Which vegan B12 supplements are best?

Vitamin B12 is an essential nutrient crucial for healthy nerve function and red blood-cell formation. Because it is only found in animal-based foods, most vegans and vegetarians don’t get enough in their plant-based diets, and a B12 deficiency can lead to health issues like anemia. So the Mayo Clinic suggests they, as well as older adults, should take a daily supplement to meet the recommended amount. 

New Chapter Fermented Vitamin B12 Supplement is the recommended pick for a B12 supplement because it is certified organic, vegan and gluten-free. 

What to know before you buy a vegan B12 supplement

Signs of a vitamin B12 deficiency

People with a B12 deficiency may experience fatigue, yellow skin, dizziness and even mental confusion in serious cases. The signs of vitamin deficiency can take a while to develop, so if you’re a vegetarian, vegan or an older adult, consider taking a supplement even if you are not experiencing any of these symptoms. 

How is vegan B12 made? 

Despite its presence in many animal-based foods, vitamin B12 itself is vegan by nature. That is because it is naturally produced by certain bacteria that live in the stomachs of many animals, but not plants or people. Scientists take the bacteria and let them produce the nutrient in a lab setting, thereby producing a source of B12 without the involvement of animals. This means that B12 supplements are naturally vegan unless they contain animal byproducts. 

Commonly used animal byproducts

If you’re avoiding animal products but you can’t immediately tell if a supplement is vegan, check the list of inactive ingredients for these commonly used animal-derived products. 

  • Gelatin: Perhaps the most common animal byproduct used in supplements, this gel-like substance is often used as a coating or filler in pills and capsules. 
  • Magnesium stearate: Another ingredient used as a filler for many supplements, magnesium stearate is derived from animal fat. This ingredient can also be made from plants, but that will usually be specified on the product’s packaging. 
  • Lanolin: This isn’t typically found in B12 supplements unless they also contain vitamin D. Lanolin is usually derived from sheep. 
  • Bee pollen: This is occasionally used in B12 supplements to provide an additional energy boost. It’s considered an animal product because it’s derived from bees. 

What to look for in quality vegan B12 supplements


Like other vitamins, vegan B12 supplements can be sold in a variety of different forms, including capsules, gummies, even oral sprays. You can also find powders to mix into your favorite drinks or smoothies. 

Third-party certifications

Watch out for products that are solely marketed as “vegan-friendly” or “plant-based”. The only way to know for sure if a supplement is vegan is to verify that it has been certified by a third-party organization like People for the Ethical Treatment of Animals or Vegan Action. This is also true for products advertised as organic or cruelty-free. 


The recommended dosage can vary depending on the person, but the National Institutes of Health recommend at least 2.4 micrograms per day for most adults. Higher doses are generally considered safe and are often recommended for people with deficiencies. 

How much you can expect to spend on a vegan B12 supplement

The cost of a vegan B12 supplement usually depends on the number of doses in the container. Expect to spend around $10-$30 for a medium-sized container.
