|Nutrients||Unit of measurement||Minimum level||Maximum level|
|Vitamin A||International Units||250||750|
|Thiamine (Vitamin B1)||Do.||40|
|Riboflavin (Vitamin B2)||Do.||60|
|Folic acid (Folacin)||Do.||4|

(f) Protein shall be present in an amount not to exceed 4.5 grams per 100 kilocalories regardless of quality, and not less than 1.8 grams per 100 kilocalories of infant formula in the form prepared for consumption as directed on the container when its biological quality is equivalent to or better than that of casein. 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.
