Hello. Thank you for posting today.
How long vitamin B12 lasts in the body depends on your own individual metabolism and your dietary habits. If you eat a lot of processed foods, the chemicals contained within these products can interfere with your intestinal absorption of this vitamin. Injections bypass that problem. Most injections last up to a month on average. The amount of B12 in your body also depends on how much is stored in your liver.
