Vitamin B12 deficiency: 7 best vegetarian sources you should include in your diet
Vitamin B12 is mainly found in animal‑derived foods, so vegetarians need to be more intentional about getting it from dairy, eggs, and fortified or plant‑based sources. Below are 7 of the best vegetarian‑friendly options you can include in your daily diet.
1. Dairy products (milk, curd, paneer, cheese)
Plain cow or buffalo milk, curd (dahi), paneer, and cheese are natural B12‑rich foods. For example, one cup of low‑fat milk can provide around 50–60% of the daily requirement, and regular use of curd/paneer helps maintain B12 status.
2. Eggs
Eggs are one of the most reliable vegetarian sources; one large egg typically contains about 0.5 microgram of B12, which is roughly 20–25% of the daily need. Including 1–2 eggs a day (boiled, scrambled, or as omelette) can meaningfully contribute to B12 intake.
3. Fortified plant‑based milk
Many soy, almond, oat, or other plant milks are fortified with vitamin B12, often providing 0.5–1.2 mcg per serving. Choosing a consistently fortified brand and using it in tea, smoothies, or breakfast cereals helps maintain B12 levels.
4. Fortified breakfast cereals
Several breakfast cereals are enriched with B12; some can provide up to 2.4–6 mcg per 100 g, which is near or above the full daily requirement. A small bowl every day with milk or curd can efficiently cover much of your B12 need.
5. Nutritional yeast (fortified)
Fortified nutritional yeast is a popular vegan/vegetarian B12 booster; one tablespoon can provide about 2–2.4 mcg, depending on the brand. Sprinkle it on dals, curries, salads, or soups to add a cheesy, savory flavour plus B12.
6. Nori (seaweed)
Dried purple laver (nori) is one of the few plant‑based foods that contain bioactive vitamin B12 and is considered a suitable vegetarian source. Using nori sheets in snacks, wraps, or soups can supplement B12, though it should not be the sole source for long‑term use.
7. Fermented soy products (tempeh, fortified tofu)
Some tempeh and commercially fortified tofu products contain B12, especially if enriched; B12‑rich tempeh can give 1–2 mcg per 100 g depending on the brand and fermentation conditions. Combining these with curd or fortified milk gives a strong vegetarian B12 “stack” in meals.
If you are already diagnosed with B12 deficiency or follow a strict lacto‑ovo‑vegetarian or vegan pattern, your doctor may still recommend a B12 supplement or periodic injections alongside these foods. Regular monitoring of serum B12 and possibly methylmalonic acid (MMA) helps guide how much you need from diet versus supplements.
