Let us break down these ingredients.

  • Carbonated water is exactly as it sounds, water that has been carbonated.
  • Caramel color comes from plant sources and is vegan.
  • Aspartame is an artificial sweetener and is vegan.
  • Phosphoric acid is food flavoring and is also vegan.
  • Potassium benzoate is a food preservative and is vegan.
  • Caffeine is vegan.
  • Citric acid naturally occurs in citrus fruits.
  • Natural flavor may be sourced from either natural products or animal products. It is unclear where Pepsi sourced its natural flavoring from.
  • Acesulfame potassium is an artificial sweetener. 
  • Phenylalanine is commonly sourced from animal products but may also be found in plants.

Why Diet Pepsi Is Non-Vegan?

The reason why Diet Pepsi is non-vegan may be due to the natural flavor and phenylalanine because we are uncertain if these two ingredients contain animal materials or plant products.

Interestingly, Pepsi has refused to specify which of its ingredients are non-vegan. They have stated that the reason for their refusal to be specific is due to commercial reasons.

Final Thoughts

Diet Pepsi contains a natural flavor and phenylalanine which may be non-vegan but we have no confirmation of this. The refusal of PepsiCo to state which of their ingredients is non-vegan may also potentially point to other ingredients that the company has not disclosed. Vegans should rather opt for other Pepsi drinks that have been confirmed to be vegan.
