Vitamin B12 is a so-called essential vitamin. This means that the body cannot produce it or cannot produce it to a sufficient degree itself. Vitamin B12 can be produced in very small amounts by bacteria in the small intestine. Without a regular supply of vitamin B12 via food, the health of the human organism can be adversely affected.

Please note: in case of a vitamine B12 injection, you should wait minimum 4 weeks before testing. Orally administered vitamine b12, however, doesn't influence the test result.
