  1. Abbreviations: EF, experimental formula; EU, European union; Min, minimum; Max, maximum; SF, standard formula.
  2. aNutrient composition analyzed by Covance Laboratories, Madison, WI, USA; total protein calculated as total nitrogen × 6.25.
  3. bCodex and EU recommendations for infant formula composition are based on a compilation of published literature values on human milk composition.
  4. cThe concentration of methionine and cystine/cysteine may be added together if the ratio between methionine and cystine is not greater than 2.
  5. dThe concentration of tyrosine and phenylalanine may be added together if the ratio between tyrosine:phenylalanine is not greater than 2.
