ZestLytes Salty Fruit Electrolyte Hydration Powder Sticks (40-pack, Sugar-Free)

ZestLytes is a newer entrant to the electrolyte-powder market positioned for high-intensity athletes. Each stick delivers 590mg sodium, 330mg potassium, 27mg magnesium, and 900mg chloride—a formula aligned with WHO-recognized oral rehydration standards. The product is sugar-free, naturally flavored with salty-fruit notes, and claims a dual-mechanism hydration system (Fibalance for colon activation, SusCarb for small intestine targeting). It comes in single-serve sticks (40-pack), is vegan, keto, gluten-free, dairy-free, and caffeine-free, and carries NSF and third-party lab certifications. At $0.37 per serving, it sits mid-market. Designed for 1–2 hour high-intensity sessions (marathons, HIIT, heat-heavy work), it's explicitly not marketed as daily hydration due to salt load. Early community feedback suggests it appeals to endurance athletes and keto enthusiasts, though brand recognition remains limited compared to LMNT or Liquid I.V.
