Vitamin B12 is an essential nutrient that helps the body produce healthy red blood cells and maintain the nervous system. A deficiency can develop gradually, and symptoms may sometimes be mistaken for ordinary tiredness.
1. Persistent tiredness: Vitamin B12 deficiency can cause anaemia, leaving you feeling weak and exhausted.
2. Tingling in the hands and feet: Low B12 can affect nerves, causing pins and needles or numbness.
3. Memory difficulties: Some people experience problems with concentration, memory or mental clarity.
4. A sore or smooth tongue: Vitamin B12 deficiency can cause inflammation of the tongue and mouth discomfort.
5. Pale or yellowish skin: Anaemia may cause paleness, while certain changes in red blood cells can contribute to a yellowish appearance.
6. Balance problems: Nerve damage may affect coordination and make walking more difficult.
7. Mood changes: Some people experience low mood, irritability or other psychological symptoms.
Where can you get vitamin B12? Good sources include fish, meat, eggs, milk and other dairy products. Some fortified foods also contain B12. People following strict vegan diets may need fortified foods or a suitable supplement.
Important advice: Do not start taking high-dose supplements simply because you feel tired. A blood test can help identify whether you have a deficiency. Untreated B12 deficiency can sometimes cause lasting nerve damage.
Final thoughts: Vitamin B12 is important for blood and nerve health. If you experience persistent fatigue, numbness or balance problems, seek medical assessment instead of assuming the cause is ordinary stress.
