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 efficiently.  It is important to note that each treatment is customized to the patient’s individual needs.

When Lab Tests Fail: Secrets Behind Your Lab Results

The moment you get your lab results is always filled with a strong sense of trepidation and hope. You fear the worst, but you also hope for the best. This is simply human nature that I have observed over and over in my practice.  What usually happens next is that the patient anxiously skims through the paper, making sure that every number falls into a “normal range”, which is so kindly provided in the lab results. After that they either sigh with relief (because everything seems “normal”) or look alarmed, thinking that even one deviation from the “norm” can ruin
