Every mother wants her baby to be in good health and according to a new study, Vitamin D could just be the right supplement. It is during the last stages of pregnancy when the bones of the baby strengthen. Studies found that babies born during winter had greater bone mass than those in summer because women tend to receive Vitamin D from sunlight in the summer which gradually drops in winter. Hence, it was effectively proved that consuming Vitamin D during pregnancy can help strengthen the bones of babies born in winter.
