Fortified Food With B12


You probably already know that fortified foods with B12 are going to be an important part of keeping your body running smoothly.

Unfortunately, it can be hard to find high-quality sources of B12 that taste good and nourish your body. That’s why we’ve created this list of the best fortified foods with B12—all of which are guaranteed to put the spring back in your step and the shine back in your hair!

Fortified Food With B12

Animal products, such as meat, fish, and eggs, contain vitamin B12 in varying amounts. The following is a list of good sources:

  • clams
  • liver
  • trout
  • salmon
  • canned tuna
  • beef
  • low fat yogurt
  • low fat milk
  • ham
  • eggs
  • chicken breast

A person should consume these foods in moderation as part of a healthful diet. Learn how to eat a healthful diet here.

The above food sources are all unsuitable for people following an entirely plant-based diet.

Vegan sources

Vitamin B12 is not present in plant foods, so people on a plant-based diet need to obtain it through fortified foods and supplements.

Foods that are sometimes fortified and may contain vitamin B12 in varying amounts include:

  • plant milk, such as soy, almond, oat, cashew, and coconut milk
  • breakfast cereals
  • margarine and spreads
  • nutritional yeast
  • tofu
  • fruit juice
  • dairy-free yogurt

It is important to read the nutritional information on a fortified product to ensure that it contains vitamin B12.

Foods or drinks to avoid 

Some foods and drinks can interfere with vitamin B12 intake:

Folic acid-fortified foods

Folate (vitamin B9) is an essential nutrient, especially before and during pregnancy. The Centers for Disease Control and Prevention (CDC) state that women of reproductive age need 400 micrograms (mcg) of folic acid (synthetic folate) each day.

However, too much folic acid can mask a vitamin B12 deficiency. Research suggests that high folate levels can even exacerbate the anemia and cognitive symptoms associated with a lack of vitamin B12. For these reasons, folic acid intake from fortified foods should not exceed 1,000 mcg in adults with a good overall health status.


Research has suggested that the consumption of alcohol may reduce vitamin B12 levels.

An older study indicated that moderate alcohol intake diminished vitamin B12 by 5% among “healthy, well-nourished, postmenopausal women.”

Alcohol-related liver disease may falsely increaseTrusted Source vitamin B12 test levels. People with alcohol use disorder may need supplements to correct vitamin B12 deficiency and anemia.

Foods with insufficient vitamin B12

Some people believe that certain plant-based foods are good sources of vitamin B12. These foods include:

  • spirulina
  • dried nori
  • barley grass
  • other seaweeds
  • raw foods

However, many researchers believe that these foods are not adequate to correct a deficiency of vitamin B12. For instance, the vitamin B12 in cyanobacteria, such as spirulina, has very low bioavailability.

Therefore, although people can include the above foods as part of a healthful diet, they should not rely on them as a source of vitamin B12.

How to get vitamin b12 naturally

To increase the amount of vitamin B12 in your diet, eat more of foods that contain it, such as:

  1. Beef, liver, and chicken.
  2. Fish and shellfish such as trout, salmon, tuna fish, and clams.
  3. Fortified breakfast cereal.
  4. Low-fat milk, yogurt, and cheese.
  5. Eggs.

Top 10 Foods Highest in Vitamin B12 (Cobalamin)

Vitamin B12, or Cobalamin, is necessary for making DNA and for creating energy in our cells. (1) A deficiency of vitamin B12 leads to anemia, fatigue, mania, and depression. A long-term deficiency can cause permanent damage to the brain and central nervous system.

Vitamin B12 is created by bacteria and can only be found naturally in animal products, however, synthetic forms are widely available and added to many foods such as packaged cereals.

Vitamin B12 can be consumed in large doses since excess B12 is stored in the liver for use when supplies are scarce. Stores of B12 can last for several years, which is why it takes a long time before people realize they have a deficiency in their diet.

Foods You Should Eat if You Have a B12 Deficiency

All kinds of cells in your body need vitamin B12. That includes red blood cells and glial cells, the kind that protect your nerves. But you don’t make this nutrient on your own. You have to get it from outside sources. It occurs naturally in certain foods, like meat, dairy, and eggs. It’s also added to some foods.

