Term Infants Fed Exclusively with Donor Milk May Require Vitamin C Supplementation. (CIHR-FDN#:143233).
2021
Background When there is insufficient mother's milk for preterm infants, fortified human donor milk (DM) is the preferred supplement. Recently, there is growing interest in providing DM to term infants. Aside from vitamin D, mother's milk is a complete source of nutrition for term infants. It is unknown whether supplementation of micronutrients is required for term infants exclusively fed DM, particularly nutrients affected by heat processing, such as vitamin C. The objective of this study was to determine the total vitamin C content in DM and whether it would be adequate for an infant exclusively fed DM. Methods DM samples (n = 56) were collected at a Canadian milk bank from April to August 2018. Vitamin C concentration was determined by high-performance liquid chromatography. Results DM samples had a vitamin C concentration of 17.7±9.8 mg/L (mean ± SD) and were variable, ranging from 1.9-43.2 mg/L. Using these values and assuming an exclusive DM consumption of 780mL/day, the estimated vitamin C intake would be 13.8±8.6 mg (mean ± SD), falling below the Adequate Intake of 40 mg/day for infants (0-6 months). Conclusion Vitamin C supplementation is required for all infants if DM is the sole source of nutrition. Future studies should investigate other heat and light-sensitive nutrients.
