An NHS GP has stepped forward to highlight two crucial vitamins that millions of Britons might be lacking - deficiencies that could explain why you're constantly tired, feeling low, or catching every bug that goes around.
Dr. Sunni Patel, a practising NHS GP with over 12 years' experience, explains that while vitamin deficiencies can affect anyone, certain groups are particularly vulnerable. "Many people come to my clinic complaining of persistent tiredness, low mood, or frequent illnesses without understanding the root cause," he reveals.
The Silent Epidemic: Vitamin D Deficiency
Despite Britain's healthcare advances, vitamin D deficiency remains widespread, particularly during the darker months from October to early March. "Vitamin D isn't just about bone health," Dr. Patel emphasizes. "It plays a vital role in immune function, muscle strength, and even mood regulation."
The symptoms of insufficient vitamin D levels can be subtle but impactful:
- Persistent fatigue and low energy
- Frequent colds and infections
- Low mood or feelings of depression
- Bone pain and muscle weakness
- Hair loss in some cases
Natural sources include sunlight exposure, oily fish, egg yolks, and fortified foods. However, during winter months, Public Health England recommends that all adults and children over one consider taking a daily 10 microgram supplement.
The Energy Vitamin: B12's Crucial Role
Vitamin B12 deficiency represents another common but often overlooked health issue. "B12 is essential for nerve function, red blood cell formation, and DNA synthesis," Dr. Patel explains. "When levels drop, the consequences can be significant."
Warning signs of B12 deficiency include:
- Extreme tiredness and lethargy
- Brain fog and memory problems
- Pins and needles sensations
- Mouth ulcers and sore tongue
- Psychological changes including depression
Those most at risk include vegans and vegetarians, older adults, people with digestive conditions like Crohn's disease, and those taking certain medications long-term.
Simple Steps to Better Health
Dr. Patel recommends consulting your GP if you suspect a deficiency, as blood tests can provide clarity. For general maintenance, he suggests:
- Consider a quality vitamin D supplement, especially from October to March
- Include B12-rich foods like meat, fish, eggs and dairy in your diet
- Vegans should consider fortified foods or supplements
- Get sensible sun exposure during warmer months
- Maintain a balanced, varied diet year-round
"These simple measures could make a dramatic difference to how you feel day-to-day," Dr. Patel concludes. "Often, the solution to persistent health niggles lies in addressing basic nutritional needs that modern lifestyles frequently overlook."
