For many people with a severe B12 deficiency, injections can begin to improve energy levels and reduce fatigue within 24 to 72 hours. Knowing how long does it take to recover from B12 injections is crucial for managing expectations and adhering to your treatment plan.

Mild side effects from a vitamin B12 shot, such as injection site soreness, typically resolve within a few hours to a couple of days. Understanding the typical duration of these reactions can help you distinguish between normal, temporary discomfort and something that requires medical attention, especially within the context of a balanced nutrition diet.
