It is 2026, so is Diet Pepsi vegan yet? Here’s what the evidence says about Diet Pepsi – and whether it’s vegan. The short answer: No, Diet Pepsi is not vegan.
Is Diet Pepsi Vegan?
What we know?
The company behind Diet Pepsi, PepsiCo, states on its website that most of its sodas are suitable for vegans – except Diet Pepsi.
Why it’s not vegan?
PepsiCo has refused to reveal the “secret non-vegan ingredient,” calling it “commercially sensitive.”
Speculation guesses this may come from use of animal-derived processing aids (e.g. gelatin, casein, isinglass) or non-vegan sweeteners/colour-processing components – though none appear explicitly on the ingredient list.
So it is most likely hidden in the blanket term – Flavorings.
Does this vary by country?
Our readers and Keru App users are mostly from USA and UK, including Canada and other regions. So the question arises – Is it non-vegan in all regions?
The answer is Yes. Verdict is the same globally: According to PepsiCo’s international site, Diet Pepsi is the only soda from them that is declared non-vegan.
Because we don’t know what the non-vegan part is, even in places where ingredient lists look “normal,” it’s safest to assume Diet Pepsi is not vegan.
