Researchers Determine Vitamin D Level Necessary to Help Reduce Preterm Births by 50%!
- According to the 2015 Save the Children report* on the health of mothers around the world, the U.S. ranks worst among developed countries.
- Shockingly, pregnant American women face a one in 1,800 risk of dying from pregnancy-related complications
— a 10 times higher risk than that of women in Poland and Austria, for example. - Researchers Call for Vitamin D Testing As Part of Standard of Care for Pregnant Women
Note: Vitamin D Life wants the standard of care to be Vitamin D SUPPLEMENTATION
