Why Zero Sugar Matters in an Electrolyte Powder
Sugar in a hydration drink is mostly there for two reasons: taste and shelf appeal. Neither helps you hydrate.
In fact, added sugar actively works against the goal:
- Sugar pulls water into the gut, slowing absorption
- It spikes insulin, which crashes your energy 60-90 minutes later
- Daily sugar in a "wellness" product adds up — 11g per stick × 2 packs/day × 30 days = 660g of added sugar a month from one habit
If you're taking electrolytes for performance, recovery, or to feel better — zero sugar isn't a preference. It's the right tool for the job.
