Check Now80%+ of Pregnant Woman and Virtually
100% of African American Woman are Vitamin D Deficient

Vitamin D levels greater than 40 (as compared to the population average of 25 ng/ml) reduce the risk of BOTH mother’s pregnancy outcomes and baby’s health outcomes.

Achieving 40-60 ng/ml (100-150 nmol/L) blood serum levels:

  • 59% lower risk of preterm birth
  • 60% lower risk of preterm birth in twins
  • Virtually eliminates pre-eclampsia
  • Supplementing up to 6400 IU/day is safe and effective during pregnancy & lactation
  • Reduction in many conditions of pregnancy – Gestational diabetes, bacterial vaginosis, post-partum depression
  • Eliminates racial disparity – In the US the preterm birth rate among African American women is 1.5 times that of Caucasian women

Benefits to baby:

  • 70% lower prevalence of common cold
  • 66% lower prevalence ear infections
  • 62% lower prevalence lung inflation
  • Improved language development
  • Reduction in type 1 diabetes (in adulthood)

Our Protocol in ACTION!

A new standard of care for pregnant women should include:

  • Vitamin D testing at 3 time points during pregnancy
  • Maintain vitamin D blood levels of 40-60 ng/ml (100-150 nmol/L) 25(OH)D
  • Up to 10,000 IU/day is safe

Medical University of South Carolina Leads the Way

Starting last year, September 2015, the Medical University of South Carolina, under the direction of Dr. Roger Newman, has implemented GrassrootsHealth’s Protect our Children NOW! Campaign.

Every mother that comes to one of their clinics for treatment, thousands of mothers per year, has a 25(OH)D test during their first prenatal visit (typically 12-14 weeks gestation). After reviewing the results, their OB may recommend supplementation to increase vitamin D levels, usually starting with 5000 IU vitamin D / day (their average entry vitamin D level is 20 ng/ml or below). Vitamins are free to patients under the program, thanks to the sponsorship of Bio-Tech Pharmacal, Inc. The OBs continue to monitor blood levels to ensure > 40 ng/ml throughout the pregnancy, typically testing again at 24-28 weeks and again at 34 – 36 weeks.

Note: Before the project began, 80% of all their patients and 100% of their African American patients were below 40 ng/ml.

Education of all of their OBs, over 20 doctors and health care providers, has occurred through free online continuing medical education (CME) courses provided by GrassrootsHealth. Educating and bringing the whole staff at MUSC up to speed was an important part of the project, so that all of the staff could buy into the new standard of care.

Educational materials are also provided for the mothers to help them understand the importance of taking their supplements. An onsite project manager assists in the education and follow through of all aspects of the program with staff and patients.

Rickets is on the Rise

Children being taken away from parents by CPS – when vitamin D deficiency is to blame.

Because rickets had been so rare, many doctors practicing just ten years ago had never seen a case in person and today many still don’t recognize it when they do see it. There have been several cases where children have been pulled away from their families by child protective services (CPS) due to undiagnosed rickets. The children are brought into a medical facility for some treatment (sickness, disease) and broken bones or signs of healing bones are found and presumed to be a result of abuse. At this point CPS is contacted and sometimes the children taken away.

Recently Wagner consulted on such a case where twin 6 month old boys (and their 3 older brothers) were removed from their loving home because of a broken rib and threat of child abuse. The mother was severely vitamin D deficient during pregnancy, and after, and solely breast fed the twins. Vitamin D tests for the twins showed their levels to be < 10 ng/ml. After much work by Wagner and their lawyer the children are now back with their family – and hopefully the whole family is getting sun and supplementation.

Dr. John Cannell, of The Vitamin D Council, has also consulted on such cases. He describes two different, yet similar, cases on his web site.

“We have been aware of the vitamin D deficiency state in the vast majority of our Caucasian patients and almost all our Black patients for far too long. Now the evidence has accumulated of the high price we pay in terms of prematurity and other obstetrical complications from our failure to systemically address these deficiencies in maternal vitamin D levels. It is time to change, to get ahead of the curve.”
