Many people are surprised to learn that fruits and vegetables do not naturally contain Vitamin B12, unlike folic acid, which is found in many plant foods. B12 is essential for nerve function, DNA production, and red blood cell formation, but it is primarily found in animal products, unlike most other B vitamins, which are abundant in plant foods.
For vegetarians and vegans, this presents a challenge, which increases the risk of deficiency, especially for people taking certain medications. You must get enough B12 through fortified foods and supplements to prevent vitamin B12 deficiency.
In this blog, we’ll discuss the best vitamin B12 sources and share meal ideas that include many foods along with folic acid to help prevent neural tube defects and meet your daily B12 needs.
Vitamin B12 is one of the most crucial nutrients for human health, which plays a significant role in the formation of healthy red blood cells, DNA synthesis, recovery from autoimmune disease, and neurological function. Although it is an essential nutrient, B12 is not found naturally in fruits or vegetables, which makes it a challenge for vegetarians and vegans.
Unlike many other vitamins and minerals that are widely available in plant foods, B12 is exclusively found in animal-based foods. The sources of Vitamin B12 include meat, red meat, dairy, eggs, and fish.
The chemical name of vitamin B12 is cobalamin, which contains cobalt—hence the name. Cobalamin, a water-soluble vitamin, is a very significant compound for the body that enables several functions of the human body.
B vitamins are very significant for maintaining gut health, mental health, and keeping the nervous system healthy. Vitamin B12 provides several important health benefits. It can reduce the risk of heart disease. Some research has explored links between B12 status and cancer risk, but evidence is not strong enough to conclude that B12 prevents or treats breast cancer. Vitamin B12 is essential in some of the most important processes in the body:
Red blood cell formation: B12 is essential for proper red blood cell development. Deficiency can lead to megaloblastic anaemia, where red blood cells are enlarged and malformed, reducing oxygen transport and causing fatigue.
Nervous system health: B12 is essential for the formation and proper functioning of brain and nerve cells, including the production of the myelin sheath, which protects nerve fibers. Deficiency may cause neurological issues such as numbness, tingling, balance problems, and cognitive difficulties that can be irreversible if untreated. Intrinsic factor, a protein produced in the stomach, is required for B12 absorption.
DNA Synthesis and Regulation: Vitamin B12 is a necessary cofactor in the enzymes used in the production and control of DNA, the genetic makeup in every cell.
Metabolism: It aids the transformation of food into energy through the aid in protein and fat metabolism.
Pregnancy and Development: It is essential in pregnancy to avoid severe birth defects, including neural tube defects, and ensure sufficient infant growth.
All of the above symptoms—fatigue, pale skin, numbness, hair loss, and low concentration—could be consequences of a vitamin B12 deficiency. Symptoms may also emerge gradually with time and, therefore, be easily missed or confused with other illnesses.
B12 deficiency manifests itself primarily through the symptoms of its involvement in the formation of red blood cells and nervous system functioning.
Fatigue and Weakness: This is considered one of the first and most frequent symptoms due to the inability of the body to produce sufficient healthy red blood cells to efficiently transport oxygen (anaemia).
Pale or Yellow Skin: Anaemia may cause a pale color of the skin, whereas the rapid disintegration of the big, faulty red blood cells may produce a yellowish hue (jaundice).
Shortness of Breath and Dizziness: The decreased carrying capacity of oxygen in the blood may cause one to experience a sensation of breathlessness and lightheadedness, particularly during exertion.
Sore or Swollen Tongue: A smooth, painful, and red tongue (glossitis) or mouth ulcers may be caused by the action on fast-replicating cells.
Rapid Heart Rate: The heart can beat at a rapid rate to overcome the decreased oxygen supply in the entire body.
Hair changes: Although more research is needed, B12 deficiency is linked to hair loss, thinning, and premature greying, possibly due to reduced blood supply to hair follicles and impaired cell production.
Digestive Problems: Nausea, vomiting, diarrhoea, constipation, loss of appetite and weight loss can be experienced.
Numbness and Tingling: A frequent complaint of the deficiency is referred to as a pins and needles feeling in the hands, legs or feet (paresthesia), which is a typical manifestation of nerve damage.
Difficulty Concentrating/Brain Fog: Low levels of B12 may affect cognitive ability, causing memory issues, confusion, and inability to concentrate.
Difficulty Walking and Balance Problems: The nerves may deteriorate to cause difficulty in walking, as well as balance.
Mood Changes: B12 deficiency is associated with depression, irritability, and anxiety.
Vision Problems: In serious and uncommon instances, the optic nerve may be damaged, leading to blurred or distorted vision, but this can be reversible in case it is noticed early.
Vitamin B12 or, cobalamin is essential to the nerve cells, the creation of red blood cells, and the synthesis of DNA. As your body is not in a position to make it, you need to get it through your diet or otherwise. The best method of naturally raising B12 is through food that is mainly of animal origin.
