Vitamin B12 is a water soluble vitamin, also known as cobalamin. B12 plays a vital role in brain function and the production of DNA and red blood cells. Chemically, vitamin B12 can exist in a number of different forms, but all of them contain the mineral Cobalt.
B12 deficiency is common, especially in people who follow a vegetarian or vegan diet. In fact its thought that up to 90% of people following these diets have a deficiency due to b12 being present naturally, only in animal foods. The absorption of B12 depends on a protein produced in the stomach and decreased with age, therefore even meat eaters can be deficient in this vitamin.
Vitamin B12 shots are extremely common either being given by the NHS or with many people now turning to private clinics to see if this shot can ease their symptoms. The injections I administer are all prescribed in the UK as hydroxocobalamin. The injection is given in the arm, intramuscularly. You may be asking why? Why are people opting for this injection away from the NHS?
The answer is simple, it can take multiple visits and begging to get this shot on the NHS, and you wont get it unless you levels are extremely low. If you aren't deficient you will likely not feel any benefit from the shot, however the vitamin is water soluble so any excess B12 is secreted through our waste system causing no harm.
The list of the potential benefits of healthy B12 levels are immense. These include:
