Maintain Your Vitamin B12 Intake During Veganuary

As we step into the new year, a growing number of individuals embark on ‘Veganuary’, a global movement inspiring people to adopt a vegan lifestyle for the first month of the year. Starting on this plant-based adventure can present unique nutritional challenges, though, particularly when it comes to maintaining adequate vitamin B12 intake. 


B12, a vital nutrient predominantly found in animal products, plays an essential role in nerve function, red blood cell production, and DNA synthesis. Its deficiency can lead to significant health issues, including anaemia, nerve damage, and cognitive disturbances. 


For those embracing Veganuary, ensuring sufficient B12 intake becomes crucial as you navigate through Veganuary and beyond.

The Role of Vitamin B12

In the Body


Vitamin B12 is a vital water-soluble vitamin essential for several key functions in the body. Unique among B vitamins for containing the metal ion cobalt, B12 plays a crucial role in the formation of red blood cells, aiding in DNA creation and preventing megaloblastic anaemia, which causes fatigue and weakness due to insufficient oxygen transport.


Its significance extends to the nervous system, where it helps in the synthesis of myelin, the protective covering of nerve fibres. This is crucial for the efficient transmission of nerve impulses, and a lack of B12 can lead to neurological issues like numbness and impaired balance.


Additionally, B12 is involved in energy metabolism, converting carbohydrates into glucose, which the body uses for energy. This process is essential for maintaining consistent energy levels. B12 also works with other B vitamins to regulate mood, heart health, and immune function.

In the Brain


Cognitively, B12 is linked to brain health, with adequate levels potentially reducing the risk of cognitive decline in older adults. This is particularly important as the body’s ability to absorb B12 diminishes with age.

Recognising B12 Deficiency


Vitamin B12 deficiency can manifest in various ways, and recognising the signs is key to addressing the issue promptly.


Signs and Symptoms


  • Fatigue and Weakness: One of the earliest signs of B12 deficiency is an unusual level of fatigue and general weakness.

  • Neurological Changes: This may include tingling and numbness in the hands and feet, balance problems, and altered reflexes.

  • Mood Disturbances: Deficiency can lead to mood swings, depression, and cognitive changes like memory loss.

  • Physical Symptoms: These can encompass a pale complexion, a sore and red tongue, and mouth ulcers.

People at Risk


  • Vegetarians and Vegans: Since B12 is primarily found in animal products, those following plant-based diets are at a higher risk.

  • Elderly Individuals: Age-related changes in stomach acidity can reduce B12 absorption.

  • People with Gastrointestinal Issues: Conditions like Crohn's disease or coeliac disease can hinder the absorption of B12.

  • Individuals on Certain Medications: Long-term use of acid reflux drugs and metformin for diabetes can affect B12 absorption.


Understanding these signs, symptoms, and risk factors is crucial for early detection and treatment of Vitamin B12 deficiency, particularly for at-risk populations, to prevent long-term health complications.

Sources of Vitamin B12


Vitamin B12 is an essential nutrient found in a variety of foods, and with the right choices, it can be easily included in any diet, including plant-based ones.

Plant-Based/Vegan Sources


For those following a vegan lifestyle, several fortified foods and supplements can help maintain optimal B12 levels:


  • Plant Milk: Soy, almond, and rice milk often include added B12.

  • Fortified Breakfast Cereals: Many cereals are enriched with B12, offering a quick and easy source.

  • Nutritional Yeast: Popular in vegan cooking for its cheesy flavour, it's also a great source of B12.

  • B12 Supplements: Vegan-friendly B12 supplements ensure you get your daily dose.

  • Fortified Meat Substitutes: Many vegan meat alternatives are fortified with essential nutrients like B12.


Incorporating these fortified foods and supplements into a vegan diet, especially for those partaking in Veganuary, is a proactive way to ensure adequate B12 intake. Regular monitoring with services like One Day Tests can also support maintaining healthy B12 levels.

Animal-Based Sources


  • Meat and Poultry: Beef, liver, and chicken are excellent sources of B12.

  • Seafood: Fish like salmon, tuna, and sardines are rich in B12.

  • Dairy Products: Milk, cheese, and yoghurt contain significant levels of B12.

  • Eggs: Particularly the yolks, are a good source of B12.
