Feeling more tired than usual isn’t always a normal part of getting older. If you’re experiencing ongoing fatigue, tingling in your hands or feet, difficulty with balance, or problems with memory and concentration, it may be worth asking your GP about your vitamin B12 levels.

Vitamin B12 deficiency is relatively common in older adults and can develop gradually, making the symptoms easy to overlook.

Vitamin B12 plays an important role in keeping your nerves and blood cells healthy. As we age, our bodies can become less efficient at absorbing it from food. Certain medications and digestive conditions may also reduce absorption, even if you’re eating a balanced diet.

Early symptoms can be subtle. You might feel unusually tired, become short of breath during activities that were once easy, or notice pins and needles in your hands or feet. Some people also experience problems with balance, mood changes, or difficulty remembering things. Because these symptoms can have many different causes, it’s important not to diagnose yourself.

Good dietary sources of vitamin B12 include meat, fish, eggs, milk, cheese, and yoghurt. Some breakfast cereals and plant-based milks are fortified with B12, which can be helpful for people who eat little or no animal products. However, if your body isn’t absorbing the vitamin properly, diet alone may not be enough.

A simple blood test can often determine whether your B12 level is low. If a deficiency is confirmed, treatment may involve dietary changes, supplements, or injections, depending on the cause and severity. Many people notice an improvement in their symptoms once their levels are restored.

If you’ve developed numbness, weakness, or balance problems, don’t wait for your next routine check-up. Early assessment is important because some effects of long-term vitamin B12 deficiency can become permanent if left untreated.

Recognising the signs of vitamin B12 deficiency and seeking medical advice early may help you stay active, independent, and feeling your best.
