Multivitamins are vital and necessary nutrients for all patients, especially during acute illness and include the fat-soluble vitamins (i.e., A, D, E, and K) and the water soluble vitamins, B-vitamins (e.g., B-1, B-6, B-12, etc.), Vitamin C and folic acid. For delivery into the stomach or intestine of adults, for example, standard amounts equal to the recommended dietary allowances (RDAs) are often provided in pre-mixed products by the manufacturer and usually met when approximately 1500 kcals of the commercial formula are given daily. For intravenous delivery, specific amounts of these are included in a single commercial sterile product, as recently established by the Food and Drug Administration or FDA, and are added by the Pharmacy each day.
