Vitamin B12 is a vital part of the B complex family, known for supporting numerous critical functions in the body. Commonly referred to as the “energy vitamin,” Vitamin B12 is essential for sustaining energy levels, promoting red blood cell formation, and maintaining a healthy nervous system. Many people, especially those on vegan or vegetarian diets, are susceptible to Vitamin B12 deficiencies because it’s predominantly found in animal-based foods. Knowing the importance of Vitamin B12 and how to maintain optimal levels is key to a healthier, more energised life.
What Is Vitamin B12 and Why Is It Important?
Vitamin B12, or cobalamin, is a water-soluble vitamin that supports various physiological processes in the body. It plays an essential role in:
- Red Blood Cell Production: Vitamin B12 is vital for red blood cell formation, which helps transport oxygen throughout the body. Low Vitamin B12 levels can lead to a reduced production of healthy red blood cells, causing anaemia. Symptoms of anaemia include fatigue, weakness, and shortness of breath.
- Nervous System Health: Vitamin B12 is necessary for nerve health as it supports the production of myelin, the protective sheath around nerves. A deficiency in Vitamin B12 can lead to neurological symptoms such as tingling or numbness in the hands and feet and, in severe cases, cognitive changes.
- DNA Synthesis: This vitamin is also essential for DNA synthesis, which is the foundation for cell division and growth, making it crucial for overall health and well-being.
Signs of Vitamin B12 Deficiency
Feeling fatigued, experiencing weakness, or having “brain fog” are all common symptoms of Vitamin B12 deficiency. Here are some typical signs to watch for:
- Persistent fatigue and weakness
- Pale or jaundiced skin
- Shortness of breath and dizziness
- Tingling or numbness in the hands and feet
- Mood changes, including depression or irritability
These symptoms can arise when your body isn’t getting enough Vitamin B12 to support energy levels, nerve function, and overall health. If you’re experiencing any of these signs, it might be worth checking your Vitamin B12 levels.
Why Can’t the Body Make Its Own Vitamin B12?
Unlike some vitamins that the body can produce, Vitamin B12 can’t be synthesised by the body. Instead, we rely on food or supplements to meet daily needs. Vitamin B12 is naturally present in animal products like meat, fish, eggs, and dairy, so people following vegan or vegetarian diets may find it challenging to get enough of this nutrient. Pregnant women and older adults also require higher levels of Vitamin B12; during pregnancy, it’s essential for foetal neurological development, while older adults may experience lower absorption of Vitamin B12 due to decreased stomach acid levels.
How to Test for Vitamin B12 Deficiency
Getting a Vitamin B12 test can provide valuable insights into your body’s B12 levels. Many people are choosing at-home Vitamin B12 tests for a convenient, private way to check their health. With a simple test, you can quickly find out if you’re meeting your body’s Vitamin B12 needs. If a deficiency is detected, adjusting your diet or adding a supplement can make a significant difference in your energy levels and overall health.
