Kitletics Review · 8.0 Good
High5 ZERO Electrolyte Tablets is a electrolyte tablet/capsule (0 g carbs/serving; no caffeine; 250 sodium). Near-zero-calorie electrolyte tablets for bottles — designed when you want light flavour and electrolytes without adding meaningful carbs to a gel-based fueling plan. I'd shortlist it for zero-carb bottle option alongside separate gels. The trade-off is not a carbohydrate fuel — Nuun Sport Electrolyte Tablets is the cleaner compare when that is most of your week. It fits buyers who actually need a electrolyte tablet/capsule (0 g carbs/serving; no caffeine; 250 sodium), not a one-product rotation.
