Is the phenylalanine present in Coca-Cola Zero Sugar a concern for individuals with phenylketonuria (PKU)?

Yes. The product uses aspartame, which breaks down into phenylalanine, and the label lists phenylalanine as a trace ingredient, so people with PKU should avoid or limit consumption.

Is Coca-Cola Zero Sugar suitable for vegan, keto, and low-sugar diets?

The drink contains no sugar, no fat and only trace calories, making it compatible with keto and low‑sugar diets; all listed ingredients are plant‑based or synthetic, and no animal‑derived components are declared, so it is generally regarded as vegan‑friendly, although some flavourings are labeled "maybe" regarding vegan status.
