Infant Formula Substitution Guide

The table here provides categories of formulas for premature and term infants. Formulas within each category are comparable and safe to substitute for each other, in case of shortages. Any substitution should only be done under the recommendation and supervision of a healthcare professional.

Please be aware that formula mixing instructions, including proper ratios of powder to water, can vary significantly. Follow all mixing instructions on the container. Use the specific scoop that comes with each can.

NASPGHAN does not endorse any specific formulas, nor the general use of formula over possible use of human milk as the optimal source of infant nutrition.
