About FD&C Yellow #5
FD&C Yellow #5 (Tartrazine) is a synthetic azo dye widely used as a yellow colorant in food, medications, and supplements. While effective in imparting color, it is a known allergen for some individuals, potentially causing hives, itching, and more severe reactions. Its association with hyperactivity in children is debated, but some evidence suggests a possible link, particularly when combined with other artificial additives. Due to potential adverse effects, regulatory agencies monitor and control its use.
