Vitamin D Deficiency in Indian Women: Why Seventy to Ninety Percent of Us Are Low, What to Test, and How to Treat It
One of the most counter intuitive facts in Indian medicine is that despite living in a sunlight abundant country, between seventy and ninety percent of Indian adults are vitamin D deficient. The Indian Council of Medical Research and multiple regional studies from AIIMS, PGI Chandigarh, CMC Vellore and large private lab datasets consistently show that the average Indian woman has a twenty five hydroxy vitamin D level well below the sufficient range, and many are in the deficient band. Vitamin D is not just a bone vitamin — it is a hormone that regulates calcium absorption, immune balance, mood, ovarian function, fertility, pregnancy outcomes, postpartum mood, menopause bone strength and muscle power. For women across the reproductive life span and into menopause, low vitamin D is one of the most under recognised and most easily treatable contributors to vague fatigue, joint pain, recurrent infections, hair fall, low mood and poor pregnancy outcomes. This guide explains why so many Indians are deficient despite the sun, why it matters more for women, how the symptoms look in everyday life, how the lab test is interpreted, what treatment actually works in the Indian setting at every price point, and how to pair it with calcium for real bone strength.
