Bottom line: Nuun Sport's 1g sugar and 10 calories is right for sustained hiking where you are already eating food for energy. Liquid IV's 11g sugar and 45 calories is better for post-hike recovery or serious dehydration. Using Liquid IV all day during hiking means unnecessary sugar intake. Use the right product for the right situation.

Can I use Liquid IV while hiking?
Yes, but it is not optimized for it. Liquid IV's 11g of sugar and 45 calories are appropriate for recovery, not sustained activity where you are already eating. Nuun Sport (1g sugar) is the better on-trail choice. Liquid IV belongs in your car or at camp for post-hike recovery.
Is Nuun Sport enough electrolytes for hot-weather hiking?
For moderate hot-weather hiking: yes. For heavy sweating on very hot days (90°F+, 10+ mile days): Skratch Labs at 380mg sodium per serving is a better choice. Nuun's 300mg is solid for most conditions.
Which has more sodium — Nuun or Liquid IV?
Liquid IV has more sodium: 500mg vs Nuun's 300mg per serving. For acute rehydration: Liquid IV's higher sodium is better. For sustained hiking hydration: Nuun's 300mg is appropriate without excess sugar.
