources of vitamin D and/or get adequate sunlight studies have shown that inadequate vitamin D blood levels are the norm for most people, with studies showing that 77% of Americans are deficient in vitamin D.1 2 This is an even more serious issue during pregnancy and lactation.



TWICE AS MANY FULL-TERM DELIVERIES

In a study that compared pregnant women that took 400 IU of vitamin D per day, 2,000 IU per day and 4,000 IU per day, mothers that took 4,000 IU per day experienced half the rate of pre-term delivery. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4365419/pdf/nihms-446512.pdf

To arrive at a blood level of 40 ng/ml a majority of people must supplement with 4,000 IU of vitamin D per day.

The AMA further said that vitamin D does not transfer from the mother to the baby during lactation.

This might be what is seen when the mother has a low vitamin D blood level to begin with, as small changes to an insignificantly small measurement are below the threshold level of detection.

However, studies show that there is an important improvement in baby’s vitamin D levels when a nursing mother’s vitamin D supplementation is high enough.

One study showed that 4,000 IU per day of maternal supplementation was not enough to improve the vitamin D blood level of a nursing baby. https://www.ncbi.nlm.nih.gov/pubmed/18290720

So, 4,000 IU of daily vitamin D supplementation can reduce the risk of preterm delivery by half, but still isn’t enough to improve the lactating baby’s vitamin D stores.

Fortunately, two more recent studies confirm that nursing mothers that take 6,400 IU of daily supplemental vitamin D during lactation produced optimal levels of vitamin D in their nursing infant, which the authors said was “the equivalent of giving the babies 800 IU/day.” https://www.ncbi.nlm.nih.gov/pubmed/17661565

This can significantly improve the chances that a baby will be gifted lifelong with a stronger immune response and healthier bones and teeth.

The highest potency of vitamin D in a one-daily multivitamin is 3,000 IU per daily tablet. This is provided by SuperNutrition's SimplyOne Prenatal, which is available on Amazon.com.This is exceptional when it is considered that two of the highest quality best-selling prenatal multivitamins from world leaders New Chapter and Garden of Life provide 1,000 IU and 600 IU of daily vitamin D. respectively.
