What is Vitamin B12 Shot?
A Vitamin B12 shot is an intramuscular injection containing vitamin B12, an essential nutrient involved in red blood cell formation, normal nerve function and DNA production. Injections are an established treatment for diagnosed B12 deficiency and for people who cannot absorb enough through the digestive system. Tiredness has many possible causes, so an injection should not replace appropriate assessment or blood tests where symptoms are unexplained.
How does Vitamin B12 Shot treatment work?
Vitamin B12 is delivered into a large muscle, where it is absorbed into the bloodstream without relying on the stomach or small intestine. This is useful where dietary intake is inadequate or absorption is impaired. If deficiency is confirmed, the treatment schedule and need for ongoing injections depend on its cause, severity, symptoms and any plan already provided by your GP or specialist.
