Indian Council of Medical Research recommends a daily supplement of 400 IU/day (international units of measurement) of Vitamin D for Indians under situations of minimal exposure to sunlight.
According to a recent study, despite India being a tropical country with an abundance of sunlight, 76 percent of Indians have Vitamin D deficiency and insufficiency, especially in the age group of 18-30 years.
Limited sunlight exposure, air pollution obstructing UVB rays, high melanin levels, and low intake of fortified foods are some of the major causes of Vitamin D deficiency.
