how often do you get vitamin b12 injections What Are the Benefits of Injections? Benefits of Vitamin B12 Injections

The Centers for Disease Control and Prevention (CDC) states that if a multi-dose vial has been opened or accessed (e.g., needle-punctured) the vial should be dated and discarded within 28 days unless the manufacturer specifies a different (shorter or longer) date for that opened vial

And honestly, for most people, that probably means taking reasonable doses, timing them well, making sure you have adequate folate and other supporting nutrients, and checking in with your healthcare provider periodically to make sure everythings on track.

If you follow a vegan diet, B12 is not found naturally in fruit, vegetables or grains, so fortified foods or a supplement matter more, and seaweed, spirulina and similar products are not reliable sources

For patients who have difficulty absorbing B12 through the digestive tractsuch as those with pernicious anemia, gastrointestinal disorders (like Crohns disease or celiac disease), a history of gastric bypass surgery, or those with severe B12 deficiencyour providers often recommend intramuscular B12 injections
