To the Editor: Large errors in the stated vitamin K contentof milks and formulas seem worth correcting (Sept. 23 issue)¹.Human milk averages about 3 µg per liter,²^,³ not 20 ngper liter. Cow's milk is only two- or threefold higher⁴ (not15 to 17 mg per liter, or 10⁶-fold higher). The commonly usedinfant formulas contain 54 to 105 µg per liter at 20 kcalper ounce (not 830 mg per liter).
