FDA Approves Natural Blue Dye for Foods, Urges Faster Exit from Red No. 3

In a move aimed at improving food safety and transparency, the U.S. Food and Drug Administration (FDA) has approved the use of gardenia (genipin) blue as a color additive in various foods, while simultaneously urging manufacturers to speed up the phase-out of synthetic dye FD&C Red No. 3. According to a press release issued by the FDA on July 14, the natural blue dye is the fourth plant-based coloring approved in the past two months, reflecting a significant push by the Department of Health and Human Services to eliminate petroleum-based dyes from the U.S. food supply.

The newly approved gardenia blue, derived from the fruit of the gardenia plant, can now be used in sports drinks, flavored water, fruit beverages, teas, and candy. The FDA’s decision aligns with the Make America Healthy Again initiative, spearheaded by HHS Secretary Robert F. Kennedy, Jr., which prioritizes reducing synthetic chemical exposure—particularly in foods marketed to children. The agency emphasized that the approval was based on toxicological evaluations, projected dietary exposure, and scientific literature, meeting safety standards required under the Federal Food, Drug, and Cosmetic Act.

In addition to the gardenia blue approval, the FDA issued a letter encouraging food manufacturers to stop using FD&C Red No. 3 in products—including dietary supplements—sooner than the current January 15, 2027 deadline. This recommendation builds on a growing movement within the food industry; roughly 40% of food companies have already committed to phasing out synthetic dyes voluntarily. The national trade group Consumer Brands also recently pledged to remove synthetic FD&C colors from all food and beverage items served in schools by the 2026–2027 school year.

The FDA has also recently approved other natural color additives, including blue from Galdieria sulphuraria algae, butterfly pea flower extract, and calcium phosphate. These alternatives offer manufacturers a growing selection of natural dyes to replace petroleum-based ones in compliance with evolving regulations and consumer expectations.
