（c） Any vitamin K added shall be in the form of phylloquinone.

If the biological quality of the protein is less than that of casein, the minimum amount of protein shall be increased proportionately to compensate for its lower biological quality. For example, an infant formula containing protein with a biological quality of 75 percent of casein shall contain at least 2.4 grams of protein （1.8/0.75）. No protein with a biological quality less than 70 percent of casein shall be used.
