Summary

Starbucks launches protein drinks

Starbucks introduced eight protein drinks in September 2025 as part of its “Back to Starbucks” menu overhaul.
Starbucks markets the drinks as protein-packed with no added sugar, though they contain natural lactose from milk.

Recent industry trends show rising lawsuits over “sugar-free” labeling, including cases involving the sweetener allulose.

History

Historical Context

Since the 1906 Pure Food and Drug Act gave the FDA authority to police mislabeling, the agency later required Nutrition Facts panels in the 1990s and expanded nutritional labeling on packaged foods. That legacy underpins the 2025 Seattle lawsuit in which Hagens Berman challenges Starbucks for marketing a 21-gram-sugar protein drink as “sugar-free.”
