What Is Vitamin B12?
We’ve talked briefly about Vitamin B12 in another post, but Vitamin B12 deserves a separate chapter due to its importance.
Vitamin B12 is a water-soluble vitamin that is found in animal products like meat, fish, dairy, and eggs.
It’s not produced by plants, which means that vegans and vegetarians are at a higher risk for B12 deficiency.
The body needs vitamin B12 to form red blood cells, DNA synthesis, and to keep the nervous system functioning correctly.

Why Is Vitamin B12 So Important?
Vitamin B12 is essential for the body to perform various functions.
Here are some reasons why vitamin B12 is so important:
- Red Blood Cell Formation:
Vitamin B12 plays a crucial role in the formation of red blood cells, which carry oxygen throughout the body.
Without enough B12, the body cannot produce enough red blood cells, leading to anaemia.
Anaemia can cause symptoms such as fatigue, weakness, and shortness of breath.
- DNA Synthesis:
Vitamin B12 is necessary for the synthesis of DNA, the genetic material found in cells.
Without enough B12, the body cannot produce enough healthy cells, leading to abnormal cell division, which can cause various health problems.
- Neurological Function:
Vitamin B12 is essential for the development and maintenance of the nervous system.
It helps produce myelin, a protective sheath around nerve fibres that helps conduct electrical signals.
Without enough B12, nerve cells can become damaged, leading to neurological problems such as tingling and numbness in the hands and feet, difficulty walking, and even dementia-like symptoms.
- Energy Production:
Vitamin B12 plays a vital role in the metabolism of protein and fat, making it necessary for energy production.
It helps convert food into glucose, the body’s primary source of energy.
Without enough B12, the body cannot produce enough energy, leading to fatigue and weakness.
- Brain Function:
Research has shown that vitamin B12 is essential for brain function, including memory and mood.
Deficiency in B12 has been linked to cognitive impairment, depression, and other mental health problems.
Who Are Most At Risk For Deficiency?
Some people are more at risk for B12 deficiency than others. This includes:
- Vegans and vegetarians who do not consume enough B12-rich foods.
- Older adults, as the body’s ability to absorb B12 decreases with age.
- People who have had gastrointestinal surgery, such as weight loss surgery, as the procedure can affect the body’s ability to absorb B12.
- People who have gastrointestinal disorders, such as Crohn’s disease or celiac disease, which can affect the body’s ability to absorb B12.
Symptoms Of B12 Deficiency
The symptoms of B12 deficiency can vary depending on the severity of the deficiency.
Some common symptoms include fatigue, weakness, constipation, loss of appetite, and weight loss.
In severe cases, a deficiency can cause nerve damage, leading to tingling and numbness in the hands and feet, difficulty walking, infertility, hypothyroidism, depression and even dementia-like symptoms.
Foods Rich In Vitamin B12
B12 is primarily found in animal products, including meat, fish, poultry, dairy, and eggs.
Some plant-based foods are fortified with B12, such as breakfast cereals and plant-based milk.
However, these foods may not provide enough B12 to meet the body’s needs, besides being full of sugars, which does more bad than good.
Vegans and vegetarians must consider taking a B12 supplement to ensure they are getting enough of this essential nutrient and to avoid suffering the consequences of its deficiency.
Final Thoughts
In conclusion, vitamin B12 is an essential nutrient that plays a crucial role in the body’s functioning.
It’s important to consume enough B12-rich foods or take a supplement if at risk for deficiency.
By doing so, you can maintain healthy red blood cell formation, support energy production, and ensure proper neurological function.

FAQs
Can B12 deficiency affect fertility and reproductive health?
Yes, B12 deficiency can potentially impact fertility and reproductive health. Studies have shown that low levels of B12 can lead to an increased risk of infertility and complications during pregnancy, such as neural tube defects and low birth weight. It is recommended for individuals planning to conceive or during pregnancy to ensure adequate B12 intake.
Can B12 deficiency be reversed through diet alone?
In mild cases of B12 deficiency, increasing intake of B12-rich foods or consuming fortified products may be sufficient to correct the deficiency. However, in severe cases or when absorption issues are present, dietary changes alone may not be enough. B12 supplements or injections may be required to restore optimal B12 levels.
Are there any side effects or risks associated with B12 supplementation?
B12 supplementation is generally considered safe and well-tolerated. However, in some cases, high doses of B12 supplements may cause certain side effects, such as diarrhea, itching, or a rash. It is always advisable to consult with a healthcare professional before starting any supplementation regimen.
Are there any natural sources of B12 for vegans and vegetarians?
Vegan and vegetarian diets lack natural food sources of B12, as it is primarily found in animal products. However, there are some plant-based foods that are fortified with B12, such as certain breakfast cereals, plant-based milk, and nutritional yeast. It is important for vegans and vegetarians to carefully plan their diet and consider taking B12 supplements to ensure adequate intake.
Can excessive alcohol consumption contribute to B12 deficiency?
Yes, excessive alcohol consumption can increase the risk of B12 deficiency. Alcohol interferes with the absorption and storage of B12 in the body. Individuals who consume alcohol excessively should be aware of this risk and consider monitoring their B12 levels or taking supplements if necessary.
Can B12 deficiency be diagnosed through symptoms alone?
While certain symptoms can indicate the possibility of B12 deficiency, a definitive diagnosis requires a blood test to measure B12 levels. Symptoms alone may not provide a complete picture, as they can overlap with other health conditions. If you suspect you have B12 deficiency, it is important to consult with a healthcare professional for proper testing and diagnosis.
