TESTED BY FIRE.
PERFECTED FOR THE SAUNA.

Fire Salt wasn’t dreamed up in a lab—it was forged on the front lines.

Founded by full-time firefighters, Fire Salt is designed for extreme heat—from wildfire lines to sauna benches. When sweat loss hits hard, ordinary hydration isn’t enough. Extreme heat demands a different kind of fuel.

SEA SALT:
NATURE'S HYDRATION SHIELD

A single, 20- minute sauna session can drain liters of sweat. Replacing that loss with plain water only dilutes your system.

Fire Salt uses premium sea salt to help your body hold onto fluid — each stick is scientifically formulated to replace 75% of the average sodium loss in a single sauna session.

POTASSIUM:
THE SECRET TO RECOVERY

That dizzy, wiped-out feeling after heat exposure is potassium loss. Most people lose nearly 200mg in a single session.

Fire Salt replaces the potassium lost in a sauna session to help stabilize your system, reduce inflammation and speed up recovery. Leaving you feeling clear headed and refreshed.

MAGNESIUM:
SWITCH OFF THE STRESS

To get the "Zen" you’re looking for, your nervous system has to shift from the fight-or-flight of the heat to the rest-and-digest of recovery.

Built for the intensity of wildland firefighting, Fire Salt includes 90mg of magnesium malate — the gold standard for addressing physical stress. 50% of Americans are chronically magnesium deficient. Fire Salt fills those gaps and reduces the body stress from high heat exposure.

Fire Salt vs. The Rest

Fire Salt is zero sugar hydration with 3x the electrolytes of the average sports drink, no artificial ingredients, and enough sodium, potassium, magnesium and coconut water to support rehydration under the most intense conditions. Our competitors’ products have too much sugar, too few electrolytes and are full of artificial ingredients. When you rely on hydration performance products to fuel your mission – the cost of getting all of that wrong could be the difference between success and failure.

“I don’t feel wrecked afterward anymore.”

I use the sauna a few times a week and used to leave feeling kind of shaky and drained, even if I drank a ton of water. Fire Salt made a noticeable difference right away. I still get all the benefits of the sauna, but I don’t feel wiped or foggy afterward. It just helps me recover better.

— Alex M.

“This fixed the dizzy feeling for me.”

After longer sauna sessions I would sometimes feel lightheaded or off for a bit. I started using Fire Salt afterward and that basically stopped happening. I feel more normal when I leave — not woozy, not exhausted. It’s simple, but it works.

— Jordan K.

“It makes sauna days feel easier on my body.”

I sauna pretty regularly and Fire Salt just makes the whole experience smoother. I feel more balanced afterward and I don’t crash later in the day. It’s one of those things you don’t realize you need until you stop feeling bad after sauna sessions.
