Vitamin B-12 shots are injections that treat a vitamin B-12 deficiency.

Vitamin B-12 is an essential water-soluble vitamin that plays an important role in many functions in the body, including:

  • Energy production

  • Nerve cell health

  • Red blood cell formation

  • Neurological function

Vitamin B-12 shots are injections containing high levels of cyanocobalamin.

Anyone who is displaying any of the signs and symptoms of a B-12 deficiency or pernicious anaemia should consult their doctor immediately.

Some common signs and symptoms include:

  • Decreased cognitive function, such as issues with memory or understanding

  • Fatigue

  • Lethargy

  • Constipation

  • Feeling faint

  • Depression or irritability

  • Headache

  • Difficulty maintaining balance

  • Sore, swollen tongue, which may be pale yellow or very red

  • Heart palpitations

  • Mouth ulcers

  • Paresthesia (pins and needles)

  • Vision changes


Vitamin B-12 is crucial to the normal function of the brain and the nervous system. It is also involved in the formation of red blood cells and helps to create and regulate DNA.

The metabolism of every cell in the body depends on vitamin B-12, as it plays a part in the synthesis of fatty acids and energy production. Vitamin B-12 enables the release of energy by helping the human body absorb folic acid.

The human body produces millions of red blood cells every minute. These cells cannot multiply properly without vitamin B-12. The production of red blood cells reduces if vitamin B-12 levels are too low. Amenia can occur if the red blood cell count drops.
