Vitamin B12 is a vital nutrient that plays a crucial role in maintaining a healthy body. However, for vegans and vegetarians, getting enough B12 from their diet alone can be a challenge, as this essential vitamin is primarily found in animal products.
That’s where vegan B12 supplements come in. But how is vegan B12 made? There are two main methods used to produce vegan B12 – fermentation and synthesis.
In this article, we will explore the manufacturing process behind vegan B12 in detail. We will also discuss the need for B12 supplementation for vegans and vegetarians, as well as the various vegan-friendly sources of B12 in the diet and in supplement form.
So, how is vegan B12 made? Let’s find out.
The Need for Vegan B12
Vitamin B12 is essential for healthy nerve and blood cells, and for DNA production. It is primarily found in animal products, which makes it challenging for vegans and vegetarians to get enough of this nutrient in their diet.
It is vital for vegans to obtain adequate levels of B12 as deficiency can lead to health problems such as fatigue, anaemia, and nerve damage. Fortunately, there are vegan-friendly sources of B12 in fortified foods and supplements.
The recommended daily intake of B12 for adults is around 2.4 micrograms, and this may increase for pregnant and breastfeeding women. Vegan-friendly sources of B12 include fortified plant-based milks, breakfast cereals, nutritional yeast, and supplements.
It is essential to choose vegan-friendly sources of B12, which are certified by vegan authorities, to ensure that no animal products were used in the production process.
Fermentation Method
The fermentation method is one of the primary ways of producing vegan B12. This method involves the use of bacteria to produce the vitamin in a nutrient-rich medium. There are several sources of bacteria used in fermentation, including soil, water, and plant material.
During the fermentation process, the bacteria are fed a nutrient-rich medium to encourage B12 production. The nutrient mix typically includes a source of glucose, along with other vitamins and minerals. The bacteria then produce B12 as part of their metabolic processes, which is then extracted from the medium and purified for use in supplements and fortified foods.
The fermentation method is generally considered to be one of the most effective ways of producing B12 for vegans, as it results in a pure and bioavailable form of the vitamin. It is also a natural and eco-friendly process that does not require the use of harsh chemicals or synthetic compounds.
Synthetic Method
The synthetic method is another way to produce vegan B12. Unlike the fermentation method, which uses bacteria to produce B12, the synthetic method involves synthesizing B12 from scratch using various raw materials.
The process begins with the chemical compound called cobalt, which is combined with various other compounds to create cyanide, which is then combined with other compounds to create a precursor to B12 known as cobinamide.
This precursor is then transformed into B12 through a series of chemical reactions that involve the addition of other compounds, including dimethylbenzimidazole and adenosylcobalamin.
The synthetic method is more expensive than the fermentation method, but it offers greater control over the purity and dosage of B12. However, some vegans are wary of synthetic B12 due to concerns about the safety and environmental impact of the raw materials used in the process.
Options for Vegans
Vegans and vegetarians need to supplement their diets with vitamin B12, as it is primarily found in animal products. Fortunately, there are a range of vegan-friendly sources of B12 available, including:
- Vegan B12 supplements: These are a convenient way to ensure you are getting enough B12. Look for supplements that are labelled as vegan-friendly, and that use either the synthetic or fermentation methods to produce B12.
- Fortified foods: Many plant-based milks, breakfast cereals, and meat alternatives are fortified with B12. Check the label to make sure that the fortified food is vegan-friendly, and that it contains an adequate amount of B12.
- Nutritional yeast: This is a popular ingredient in vegan cooking, and is often fortified with B12. Nutritional yeast can be added to dishes for a cheesy, umami flavour, and is a great natural source of B12.
While it is possible to get some B12 from natural sources like seaweed and mushrooms, it is difficult to get enough from these sources alone. Supplementation is generally recommended for vegans and vegetarians to ensure adequate B12 intake.
Benefits of Vegan B12
B12 is an essential nutrient for overall health, and vegans can benefit significantly from ensuring that they get enough of it in their diet. Here are some of the advantages associated with vegan B12:
- Improved energy levels: B12 supports the body’s natural energy production processes, so ensuring adequate intake can help you feel more alert and energised.
- Better cognitive function: B12 helps to maintain healthy nerve cells, which can improve cognitive function and reduce the risk of neurological disorders.
- Stronger immune system: B12 is essential for the production of white blood cells, which play a critical role in fighting off infections and diseases.
Vegans should aim to consume between 250-500 mcg of B12 per week to reap these benefits.
