India’s Silent Vitamin B12 Deficiency Crisis: An Overlooked Public Health Challenge

Conclusion

India’s vitamin B12 deficiency crisis is not a niche medical issue but a widespread public health challenge affecting energy, cognition, and productivity across age groups. Its invisibility stems from gradual symptoms, cultural dietary norms, and limited awareness. Addressing it requires shifting perception—from normalising chronic fatigue to recognising it as a potential sign of deficiency.

With timely diagnosis, informed dietary choices, and appropriate supplementation, this silent crisis is both preventable and reversible. Recognising vitamin B12 deficiency as a national health concern is the first step toward restoring not just physical health, but the everyday vitality of millions.
