Intravenous administration of nutrients can achieve serum concentrations not obtainable with oral, or even intramuscular administration.

IV nutrient therapy may be more effective than oral or intramuscular treatment for correcting intracellular nutrient deficits. Some nutrients are present at much higher concentration in the cells than the in the serum. 

If cells are repeatedly flooded with nutrients, the improvements may be cumulative. Patients who receive a series of IV injections become progressively healthier. The interval between treatments can be gradually increased, and eventually IV’s are no longer necessary. Others require regular injections for an indefinite period of time in order to control their medical problems.

Many relatively healthy patients choose to receive periodic IV’s because it enhances their overall well being for periods of a week to several months.
