Vitamin B12 on a Plant-Based Diet

A plant-based diet can provide all the nutrients the human body needs to thrive, with the curious exception of vitamin B12. Neither plants nor animals directly produce vitamin B12. It’s produced by microbes that grow all over the earth’s surface and inside guts of animals, which is why meat is a common source of B12. Plant eaters would get plenty of B12 if they continued to eat unwashed food and dirt, but since most people don’t eat this way, they need to get creative.

Without B12 you’ll feel tired, sad and confused.

B12 is responsible for a host of functions, including red blood cell formation, DNA synthesis, and energy metabolism. Vitamin B12 deficiency symptoms include fatigue, weakness, confusion, and soreness of the mouth. Deficiency can also lead to severe health conditions, such as anemia, dementia, and depression.

While B12 supplementation is a perfectly good option to prevent deficiency, there is also a variety of B12-fortified foods on the market that can help you meet the 4-7 micro gram per day recommendation. Common plant-based foods fortified with B12 include:

  • Plant-based milks such as soy milk, coconut milk, and nut milks, although not all brands and varieties are fortified.
  • Vegan meat substitutes, such as Yves brand deli slices and ground faux meats.
  • Tofu, although the Nasoya Organic Firm variety appears to be one of the few brands that contain B12.
  • Some brands and varieties of cereals. Non-dairy, high-fiber, and low added sugar options include Kellogg’s All Bran and Special K, and General Mills Cheerios and Fiber One cereal varieties.

Try these tasty options.

One of the best plant-based sources of Vitamin B12 is nutritional yeast. This inactive form of yeast, which can be found in the bulk foods, health foods, or organic sections of most grocery stores, contains 40% of the recommended dietary allowance for vitamin B12 per tablespoon.

Nutritional yeast can be used in all types of recipes to add a slight cheese-like flavor. Add a tablespoon or two to salsas, dips, spreads, and sauces. Here are two quick, easy, and healthy recipes that incorporate nutritional yeast.
