Vegan Sources of B12

Let’s go ahead and take a look at the different vegan sources. These foods contain Vitamin B12 which can help prevent Vitamin B12 deficiency.

Nutritional Yeast

Nutritional Yeast as a source of Vitamin B12 for vegans is one of the most popular foods for vegans and vegetarians alike because it is known to be a powerful source of B vitamins, including B12. Just two tablespoons of nutritional yeast will give you the recommended daily value for Vitamin B12.

Moreover, nutritional yeast as one of the vegan sources of B12 is low in calories and fat but high in fiber which is good for digestion. It also contains other essential minerals like selenium and zinc.

You can find nutritional yeast in most health food stores. It is usually sold in flakes or as a powder. You can add it to different recipes for an extra cheesy flavor.


Tempeh is a fermented soy product that originates from Indonesia. It is made by culturing soybeans with a rhizopus mold. This results in a cake-like texture that can be used as a meat alternative.

Tempeh is an excellent source of protein, fiber, and vitamins. It also contains Vitamin B12. Half a cup of tempeh will give you the recommended daily value for Vitamin B12.

Marmite + Yeast Spreads

Marmite plus Yeast Spreads are another good source of Vitamin B12. The taste is not for everyone but you can experiment and check if this will work for you. The combination usually yields 0.5mcg of Vitamin B12 for every 100 grams.

Fortified Soy + Almond Milk

Looking for foods for a plant-based diet with B12, another good option for vegans is the combination of fortified soy and almond milk. You will usually find this type of milk in the stores with a “fortified with B12” label.

Make sure to check the nutrition label before purchasing as some brands add Vitamin D instead of B12. A good rule of thumb is to choose the brands that have 2.5 micrograms or more per serving.

Plant-Based Meats

There are also plant-based meats that contain B12 as a good alternative for vegans and vegetarians to get enough B12. Not all plant-based meats are fortified with B12 so check the nutritional value if you buy one to make sure that the plant-based meat is a reliable source of B12.
