Deficiency in India

Vitamin D deficiency is extremely common in India despite abundant sunlight, due to dark skin, indoor lifestyles, and clothing coverage.

Testing and supplementation

A 25-OH vitamin D level test is the standard measure. Doses should be individualised by a doctor based on the level.