These natural sources are especially important because B12 absorption often decreases with age or digestive disorders. Vitamin B12 can be increased by eating foods rich in this vitamin through diet.
Meat and Poultry: Beef, lamb, and chicken are good sources. B12 is extremely high in organ meats, particularly beef liver.
Seafood: Shellfish and fish are a great choice. Clams, salmon, trout and tuna are very good sources.
Eggs: The eggs are a good source of B12 and other important nutrients.
There are virtually no natural plant sources of B12, which creates a challenge for people following vegetarian or vegan diets. If you maintain a vegan diet, there are also several food sources that will be good for your overall health.
Dairy Products: B12 is a natural source in milk, cheese and yoghurt, and thus it is essential for dairy-consuming vegetarians.
Fortified products: B12 is added to many foods during processing, making them a key source for vegans and vegetarians.
Examples would be breakfast cereals, plant-based milks (soy, almond, rice), nutritional yeast, and certain meat substitutes. These fortified products help meet B12 requirements, especially for people with limited absorption.
Supplements (Where Necessary): Dietary supplements are a good option where dietary intake is inadequate or absorption may be a problem. Such supplements provide several health benefits. If you can't get the natural food sources of vitamin B12, the dietary supplements help maintain adequate B12 levels when dietary intake is insufficient.

Essential for vegans/vegetarians; check product labels for B12 content. |
Supplements/Medication |
Pills, sublingual tablets, injections, nasal gels |
Used when dietary intake is insufficient or absorption is impaired; consult a doctor for proper dosing. |
Even with a B12-rich diet, several factors may hinder absorption:
Age: As people age, stomach acid levels often decrease, making it harder to release B12 from food for absorption.
Gastrointestinal Issues: Conditions like Crohn's disease, celiac disease, or prior weight-loss surgeries affect the small intestine's ability to absorb nutrients.
Medications: Certain medications, such as acid reflux drugs or metformin, can interfere with absorption over long-term use.
If you have concerns about your B12 levels or potential absorption issues, consult a healthcare provider to determine the best course of action, which may include monitoring levels or suggesting supplements.
Vitamin B12 is predominantly found in animal products. The daily recommended intake for most adults is 2.4 micrograms—a relatively small amount that can be met easily through a balanced diet. A quick look at foods high in Vitamin B12 for all diet types. For those following vegetarian or vegan diets, fortified foods provide a reliable alternative source. Natural plant-based foods, such as the most common vegetables and fruits, generally contain negligible to trace amounts of B12.

Animal products contain the absolute best natural sources of vitamin B12 because they are the sources of the nutrient in the most bioavailable form.
Clams: One of the richest sources, 3 ounces (85g) of cooked clams can supply you with a considerable portion of what you need in a day.
Beef Liver: Organ meat is unbelievably rich in nutrients. Beef liver is a powerhouse of B12, iron and other vitamins. It is one of the best animal-based sources of Vitamin B12.
Fish: Salmon and trout are good sources of fatty fish. The daily needs of an adult can be conveniently supplied by a conventional serving.
Beef: Beef, especially lean beef, is a very good source of red meat.
Dairy: Milk and yoghurt also contain Vitamin B12.
Eggs: A hard-boiled egg is a typical staple which supplies a firm, consistent amount of B12.
Fortified foods are important to people who restrict or renounce animal foods in order to avoid deficiency. The quantity of B12 in these items may vary widely, as per product and serving size; thus, the most recent nutritional details can be found on the label of the product.
Nutritional Yeast: Often a favorite supplement among vegans, nutritional yeast is fortified and has the taste of cheese and may be sprinkled on most dishes to increase the intake of B12.
Fortified Plant-Based Milks: Soy, almond and oat milk are increasingly being fortified to resemble the B12 content present in dairy milk.
Fortified Breakfast Cereals: B12 is added to many of the common cereals. One should always examine the nutrition facts box to determine whether the cereal he or she is buying is fortified or not.
Among those who are on an Indian vegetarian diet (ovo-lacto-vegetarian), one may be able to get enough Vitamin B12 by eating dairy products and fortified foods. Vegans need to rely on fortified foods or supplements because natural plant sources of B12 are negligible.
The major vegetarian-friendly sources of Indians are:
Curd (Dahi): It is a common ingredient in most Indian dishes, which contains B12 and probiotics. If you consume a vegan diet, you can consume almond milk or soy milk as well. That will also provide you with the vital nutrients.
Paneer (Cottage Cheese): A multifunctional source of protein and B12.
Cow Milk: The most readily available and the most common source of B12 in the Indian diet.
Fortified Breakfast Cereals: Many commercial breakfast cereals are fortified with B12, providing an easy way to start the day. This is a simple method of beginning the day with a B12 shot. If you consume a vegan diet, you won't face any issues, as many breakfast cereals are available now in the market.
Nutritional Yeast: A strong fortified alternative to those who abstain from all animal products (vegans).
