Deficiency of vitamin D has become a global public health issue. Many people, for many reasons, are not getting enough vitamin D. According to Harvard University, an estimated 1 billion people worldwide are vitamin D deficient. It can be found in all age groups and Ethnicities. Deficiency of vitamin D can have short as well as long term affects and could lead to numerous diseases like skeletal diseases, metabolic disorders, cancer, cardiovascular disease, autoimmune diseases, infections, cognitive disorders, and/or mortality and also rickets and Osteomalacia.
Amount of vitamin D required by people each day is still in question among scientist. A report was released in which tripling the daily vitamin D intake is recommended for children and adults in the U.S. and Canada. There are some foods that are rich in vitamin D. Many people also take supplements for vitamin D but the level in most multivitamins is 400 IU which is too low.
