Vitamin B12, also known as cobalamin, is an essential nutrient that plays a vital role in keeping the body and mind healthy. Unlike many vitamins, B12 is not produced by the body and must be obtained through diet or supplementation. Whilst this vitamin is only required in relatively small amounts, its impact on overall health is enormous.
Why Does Vitamin B12 Matter?
Vitamin B12 supports some of the body’s most critical functions, from energy production to brain health. A deficiency can cause fatigue, memory problems, mood imbalances, and even long-term nerve damage if left untreated. Ensuring adequate levels of B12 is especially important for people who follow plant-based diets, older adults, those with digestive conditions that affect nutrient absorption and, in my opinion, anyone who may have a toxic load (think smoking, vaping, alcohol).
Key Benefits of Vitamin B12
1. Boosts Energy and Reduces FatigueB12 is crucial for converting food into energy. It helps the body produce red blood cells, which carry oxygen throughout the body. Without enough B12, red blood cell production drops, often leading to fatigue, weakness, or anaemia.
2. Supports Brain and Nervous System Health This vitamin protects nerve cells and is vital for producing neurotransmitters that influence mood and cognitive function. Studies suggest that B12 may help reduce the risk of memory loss, support concentration, and protect against age-related cognitive decline.
3. Enhances Mood and Mental Wellbeing B12 contributes to the production of serotonin, the “feel-good” brain chemical. Low levels have been linked to mood disorders like depression and anxiety. Adequate B12 can help support emotional balance and resilience.
4. Promotes Healthy Skin, Hair, and Nails By aiding in cell reproduction, B12 helps maintain the health of rapidly dividing cells, including those that form your skin, hair, and nails. Deficiency may result in skin irritation, brittle nails, or hair thinning.
5. Supports Heart Health Vitamin B12 helps regulate homocysteine levels, an amino acid that, when elevated, can increase the risk of heart disease. Keeping homocysteine in check supports cardiovascular health.
6. Vital for Pregnant Women and Foetal Development During pregnancy, B12 is essential for foetal brain and nervous system development. Deficiency in expectant mothers can increase the risk of birth defects and complications. Check your pregnancy supplements have B12 as part of the formula.
Natural Sources of Vitamin B12
Vitamin B12 is primarily found in animal-based foods such as:
Meat (beef, lamb, poultry)
Fish and shellfish (salmon, tuna, clams)
Eggs
Dairy products (milk, yoghurt, cheese)
If you are following a vegan or vegetarian lifestyle, fortified foods such as plant-based milks, breakfast cereals and nutritional yeast are valuable options. Supplements are also widely available in tablets, sprays or injections if additional support is needed.
Who May Need Extra B12?Vegans and vegetarians (as dietary sources are limited)
Older adults (as reduced stomach acid can impair absorption)
People with digestive conditions (such as Crohn’s or coeliac disease)
Individuals on certain prescribed medicines.
Individuals with a poor diet or negative lifestyle factors (for example, smoking / drinking / vaping / eating junk food / takes outs etc)
B12 is essential for many functions in our body. If you are unsure if you need supplementation, please do get in touch for an appointment. If you would like to purchase B12, Biocare has excellent quality supplements. Please find out more about their range, and also how to receive a discount when you order here.
