Fed Up of Feeling Tired All the Time? Could Vitamin B12 Be a Factor?
07/10/2025How many of us operate at a level of “general tiredness”: struggling with low energy, waking up exhausted, finding it hard to focus, becoming forgetful or short-tempered? We might blame it on life’s pressures, or the shortening autumn days. Habits like getting enough sleep, taking time for yourself, and eating a balanced, nutritious diet help maintain a healthy lifestyle, but can be hard when you’re constantly juggling, or battling tiredness. One possible cause of tiredness in some people can be vitamin B12 deficiency.
What is Vitamin B12?
This essential vitamin plays a key role in keeping your body and mind healthy, supporting red blood cell production, energy metabolism, neurological and brain function. When levels drop, the effects can be life-limiting, including persistent tiredness and fatigue, muscle weakness, shortness of breath or dizziness, poor memory or difficulty concentrating, low mood or irritability.
Our bodies do not produce vitamin B12, getting it from foods like meat, fish, milk and eggs. Modern life can make it hard for anyone to get enough vitamin B12 from their diet, not just those on a plant-based diet. The ability to absorb through diet alone can also decline with age, post gastric surgery, or medical and digestive conditions like pernicious anaemia, Crohn’s or coeliac disease.
Vitamin B12 Injections: When Might They Be Suitable?
Vitamin B12 injections may be recommended for people with confirmed deficiency or when supplementation by injection is clinically appropriate. The time taken to notice improvement varies depending on the individual, the cause of deficiency and the treatment approach.
Unfortunately, in certain circumstances vitamin B12 injections are no longer available on the NHS from your GP. While oral tablets and medicines are readily available, and can be suitable for general B12 maintenance, vitamin B12 injections deliver the vitamin directly into the body and may be appropriate for some people depending on their individual circumstances. That’s why our trained team at Brock Street Pharmacy offer a convenient and professional vitamin B12 injection service right here in Lancaster.
