Vegans and B12

“But don’t you need to eat meat to get your Vitamin B12?”

Absolutely not.

Did you know that bacteria are responsible for producing B12?

In fact:

“All of the Vitamin B12 in the world ultimately comes from bacteria.  Neither plants nor animals can synthesize it.  But plants can be contaminated with B12 when they come in contact with soil bacteria that produce it.  Animal foods are rich in B12 only because animals eat foods that are contaminated with it or because bacteria living in an animal’s intestines make it.”

—From The Vegetarian Way: Total Health for You and Your Family (1996), Virginia Messina, MPH, RD, & Mark Messina, PhD p. 102

Now that’s food for thought!

So where can vegans get their B12? It’s in fortified foods (like cereals and energy bars), tempehseaweed, miso, nutritional yeast, spirulina, organic produce, and soil on unwashed vegetables.

There are also plenty of vitamin supplements you can choose from to meet your daily requirement—some in the form of candy even. :)

Just keepin’ it real,

    If I can’t afford it to get my B12 levels checked, is it OK to take supplements? Also, is there such a thing as too much B12?

    i had a full blood work up recently and had perfect levels of everything including high iron, high B12 and low cholesterol. my doctor seemed a little frustrated my nutritional status is so good as a vegan!

    nutritional yeast is not only easy and convenient, it tastes great. i even share mine with my dogs :-)

    We have it naturally – no need to consume it.

    This is SO important for vegans to know! I like to throw a ton of b-12 fortified nutritional yeast on just about everything I eat. I also take a sublingual b-12 supplement every other day just to be safe.

    I am 13 years old and joined the street team June 2015. I am a vegetarian. I have a passion for working to help save animals. I love my family and my 2 pugs, Daisy and Diesel. I plan to work for Peta or Mercy For Animals someday because they helped me become a vegetarian and begin a whole new life of having common sense towards all animals.
