According to a 2024 study, the optimal frequency for vitamin injections varies widely depending on individual needs and health goals. Deciding how often should you inject vitamins requires personalized medical guidance, but general protocols exist for common deficiencies like B12 and D, as well as for general wellness and immune support.

The effects of a single vitamin B12 injection can vary dramatically, lasting anywhere from one week to several months, depending heavily on individual factors like metabolism and the severity of an underlying deficiency. Understanding this variability is key for anyone asking how long do vitamin B injections last, especially as it influences the required treatment schedule and long-term benefits.
