This document specifies a method for the simultaneous quantitative determination of four water-soluble vitamins in infant formula and related nutritional products, including relevant forms of vitamins B1<\/sub>, B2<\/sub>, B3<\/sub> and B6<\/sub> by enzymatic digestion and UHPLC-MS\/MS. This document is not intended to be used on products where vitamins have not been added.<\/p>\n
