Requirement and criteria of adequate vitamin supply in healthy newborns.

Abstract

Studies of the relationship between urinary excretion of vitamins and their daily intake in healthy newborns showed that babies aged 3-10 days should receive 30 mg vitamin C, 0.24 mg vitamin B(2), and 0.13 mg vitamin B(1). The criteria of adequate vitamin C, B(1), and B(2) supply evaluated by their urinary excretion are 220.0, 0.7, and 1.4 mg/g excreted creatinine, respectively.
