Vitamin D: Busting myths and pregnancy support

Not only was Dr. Michael Holick the first to isolate and identify the active form of vitamin D, but he also played a key role in developing a vitamin D treatment for various conditions including metabolic disease in infants and children as well as patients who were wheelchair bound due to kidney disease.

In this interview, Dr. Holick shares his clinical observations, the connection between vitamin D and calcium and how this translates to the recommendations for various age groups. Dr. Holick will cover why it’s so important for pregnant mothers or breastfeeding mothers to ensure adequate levels of vitamin D and how it translates to the fetus/ baby. Plus, Dr. Holick busts the myth of “you can just get vitamin D from going outside.”
