Short answer: For most people, Fire Salt is the better everyday electrolyte. It has 50% more magnesium than LMNT (90 mg vs 60 mg), adds coconut water, costs less per stick on a single box ($1.41 vs $1.50), comes in caffeine and creatine versions, and is made in the USA by a brand founded by firefighter Brady Johnson. LMNT carries more sodium (1,000 mg vs 670 mg), which suits extremely salty sweaters.
Both are zero sugar, stevia-sweetened and come in single-serve sticks. Here's how they compare. Fire Salt publishes this comparison.

Why most people pick Fire Salt
- 50% more magnesium. 90 mg vs 60 mg per stick.
- Coconut water in every stick. LMNT doesn't include it.
- Less salty, every day. One-third less sodium per stick means a milder drink at the same water volume. If you've found LMNT too salty to drink daily, this is the difference. 670 mg is still a real dose: mixed in 32 oz, it's about 708 mg per liter, inside the 0.5 to 0.7 g per liter range the American College of Sports Medicine suggests for exercise over an hour.
- Caffeine and creatine on the same base. Hydration + Caffeine has 100 mg caffeine, twice LMNT's tea flavor. Electrolytes + Creatine adds 5 g creatine monohydrate. LMNT's drink mix page doesn't list a creatine version.
- Lower single-box price. $1.41 vs $1.50 per stick, and you get 32 sticks instead of 30.
- 11 flavors plus a variety pack.
- Made in the USA, founded by firefighter Brady Johnson. See Best Electrolytes for Firefighters. Sold at Scheels stores and on Amazon.
- HSA/FSA eligible through Truemed.
"Would buy again as the flavors are solid and I like that they are not quite as salty as something like LMNT and are a bit less expensive..." (Bradley O., 5-star review on drinkfiresalt.com)
Where LMNT fits
LMNT carries more sodium (1,000 mg) and sells an unflavored, unsweetened version. If you're an extremely salty sweater or avoid sweeteners entirely, LMNT works.
Looking for an LMNT alternative?
Fire Salt is the LMNT alternative to try if LMNT tastes too salty or you want more magnesium. You get 30 mg more magnesium, coconut water, caffeine and creatine versions, and a lower single-box price. Not sure? Start with the 6-stick sampler ($11.99).
A note on sodium
More isn't automatically better. It depends on how much you sweat. The American College of Sports Medicine suggests about 0.5 to 0.7 g of sodium per liter during exercise longer than an hour. The National Wildfire Coordinating Group suggests 100 to 850 mg per liter for supplemental drinks on the fireline. Mixed in 32 oz, Fire Salt is about 708 mg per liter and LMNT is about 1,057 mg per liter. If you have high blood pressure, kidney issues, or are on a sodium-restricted diet, talk to your doctor before using any high-sodium electrolyte.
