Vitamin D is sometimes referred to as a hormone because the activated forms are hormones. You utilize this essential vitamin in nearly all parts of your body. Vitamin D is crucial for absorbing other nutrients like calcium, iron, magnesium, phosphate, and zinc. Vitamin D also regulates immune function, cell growth, neuromuscular function and affects thousands of genes. Your baby relies on you to supply adequate vitamin D to support their growth and development during pregnancy. Despite the importance of vitamin D, data shows that most pregnant mothers do not get enough vitamin D. Deficiency is associated with elevated risks for preeclampsia, adverse health outcomes for your child later in life, and even a cesarean section. Most prenatal vitamins contain far less vitamin D than the evidence suggests during pregnancy. Find out what the current evidence says about vitamin D during pregnancy and how to ensure you have optimal vitamin D levels to support you and your baby.
