Our read on this product

The formula relies heavily on artificial additives like Caramel Color (E150d) and Phosphoric Acid, which contributes to the product's 35/100 health score. While the use of Aspartame and Acesulfame-K provides sweetness without glucose spikes, these non-nutritive additives offer no biological benefit. We recommend prioritizing whole-food hydration over these synthetic, nutrient-void formulations.

Best for

This beverage is intended for adults looking for a zero-calorie, caffeine-free alternative to traditional sodas.

Approach with care

Individuals sensitive to artificial sweeteners or those looking to minimize intake of synthetic food dyes and phosphoric acid should avoid this product.
