Vitamin B Complex Injections

The promoters of vitamin B complex injections are of the opinion that they are more effective in providing vitamin B to the body than other modes of administration (tablets and gels). According to them, the body enzymes and acids alter the molecular structure of the vitamins once they are ingested. In recent times, many weight conscious people are opting for vitamin B12 injections for weight loss. The injections are administered parenterally, mostly through intramuscularly or intravenously. They are more expensive than other B complex forms.
