Abstract
The stability of folic acid in a variety of solutions used for parenteral nutrition has been determined over a 2-wk period. Provided that the acidity of the solution remains above pH 5.0 the folate, in the concentrations usually used for parenteral nutrition, will remain stable in solution, and all of the folate added to the solution will be delivered to the patient. The applicability of this in vitro work to a group of patients requiring parenteral nutrition was assessed, in order to determine a suitable dose. A dose of 0.2 mg of folic acid daily was inadequate to meet the requirements of these patients. In contrast a dose of 1.2 mg daily for 7 days was sufficient to cause an increase in the serum folate concentration. (Journal of Parenteral and Enteral Nutrition8:3-13, 1984)
