9th Circuit Revives False Advertising Suit Over ‘Zero Calorie’ Supplement

In a significant ruling affecting dietary supplement manufacturers, the U.S. Ninth Circuit Court of Appeals recently revived a false advertising lawsuit concerning a supplement marketed as “zero calorie.” The plaintiff alleged that the product’s labeling was deceptive, specifically disputing the “zero calorie” claim despite the presence of caloric content derived from ingredients like sugar alcohols.

This decision, reported by Law360, underscores the growing regulatory scrutiny surrounding dietary supplement labeling accuracy, especially as consumers increasingly seek transparency on health and nutrition claims. The ruling also highlights the critical role that rigorous product testing and regulatory compliance processes play in substantiating advertising claims.
