Vitamin B12 Injection explained
Vitamin B12 is needed to make healthy red blood cells and to keep nerves working. Low B12 can cause tiredness, numbness, a sore tongue or anaemia. It is more common in vegans, older adults, people on metformin or acid-reducing medicine, and those who have had stomach surgery.
How Vitamin B12 Injection works
B12 is given as an injection into a muscle, usually as cyanocobalamin or hydroxocobalamin. An injection bypasses the gut, which helps people who cannot absorb B12 from food. In people with normal levels, extra B12 is simply passed in urine and is unlikely to boost energy.
