The Take

Guaraná Antarctica Zero is not healthy. It earns an 88 slop score for replacing sugar with a double hit of aspartame and acesulfame K plus caramel color and sodium benzoate.

People buy it to signal fitness and discipline while coping with the same ultra-processed cravings they claim to escape.

The Verdict

Skip Guaraná Antarctica Zero. The zero sugar marketing masks a full chemical stack that ghosts your microbiome while delivering fake energy.

Buy LMNT instead. Exact slop score: 88.
