Vitamin B12 Deficiency in Indian Vegetarians
Why it is the most common hidden gap — and what to do about it
Why Indian Vegetarians Are at Risk
Vitamin B12 is found almost exclusively in animal-derived foods — meat, fish, eggs. For Indian vegetarians who rely on dairy as their primary B12 source, intake often falls far below the ICMR-NIN recommended 2.2 µg/day. Studies show that up to 70–80% of Indian vegetarians may have suboptimal B12 levels.
Common Symptoms
- Persistent fatigue and weakness
- Numbness or tingling in hands and feet
- Difficulty concentrating or “brain fog”
- Pale or yellowish skin
- Mouth ulcers and sore tongue
- Mood changes, irritability, or low mood
- Balance problems
Many of these symptoms develop gradually and are often mistaken for stress, thyroid issues, or iron deficiency.
Indian Vegetarian Food Sources of B12
| Food | B12 per Serving | Notes |
|---|---|---|
| Curd (200 ml) | ~0.5–0.7 µg | Best daily source for vegetarians |
| Milk (200 ml) | ~0.4–0.5 µg | Pasteurised retains B12 |
| Paneer (100 g) | ~0.8–1.0 µg | Good source but calorie-dense |
| Cheese (30 g) | ~0.4 µg | Processed cheese has less |
| Fortified plant milk | ~0.8–1.2 µg | Check label for fortification |
| Fortified cereals | Varies | Not widely available in India |
The problem: Even with generous dairy intake, many vegetarians get only 0.6–1.5 µg/day against a target of 2.2 µg/day. That is a persistent 30–70% gap.
When to Consider a Supplement
Consult a doctor before supplementing. A simple blood test (serum B12 + homocysteine) can confirm deficiency. Your doctor may recommend methylcobalamin or cyanocobalamin supplements based on your levels. Self-supplementing without testing can mask other deficiencies.
How MyBioWell Helps
MyBioWell checks your B12 gap (along with 11 other nutrients) based on your actual food intake and ICMR-NIN targets. If your diet falls short, the AI suggests specific Indian foods to close the gap where possible, and flags when dietary sources alone are unlikely to be sufficient.
