Vitamin B12 is an essential nutrient that helps the body make red blood cells and DNA. It is mainly found in animal products, especially meat, fish, and dairy products. For those who don't consume animal products, B12 can be sourced from fortified foods like cereals, nutritional yeast, and plant milk, or from supplements. The average daily intake of vitamin B12 is about 7.2 micrograms for meat-eaters, but only 0.4 micrograms for vegans. A vitamin B12 deficiency can cause severe complications and ill health, so it is important to ensure adequate intake through diet or supplements.

What You'll Learn
Eat more meat, fish, and seafood
Meat, fish, and seafood are excellent sources of vitamin B12. This is especially true for organ meats, such as liver and kidneys, which are very high in vitamin B12. For instance, a 3.5-ounce (100-gram) serving of lamb liver provides an incredible 3,571% of the Daily Value (DV) for vitamin B12. Lamb kidneys provide about 3,000% of the DV per 3.5-ounce (100-gram) serving.
Fish and seafood are also excellent sources of vitamin B12. Clams, a type of shellfish, are particularly rich in this vitamin, with a 3-ounce (85-gram) serving providing 3504% of the DV. Other good seafood options include conch, a sea snail that provides 278% of the DV per 127-gram cup, and whelk, another sea snail that offers 642% of the DV per 3-ounce (85-gram) serving.
When it comes to fish, salmon is a great choice for vitamin B12. A 178-gram half fillet of farmed Atlantic salmon provides over 200% of the DV. Rainbow trout is another nutritious option, with a 3.5-ounce (100-gram) serving offering about 312% of the DV.
Meat is also a good source of vitamin B12. For example, beef is an excellent option, with a grilled flat iron steak (about 190 grams) providing 467% of the DV. Pork kidney is another choice, delivering 276% of the DV per three-ounce (85-gram) serving.
Incorporating a variety of these foods into your diet can help ensure that you acquire an adequate amount of vitamin B12, which is crucial for human health.

Consume dairy and eggs
Dairy and eggs are good sources of vitamin B12. Dairy products, especially milk, are a good way to increase your B12 intake. Cows pass B12 into their milk, and the concentration of B12 in bovine milk is stable with regard to breed, feed, season, and stage of lactation. A cup of milk contains 1mcg of B12, which is about 40% of the daily value (DV) for B12 per serving. Yogurt is another dairy product that contains vitamin B12, with 3/4 of a cup providing 1mcg of B12.
Eggs are another way to increase your vitamin B12 intake. One hard-boiled egg contains about 0.6mcg of vitamin B12, which is about 25% of the recommended daily intake. If you are vegetarian or vegan, eggs and dairy can be a good way to ensure you are getting enough vitamin B12. However, if you are vegan, you may need to take a daily or weekly B12 supplement in addition to consuming eggs and dairy, as it can be difficult to get enough B12 from dietary sources alone.
In addition to dairy and eggs, there are other dietary sources of vitamin B12 that you may want to include in your diet. Meat, especially organ meats like liver and kidneys, are very high in vitamin B12. For example, a 3.5-ounce serving of lamb liver provides 3,571% of the DV for vitamin B12. Seafood, especially clams, is also a good source of B12. Three ounces of lean beef provide 2.8mcg of B12, while one egg provides 0.6mcg.
Fortified foods, such as breakfast cereals and non-dairy milks, can also be a source of vitamin B12. However, if you rely on these foods for your B12 intake, be sure to check the nutrition label to ensure you are buying a product that is fortified. Nutritional yeast, a special type of yeast with a nutty, cheesy flavour, is another source of B12 that can be sprinkled over foods.

