Vitamin B12 deficiency is widespread. The reasons vary, but often this has something to do with the way we live and what we eat. Our bodies are constantly exposed to pollutants and pesticides, as well as the genetic modifications added to the animal foods we consume. Since the compound is only present in animal-based foods, the task of having a high enough supply of vitamin B12 is especially difficult for vegans and vegetarians.
Whenever people find it difficult to maintain adequate vitamin B12 levels, either because they have an absorption problem or follow a vegan or vegetarian diet, B12 supplements often come to their aid.

Vitamin B-12 injections are considered to be safe and come with no major adverse effects. The effects of a vitamin B12 shot usually last between 48 and 72 hours after the injection, but since each body is different, the duration may vary.
