Britons are being urged not to ignore common everyday symptoms that could signal a serious vitamin deficiency affecting millions of people across the UK.
The Silent Warning Signs
According to medical expert Suzy Glaskie, founder of Peppermint Wellness, symptoms many of us dismiss as normal tiredness could actually indicate a dangerous vitamin B12 deficiency. "We're seeing people pushing through fatigue, brain fog, and headaches without realising these could be warning signs from their body," Glaskie explained.
Key Symptoms to Watch For
The most concerning indicators include:
- Persistent fatigue that doesn't improve with rest
- Brain fog and difficulty concentrating
- Unexplained headaches and migraines
- Muscle weakness and general lethargy
- Mood changes including depression and irritability
Why B12 Matters
Vitamin B12 plays a crucial role in maintaining healthy nerve cells and producing DNA. A deficiency can lead to serious neurological problems and blood disorders if left untreated. "The body can't make B12 on its own," Glaskie emphasised. "We must get it from our diet or supplements."
Who's Most at Risk?
Certain groups are particularly vulnerable to B12 deficiency:
- Vegans and vegetarians - since B12 is primarily found in animal products
- Older adults - due to reduced stomach acid affecting absorption
- People with digestive disorders like Crohn's disease or coeliac disease
- Those on certain medications including metformin and proton pump inhibitors
Taking Action
Glaskie recommends consulting your GP if you experience persistent symptoms. "Don't self-diagnose," she warned. "Blood tests are essential for proper diagnosis, and treatment might include dietary changes, supplements, or in severe cases, injections."
With NHS services under pressure, prevention through a balanced diet rich in B12 sources like meat, fish, eggs and dairy remains the best approach for most people.
