The Importance of B12 for Vegans

Vitamin B12 is an essential nutrient that plays a critical role in many processes in the human body. It helps to create red blood cells, protect nerve cells, support brain function, and aid DNA synthesis. Unfortunately, it’s also a nutrient that many vegans struggle to get enough of.

Because B12 is primarily found in animal products like meat, dairy, and eggs, it’s often assumed that vegans are at a disadvantage when it comes to meeting their B12 needs. However, there are actually several vegan-friendly sources of this important vitamin. So what vegan food has B12?

Busting the Myth: Vegan Sources of B12

Contrary to popular belief, vegans can absolutely get enough B12 without consuming animal products. In fact, there are several plant-based options for obtaining this essential nutrient. One common way is through fortified foods.

Fortified foods are products with vitamins and minerals added during processing. Many plant milk (such as soy milk or almond milk), breakfast cereals (such as bran flakes or oatmeal), and nutritional yeast products are fortified with B12.

While the amount of fortification can vary by brand and product type, consuming these fortified foods regularly can help vegans meet their daily needs for this nutrient. Additionally, fermented foods like tempeh or miso contain bacteria that produce small amounts of B12 during fermentation.

Although not always reliable sources of the vitamin due to variability in production methods and amounts from batch-to-batch changes in microbial species composition, kimchi made with garlic may provide around 50% DV per serving size (1 cup). In sum: while there might be misinformation floating around about where we can obtain vitamin b-12 from, eating a variety of plant-based food options, including those fortified with nutrients like cereal grains or nutritional yeast supplements, along with fermented items such as kimchi, miso, and tempeh can help support a healthy vegan lifestyle.

Plant-based Foods Fortified with B12

As a vegan, it’s important to know that you don’t have to rely on animal products to get your daily dose of vitamin B12. Many plant-based foods are now fortified with this essential nutrient.

“Fortified” simply means that manufacturers have added extra vitamins and minerals to the food product during processing. Some common vegan foods that are often fortified with B12 include plant milk, breakfast cereals, and nutritional yeast.

In fact, you can easily find a wide variety of plant milk on the market that contains added B12. These may be made from soy, almonds, rice, or other nuts or grains.

Additionally, many breakfast cereals are now fortified with B12 as well, making for an easy and convenient breakfast option. But how much B12 do these fortified foods actually contain?

And how much do you need to consume to meet your daily requirements? The amount of B12 in fortified foods can vary widely depending on the brand and type of food.

For example, some brands of almond milk may only contain 25% of your daily recommended intake per serving, while others may contain up to 50%. It’s important to read labels carefully and choose products that provide at least 25-50% of your daily requirement per serving.

Meeting Daily Requirements

So how often should you consume these fortified foods to meet your daily requirement for B12? The answer depends on your individual needs and dietary habits.

Generally speaking, most adults need about 2.4 micrograms (mcg) of vitamin B12 daily. If you’re getting most of your B12 from fortified foods like plant milk or cereal, it’s recommended that you consume them at least twice a day to meet your daily requirement.

For example, if a serving of almond milk contains 30% of your daily requirement, you must consume at least two servings per day to reach 100%. It’s worth noting that some people may need higher doses of B12, particularly those who have trouble absorbing it or who follow a strictly plant-based diet.

In these cases, a supplement may be necessary in addition to fortified foods. It’s always a good idea to speak with your doctor or a registered dietitian if you have any questions or concerns about meeting your B12 needs on a vegan diet.

The Power of Fermentation

How Certain Bacteria Produce B12 During Fermentation

Fermented foods have been a part of human diets for thousands of years. They are a great source of nutrients, including vitamins and minerals, as well as beneficial bacteria.

It turns out that some of these bacteria can produce vitamin B12 during the fermentation process. Specifically, certain strains of lactobacillus and propionibacterium have been found to produce significant amounts of B12.

The process works like this: the bacteria use various substances (e.g., sugars) in the food as fuel to grow and reproduce. As they do so, they create byproducts such as organic acids and gases.

In some cases, they also produce vitamin B12 from precursor molecules that are present in the food or in their own metabolism. The resulting fermented food, therefore, has a higher concentration of B12 than the original unfermented version.

List of Vegan Fermented Foods That May Contain Significant Amounts Of B12

If you’re interested in getting your daily dose of vitamin B12 from fermented foods, consider several vegan options. Here are some examples: – Tempeh: A traditional Indonesian food made from soybeans that have been inoculated with a mold culture.

Tempeh has a nutty flavor and firm texture, making it popular among vegans as a source of protein. – Miso: A Japanese seasoning made from fermented soybeans (or other grains) with salt and koji (a type of mold).

Miso is commonly used to make soup or dressings. – Kimchi: A spicy Korean side dish made from fermented vegetables (usually cabbage) with chili powder and other seasonings.

Kimchi is known for its tangy flavor and probiotic benefits. Note that not all fermented foods contain significant amounts of vitamin B12, and the amount can vary widely depending on factors such as the type of bacteria used, the fermentation time, and the specific food being fermented.

To meet your daily requirement of B12 (which is around 2.4 micrograms for adults), you may need to consume relatively large amounts of these foods. It’s also possible that your body may not absorb the vitamin B12 from fermented foods as efficiently as it would from other sources, so it’s a good idea to supplement with a reliable source of B12 or get your levels checked regularly by a healthcare professional.

Algae-based supplements: a vegan-friendly source of B12

For those who do not consume fortified foods or fermented products, algae-based supplements can be an excellent source of B12. Although various types of algae may contain B12, chlorella, and spirulina are the most commonly used for supplementation.

Chlorella is a single-celled green freshwater alga that is often touted for its high protein content and antioxidant properties. Chlorella supplements may contain small amounts of naturally occurring B12, but they are usually fortified with synthetic B12 to provide sufficient amounts.

On the other hand, Spirulina is a blue-green freshwater or saltwater algae that naturally contains small amounts of active B12 and pseudovitamin-B12 – substances similar to but not quite the same as true vitamin B12. Spirulina supplements may therefore be a viable option for some vegans who require less B12 supplementation.

Choosing the right supplement

what vegan food has b12It’s important to note that not all algae-based supplements are created equal regarding their quality and ability to provide adequate levels of vitamin B12. Look for brands that use third-party testing to ensure their products contain accurate doses of vitamins and minerals, including B12. It’s also essential to talk to your doctor or healthcare provider before starting any new supplement regimen.

Some people may find that they do not absorb synthetic forms of B-12 as readily as natural forms found in animal products or fermented foods containing active vitamin B-12. In such cases, they might benefit from injections or sublingual (under-the-tongue) tablets containing methylcobalamin – a form of vitamin B-1 effectively absorbed by many people.

You Should Now Know What Vegan Food Has B12! Vegan sources abound!

While it’s true that many people believe vegans cannot obtain enough vitamin B-12 from their diet, there are actually many vegan-friendly sources of this important nutrient. Vegans can meet their B12 requirements by consuming fortified plant-based foods, fermented foods, or algae-based supplements.

However, it’s essential to do your research and choose high-quality products that provide adequate doses of vitamin B-12. By making informed choices about your diet and supplementation regimen, you can ensure you get all the nutrients your body needs to thrive on a vegan lifestyle.
