The invention relates to methods for determining the level of B vitamins in a test sample. The methods can include the steps of obtaining a water soluble vitamin fraction by extraction in acidic aqueous solution of a test sample, wherein the vitamin fraction comprises one or more B vitamins having at least a predetermined minimum concentration; adding a vitamin standard comprising one or more B vitamins of known quantity to a portion of the vitamin fraction of the test sample, wherein said vitamins in the vitamin standard comprise an isotope label and wherein the vitamin standard is added in an amount sufficient to determine the level of the corresponding vitamins in the test sample; and determining the level of one or more vitamins in the test sample corresponding to one or more of the vitamins in the vitamin standard using mass spectrometry.
