You should feel the effects in about 20 minutes of the injection. I never felt much from B12 shots either, but now I do take multi-B tablets about 3 hours into my shift at work. I find it helps me, makes a noticable difference in how I feel the rest of my day.

It is difficult to determine exactly how long it will take for the effects of B12 to kick in as it can vary from person to person. Some individuals may feel a difference after the first injection, while others may take longer to notice any changes. It is also important to note that B12 injections are typically used to treat deficiencies and not necessarily for immediate effects. Therefore, it may take some time for the body to absorb and utilize the B12 properly. If you have concerns about the effectiveness of your B12 injections, it is best to consult with your healthcare provider for personalized advice.
