Is Starry Lemon-Lime Soda Vegan?
Vegan
Not certifiedStarry is PepsiCo's lemon-lime soda that replaced Sierra Mist in 2023. The regular formulation contains carbonated water, high fructose corn syrup, citric acid, natural flavor, potassium benzoate, potassium citrate, and calcium disodium EDTA, no animal-derived ingredients appear on the label, no allergen statement lists dairy or egg, and there is no carmine, gelatin, honey, or whey. Starry Zero Sugar swaps the sweetener for aspartame, acesulfame potassium, and sucralose, all of which are synthesized rather than animal-sourced, though they carry a historical animal-testing footnote that some strict vegans find objectionable.
The catch: The "natural flavor" listing is unspecified by PepsiCo. For lemon-lime sodas this is almost certainly citrus-derived, but PepsiCo has not publicly confirmed this in writing for Starry specifically. Ingredient checkers flag it as "maybe" vegan on this ambiguity alone, not because any animal-derived flavor is confirmed.

Verdict
Vegan
Brand
PepsiCo
Regular Starry uses high fructose corn syrup and is free of any identified animal ingredient. Starry Zero Sugar uses aspartame, acesulfame potassium, and sucralose.
These sweeteners are not animal-derived, but all three underwent animal testing during their original FDA safety review in the 1970s-1990s. Most vegan dietary frameworks focus on ingredient sourcing rather than historical testing policy, so the majority of vegans would consider Zero Sugar acceptable too.
Neither variant carries a vegan or vegetarian certification from PepsiCo. com, but Starry was not confirmed present on it in searches as of mid-2026, the page uses a dynamic loader that did not render fully.
No third-party vegan certifying body stamp appears on the can. If absolute certainty matters, contacting PepsiCo consumer affairs is the only way to pin down the natural flavor origin.
