Some conditions, like atrophic gastritis or celiac disease, can block the absorption of B12, while vegan and vegetarian diets can lead to insufficient intake, as animal products are a main source of B12
Fortunately, there is increasing evidence that oral B12 supplements are just as good as injections for raising blood levels in most people ( Vegetarians and vegans are usually advised to take at least 10 mcg per day, or at least 2,000 mcg once per week ( However, some doctors still prefer the use of injections
Conversions between mg, mcg, mL, and insulin syringe units are necessary to determine how many units to draw, how many doses are available per vial, and the estimated duration of your supply
These weekly shots keep building up the bodys vitamin B12 stores, aiding in recovery and preventing deficiency relapse
