Over a full shift
Six hours of hard work means about six Fire Salt sticks, or about 4,000 mg sodium and 0 g sugar. To get that much sodium from 20 oz Gatorades, you'd need about 15 bottles, or roughly 500 g of sugar. Even matching bottle for bottle, six Gatorades is 204 g of sugar.
Where Fire Salt wins
- About 2.5x the sodium of a 20 oz Gatorade, with zero sugar.
- More potassium, plus magnesium and calcium.
- Dosing built for work. One stick is formulated to replace what the average person loses in about an hour of significant exertion, so use one stick per hour of hard work.
- Light to carry. A box of sticks fits in a lunch box. A case of bottles doesn't.
- Versions for early starts and lifters: Hydration + Caffeine and Electrolytes + Creatine.
- Made in the USA, with 10% of profits going to first responders. Rated 4.8 stars across more than 1,000 Amazon reviews, and the highest-GMV electrolyte stick pack on TikTok Shop from January to September 2026, per Kalodata.
