 Our project involves proving the power of optimizing prenatal supplements. During pregnancy, the levels of many vitamins and minerals decreases 20 to 50 percent, so prenatal supplements are needed for a healthy pregnancy. However, prenatal supplements vary widely in content and quality. Most prenatals average only 50 percent of the recommendations we developed with the Neurological Health Foundation. Prenatals can prevent many pregnancy problems if at an optimal dose, including miscarriage, anemia, and preterm birth. Optimal prenatal supplements can prevent many childhood disorders, including anemia, autism, and birth defect. Our proposed clinical trial will demonstrate the power of optimizing prenatal supplements to decrease the complications and pregnancies we estimate 20 to 40 percent and improving the health of children and their mothers worldwide.
