Standard Method Performance Requirements (SMPRs) for Determination of Folic Acid in Dietary Supplements

AOAC SMPR 2022.002 defines the method performance requirements for accurately measuring folic acid in dietary supplements. These include capsules, tablets, powders, and liquid supplements. The method allows for the use of liquid chromatography with UV, DAD, or mass spectrometric detection. Selected systems must achieve high sensitivity, precision, recovery, and selectivity to differentiate folic acid from degradation products and matrix interferences, ensuring the accuracy needed for label claim verification.
