California will prohibit stores and online sellers from selling over-the-counter diet pills and dietary supplements marketed for weight loss or muscle building to anyone under 18 without a prescription. Gov. Gavin Newsom signed the measure, Assembly Bill 2030, on Sept. 28 as part of a package of health bills that also created a state label for foods that are not ultra-processed.
The governor's office said nearly 1 in 10 adolescents have used these products and that young people who use over-the-counter diet pills are six times more likely than nonusers to be diagnosed with an eating disorder within three years. California is the second state to restrict these sales to minors, following New York, whose law took effect in April 2024, NutraIngredients reported.
