According to research, the biological half-life of vitamin B12 in the blood is approximately six days, but the length of time its benefits are felt varies greatly between individuals based on their health status. Knowing how long does a vitamin B shot stay in your system depends on multiple factors, including your body's initial deficiency and how it processes the vitamin.

Most people feel a noticeable energy boost within 24 to 72 hours of receiving a B12 injection, with the overall duration of benefits lasting anywhere from a few days to a few weeks, or even months for some individuals. The longevity of a vitamin B shot depends on many factors, including the type of vitamin, the individual's metabolism, and the severity of their deficiency.