On average, most people 14 and older need about 2.4 micrograms a day. The good news is your body stores extra B12 in your liver. If you stop absorbing it, it’ll take a few years to use what’s left. But once you do, you’ll likely have some health problems. These include fatigue, memory trouble, or nerve damage.

Treatment can help you get better. If you have a serious deficiency, your doctor will probably give you B12 through a shot in your muscle or a daily high-dose supplement. You may need to make changes to your diet, too. Boost your B12 levels with these foods.

Fish and Shellfish

This is how much B12 you’ll find in a 3-ounce serving of these foods:

  • Cooked clams: 84.1 micrograms
  • Steamed mussels: 20.4 micrograms
  • Cooked Atlantic mackerel: 16.1 micrograms
  • Steamed Alaska king crab: 9.8 micrograms
  • Cooked wild rainbow trout 5.4 micrograms
  • Cooked salmon: 2.4 micrograms

Red Meat

This includes beef and lamb. Like humans, large amounts of B12 are stored in their livers.

Here’s what you can get from 3-ounce servings of the following:

  • Cooked beef liver: 70.7 micrograms
  • Grilled lean beef, steak: 6.9 micrograms

Too much red meat can raise your chances for certain health conditions. That includes heart and blood vessel problems and certain kinds of cancer. You may want to limit it to a few servings a week. Ask your doctor how much is safe for you.


Cows also pass B12 into their milk. This is what you’ll find in the following:

  • Low-fat milk, 1 cup: 1.2 micrograms
  • Low-fat yogurt, 8 ounces: 1.2 micrograms
  • Swiss cheese, 1 ounces: 0.9 micrograms


You can find some B12 in chicken and turkey.

  • Cooked turkey liver, 3 ounces: 23.9 micrograms
  • Cooked chicken liver, 1 ounces: 4.7 micrograms
  • Cooked ground lean turkey, 3 ounces: 1.6 micrograms
  • Roasted turkey, 3 ounces: 0.8 micrograms
  • Roasted chicken breast, 3 ounces: 0.3 micrograms


One hard-boiled egg has about 0.6 micrograms of B12. That’s 25% of your daily value. But you’ll need to eat the whole egg. Most of the B12 comes from the yolk.

If you have a deficiency, eggs shouldn’t be your main source of B12. There’s not a lot of evidence that they can raise your levels of B12 all that much. 

Vegan or Vegetarian Sources

It’s harder to get your B12 from food if you’re on a strict plant-based diet. That means you don’t eat any animal products, including eggs or dairy. Your doctor will likely suggest taking a daily or weekly dietary supplement to keep your levels up. They can let you know what dose is right for you.

You can get B12 from some plant-based sources. These include fortified foods with added nutrients.

  • Fortified non-dairy milks, such as soy or oat, 1 cup: 0.6-2.07 micrograms
  • Fortified cereals, one serving: 0.6-2.1 micrograms
  • Nutritional yeast, 1 tablespoon: 4.8 micrograms

Always read the nutrition label to see how much B12 you’re getting per serving.

Some fermented foods and seaweed have B12. It comes from their exposure to bacteria. You shouldn’t depend on them for all your B12 needs. But you can still add them to your diet. They include:

Tempeh. This is a fermented soybean cake. Studies show that one serving may have anywhere from 0.7-8.0 micrograms. But it’s hard to know exactly how much you’ll get in the kind you find at the grocery store.

Nori. These are dried sheets of seaweed. You’ve probably seen them used to make sushi. Studies show it might be possible to get 2.4 micrograms of B12 from 4 grams of nori. But you’d need to eat a little more than 13 sheets to meet your daily intake. 

If you’ve been vegan or a strict vegetarian for more than a few years, ask your doctor to check your B12. A simple blood test can show if your levels are where they should be.

When Food Isn’t Enough

Treatment for your B12 deficiency depends on what’s causing it. Older age and certain health conditions, like pernicious anemia, can make it hard for your stomach to absorb B12 from food. Your doctor can run some tests to find out if you have these problems. You may need regular B12 shots or dietary supplements  to stay healthy.
