​What is Vitamin B12 & Why is It So Important?

elements illustrations

Vitamin B12 is a water-soluble vitamin required for many vital functions in the body, such as the production of healthy red blood cells and proper neurological function. You only need 2.4 micrograms of vitamin B12 per day – around three millionth of a gram (1) (2).

According to Dr. Jennifer Rooke from the Morehouse School of Medicine, both vegans and omnivores risk deficiency (3):

“animal products contain B12, and strict vegetarians/vegans are at risk for B12 deficiency, but absorbing B12 from animal products is a very complex process and people who eat meat may be at equal or greater risk for B12 deficiency.”


Do vegans really need b12 supplements?

Vegans need B12 supplements if they plan to continue their veganism long term. Right now, there are no noteworthy plant sources of vitamin B12 with high enough bioavailability to be considered as sustainable sources of the vitamin.

One study of 232 vegans found that half of them were categorized as deficient of this essential vitamin, concluding that it is largely missing from a vegan lifestyle (4).

​You can also get vitamin B12 from vegan multivitamins. This way, you are also provided with other nutrients that your body is probably lacking as well.


How much b12 should a vegan take?

A vegan should take 500-1000 mcg of B12 once every few days. Although the RDA by the Food and Nutrition Board for vitamin B12 is 2.4 micrograms per day, a significant portion of the B12 we consume is lost and our body doesn’t absorb it all (5).

As a result, 500 mcg only translates into about 10 mcg being absorbed. It’s difficult to take too much B12, so those living a vegan lifestyle should not be afraid to take high doses of this vitamin in the form of plant-based supplements (6).


What happens when your vitamin b12 is low?

When your vitamin B12 level is low, you may experience many negative effects. Pale skin, fatigue, mouth ulcers, dizziness, breathlessness, high temperatures, disturbed vision and mood swings are all tell-tale signs of a B12 deficiency.

B12 plays many important roles in your body’s nervous system and red blood cell production, so having too little B12 in your diet can take a toll on your body’s functioning.


Can vegans get b12 naturally?

Vegans can only get B12 naturally by consuming products that have been fortified with B12, such as certain brands of fortified almond milk and soy milk. Apart from that, vegans need to get their B12 by taking supplements.

Sadly, there are no reliable plant-based sources of B12 that are bioavailable enough to be noteworthy.


Which fruits and vegetables contain vitamin b12?

Plants such as mushrooms, chlorella, spirulina, and nori seaweed have been shown to contain some vitamin B12, however, these sources are known as B12 analogs, meaning that they are less potent or completely inactive (7) (8) (9) (10).

Some studies have suggested that plants, such as chlorella, may be able to provide a bioavailable form of vitamin B12, although the results were very varied, with different batches varying in their B12 content from zero to several hundred micrograms of B12. (11)

Plant-based B12 is hard to find, as Dr. Edward Group from the Global Healing Center explains (12):

“The majority of food sources for vitamin B-12 come from foods of animal origin, making vegan options somewhat limited. Certain soil bacteria synthesize B-12 and some people believe that eating unwashed vegetables may provide trace amounts of the vitamin. However, most people aren’t too keen on eating dirty vegetables.”

​​Is B12 Considered Unnatural on a Vegan Diet?

Supplement B12

First of all, as we’ve established B12 is not produced by animals, but by bacterial fermentation. Animals just have the capacity to absorb and accumulate B12 in their flesh and secretions.

Also, the B12 found in supplements is produced by the exact same bacterial activity as in the stomach of a ruminant or in soil – there’s literally no difference.

Secondly, back in the day, not the 70’s but tens of thousands of years ago, we lived in a more unhygienic environment compared to today’s modern society.

If you lived 150.000 years ago, you were probably drinking dirty water, eating unwashed fruits and veggies, unintentionally eating your own and others feces – all of which contribute to meeting B12 needs.

Considering that our requirements are microscopic, only a few micrograms per day, it makes sense that this would supply the tiny amount that’s required.

And even if it was the case that our ancestors relied on meat for B12 tens of thousands of years ago, exactly what relevance does that have for us right now? None.

It’s also practiced to give sheep and cattle supplemental B12 in order for them to reach optimal levels, which means meat-eaters are indirectly supplementing B12 by eating animal products.

Wouldn’t it make a lot more sense to get B12 directly from a supplement, instead of it having to pass all the way through a cow or pig or sheep that then has to die?

Cyanocobalamin Vs. Methylcobalamin

There are mainly two different forms of B12 available on the market:

  • Cyanocobalamin
  • Methylcobalamin

Cyanocobalamin is bound to a cyanide molecule, and methylcobalamin is bound to methyl group of carbon and hydrogen. The most common form found in supplements is cyanocobalamin.

However, it’s been proposed that methylcobalamin is the superior alternative due to certain factors. 

The theory is that the body absorbs vitamin B12 as cobalamin, but it must then further converted to a coenzyme form, methylcobalamin, to become metabolically active. B12, in the form of methylcobalamine, is bioidentical to the active form found in the body – basically making it more “body-ready” than other forms of B12.

Furthermore, some concerns have been raised in regards to exposing the body to cyanide by using cyanocobalamin. However this is not something you should worry about: many different foods you eat on a daily basis, such as flax seeds, contain small amounts of natural cyanide and the body is capable of dealing with this.

Now, what does the research say on the subject?

One paper from 2015 examined the various forms of vitamin B12 and concluded that: There was no benefit of using methylcobalamin over cyanocobalamin in terms of bioavailability, biochemical effects, or clinical efficacy (13).

Bottom line is that it doesn’t seem to matter much which form of B12 you choose because both work rather well. To ensure optimal uptake you could alternate between the different forms (probably overkill).

It also doesn’t seem to matter whether you go with a sublingual, meaning dissolved under the tongue, or normal pill that you swallow (14).


FAQ & Buyer’s Guide

Vitamin B12 Supplement FAQs

What are the side effects of too much vitamin b12?

Having too much vitamin B12 can have side effects such as breakouts of acne and rosacea, a skin condition that causes a red rash on your face. Too much vitamin B12 has also been linked to health problems for people suffering from kidney disease or diabetes. However, most people will never take doses high enough to cause these effects.

What is the normal range for b12 levels?

The normal range for B12 levels in your blood is 200-900 (ng/mL). If your B12 levels are below 200 (ng/mL) or above 900 (ng/mL), you may need to speak to your physician about changing your vitamin B12 intake. Too much or too little B12 can cause various health and energy problems.

What is the normal range for b12 levels?

Pepsin helps with B12 absorption. Pepsin is an enzyme which helps to break proteins down into their amino acids, aiding with B12 uptake. Intrinsic Factor, a protein, also helps to absorb B12 in your stomach lining. Sublingual supplements also help absorption, as they bypass the stomach where the B12 is often destroyed.

What is the best way for a vegan to get B12?

The best way for a vegan to get B12 is to add fortified foods with B12 to their diet. Plant-based milk, soy products, and cereals are the most common options.

What are vegan B12 supplements made from?

Vegan B12 supplements are usually made by isolating the B12 from bacterial cultures that naturally produce it. The only other option is to extract it from animal products.
