Our ability to digest and absorb the vitamins and minerals from our food changes throughout our lives. As we age, absorption of nutrients is compromised because we have decreased stomach acid production, diminished digestive enzyme activity and more gastrointestinal inflammation. We need nutrients for nearly every biological function and chemical reaction that takes place in our bodies. Although oral supplementation of these key nutrients can certainly help, we still may not absorb them adequately. However, IV therapy is delivered directly into the bloodstream, bypassing the stomach and intestines, and delivering high concentrations of nutrients in the fastest and most absorbable manner to your cells. Intramuscular (IM) vitamin injections follow IV infusions in terms of their delivery and absorption rate, and are a quick and convenient way to improve your nutritional status.
