What is Vitamin B12 and Why It Matters?
Vitamin B12, also called cobalamin, helps your body make red blood cells, keep your nerves healthy and produce DNA. It is found mainly in animal-based foods because certain bactaria makes it. This is why vegetarians and vegans have a higher risk of B12 deficiency than people who regularly eat meat, fish or eggs.
Why This Matters So Much in Indian Diets
India has one of the highest rates of vegetarianism in the world, and studies have repeatedly found that a large share of Indian vegetarians, even those who consume dairy, have suboptimal or deficient B12 levels. This is partly because dairy alone often isn’t consumed in quantities high enough to meet daily needs. Also, Partly because B12 deficiency can be subtle for years before symptoms like fatigue, brain fog, tingling in the hands and feet, or memory issues become noticeable. Doctors in India increasingly advise vegetarians to check their B12 levels regularly.
The Real Sources
- Dairy products like milk, curd, paneer, and cheese are the most reliable natural vegetarian sources of B12, though the amount varies and often isn’t enough on its own
- Eggs are a good source for lacto-ovo vegetarians who include them, offering meaningfully more B12 than dairy alone
- Fortified foods such as certain breakfast cereals, plant milks, and nutritional yeast are increasingly available in India and can help fill the gap
- B12 supplements, available as tablets or sublingual drops, are often the most reliable way for strict vegetarians and vegans to meet their daily requirement
- Fermented foods like idli and dosa batter were once thought to contribute meaningful B12 through fermentation, but current research suggests this contribution is unreliable and too small to depend on
The Real Benefits of Adequate B12
- Supports healthy nerve function and helps prevent tingling, numbness, or nerve damage over time
- Helps the body produce red blood cells, reducing the risk of megaloblastic anemia and constant fatigue
- Plays a role in DNA synthesis and cell division, which is especially important during pregnancy
- Supports cognitive function and may help protect against memory issues and brain fog linked to deficiency
- Helps maintain steady energy levels, since low B12 is a common and often overlooked cause of persistent tiredness
How To Make Sure You’re Getting Enough
- If you’re a strict vegetarian, vegan or over 50, you should get a vitamin B12 test done once a year. Vitamin B12 absorption naturally declines with age
- Include a daily source of dairy like milk, curd, or paneer if you eat it, rather than relying on occasional servings
- Consider a daily or weekly B12 supplement if you’re vegan or notice symptoms like fatigue, tingling, or brain fog, after checking with a doctor
- Look for fortified foods like breakfast cereals or plant-based milks when grocery shopping, and check labels for added B12
- Don’t rely on fermented foods or spirulina as a dependable B12 source, despite common claims — the research doesn’t support it
Vitamin B12 deficiency is quiet, slow-building, and incredibly common among Indian vegetarians, but it’s also one of the easiest nutritional gaps to close once you know it’s there. A simple annual blood test, a bit more attention to dairy and fortified foods, and a supplement if needed can make a real difference to your energy, mood, and long-term health.
