Do You Need A Vegan Vitamin B12 Supplement?
In a word – yes.
Even though you don’t need one immediately after going vegan or vegetarian (Your body’s vitamin B stores can last for multiple years), you will want to get a supplement at some point because B12 is an essential nutrient. In typical western vegan diets, you won’t get much vitamin B12 from foods themselves (although some are fortified with B12), and a supplement is more of a guarantee anyways.
B12 needed to make red blood cells, and supports your brain and nerve function (among other roles).
A vitamin B12 deficiency can lead to serious problems like anemia and neurological disorders. Research has shown a link between low B12 levels and Alzheimer’s disease and heart disease (1, 2).
You can also consider getting a multivitamin instead, which all contain B12 and other useful nutrients for about the same price. Here’s a list of the best vegan multivitamins if you want to take that route instead.
What to Look for in a Vitamin B12 Supplement for a Vegan
There are a few things that make finding a vitamin B12 supplement confusing:
- There are both vegan and non-vegan B12 supplements.
- There are 4 main different forms of B12.
- Some supplements have doses of 1000%+ of your daily value
I’ll answer these questions as briefly and simply as possible so we can get to the actual products.
Why Are There Non-Vegan Vitamin B12 Supplements? (And how do you spot them?)
All vitamin B12 is made by bacteria or archaea (3).
Animals eat these organisms, mainly in the dirt of plants (we just clean our plants well). Then, they absorb any B12 that the bacteria produces and it’s stored in their bodies. This is why meat eaters don’t need to worry about B12 levels.
The problem is that by the time those bacteria pass through a human’s small intestine, we can’t absorb any B12 they produce. That’s why vegans need to take supplements of already formed B12.
Some supplement manufacturers use bacteria as sources of vitamin B12 in labs (suitable for vegetarians or a vegan diet), while others extract it from animals (non-vegan).
Another issue, is that some companies package B12 as softgels (which have gelatin). For example, Nature’s Made B12 isn’t vegan.
Most vegan B12 supplements will clearly state that they are vegetarian or vegan, which means they are made from bacteria (vegetarian is equivalent in this situation).
Which Type of Vitamin B12 Supplement is Best for Vegans?
B12 can actually take multiple forms (in terms of chemical structure), some are easier to absorb than others.
Here are the main 4:
- Cyanocobalamin – A synthetic form, made in a lab. But is harder for the body to absorb and takes more energy to convert it to a more usable form.
- Methylcobalamin – A synthetic form, made in a lab by modifying cyanocobalamin. It’s the most easily usable form of B12. It’s what most vegan supplements are made from.
- Hydroxocobalamin – The most “natural” form of B12, found in animal products. The body later converts this to methylcobalamin. It’s used to treat cyanide poisoning and B12 deficiency in medical settings.
- Adenosylcobalamin – The least stable form of B12, rarely used in supplements.
The type is usually clearly labeled in multiple places on the product label:
Does it matter which type a supplement uses? It doesn’t make a huge difference either way, but we’re looking for the first 2 types (cyanocobalamin or methylcobalamin).
What Dosage is Ideal for Vegan Vitamin B12 Supplements?
Some supplements have a few micrograms (mcg) of B12, while others have thousands of micrograms. They often cost a similar amount.
What’s the deal?
The recommended daily allowance (RDA) of vitamin B12 is 2.4 mcg. That’s a very small intake.
It’s easy to put a lot more than the RDA in a supplement without much extra cost (in fact it can be cheaper).
Since it’s a water soluble vitamin, your body just doesn’t absorb much excess from a supplement. In fact, your body only absorbs about 13 mcg from a 1,000 mcg B12 supplement.
Currently, there’s no upper daily intake level set for B12, and studies have shown that intake of daily oral supplements of up to 2 mg (2,000 mcg) are safe and effective in treating B12 deficiency (4).
There is weak evidence that having to much could increase risk of heart attack and stroke (5). So maybe avoid mega high doses, but for the most part you don’t have to worry about overdoing it.
One final thing to consider is that high doses of vitamin B12 trigger acne in some people. If you’re worried about that, stick to a supplement on the lower end of the range.
Vitamin B12 has a very low absorption rate. Any excess vitamin B12 won’t be absorbed, so don’t worry about getting too much if there are a few thousand micrograms per serving.
The Best Vitamin B12 Supplements for Vegans
So from everything above, we’re looking for a B12 supplement that is:
- Clearly labeled vegan (or vegetarian).
- Somewhere around 1,000-2,000 mcg (micrograms), equivalent to 2 mg, is typically most convenient.
- Methylcobalamin is ideal, it’s the easiest form to absorb (but others are okay). All of the products on this page are methylcobalamin.
- It’s not critical in most cases, but taking vitamin B12 supplements without food can increase absorption.
Recall that the RDA is 2 mcg (way less than a serving of most supplements), I’ll use mcg exclusively from here on to make it easier.
All of these supplements are good, and they’re in order of what I think is the best. The best vegan vitamin B12 supplement will depend on your budget and how you’d like to take them.
