Silent Epidemic: Alarming Vitamin D Deficiency Across India

A recent nationwide study by Metropolis Healthcare Limited highlights a concerning reality: nearly half of all Indians suffer from Vitamin D deficiency India. Specifically, 46.5 percent of individuals tested showed deficient levels, while an additional 26 percent had insufficient vitamin D. This widespread inadequacy underscores a significant public health challenge in the country. The comprehensive analysis involved over 22 lakh test results collected between 2019 and January 2025. It provides robust data on vitamin D status across various demographics and regions. Meanwhile, health experts emphasize the far-reaching impact of this deficiency on bone health, immunity, and overall well-being.

Prevalence of Vitamin D Deficiency in India

The study clearly indicates that Vitamin D deficiency India remains a major health concern. Geographically, South India recorded the highest deficiency rates at 51.6 percent. Notably, states like Kerala, Puducherry, and Tamil Nadu each reported levels exceeding the 50 percent mark. Central India followed closely with 48.1 percent deficiency. North India showed a deficiency rate of 44.9 percent. Conversely, West India, including Maharashtra, fared slightly better at 42.9 percent. The Northeast region reported the lowest deficiency at 36.9 percent. This trend is possibly due to outdoor lifestyles and diverse dietary habits in that area.

Encouragingly, the report also suggests a gradual national improvement. Deficiency levels declined from approximately 51 percent in 2019–20 to 43 percent in 2023–24. Despite this positive trajectory, medical professionals warn about continuous challenges. Factors like urbanization, reduced sun exposure, and suboptimal dietary practices continue to fuel vitamin D inadequacy across all regions. Therefore, continuous efforts are essential to sustain this improvement.

Factors Contributing to Vitamin D Deficiency

Several underlying factors contribute to the high prevalence of Vitamin D deficiency India. Modern urban lifestyles, characterized by increased indoor time and limited sun exposure, play a crucial role. For instance, pollution and the use of sunscreens can further block the necessary UV-B rays. These rays are required for vitamin D synthesis in the skin. Dietary habits also present a challenge. Many traditional Indian diets often lack sufficient vitamin D-rich foods. This is especially true for vegetarian and lacto-vegetarian options, which rarely include fatty fish or fortified dairy products. Consequently, individuals relying on these diets are at a higher risk.

Moreover, certain cultural practices, such as extensive body covering, can further limit sun exposure, especially among women in some regions. Age also impacts vitamin D levels. Teenagers, aged 13–18 years, registered the highest deficiency rate at 66.9 percent. This alarming statistic highlights a growing adolescent health concern. Furthermore, gender disparities have narrowed over time. Now, 46.9 percent of women and 45.8 percent of men demonstrate deficiency, reflecting increased awareness and access to diagnostics.

Addressing Vitamin D Deficiency India: Expert Insights

Surendran Chemmenkotil, Managing Director of Metropolis Healthcare, emphasized that vitamin D deficiency remains an “overlooked health challenge” in India. Its silent effects significantly impact bone health, immunity, and overall well-being. He advocates for data-driven insights and preventive diagnostics to empower individuals with early awareness and better health control. Similarly, Dr. Kirti Chadha, Chief Scientific and Innovation Officer, stressed the importance of testing calcium and parathyroid hormone levels. These should be tested alongside vitamin D. This comprehensive approach helps identify underlying causes more effectively.

Dr. Chadha further explained that vitamin D is vital for bone, muscle, and immune function. Its deficiency often goes unnoticed until symptoms like fatigue or recurrent illnesses appear. Therefore, a multi-pronged strategy is crucial to combat this widespread issue effectively. This involves awareness campaigns, nutritional interventions, and routine screening.

Frequently Asked Questions

Q1: What percentage of Indians are Vitamin D deficient?

A1: A recent study by Metropolis Healthcare Limited found that 46.5 percent of Indians tested are Vitamin D deficient, and another 26 percent have insufficient levels, totaling nearly three-quarters with suboptimal levels.
