One of the best sources of B12 for vegans and vegetarians is nutritional yeast.
Other vegan-friendly foods with B12 include nori and shiitake mushrooms.
Fortified foods like coconut milk and soy milk are also great B12 options for vegans.
Vitamin B12 is one of the most difficult vitamins for vegans to get because it exists primarily in animal products like meat and dairy.
It's important to get enough vitamin B12 in your diet because B12 has many health benefits including helping the body form nerve and red blood cells. And a vitamin B12 deficiency can lead to fatigue, constipation, and weakness.
If you are a vegan and looking for some ways to incorporate vitamin B12 into your diet here are four vegan-friendly food options:
1. Fortified foods
Fortified foods are foods that have vitamins or minerals added to them that they normally do not contain. Food manufacturers and government agencies like the Food and Drug Administration work together to fortify foods as a way to address nutrient deficiencies within populations.
Some examples of vegan-friendly foods fortified with vitamin B-12 include:
Breakfast cereal, like Kellogg's All-Bran: one serving contains 11.7 mcg of vitamin B12 or about 480% of your daily value.
Fortified soy milk, chocolate: 1.7 mcg of B12, or about 70% of your daily value
Fortified coconut milk: one cup contains 3 mcg of vitamin B12, or about 125% of your daily value.
Studies are mixed as to whether or not the B12 in nori is beneficial to humans. "Some [studies] showed nori containing the active vitamin B12, while others found nori containing exclusively pseudo-B12, which are not active in humans," says Roman M Pawlak, PhD, RDN, an associate professor at East Carolina University.
Pawlak says vegans should incorporate a variety of foods in their diet to reach their daily B12 requirements. So, while you shouldn't write nori off, don't rely on it for all your B12 needs.
Nori can be easy to incorporate into your diet. Jeff Gilis, MFN, RDN, NCSF-CPT, a lecturer in the department of nutrition and dietetics at the University of Northern Colorado says some vegan-friendly meals and snacks with nori include:
Vegan sushi rolls such as avocado, cucumber, or sweet potato rolls
Substitute dried seaweed packets in place of chips or pretzels
Add dried nori flakes to vegan poke bowls or rice
3. Nutritional yeast
Nutritional yeast is a member of the fungus kingdom and is vegan-friendly. It's a form of deactivated yeast — meaning it's similar to the yeast used in bread baking but it is no longer alive — says Pawlak. It can be found in most grocery stores in either powder, granule, or flake format.
"[It] has a cheesy flavor, most closely resembling parmesan cheese, so using it with Italian dishes works quite well. It can also be used in making plant-based "cheese" sauces to provide more of the cheesy-type of flavor that you typically look for," says Gilis.
4. Shiitake mushrooms
One hundred grams of shiitake mushrooms contain an average of 5.6 mcg (230% DV) of vitamin B12, making it a good option for both vegans and vegetarians.
"These are easily incorporated into various dishes, depending on the person's preferences," says Gilis.
Some meals that can be enhanced by shiitake mushrooms' umami flavor include:
You can even sautee them alone as a quick snack.
Should vegans take a B12 supplement?
According to the National Institute of Health, the daily recommended dose of vitamin B12 is as follows:
