Citric acid

A naturally occurring acid from citrus fruit — used to balance flavour.

About

Citric acid is an organic acid found naturally in citrus fruits such as lemons, limes, and grapefruit. It is one of the most widely used ingredients in the food and beverage industry, serving as an acidity regulator, flavour enhancer, and natural preservative.

In TWOZERO®, citric acid plays a crucial role in balancing the flavour profile of each variety — sharpening the natural fruit extracts and creating the clean, refreshing tartness that makes the drink feel light rather than heavy or sweet. Beyond taste, citric acid is a molecule your body already produces and uses every day as part of the Krebs cycle — the core energy pathway that converts the nutrients you eat into the fuel your muscles run on. Commercially, citric acid is produced through the fermentation of carbohydrate sources and is chemically identical to the citric acid found naturally in fruit.
