Our read on this product

The 35/100 health score reflects the inclusion of additives like Aspartame, Acesulfame Potassium, and Phosphoric Acid. While the drink is sugar-free, Phosphoric Acid is linked to potential long-term concerns regarding bone density. The formula is purely functional for flavor and shelf-stability rather than providing health benefits. Regular consumption of ultra-processed beverages like this one is generally discouraged by nutrition experts.
