Shop for Supplements

The Dempster Clinic acknowledges the importance of nutrients from a whole food diet, but also believes that the body needs supplementation to optimize your health and cellular rejuvenation. In most cases, the body has difficulty getting all of the nutrients it needs from diet alone due to the chemicals in our food and in our environment. These chemicals cause added stress that interfere with proper digestion and detoxification of harmful toxins that can cause chronic disease and weight gain.

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.
