Vitamin B12 (cobalamin) is a vital nutrient that your body can’t make on its own, so you need to get it in your diet. Vitamin B 12 is crucial for a range of body functions, from the regulation of cell metabolism to the production of red blood cells.

What is Vitamin B12?

Vitamin B12 is a water-soluble vitamin that has many functions in your body. Ensuring that a person has enough vitamin B-12 in his or her diet is essential for optimal health. The vitamin's health benefits include:

  • the formation and division of red blood cells
  • protecting the nervous system
  • synthesizing a person’s DNA
  • providing the body with energy

If you are eating a lot of meat and dairy, getting enough vitamin B-12 in your diet is easy. But you may struggle to meet the recommended daily value (DV) if you are:

  • an older adult
  • vegan or vegetarian
  • having pernicious anemia
  • having a digestive disorder which makes it hard for your body to absorb nutrients
  • pregnant

The recommended B-12 daily allowance (RDA) is dependent on the age of a person:

  • Adults and teenagers: 2.4 micrograms (mcg) per day;
  • Children aged 9 to 13: 1.8 mcg per day
  • Children aged between 4 and 8: 1.2 mcg per day
  • Toddlers aged 1 to 3: 0.9 mcg per day
  • Children aged 7 to 12 months require 0.5 mcg of B-12 per day and babies less than 6 months old need only 0.4 mcg/day.
  • Pregnant women need 2.6 mcg while breastfeeding women requires 2.8 mcg/day.

With the help of a protein called intrinsic factor, vitamin B12 is absorbed into the stomach. This substance binds to the molecule of vitamin B12 and eases its absorption into your blood and cells.

The excess vitamin B12 is stored in the liver by your body, so if you consume more than the RDI, your body will save it for future use.

You may develop a deficiency of vitamin B12 if your body doesn't produce enough intrinsic factor, or if you don't eat enough food rich in vitamin B12.

Vitamin B12 is found primarily in animal products, in particular meat and dairy products. Fortunately for those dieting on vegans, fortified foods can also be good sources of this vitamin.

Vitamin B12 Food List

1. Milk and dairy products

Milk and Milk Products

Milk and dairy products such as yogurt and cheese are great protein sources, and several vitamins and minerals, including vitamin B12.

One cup (240 ml) of whole milk supplies vitamin B12 with 46 percent of DV.

Cheese also represents a rich source of vitamin B12. One large slice of Swiss cheese (22 grams) may contain about 28 percent of the DV.

Full-fat plain yogurt may be a decent source, too. It has even been shown to help improve the status of vitamin B12 in people who have a vitamin deficiency.

Interestingly, studies have shown that in milk and dairy products the body absorbs the vitamin B12 better than vitamin B12 in beef, fish or eggs).

A study of more than 5,000 people, for example, showed that dairy was more effective then fish in increasing vitamin B12 levels.

2. Fortified non-dairy Milk

Nondairy milk is popular among those who would like a nutritious vegan substitute for dairy milk.

While soy, almond and rice milk are not naturally rich in vitamin B12, they are usually fortified, making them an excellent source of this vitamin.

One example is soy milk, which can provide up to 86 percent of the DV in 1 cup (240 ml) for vitamin B12.

For this reason, fortified non-dairy milk may be a great option for those wishing to increase their intake of vitamin B12 and avoid deficiencies.

As with vitamin B12 in other fortified sources, vitamin B12 is synthetically produced in the nondairy milk, so it is vegan-friendly.

3. Eggs

Eggs

Eggs are a great source of whole protein and B vitamins, particularly B2 and B12.

Two large eggs (100 grams) supply vitamin B12 with about 46 percent of the DV plus 39 percent of the DV for vitamin B2.

Research has shown that egg yolks have higher levels of vitamin B12 than egg whites and that it is easier to absorb the vitamin B12 in egg yolks. So, it is recommended that you eat whole eggs instead of just eating their white parts.

Besides getting a good dose of vitamin B12, you'll be getting a healthy amount of vitamin D. Eggs are one of the few foods that contain them naturally, with 11 percent of the DV in two large eggs.

4. Nutritional Yeast

Nutritional yeast is a good source of protein, vitamins and minerals for vegan use.

It is an especially grown yeast species for use as food, not as a leavening agent in bread and beer.

Nutritional yeast does not naturally contain vitamin B12. It is commonly fortified though, making it a great source of vitamin B12.

As with fortified cereals, vitamin B12 is vegan-friendly in nutritional yeast.

As with fortified cereals, the nutritional yeast is vegan-friendly as it's made synthetically.

Two tablespoons of nutritional yeast (15 grams) may contain up to 733 percent DV for vitamin B12.

Fortified Cereals

Nowadays a lot of bran and whole wheat oat cereals come with vitamin B12 fortified.

These fortified cereals can help you get your vitamin B12 daily. Combine these with the milk to increase your meal 's nutritional quotient.

Although not commonly recommended as part of a healthy diet, fortified cereals, especially B12, can be a good source of B vitamins. Fortification of food is the process of adding nutrients that aren't in the food originally.

If you choose to use fortified cereal to increase your intake of vitamin B12, select a brand low in added sugar and high in fiber or whole grain.

3 ounces of chicken (85 grams) contains 0.3 mcg of Vitamin B12.

8. Clams

Clams are small, chewy, nutrient-packed shellfish

This mollusk is a lean protein source and contains very high vitamin B12 concentrations. In just 20 small clams, you can get more than 7,000 percent of the DV.

Clams, especially whole baby clams, also provide largely amounts of iron, with nearly 200 percent of the DV in a serving of 100-gram (3.5-ounce).

It has also proved that clams are a good source of antioxidants.

Interestingly, the boiled clam broth is also high in vitamin B12.

Rainbow trout is considered one of the healthiest fishes.

This species of freshwater fish is a big source of protein, healthy fats, and vitamin B.

Why Vitamin B-12 is important?

If you don't take enough vitamin B12 foods in your diet, your body will begin to show signs of its deficiency. While any nutritional deficiency is considered to be bad for overall health, a Vitamin B12 deficiency would eventually show the symptoms described below.

  • Muscle Weakness
  • Digestive Issues like constipation
  • Lack of Concentration and Poor Memory
  • Shortness of Breath
  • Anemia
  • Fatigue
  • Loss of appetite
  • Weight loss
  • Numbness and tingling
  • Balance problems

Vitamin B12 deficiency

When you have a vitamin B-12 deficiency, your body will not be able to produce healthy red blood cells. The unhealthy cells die off before they get enough new ones to produce. This cycle, left unchecked, results in a condition called megaloblastic anemia, also called pernicious anemia. Megaloblastic anemia may occur if you are not eating enough foods that contain vitamin B-12 or your body is unable to absorb the vitamin.

Symptoms of anemia are often severe and may include:

  • paleness
  • extreme fatigue
  • irritability
  • decreased appetite
  • diarrhea
  • weakness