The Role of B12 in the Body
B12 is an essential vitamin that plays a crucial role in many bodily functions. It is necessary for the formation of red blood cells, nerve function, and DNA synthesis. Our bodies do not produce B12 naturally, so we need to obtain it from external sources such as food or supplements.
In addition to its vital functions, B12 is also important for our overall health. A deficiency in B12 can lead to fatigue, weakness, and shortness of breath. It can also cause more serious health problems such as anemia, nerve damage, and even depression.
For vegans and vegetarians, ensuring adequate intake of B12 is especially important. Without adequate levels of this vitamin, they may experience serious health consequences. By incorporating vegan-friendly sources of B12 into their diets, such as fortified foods and supplements, vegans and vegetarians can ensure they receive the necessary levels of this vital nutrient.
Choosing Vegan-Friendly Supplements
When it comes to choosing the best vegan-friendly B12 supplements, there are a few important factors to consider. First, it is important to choose a supplement that contains a form of B12 that is easily absorbed by the body. Methylcobalamin and cyanocobalamin are two popular forms of B12 that are well-absorbed, and are often used in vegan-friendly supplements.
It is also important to read supplement labels carefully to ensure that they are vegan-friendly. Look for supplements that are clearly labelled as “vegan” or “plant-based”, and avoid supplements that contain animal-derived ingredients such as gelatin or lactose.
Another important consideration is the method used to produce the supplements. Look for supplements that are made using vegan-friendly methods, such as fermentation or synthesis. These methods are more sustainable and ethical than animal-based methods, and are often favoured by vegan supplement manufacturers.
Finally, it is important to choose a reputable brand when purchasing B12 supplements. Look for brands that are transparent about their ingredients and manufacturing processes, and that have a good reputation in the vegan community.
Fortified Foods for Vegans
Fortified foods are a convenient way for vegans to ensure they are getting enough B12 in their diet. Many plant-based milks, breakfast cereals, and meat alternatives are fortified with B12, making it easy to incorporate into your daily routine.
When choosing fortified foods, it’s important to read the labels carefully to ensure that they are vegan-friendly. Look for products that are explicitly labelled as vegan or that carry a vegan certification, as some fortified foods may contain animal-derived ingredients.
| Fortified Foods | B12 Content (per serving) |
|---|---|
| Fortified plant-based milk (e.g. soy, almond, coconut) | 0.5 – 3.0 micrograms |
| Fortified breakfast cereal | 0.6 – 6.0 micrograms |
| Meat alternatives (e.g. soy-based “chicken” or “beef”) | 0.5 – 3.0 micrograms |
It’s worth noting that fortified foods may not provide enough B12 on their own, particularly if you have a higher need for B12 (such as during pregnancy or if you are over 50). In these cases, it’s important to supplement your diet with a vegan-friendly B12 supplement.
B12 and Pregnancy
If you’re pregnant or breastfeeding, it’s important to ensure you’re getting enough B12 in your diet. The increased demand for B12 during these times means that deficiency can have serious consequences for both mother and baby.
B12 is crucial for healthy neurological development in infants, and deficiency can lead to developmental delays and cognitive impairment. In mothers, deficiency can cause anaemia, fatigue, and increased risk of infections.
Fortunately, there are plenty of vegan-friendly sources of B12 that are safe to consume during pregnancy and breastfeeding. These include fortified foods and supplements, as well as natural sources such as nutritional yeast and seaweed.
When choosing supplements, it’s important to look for those that are specifically formulated for pregnant and breastfeeding women. These supplements will contain the recommended daily intake of B12, as well as other essential nutrients such as folic acid and iron.
B12 and Aging
As we age, our bodies become less efficient at absorbing and processing nutrients, including B12. This puts older adults at higher risk of B12 deficiency, which can have serious consequences for cognitive function, bone health, and energy levels.
The recommended daily intake of B12 for adults over 50 is 2.4 micrograms, but many older adults struggle to meet this target. This is why it is especially important for older vegans and vegetarians to pay close attention to their B12 intake and consider supplementing their diet.
Vegan-friendly sources of B12 for older adults include supplements and fortified foods, such as plant-based milks and breakfast cereals. It is important to choose B12 supplements that are specifically designed for older adults, as these may contain higher levels of the vitamin and additional nutrients to support bone and cognitive health.
When choosing fortified foods, it is important to read the label carefully to ensure that they are vegan-friendly and suitable for older adults. Some fortified foods may contain additional nutrients that are beneficial for older adults, such as calcium and vitamin D.
