Vitamin B12 Foods for Vegetarians: What Can You Actually Get From Food?
Vitamin B12 is an essential nutrient that helps your body make red blood cells, maintain normal nerve function and support DNA synthesis. For Indian vegetarians, getting enough B12 can be challenging because ordinary plant foods are not reliable natural sources of this vitamin.
Milk, curd, cheese and other dairy products can contribute vitamin B12 if you consume them. However, the amount you obtain depends on the product, portion size and frequency of consumption. People who avoid all animal-derived foods need a reliable source of fortified vitamin B12 or an appropriate supplement.
A study of 220 patients treated for vitamin B12 deficiency at a tertiary-care hospital in northern India found that approximately 86% were strict vegetarians. This finding highlights the importance of considering dietary patterns when assessing B12 deficiency. It does not mean that 86% of all Indian vegetarians are deficient.
Eggs also contain vitamin B12 and are discussed separately for readers who choose to eat them. You do not need to include eggs in your diet to follow the recommendations in this article.
Which Vegetarian Foods Have Vitamin B12?
For lacto-vegetarians who consume dairy, milk, curd and certain other dairy products can contribute vitamin B12. Fortified foods provide another option, including for people who avoid dairy.
Ordinary dal, roti, rice, vegetables, fruits, nuts and seeds are not dependable sources of naturally occurring vitamin B12, regardless of how varied your diet is.
Vitamin B12 Content of Selected Foods
The following table uses approximate reference values from the US National Institutes of Health (NIH) where specified. These are not universal values for Indian products. Vitamin B12 concentrations can differ with food composition, processing, preparation and brand.
| Food | Approximate vitamin B12 | Practical note |
|---|---|---|
| Milk | About 1.3 µg per 240 ml in the NIH reference | A useful everyday source; Indian milk values may differ |
| Cheddar cheese | About 0.5 µg per 42 g in the NIH reference | Contributes B12, although the amount depends on the cheese |
| Egg; large | About 0.5 µg per egg in the NIH reference | An optional source for people who eat eggs |
| Curd (dahi) | Depends on composition and preparation | Can contribute B12; use a suitable food-specific value if available |
| Paneer | Depends on composition and preparation | May contribute B12, but do not assume a precise value without supporting data |
| Fortified breakfast cereal | Depends on the product | Check the nutrition label for added vitamin B12 |
| Fortified nutritional yeast | Depends on the product | Some products contain substantial amounts of added B12; check the label |
Data note: IFCT 2017 does not provide vitamin B12 values in its main food-composition tables. The milk, cheese and egg figures above are NIH reference values, not a substitute for Indian-specific measurements. Product-specific fortified-food values should be taken from the relevant label.
Chaas, mor and majjige are diluted curd preparations. Their vitamin B12 content per glass depends on the amount and type of curd used, as well as the final dilution. Therefore, they should not automatically be assigned the same value as thick curd.
How Much Vitamin B12 Can a Vegetarian Get From Food?
The following examples show how common Indian foods may contribute to daily vitamin B12 intake. Estimates use the food values discussed above and an adult reference intake of 2.2 µg/day (ICMR-NIN, 2020).
| Dietary pattern | Foods consumed in a day | Approx. vitamin B12 | Remark / Description |
|---|---|---|---|
| Dairy-inclusive vegetarian | 2 glasses milk (500 ml) + 1 bowl curd (200 g) | Around 4.56 µg | May provide more than the daily reference intake based on these estimates. |
| Limited dairy | 1 glass milk (250 ml) + 1 bowl curd (200 g) | Around 2.71 µg | May meet the daily reference intake, depending on actual food values. |
| Paneer-focused meal pattern | 100 g paneer + 1 glass milk (250 ml) | Around 2.24 µg | Approximately equal to the daily reference intake. |
| Egg-inclusive diet | 1 glass milk (250 ml) + 2 large eggs | Around 2.85 µg | Can provide a substantial contribution to daily B12 intake. |
| Vegan diet without fortified foods | Dal, rice, vegetables, fruits, nuts and seeds | No dependable B12 estimate | These foods are not reliable sources of vitamin B12 unless appropriately fortified. |
Note: These are illustrative estimates, not guaranteed values for all Indian food products. Actual vitamin B12 content varies with the product, processing and preparation. The figures represent estimated B12 content in food, not the amount absorbed by the body.
What Do These Examples Tell Us?
Dairy can make a substantial contribution: Milk and curd together may supply a considerable amount of vitamin B12.
Paneer alone is not a concentrated source: Even a 100 g serving contributes relatively little compared with the amount needed each day.
