Vitamin ‘D’ Deficiency
What is Vitamin D?
Vitamin D is a fat-soluble vitamin that plays a crucial role in bone health, immunity, and overall metabolism . It is unique because it can be synthesized by the body when the skin is exposed to sunlight .
- Prevalence : One in five Indians is Vitamin D deficient.
Health Impacts
- Causes musculoskeletal pain, fatigue, and weakened immunity .
- Leads to hip fractures , which cost ₹50,000 (public hospitals) to ₹2.5 lakh (private hospitals).
Economic Consequences
- Healthcare costs due to deficiency-related conditions.
- Productivity loss due to increased absenteeism and reduced efficiency.
- Potential GDP impact: ₹27,720 crore annually.
Sources of Vitamin D
Natural Sources:
- Sunlight (UVB rays trigger Vitamin D synthesis in the skin)
- Fatty fish (Salmon, Mackerel, Tuna)
- Egg yolks
- Cod liver oil
Fortified Foods:
- Fortified milk and dairy products
- Fortified cereals and orange juice
Government Initiatives
- Proposed Scheme : Vitamin D Kuposhan Mukt Bharat (aligned with Ayushman Bharat).
-
Possible strategies :
- Lowering costs of Vitamin D testing and treatment.
- Using ICMR-NIN’s ‘Diet and Biomarkers Survey (DABS-I)’ for targeted interventions.
- Fortification of wheat flour with Vitamin D (like Jordan’s model).
- Public-private partnerships for fortification and supplements.
Global Examples
- Jordan : National Wheat Flour Fortification with Vitamin D.
- Ethiopia : Partnership with GAIN to supply Vitamin D premixes to children.
Challenges in Implementation
- Awareness and accessibility issues.
- Financial burden on underprivileged sections.
- Coordination between Centre and States for effective execution.
Way Forward
- Multi-stakeholder collaboration (government, private sector, international organizations).
- Education and awareness campaigns using traditional and social media.
- Budget allocation for research in advanced fortification technologies.
Prelims Practice Questions

- Genetic factors
- All of the above
2. Which international initiative focuses on Vitamin D fortification?
- GAIN (Global Alliance for Improved Nutrition)
