Vitamin injections are concentrated doses of essential vitamins and nutrients delivered directly into your muscle tissue for rapid absorption
Vitamin B12 Injection Therapeutic indications Vitamin B12 Injection is mainly used for the treatment of Vitamin B12 Deficiency in pernicious anemia with or without neurological complications
Some people just feel much better with regular weekly or biweekly B12 shots, even if not deficient
All I can say is that I'm basically a case of a doctor being indifferent by recommending a patient take vitamin b12 tablets in addition to b12 injections...which allowed a severe reaction to take place that is ongoing
