how often can you have vitamin b12 injections How Can Vitamin B12 Shots

(what science says) The short answer is yesvitamin B12 shots do work, but their effectiveness depends heavily on who is receiving them and why

This is the main factor for how long a B12 injection takes to work, offering a significant advantage over oral supplements, which must be broken down by the digestive system before they can be distributed throughout the body

For example, people who maintain a vegetarian or vegan diet, people with absorption disorders, and those taking prescription meds like Metformin, Proton Pump Inhibitors (PPIs), and H2 blockers like Pepcid are often at greater risk

For instance, hydroxycobalamin is stored in the body longer than cyanocobalamin, reducing the need for frequent injections
