How Do B12 Injections Work?
B12 injections work by delivering a concentrated dose of vitamin B12 directly into the muscle, allowing for rapid absorption into the bloodstream. This method bypasses the digestive system, making it an effective treatment for individuals who have difficulty absorbing B12 through their diet or oral supplements. Once in the bloodstream, B12 is transported to the cells, where it plays a vital role in energy production, red blood cell formation, and neurological function.
The injection typically contains cyanocobalamin or hydroxocobalamin, two forms of vitamin B12 that are easily absorbed by the body. By replenishing B12 levels, these injections can help alleviate symptoms associated with deficiency, such as fatigue, weakness, and cognitive issues. Regular B12 injections may be required to maintain adequate levels, depending on the underlying cause of the deficiency.
