Food,
Drug, & Cosmetic (FD&C)
dyes are synthetic color additives used in food,
prescription drugs and over-the-counter medicines (OTCs). Consumption of FD&C
dyes has been associated with neurobehavioral behavior in some children. The amount of
dye used in commercial products is proprietary, making it difficult to assess dietary intake and determine exposure in children. To date, no studies have examined FD&C
dyes in OTCs or
vitamins in the United States. To address this,
FD&C Red No. 40, Yellow No. 5, Yellow No. 6,
Blue No. 1, and Blue No. 2 levels were measured in prenatal
vitamin tablets, children's chewable and gummy
vitamins,
pain reliever
tablets and syrups, and
cough/cold/
allergy tablets and syrups.
Dyes were isolated using solid phase extraction (SPE) and quantified by high performance liquid chromatography (HPLC).
Dye levels varied between products with highest levels in
pain reliever and
cough/cold/
allergy syrups. Significant variability was observed within some brands. Degradation of Red No. 40,
Blue No. 1, and Yellow No. 6 was observed in the
vitamin gummies. Intake of
FD&C Red No. 40 is two times the US FDA ADI (accepted daily intake) for some children's
pain reliever syrups and almost three times the US FDA ADI for some
cough/cold/
allergy syrups.
