TESTED THROUGH TRAINING.
BUILT FOR PHYSICAL RECOVERY.

Fire Salt was created by firefighters, for firefighters who train hard, work long shifts, and put constant strain on their bodies. Designed for repeated physical exertion, Fire Salt supports recovery when soreness and inflammation build over time — something basic hydration alone can’t handle.

POTASSIUM:
THE SECRET FOR INFLAMMATION RECOVERY

Physical activity protects against long-term inflammation — but intense work still spikes short-term inflammation, especially after long days. That’s when soreness and stiffness build and recovery gets harder over time.

During exertion, the body loses 250–300mg of potassium per hour.

Fire Salt delivers 190mg to replace roughly 70% of what’s lost, helping reduce post-work inflammation and joint discomfort.

REDUCING PAIN BY
STABILIZING NERVES.

Inflammation can make nerves hyperexcitable, causing them to fire pain signals more easily and more often — which is why soreness can feel sharper and linger longer after work.

Potassium in Fire Salt helps stabilize nerve signaling, reducing excessive firing and suppressing inflammatory pain pathways. It may also support the body’s natural anti-inflammatory response by influencing cortisol, helping pain and inflammation settle more efficiently after physical strain.

BALANCED HYDRATION
FOR REAL RECOVERY

Sodium is essential for hydration, but excess sodium without enough potassium can increase systemic inflammation and strain blood vessels — especially when hydration isn’t properly balanced.

Fire Salt is formulated with sufficient potassium to help the body excrete excess sodium, counteracting its pro-inflammatory effects while still supporting effective hydration. The result is recovery that replenishes what’s needed — without pushing inflammation higher.

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.

“My recovery between workouts is way better.”

I train hard in the gym a few days a week, and heavy lifting used to leave me sore for days. Fire Salt has helped my recovery a lot. My joints feel better, and I don’t feel as inflamed or tight between workouts. I can train consistently without feeling beat up all the time.

“I’m not as stiff after long shifts anymore.”

I work a very physical job and by the end of the day my knees, back, and shoulders used to feel wrecked. Since using Fire Salt, I notice I’m less stiff after work and the soreness doesn’t hang around as long. I still get tired, but my body feels like it actually recovers overnight now.

“The soreness doesn’t stack up day after day.”

I’m on my feet most of the day and stay active outside of work too. Over time, that soreness used to just stack up and never fully go away. Fire Salt has helped keep that inflammation from building. I feel looser and more comfortable at the end of the week instead of constantly worn down.