Take vitamin B12 supplements
Vitamin B12 is an essential nutrient, and a deficiency can lead to severe complications and ill health. If you are deficient in vitamin B12, your doctor may recommend vitamin B12 injections. However, you can also take a supplement to increase your vitamin B12 levels.
Vitamin B12 supplements are available in the form of tablets or liquids that can be taken by mouth or placed under the tongue (sublingually). They can also be injected, and research has shown that vitamin B12 taken by mouth and muscular injection are equally effective at restoring B12 levels in people with a deficiency.
If you are vegan or vegetarian, you may need to take a vitamin B12 supplement, as vitamin B12 is mainly found in animal products, especially meat and dairy products. Older adults, people with gastrointestinal conditions, and those on certain medications may also need to take a supplement.
If you are pregnant or breastfeeding, it is especially important to ensure adequate vitamin B12 intake, as your body may require additional vitamin B12. You can speak to your doctor or pharmacist about choosing the right supplement and dosage for you.
It is important to note that vitamin B12 deficiency can be caused by various factors, including a lack of vitamin B12 in the diet, certain medications, and digestive system disorders. If you are concerned about your vitamin B12 levels, it is best to consult your healthcare provider.

Try fortified foods
Fortified foods are a great way to add vitamin B12 to your diet, especially if you follow a vegan or vegetarian diet. Fortified foods are those that have certain vitamins and nutrients added to them that they don't naturally contain.
Vitamin B12 is only naturally found in animal products, such as meat, fish, and dairy. Therefore, people who follow a vegan or vegetarian diet are at a higher risk of vitamin B12 deficiency and should consider including fortified foods in their diet.
Some common fortified foods that contain vitamin B12 include:
- Breakfast cereals: Look for vegan-friendly, fortified cereals to ensure you are getting a good amount of vitamin B12.
- Nutritional yeast: Nutritional yeast is a plant-based product that is often fortified with vitamin B12. It is a great option for vegans and vegetarians, as it is a complete protein and a good source of other B vitamins.
- Plant milk: Some plant-based milk alternatives are fortified with vitamin B12. Check the nutritional label to ensure that vitamin B12 has been added.
- Bread: Certain types of bread are fortified with vitamins and minerals, including vitamin B12. Again, be sure to check the nutritional information to confirm the presence of vitamin B12.
It is important to note that while fortified foods can be a good source of vitamin B12, the amount of the vitamin they provide may vary. Always read the nutritional information on the product label to ensure that vitamin B12 has been added and to know how much you are consuming.
In addition to fortified foods, some other plant-based sources of vitamin B12 include seaweed and fermented foods. However, these sources may not provide sufficient amounts of the vitamin, so it is important to include a variety of fortified foods in your diet or consider taking a supplement, especially if you are at risk of vitamin B12 deficiency.

Monitor health and intake
Monitoring your health and intake is crucial when it comes to vitamin B12. Vitamin B12 is an essential nutrient, and a deficiency can lead to severe health complications. To prevent this, it is important to be aware of your B12 levels and make adjustments to your diet or consider supplements if necessary.
Firstly, it is important to understand the factors that can contribute to a vitamin B12 deficiency. Vitamin B12 is mainly found in animal products, especially meat, dairy, and eggs. Therefore, those following a vegan or vegetarian diet are at a higher risk of deficiency. In addition, older adults, individuals with gastrointestinal issues, and people on certain medications may also be more prone to B12 deficiency. If you fall into any of these categories, it is important to pay close attention to your B12 intake.
If you suspect you may have a vitamin B12 deficiency, consult your doctor. They can perform a simple blood test to check your B12 levels. If a deficiency is detected, your doctor can advise you on how to increase your B12 levels, which may include dietary changes or supplements. For those with severe deficiencies, B12 injections may be recommended.
To monitor your health and intake, keep track of the foods you consume that are rich in vitamin B12. Animal products such as lamb liver, kidneys, clams, and trout are excellent sources of B12. If you follow a plant-based diet, look for fortified foods such as cereals, nutritional yeast, and plant milk that have been enhanced with B12. Keep in mind that not all fortified foods are created equal, so always check the nutritional information to ensure the product contains vitamin B12.
Additionally, be mindful of factors that can interfere with vitamin B12 absorption. For example, frequent alcohol consumption can damage your digestive system and hinder B12 absorption. Certain medications can also impact B12 levels, including metformin, proton pump inhibitors, histamine H2 blockers, and oral contraceptives. If you take any of these medications, consult your healthcare provider to discuss ways to manage your B12 intake effectively.
