Vitamin B12 Injections

Vitamin B12 is a water-soluble vitamin. B12 plays a vital role in brain function and the production of DNA and red blood cells. Lack of B12 can damage the nervous system and can cause cognitive issues like confusion and poor memory.

B12 deficiency is common, especially in people who follow a vegetarian or vegan diet. It is thought that up to 90% of people following these diets have a B12 deficiency due to lack of animal products, as B12 is mainly found in eggs, dairy products, fish, meat and poultry. The absorption of B12 depends on a protein produced in the stomach which decreases with age, therefore even meat eaters can be deficient in this vitamin. Vitamin B12 can increase energy and help you feel less lethargic.

The injection is given in the arm, intramuscularly.
