Coca-Cola zero

About this product

This product carries a wellbeing score of 58%, placing it slightly above neutral for a beverage, and a safety score of 87%, indicating a generally favorable safety profile for its category. The wellbeing score reflects a modestly positive balance of hydration and refreshment with minimal nutritional contribution, while the safety score suggests that typical consumption poses low overall risk for most adults.

Water serves as the primary base, delivering hydration and acting as the solvent for all other components. Carbon Dioxide provides the characteristic effervescence that enhances mouthfeel and refreshment. The Sweeteners—aspartame and acesulfame-K—supply sweetness without added sugar or calories, supporting the product's zero-sugar positioning. Caffeine contributes a mild stimulant effect that many consumers seek in cola-style beverages.

The most notable concerns center on caffeine, which carries medium acute toxicity and pregnancy-related risk at higher intakes, and Caramel (E150d), which contains trace levels of 4-MEI, a potential contaminant with low-level lymphocyte effects at high doses. Aspartame also warrants mention due to a low phenylketonuria (PKU) risk for individuals with that condition, alongside low-level cancer signal and pregnancy caution flags. These concerns are generally low in magnitude for moderate consumption.

Overall, this product offers a reasonably safe, calorie-free refreshment option with a slightly positive wellbeing profile, though individuals sensitive to caffeine or phenylalanine should consider their intake accordingly.
