Subway Welcomes Two Flavors of poppi Prebiotic Sodas

— May 6, 2026 — Marketing
Subway has introduced two flavors of poppi prebiotic sodas — Strawberry Lemon and Orange — into its nationwide beverage lineup. This strategic addition to the quick-serve restaurant's existing menu represents a shift for the sector as the company moves away from traditional high-sugar sodas toward functional drinks.

The poppi prebiotic sodas are popular among health-conscious consumers as they contain only five grams of sugar and include prebiotics, which are known to support digestive health.

All in all, by partnering with poppi, a brand that has gained significant cultural traction and celebrity endorsement, Subway allows customers to pair a customizable sandwich with a soda that aligns with health-conscious lifestyles. To celebrate the partnership, Subway is offering a limited-time promotion, where Sub Club loyalty members can get a free can on May 7th.
