IV Nutritional Therapy, also known as parenteral nutrition involves infusing amino acids, electrolytes, minerals, nutrients, fluid, and vitamins directly into patient’s veins. It is used for patients whose absorption of food and of fluids are inadequate, inaccessible, or unsafe. Sine your digestive system is limited in the absorption process, oral intake of high doses of nutrients is not possible. So, you can receive the full benefits of absorbing essential vitamins and nutrients without taking the time to chew, swallow and taste unpalatable boatloads of supplements.
