What is Intravenous Vitamin Therapy?

Intravenous Vitamin Therapy is the infusion of vitamins, minerals, amino acids, and other natural substances directly into the vein.  Bypassing the digestive system is the main advantage of IV nutrition.  When substances are given orally they must be processed through the stomach, liver, and intestines.  Many substances may be rendered inactive in the digestive tract, or may not be well absorbed due to poor intestinal function.  By directly administering nutrients to the bloodstream, therapeutic doses of nutrients in blood levels can be absorbed more effectively.  It is important to note that each treatment is customized to the patient’s individual needs.

Can all naturopathic doctors in Ontario administer Intravenous Vitamin Therapies?

Not all naturopathic doctors in the province of Ontario can administer IV Vitamin Therapies.  Naturopathic doctors must take an accredited IV Therapy course and complete both practical and written exams set out by the College of Naturopaths of Ontario (CONO).  Dr. Dempster, ND is licensed to practice IV Vitamin Therapy and offers this service at his Toronto-based clinic.
