Vitamin B12 is a vital nutrient, with the responsibility of maintaining nerve cell health, brain health, and meeting the needs of red blood cell synthesis as well as DNA. B12 cannot be synthesized within the body like other vitamins and must be supplemented from outside. Low B12 will cause weakness, fatigue, mood swing, and even irreversible neurological damage if not remedied.
This essential nutrient that naturally found in meat, eggs, and dairy products. Thus, vegans are at higher risk of B12 deficiency. In fact, according to one study conducted by Nutrients (2014), 86% of vegans can develop B12 deficiency if they do not take supplements or fortified foods. The purpose of this blog is to help vegans make smart choices by taking into account the best vitamin B12 supplements for vegans to create energy, mental well-being, and overall well-being.
Why Vitamin B12 is essential for Vegans?
Vitamin B12, or cobalamin, plays an active role in many body functions. It assists the body with the production of red blood cells, maintaining healthy nerve cells, and assisting in the formation of red blood cells for DNA. One of its functions is helping to break down food into glucose that can be utilized as energy. In a state lacking B12, it is unable to produce healthy red blood cells, and the outcome is poor oxygenation and fatigue.
The nervous system also depends heavily on B12 to function properly. It has the duty of providing the healthy nerve covering (myelin). Without it, nerve damage symptoms like numbness and tingling in fingers and toes, impaired balance, memory loss, and even mood swings like depression or irritability arise.
B12 deficiency is particularly prevalent in vegans since the vitamin occurs naturally in animal food—meat, fish, eggs, and milk. B12 is not synthesized or stored in plants, and it is nearly impossible to obtain a sufficient amount from plant foods other than fortified foods or supplements. There are certain foods that are not animal products but contain artificial B12, but perhaps these foods might not be providing us with sufficient amounts of the vitamin daily, particularly if they are eaten less often.
The long-term effects of B12 deficiency are catastrophic and irreversible. In the most severe instances, neurologic damage is irreversible. Because of this alone, vegans will have to take proactive steps to monitor and ensure healthy levels of B12—making supplementation not only valuable, but crucial.
Signs & Symptoms of Vegan B12 Deficiency
Deficiency of Vitamin B12 will become evident after months and is hard to diagnose in the early stages, but its impact is devastating. The features are tenuous fatigue, weakness, pale or yellow tinge on the skin, and shortness of breath on minimal exercise. The patients typically also have brain fog, memory loss, confusion, and mood change such as irritability or depression.
As the deficiency becomes more advanced, there may be complications of the nervous system including numbness or tingling in hands and feet, weakness, and loss of coordination or balance. The worst of all the complications is megaloblastic anemia, where the body produces normally large, healthy red blood cells. Permanent damage to the nervous system, including impaired mental function, will result if the chronic B12 deficiency is not corrected.
Vegans with these symptoms can have a B12 blood test and CBC to assess if red blood cell health is normal. Go to a doctor; otherwise, symptoms will be ongoing or get worse. B12 supplements and early diagnosis can cure most symptoms and avert long-term sickness.
How Much B12 Do Vegans Need?
Dietary Recommended Allowance of vitamin B12 in adults is 2.4 micrograms (mcg) daily. Such a small quantity is sufficient to address body requirements—if adequately absorbed. Still, the human body can only absorb half of the B12 from food or supplement, particularly if large quantities are used.
This is because health practitioners and facilities will recommend additional dosages of supplements, especially in vegetarians. The normal recommendation is taking 25–100 mcg of B12 supplement daily or 500–2,500 mcg weekly. These dosages will guarantee that enough B12 will be taken into the body regardless of the low capacity of the body to absorb the vitamin by passive absorption.
For example, with a high-dose B12 supplement, only 1–2% of it is passively absorbed, and so even on a 1,000 mcg supplement, maybe only 10–20 mcg would actually be absorbed into the bloodstream—barely enough to cover daily needs.
With such absorption factors being present, high dose B12 supplements work and are safe to keep levels in optimal, particularly for vegans who are not accessing B12 from food. Maintenance through supplementation prevents deficiency and ensures general energy, mood, and nerve function.
Forms of Vegan B12 Supplements
There are different forms of vegan B12 supplements, with their pros and cons. Cyanocobalamin and methylcobalamin are the most popular forms of B12 supplements. Cyanocobalamin is the stable, affordable, and readily available synthetic form. It is the one that has been well studied and is useful in preventing and treating B12 deficiency. It is metabolized by the body into active forms of B12 when taken in.
Methylcobalamin is an endogenous, bioactive B12 which some people, particularly those with metabolic or genetic problems, absorb more effectively. It will not be stable and will cost more than cyanocobalamin.
Some of the most common available supplements are:
- Tablets & Capsules: Most frequently used and cheapest formulation. Simple to administer but perhaps not ideal for the patient with gut impairment of absorption.
- Sublingual Tablets: B12 dissolves under the tongue where it will be absorbed straight into the body by way of the blood. Great for those who don’t absorb nutrients well in the gut.
- B12 Gummies: Tasty and easy to swallow, perfect for those who hate swallowing pills. But maybe contains added sugar or artificial flavor.
- B12 Sprays: Applied to the mouth and absorbed through mucous membranes. Great convenience option and best suited for individuals who would rather not have to swallow capsules.
- B12 Injections: Usually given in doctor’s offices for individuals with acute deficiency or compromised absorption. Not required for the vast majority of vegans who supplement on a regular basis.
Everything about how to appropriately formulate based on taste preference, health requirement, and lifestyle. Daily intake of any good vegan B12 supplement will be sufficient to sustain the ideal levels.

Vitamin B12-Rich Vegan Foods (Fortified)
Since there is no naturally occurring B12 found in plant foods, most vegan food products carry synthetic B12 added to them to meet nutritional needs. Some of the leading best-selling B12-fortified vegan food products include:
- Nutritional yeast: It is a favorite among vegan foods, has a nutty, cheesy flavor, and is enriched most commonly with B12—1 tablespoon delivers 100% daily value.
- Plant milks: Almond milk, soy milk, oat milk, and rice milk brands have supplemented with B12 for most of them. Check the labels.
- Breakfast cereals: Certain breakfast cereals that are made of whole grains or multigrains are supplemented with B12—particularly those which are marked vegan or health foods.
- Soy products: Certain soy meat substitutes and certain tofu have supplemented B12 to be as healthy as foods from animals.
Although these foods contribute to B12 intake, they are perhaps not consumed regularly or in sufficient amounts to supply day-to-day needs, particularly if they are not frequently consumed. Levels of fortification also vary greatly by firm and batch.
Supplementation is thus still necessary for everyone who is a vegan. It provides a measurable, consistent means to avoid deficiency and maintain long-term health—namely in the maintenance of energy, mood, and nerve function.