1. Future Kind Vegan B12 Chewable Supplement
B12 in serving: 1,000 mcg
Cost per serving: $$$
- Great flavor
- Chewable tablets are easy to consume
- No sugar
- Amount of B12 per serving is a bit on the high side for some people
Future Kind is probably my favorite overall vegan vitamin brand. They only make vegan products, and seem to always use the highest quality ingredients in proper dosages.
Everyone has their own preferences, so if you really can’t do capsules or tablets, Future Kind also sells vegan vitamin B12 gummies. However, these only have 500 mcg per gummy, along with a small amount of sugar, so they’re less ideal.
2. Garden of Life Vitamin Code Raw B12 Whole Food Supplement
B12 in serving: 1,000 mcg
Cost per serving: $$$$
- Vegan certified
- Contains probiotics and digestive enzymes
- Amount of B12 per serving is on the high side
Garden of Life is a very reputable brand who makes a wide variety of vegan supplements.
However, it’s the most expensive of any of these options by far.
These are standard sizes pills, which are fine for most people. If you have a hard time swallowing pills, choose a different option.
There’s 1,000 mcg per pill, and having once a day is more than enough to ensure that you have healthy B12 levels.
3. EZ Melts B12 Supplement
B12 in serving: 2,500 mcg
Cost per serving: $$
- Tastes pretty good
- No sugar (sweetened with the sugar alcohol mannitol)
- Relatively cheap
- Amount of B12 per serving is very high
This B12 supplement has 2,500 mcg per serving, so you only need to have it every day or two.
Instead of a pill, these are dissolvable, cherry flavored tablets that “melts” quickly in your mouth.
Note that the cost is relatively cheap per serving, and if you’re not having it every day, it’s even cheaper than the other “daily” options on this list.
4. Zhou Methyl B12 Supplement
B12 in serving: 5,000 mcg
Cost per serving: $$
- Very small capsules
- Relatively cheap
- Very high amount of B12 per serving
Note that it has 5,000 mcg per serving, so having this once or twice a week will keep your levels topped up.
Another advantage is that these capsules are micro-lozenges, which are about half the size of a normal lozenge. It will dissolve quickly in your mouth.
It’s sweetened with a sugar alcohol as well, xylitol in this case.
5. Deva Vegan Vitamin B-12
B12 in serving: 1000 mcg
Cost per serving: $
- Convenient dissolvable lozenges
- Relatively cheap
- Quite a few complaints about expired products being shipped
Deva is another well-known brand that makes a wide range of vegan supplements. It’s also the cheapest one on this list per serving.
This is a daily B12 supplement, you should have 1 per day according to the label, which seems about right.
These are also lozenges that dissolve in your mouth (normal sized), and sweetened with xylitol.
One More Option for Costco Members
It’s not clearly stated on the bottle whether or not Kirkland’s B12 is vegan.
I contacted customer support and found out that Kirkland’s vitamin B12 supplements are indeed vegan. It’s probably the cheapest option for vegans that shop at Costco.
Which B12 Supplement is Best For You?
The whole B12 issue is made out to be more complicated than it really is.
Yes, if you lived in the wild, you would need to get B12 from meat in most cases because it’s an essential nutrient, but we don’t live in the wild any more.
Any of the supplements on this page will be great for a vegan. You can also find vegan B12 supplements in many local drugstores (and now you should know what to look for).
Pick one based on how often you’re willing to take a supplement, and what type of capsule (pill or lozenge) you prefer.
And while vitamin B12 supplements are important for vegans, it’s hard to go wrong.
If you’re really against taking a supplement, you should regularly eat vegan foods that are fortified with B12 (e.g. breakfast cereals). It’s extra important to regularly get blood tests to check vitamin B levels if you take this approach.
How Much Vitamin B12 Is Absorbed From Supplements? [Data]
When you look at most vegan vitamin B12 supplements, they have serving sizes over 1,000 mcg (1 gram), even though the RDA of B12 for an adult is only 2.4 mcg.
According to a study that looked at how much B12 is absorbed by the body, the amount depends on the dose.
They found that 56% of a 1 mcg dose was absorbed, but the percentage went down as the dose increased.
Here’s a table of their findings.
For a 1,000 mcg serving, which is pretty typical in supplements, approximately 1.3%, or 13 mcg is absorbed.
This is still well over the RDA, which is why you don’t necessarily have to take these religiously every day (even if the bottle might recommend it).
Keep in mind this assumed that your body is healthy and you don’t suffer from malabsorptive disease.
If you have any other questions, leave them below and I’ll try to answer.
Why Do B12 Supplements Have Other Minerals or Vitamins Added to Them?
There’s no specific reason as far as I can tell to add other ingredients. Other than folic acid (not typically added), none of them improve absorption in any way.
It’s just for convenience in case you also wanted to take other dietary supplements like iron or vitamin D, which people on a plant based diet often do (even if they aren’t mandatory like B12 is).
The supplements on this page are “just” B12 with no other added vitamins and minerals.
Standard disclaimer: I’m not a doctor, and this isn’t medical advice. If you suspect you have a vitamin B12 deficiency, go see a doctor and get professional advice. It’s possible you have an issue like an intrinsic factor deficiency, and can’t properly absorb B12. Or, you could folate deficiency anemia, which causes your body to produce abnormally large blood cells.