These foods can be incorporated into everyday Indian cuisine to maintain sufficient B12 levels, such as:
Breakfast: A bowl of fortified breakfast cereal or oats in cow's milk (or fortified plant milk) is also a major kick. Parathas or vegetable dishes pair well with curd.
Lunch/Dinner: It is best to have something made with paneer (Palak Paneer, Paneer Bhurji or Matar Paneer) as such meals are culturally appropriate and very rich in protein and B12.
Snacks/Sides: A drink of chaas (buttermilk) or Lassi, which is prepared out of curd, is a refreshing and B-12-based side beverage that can be consumed with any meal. Fortified nutritional yeast can be added to poha or any other savoury snacks without much change in the flavour profile.
Vitamin B12 is also significantly lacking in almost all plant foods, including popular fruits and vegetables. There is no biological need for B12 by plants, and it is therefore not produced or stored in large quantities.
The answer to this is no, in most instances. The natural quantities of B12 in most fruits and vegetables are very low to insignificant.
Foods often reported to contain B12, such as certain mushrooms, usually only have trace amounts, often due to soil bacteria or farming practices, rather than naturally occurring B12.
Nevertheless, vegetables and fruits are important for general nutrition. They also contain plenty of other B vitamins (such as folate and B6) and antioxidants, which will aid metabolism and may enhance the overall absorption and use of the other B12-rich foods that you eat.
Although fruits and vegetables cannot meet daily B12 needs naturally, some foods may contain B12 when fortified.
Vegetables with Vitamin B12
Under certain circumstances, some vegetables can provide some traces:
Mushrooms: It is the most widespread exception. Some types of mushrooms (such as fresh shiitake and certain types of oyster mushrooms) have been found in research to have trace levels of B12, presumably picked up by the mushrooms as they grow on the material they are cultured on. Nevertheless, these figures are not stable and are not high enough to be taken as a main source.
Spinach, Beetroot and Potato: These are vegetables that do not occur naturally with B12. There is some research on fortifying the soil with B12 to examine whether plants take it up (“biofortification), which is not a common business practice, and it should not be assumed that commercial produce is rich in B12.
Vitamin B12 is a key nutrient which is vital to the general health of the body, specifically facilitating metabolism and brain wellness, and red blood cell development. The body cannot synthesize B12; therefore, it must be obtained through diet.
In the case of vegetarians and vegans, they can keep their B12 levels healthy with the regular intake of fortified food (cereals, plant-based milks and nutritional yeast) and with the help of the relevant supplements.
Since the symptoms of deficiency may be mild and build gradually, some of these aspects as age and diet, influence absorption. Consult a healthcare provider for appropriate testing if you are at risk of deficiency.
The only natural vegetarian sources of B12 are dairy products and eggs. All plant-based sources must be fortified to provide adequate B12. Breakfast cereals, plant-based milk, and nutritional yeast are also fortified with B12. Incorporating them frequently may help vegetarians achieve their daily needs without using meat or fish.
Vitamin B12 can not be found naturally in most fruits and vegetables. Fermented foods may contain the smallest traces, such as tempeh or some algae (e.g., nori). Nonetheless, fruits and vegetables alone cannot provide sufficient B12 in the body, and, therefore, vegetarians and vegans will typically have to supplement or eat fortified foods.
Foods fortified with Vitamin B12, dairy, and eggs are also included in the diet to raise Vitamin B12 levels. In the case of vegans, B12 supplements or fortified plant-based milk work. Under extreme deficiency, physicians can prescribe B12 injections. Constant check of B12 blood levels provides effective and safe correction of deficiency.
Fatigue, weakness, pale skin, and shortness of breath are some of the effects of vitamin B12 deficiency. Neurological symptoms are tingling of hands or feet, difficulty in balance, memory problems and change of mood. In extreme situations, anaemia and cognitive impairment can take place. Primary damage is avoided by early diagnosis and replacement.
Yes, the Vitamin B12 deficiency in India is very widespread, especially in vegetarians, as the majority of the sources of B12 are animal-based. Research indicates that the deficiency has been seen among 4060 per cent of the population and in many cases results in anaemia, fatigue and neurological problems. The prevention of deficiency can be achieved by means of awareness, dietary adaptation, and supplementation.
Yes, fortified cereals and fortified milk are good sources of Vitamin B12 for vegetarians. They assist in fulfilling the daily needs without meat consumption. Combining these with dairy, eggs, or supplements ensures adequate B12 intake, especially for high-risk groups such as vegans and the elderly.
Milk, curd, paneer, ghee, and eggs are all Indian foods that are high in Vitamin B12. There are also fortified foods, including breakfast cereals and soy milk. Daily meals with the supplementation, when necessary, allow vegetarians to stay up to the proper level of B12 without resorting to non-vegetarian food.
Plant-based milk, fortified cereals, and supplements are vegan sources of Vitamin B12. There are some algae, such as nori or chlorella, that can contain B12, though the content can differ. Taking fortified food or supplements is necessary to avoid deficiency because natural foods of vegetarians have low or no dependable amounts of B12.
