Vitamin B12 is an essential B vitamin that our bodies need every day.
B12 helps turn the food you eat into usable energy.†
There are a variety of foods that contain B12, the most common being animal products (meat, fish, eggs, dairy) along with a few plant-based sources.
Vegetarians and vegans that do not consume animal products might want to consider a vitamin B12 supplement.†
If you are wondering how to get vitamin B12 naturally, then this is the blog for you! Vitamin B12 is found in many food sources, although most of them are animal-based. If you are vegetarian or vegan, there are foods available that will provide some vitamin B12 for your nutrient needs. However, those who don’t consume animal products, as well as pregnant and lactating women and older adults, should consult with a healthcare provider to determine their vitamin B12 level to check for possible B12 deficiency▲ and see if they are getting enough of this important vitamin.†
What is the Recommended Vitamin B12 Intake?
Before we dive into what foods have vitamin B12, it’s helpful to know how much B12 you should consume daily. The Recommended Dietary Allowance (RDA) of vitamin B12 is set by the Food and Nutrition Board at the Health and Medicine Division of the National Academies. This recommended daily intake changes by age, so we included a chart so you can find the minimum amount you should consume daily in your diet :
Now that we know the amount of vitamin B12 that we should consume in a day, let’s examine a list of foods that naturally contain vitamin B12 from most to least abundant and we’ll compare those amounts to the Daily Value (DV) for B12:
Liver and organ meats. While not appetizing to everyone, animal organ meats (liver, kidneys) are the most nutrient-dense foods. They are not only high in protein but also packed with iron and vitamin B6 (folate). One 3 oz serving of beef liver, for example, contains 70.7 mcg of vitamin B12, which is just under 3000% of the Daily Value (DV) .
These small shellfish are known for their chewy texture and are often used in soups and chowders. When eaten cooked and out of the shell, a 3 oz. serving of clams will provide 17 mcg of B12, which is just over 700% Daily Value (DV). Clams are also a good source of iron and antioxidants .
Tuna. Tuna is not only a good source of the Omega-3 fatty acids DHA and EPA, but it is also high in vitamin B12. One serving (3 oz.) of bluefin tuna will yield about 9.3 mcg at 385% Daily Value (DV) . Canned tuna is also a good option, with one 5 oz can providing 3.65 mcg of vitamin B12, which is still above the Daily Value for this nutrient .
Salmon is sometimes thought of as the superfood of the sea. This fatty fish is particularly high in Omega-3s and protein and is versatile enough to go into a variety of dishes. A 3 oz portion of cooked salmon provides about 2.6 mcg of vitamin B12, which meets Daily Value at 108% .
Beef. Red meat is a solid choice for vitamin B12, as well as many other types of vitamin B, although it is best consumed in moderation as part of a healthy diet. For a 3 oz. serving of ground beef (85% lean, 15% fat) you’ll get about 2.4 mcg of B12, which is right at the RDA for those 14 years and older and also at 100% Daily Value . If you were to consume a 3.5 oz serving of a porterhouse steak, then the vitamin B12 level is about 2 mcg .
Milk, yogurt & cheese. Dairy products are viable sources of vitamin B12 and a good choice for those Lacto-vegetarians that consume dairy as part of their diet. Even though the suggested serving sizes provide less than the RDA for B12, you can increase your ingestion of this vital nutrient throughout the day to meet your recommended amount. Here’s a quick breakdown of vitamin B12 amounts per serving: one cup of 2% milk contains 1.3 mcg (54% DV), 1.5 oz. of cheddar cheese contains 0.5 mcg (19% DV), and one 6 oz. container of low-fat yogurt contains 1 mcg (43% DV) . There is good news, however. Some studies suggest that our body may absorb vitamin B12 at higher rates from dairy products than from red meat or eggs . Something to consider.
Eggs. The good and bad about relying on eggs for vitamin B12: while they do contain this important B vitamin, it’s mostly found in the egg yolk, and as stated above, the absorption rate by your body is lower than from dairy . One large egg contains 0.5 mcg of vitamin B12 (19% DV) .
Turkey & chicken. A 3 oz. serving of turkey breast meat provides 0.3 mcg and one piece of a boneless, skinless chicken breast (6 oz.) also provides 0.3 mcg of vitamin B12 [1, 2]. That’s about 14% of the Daily Value and definitely not as high as beef. However, since it’s recommended to limit your servings of red meat to once or twice a week, including chicken and turkey in your diet can help provide some vitamin B12.
We haven’t forgotten about vegetarians and vegans! Despite what you might have heard, there are some plant-based sources of vitamin B12. However, you’ll see the list is not as long and varied as the animal-based list, which is why supplementing with vitamin B12 may be important for diets that are low in animal products. Read on to see how you can find B12 in the plant world:
Nutritional yeast. You might think of bread when you think of yeast. Nutritional yeast is specially grown to be used as food, not as a leavening agent in bread. This type of yeast is large and flaky with a nutty flavor and is usually used by vegans to mimic the flavor of cheese. Some nutritional yeast products are fortified with a variety of nutrients, including vitamin B12. One-quarter cup (15g) of fortified nutritional yeast can yield between 8.3 to 24 mcg of vitamin B12 depending on the brand. Either way, those amounts are well above the Daily Value . Nutritional yeast can easily be added to potatoes, pasta, and egg dishes, and it even tastes great sprinkled on salads.
Fortified foods. The practice of fortifying foods with added vitamins and minerals began in the early 1900s in the United States (and in other parts of the world) to address identified nutrient deficits in the population . Although a diet heavy in processed foods is not ideal, there are some vegetarian and vegan-friendly foods, such as whole-grain breakfast cereals and non-dairy milk, that are fortified with vitamin B12 along with other vital nutrients like Calcium and vitamin D. Most fortified foods contain up to 25% (0.6 mcg) of the Daily Value for vitamin B12 per serving .
Tempeh. This vegan-friendly food is made from fermented soybeans, and its stiff texture makes it an easy meat substitute in a variety of dishes. A one-half cup serving of tempeh provides 0.1 mcg of vitamin B12. That’s only 3% of the Daily Value, however, tempeh is also a good source of protein .
Dried shiitake mushrooms. Most mushroom varieties do not contain detectable levels of vitamin B12. However, shiitake mushrooms, when dried, have about 2.4 mcg of vitamin B12 for a one-quarter cup serving (50g), which would meet 100% Daily Value . Adding dried mushrooms to soups and stews provides a strong umami flavor. To prepare, soak dried shiitake mushrooms in warm water to soften and then discard the stems.
Vitamin B12 is an essential B vitamin that your body needs every day. The daily value, as used on food and dietary supplement labels, for vitamin B12 is 2.4 mcg for adults, but recommended dietary amounts (RDA) are higher for pregnant and lactating women. Animal-based foods are the most abundant source of vitamin B12, however, some fortified foods and plant-based foods also contain B12. Checking your vitamin B12 level with a healthcare provider is the first step in understanding if you are getting enough of this essential nutrient through your diet alone, and if you need to take a vitamin B12 dietary supplement. Supplementing with vitamin B12 may help reduce fatigue for those low in B12, so it’s a good idea to check your B12 levels with your healthcare provider.†
