Expert analysis

Our read on this product

This beverage features a clean base of purified water and organic brewed yerba mate, providing valuable polyphenols and natural antioxidants. However, the inclusion of organic cane sugar contributes to 6.5g of sugar per 100ml, which impacts its overall health score of 65. The addition of organic prune, lime, and tangerine juices enhances the nutrient profile with vitamins, yet the added caffeine standardizes the stimulant effect. Environmentally, the product performs exceptionally well with an 85/100 score, thanks to Guayakí's commitment to regenerative agriculture. While it is a better-for-you alternative to synthetic energy drinks, consumers should remain mindful of the total sugar intake.

Best for

Approach with care
