Where Does Vitamin B12 Come From in Food?

W

Vitamin B12 is the only essential vitamin or mineral that vegans can’t really get naturally. The best food sources overall are animal products. But while most people think that vitamin B12 is produced by animals, they’re wrong. It’s in fact produced by certain bacteria and archaea, which are both single-celled microorganisms. Animals ingest the B12 made from these and absorb them, just as humans...

Is Nature’s Made B12 Vegan

I

Nature’s Made is a fairly popular vegan supplement brand who makes several B12 supplements. Some of their supplements may be vegan, but none of Nature’s Made B12 is definitely vegan. Let me explain. First, the soft gels are 100% NOT vegan. These contain not only gelatin (not vegan), but also beeswax. You can see the other ingredients on the nutrition label. The normal B12...

Is Kirkland Vitamin B12 Vegan? (I contacted them to find out)

I

I remember the first time I went to Costco after going vegan, and I spent about 15 minutes trying to look up whether or not the Kirkland vitamin B12 supplements were vegan friendly or not. The packaging is unclear, but the fact that the B12 is in the form of methylcobalamin is a good sign, because that form is usually made in a lab. I simply bought other supplements after giving up. But that all...

Why Vegans Are At Higher Risk for B12 Deficiency – And How to Prevent It

W

The only thing that you can’t get from whole foods on a typical vegan diet is vitamin B12. Considering that a decent portion of the general population is already B12 deficient, it’s even worse for us vegans. B12 is used by the body to make and maintain important things like red blood cells, nerves, and DNA (among others). It’s very important. If you’re significantly deficient in B12, you...

How Much Vitamin B12 Is Actually Absorbed From Supplements?

H

Most vegans get their vitamin B12 through supplements. 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...

Is Vitamin B12 Destroyed by Heat or Light?

I

If you rely on vegan food sources of vitamin B12 like granola or nooch (nutritional yeast), it’s pretty smart to be wondering if B12 gets destroyed in the cooking process by heat. The good news is that B12 is fairly tough. It’s resistant to PH changes (acidity level), so combining it with lemon juice or any food with significant acidity won’t have much of an effect on it. However, Vitamin B12...

How Long After Going Vegan Should I Start Taking Vitamin B12 Supplements?

H

Vitamin B12 is the only “mandatory” supplement that vegans need to take. Because of where humans get B12 naturally, vegans don’t tend to get much (if any) from whole food sources. People in general get most of their B12 from animal products. The good news is that your body can store a lot of it. Depending on your size, you can store between 2,000 and 4,000 micrograms (mcg) in your body, mainly in...

Where Do Humans Get Vitamin B12 Naturally?

W

Despite what some people believe, it’s possible to eat a completely vegan diet without supplements. Most of us vegans need a good vegan vitamin B12 supplement, but that’s because of how our food is cleaned. Vitamin B12 is made by bacteria or archaea (a single-celled organism). This bacteria usually hangs out in the dirt that plants (vegetables) grow in. So in the past, when people ate plants...

How Are Vegan B12 Supplements Made?

H

Vitamin B12 is crucial for a healthy nervous system. Short term deficiency leads to fatigue and tingling in the hands and feet. If you’re deficient in it for long enough, it can result in permanent damage like dementia, blindness, and more. It’s also the one nutrient that you can’t get naturally on a first world vegan diet. That’s why we need to use B12 supplements. To understand why some vitamin...

T

“You’re going to die! You can’t get vitamin B12 as a vegan!” True, vitamin B12 is important. It’s needed to make red blood cells, and supports your brain and nerve function (among other roles). And it’s true that on typical western diets, you won’t get much (if any) vitamin B12. The issue is blown way out of proportion. Your body’s vitamin B stores can last for multiple years, because you don’t...
