As people become more health conscious, they turn to vitamins to boost their health. However, taking vitamins orally, in pill form, may not be the best solution for everyone. For instance, if you experience digestive problems, it becomes more difficult for you to gain the full benefits from the vitamins in pill form. This is because the ability of the body to absorb them is impaired. Those taking medications may also have difficulty as the medications can cause difficult with absorption and lead to higher excretion of vitamins out of the body. This is the reason doctors are resorting to IV nutrient therapy.
