Many patients with chronic diseases, autoimmune conditions, and environmental poisoning e.g. Chronic fatigue immunodeficiency syndrome (CFIDS); Mercury poisoning; Fibromyalgia, and others, also have abnormal gastrointestinal absorption of nutrients. These patients may take apparently adequate doses of oral vitamins but these do not get absorbed in beneficial amounts. Therefore, these patients need these important vitamins and nutrients administered to the body in a way that bypasses the gastrointestinal tract. Therefore, relatively large doses of several vitamins and nutrients (vitamin C, B complex, minerals, etc) are then added to a bag of sterile saline solution and administered through a vein into the body over a period of about one hour. This has excellent effect in boosting the immune system and helping the body heal.