Eggs can contribute, but quantity matters: Their contribution depends on how many eggs are eaten and what other B12 sources are included in the diet.
A vegan diet needs a dependable B12 source: Choose appropriately fortified foods or discuss supplementation with a qualified healthcare professional.
Does Milk Help Improve Vitamin B12 Status?
Milk can be a useful source of vitamin B12 for people who consume dairy. An intervention study conducted in Pune reported improved B12 status following regular milk consumption among young vegetarians with low B12 status.
This provides evidence that milk can contribute to improving B12 status in the studied population. However, the result should not be interpreted as proof that milk alone will correct every deficiency. The appropriate approach depends on the person's B12 status, dietary intake, absorption and clinical circumstances.
Are Eggs a Source of Vitamin B12 for Vegetarians?
Yes. Eggs contain vitamin B12, with much of it found in the yolk. The NIH reference value for one large egg is approximately 0.5 µg of B12. A large egg also provides roughly 6 g of protein and around 70 calories, although the exact values vary with egg size and preparation.
Eggs are optional, not essential. In India, whether eggs fit within a person's vegetarian diet can depend on individual, family and cultural preferences. This article does not ask readers to change those preferences.
People who eat eggs can obtain some B12 from them. Lacto-vegetarians can instead obtain B12 from dairy products and/or fortified foods. People who avoid all animal-derived foods need to plan a reliable source of fortified B12 or use an appropriate supplement.
Absorption varies with the food, the amount consumed and individual circumstances. Although research suggests that B12 from eggs may be less bioavailable than B12 from some other sources, a single universal absorption percentage should not be applied to every person. For this reason, this article does not calculate an exact amount of “usable” B12 from an egg.
Do Paneer and Cheese Count as Vitamin B12 Sources?
Milk and curd can contribute meaningful amounts of vitamin B12 to a vegetarian diet, although the actual amount depends on the product and serving size. Cheese also contains vitamin B12, but its concentration varies by type. Paneer should be assessed using suitable Indian-specific food-composition data rather than assuming that values reported for other cheeses apply directly to it.
For everyday meal planning, include milk or curd if they fit your diet, and treat paneer and cheese as foods that may contribute to your vitamin B12 intake rather than guaranteed sources of a specific amount. When product-specific nutrient information is available, use it to estimate your intake more accurately. If you consume little or no dairy, consider reliably fortified foods or an appropriate supplement instead of depending on uncertain food values to meet your vitamin B12 needs.
Can You Get Vitamin B12 from Plant-Based Foods?
Ordinary plant foods such as dal, cereals, vegetables, fruits, nuts, seeds and sprouts are not reliable natural sources of vitamin B12. Although some plant-based and fermented foods are promoted online as B12 sources, their vitamin B12 content and biological activity can vary. Finding B12-like compounds in a food does not necessarily mean that it provides enough biologically active vitamin B12 to meet daily requirements.
What about commonly discussed foods?
- Spirulina and some seaweeds: May contain B12-like compounds that are not necessarily biologically active. They should not be relied on to meet vitamin B12 requirements.
- Mushrooms: Some varieties may contain small or variable amounts, but they are not dependable sources for meeting daily needs.
- Tempeh and other fermented foods: Fermentation does not automatically produce a reliable amount of active vitamin B12.
- Idli and dosa: Fermented batter should not be considered a dependable source of vitamin B12.
- Sprouts and vegetables: These are nutritious foods, but they should not be relied on for vitamin B12. Deliberately consuming soil or unwashed produce is not a safe way to obtain it.
- Fortified foods: These are different because vitamin B12 is added during production. Check the nutrition label to confirm the amount per serving.
For practical purposes, people who consume dairy can include milk, curd and other suitable dairy products in their diet. Those following a vegan diet should choose reliably fortified foods or an appropriate B12 supplement. People with a diagnosed deficiency may require medical treatment, depending on its severity and cause.
Should Vegetarians Take a Vitamin B12 Supplement?
Vegans generally need a reliable source of vitamin B12 from fortified foods or supplements, as ordinary plant foods are not dependable sources. For lacto-vegetarians and lacto-ovo vegetarians, the need for supplementation depends on their dairy and egg intake, B12 status and ability to absorb the vitamin. Consult a healthcare professional if you are unsure whether your diet provides enough.
Milk and curd can be affordable B12 sources, but their content varies. If your intake is inconsistent, a supplement may provide a more predictable amount and can be cost-effective. Older adults and people taking medicines such as metformin or certain acid-reducing drugs may have a higher risk of deficiency.
Considering a supplement? Compare the dosage and cost per serving, and seek medical advice if you have a diagnosed deficiency. Explore a vitamin B12 supplement.
