Following the ban of red dye No. 3 in the United States, experts weigh in on the potential health risks of red dye No. 40, yellow No. 5 and others.

Red Dye No. 3, also known as erythrosine, is a synthetic food dye that gives foods and drinks a bright red color. It is also sometimes used in oral medicines and dietary supplements. It first was approved for use in food in 1907. It's made from petroleum.

The FDA's ban on FD &C Red No. 3, also known as Red 3, will not go into effect until January 2027 for food products and beverages and January 2028 for consumable medications, meaning products containing Red 3 will still be on the market for the next two years.
