Zinc Gluconate And Blue 1

Zinc gluconate is a zinc salt of gluconic acid, which is a naturally occurring acid found in fruits, honey, and wine. It is often produced through fermentation. Blue 1, also known as Brilliant Blue FCF, is a synthetic organic dye, meaning it is man-made and produced from petroleum.

Zinc gluconate is used as a source of the essential mineral zinc in dietary supplements, fortified foods, and lozenges. Blue 1 is added to give a blue color to a variety of foods and beverages, including candies, soft drinks, and baked goods.

Zinc gluconate is considered Generally Recognized As Safe (GRAS) by the FDA for use as a nutrient supplement. Zinc is an essential mineral, and the US National Academies sets Upper Intake Levels (ULs) for vitamins and minerals. JECFA has evaluated zinc compounds and set an acceptable daily intake. Blue 1 is approved by the FDA as a color additive for food, drugs, and cosmetics. JECFA has evaluated Blue 1 and set an acceptable daily intake. In April 2025, the FDA announced a plan to phase out petroleum-based synthetic dyes, including Blue 1. Some studies have suggested a link between synthetic food dyes and hyperactivity in children, though evidence is mixed.
