VITAMIN B12 Cyanocobalamin: Energy, healthy nerve cells. 10 SHOTS

Cyanocobalamin works by increasing your levels of vitamin B12.  You need vitamin B12 to make red blood cells and keep your nervous system healthy. However, you may also need vitamin B12 injections at first to boost your levels. It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. Some people may be able to stop taking cyanocobalamin when their vitamin B12 blood levels are back to normal. You may have regular blood tests while taking cyanocobalamin, to monitor the levels of vitamin B12 in your blood.
