Why Are So Many Indians Low on Vitamin B12?

A Look at Adult B12 Deficiency Across India
Have you ever felt constant fatigue, memory fog, or tingling in your hands and feet? You might blame stress or aging — but there’s a silent culprit behind these symptoms for millions of Indians: Vitamin deficiency.
It’s more common than you think — especially in Indian adults. In fact, over half of India’s adult population is believed to be deficient in Vitamin, according to multiple studies. But which states are the worst affected? And why is this even happening in the first place?
Let’s break it down.
What Is Vitamin B12 and Why Does It Matter?
Vitamin B12 (also called cobalamin) is crucial for:
- Making red blood cells
- Supporting brain and nerve health
- Boosting energy and metabolism
But here’s the catch: your body can’t make it on its own. You need to get it from food — primarily animal sources like dairy, eggs, fish, and meat.
So for vegetarians, vegans, or even those with poor absorption, deficiency becomes a real risk.
How Common Is B12 Deficiency in India?
India has one of the highest rates of B12 deficiency in the world, especially among adults.
A systematic review published in the Journal of Nutritional Science estimates that around 53% of Indian adults are deficient.
In cities, the numbers are still alarming. A recent corporate health survey in India found:
- 57% of working men had B12 deficiency
- Nearly 50% of women were also low in B12
The problem isn’t just in rural areas or low-income groups — it cuts across class, gender, and geography.
Which States Have the Worst Deficiency?
Here’s where it gets tricky. While India has done multiple nutrition surveys, state-level data for adult deficiency is limited.
However, based on smaller studies and related data (mostly among adolescents and young adults), we can make a few observations:
1. Gujarat
- Some of the highest B12 deficiency rates recorded.
- A study found up to 47% of teenagers and 29% of preschoolers were deficient — and adult numbers are expected to be similar or worse.
- Strong cultural vegetarianism could be a major factor.
2. Punjab
- Around 32% of school-age children had B12 deficiency in a recent national survey.
- Despite being a dairy-consuming state, limited meat intake and poor nutrient absorption might play a role.
3. Maharashtra, Delhi, Karnataka
- Smaller city-based studies in Mumbai, Pune, Bengaluru, and Delhi report adult deficiency rates between 45–60%.
- Urban lifestyle, poor diet quality, and stress-related digestive issues are contributors.
4. Kerala & West Bengal
- Interestingly, these states show much lower deficiency rates in youth (1–3%).
- This may be due to better dietary diversity, awareness, and healthcare access.
So while national data paints a broad picture, Gujarat and Punjab stand out among states with potential high adult deficiency.
Why Are Indians So Deficient?
- Vegetarianism: Over 70% of Indians follow a vegetarian or semi-vegetarian diet.
- Low dairy/egg intake: Even among vegetarians, daily intake of milk, cheese, or eggs is often too low.
- Poor gut health: Many Indians suffer from gastritis, IBS, or acid-related issues — all of which affect absorption.
- Lack of awareness: Most people don’t realize symptoms like fatigue, mood swings, or mouth ulcers may be linked to B12.
What Can You Do?
- Get tested: Ask your doctor for a simple serum B12 test.
- Supplement smartly: If you're deficient, consider oral sprays, tablets, or in severe cases, injections.
- Eat B12-rich foods: Eggs, dairy, fish, meat — or fortified cereals if you’re vegetarian.
- Watch out for symptoms: Mouth ulcers, brain fog, tingling, and extreme tiredness are early red flags.
Final Thoughts
Vitamin B12 deficiency is a quiet but serious health issue in India — especially for adults. While Gujarat and Punjab may be more affected, no state is truly immune.
The good news? It’s completely reversible — if caught early and treated properly.
So don’t wait for the symptoms to get worse. Get tested, get informed, and take charge of your health.
