People in India are deficient in Vitamin D despite ample sunlight. The Rajya Sabha was informed that this is leading to problems like weaker bones among the population.

The prevalence of Vitamin D deficiency is in the range of 10 percent to 90 percent across all age groups, he said.
The synthesis of Vitamin D in the body is dependent on multiple factors like duration and time of exposure to sunlight, latitude, atmospheric pollution and skin pigmentation.
The studies have also shown that the Vitamin D deficiency may be associated with low bone mineral density, leading to weaker bones and fracture risk, Azad said.
