Quick answer: The mineral numbers are nearly identical — both deliver 1,000 mg sodium, 200 mg potassium, and 60 mg magnesium per stick, zero sugar, stevia-sweetened. LMNT is cheaper ($1.50 vs. $1.97 per stick) and built around training, keto, and fasting. Suolaa is built around one thing: the sauna. If the sauna is your practice, Suolaa is the one made for it. If you mainly need gym electrolytes that also cover sauna day, LMNT is a fair pick.
Let’s start where most brand comparisons won’t: LMNT is a good product. Its sodium-forward ratio helped correct a decade of watery, sugary sports drinks, and if there’s a box of it in your gym bag, it will do honest work after a sauna too.
So why does Suolaa exist? Because “does honest work after a sauna” and “made for the sauna” are different things — and if the sauna is your practice rather than your recovery hack, the difference shows.
The numbers, side by side
| Suolaa | LMNT | |
|---|---|---|
| Sodium | 1,000 mg | 1,000 mg |
| Potassium | 200 mg | 200 mg |
| Magnesium | 60 mg (citrate) | 60 mg (malate) |
| Sugar / carbs / calories | 0 / 0 / 0 | 0 / 0 / 0 |
| Sweetener | stevia | stevia |
| Sticks per box | 30 | 30 |
| One-time price | $59 ($1.97/stick) | $45 ($1.50/stick) |
| Subscription | from $50.15 first box, then $53.10 | ~$1.30/stick |
| Flavors | Löyly Lemon Lime | citrus, raspberry, orange, chocolate + more |
| Built around | the sauna | training, keto, fasting |
Two honest observations from that table:
LMNT is less expensive. Forty-seven cents a stick less at list. If price decides it, that’s the answer, and we’d rather say so plainly than bury it.
The minerals match. Both formulas are built on the same evidence about what heavy sweat actually removes — roughly five parts sodium to one part potassium, magnesium in support. Sauna sweat is heavy sweat. This ratio is right for it, whichever box it comes in. (The arithmetic: How Much Sodium Do You Lose in a Sauna?)
So what are you choosing between?
Intent. And intent shapes more than marketing.
LMNT is a training-floor product. Its world is CrossFit boxes, fasting windows, ketone meters. The flavors are engineered for a shaker bottle, the voice is performance, the community is athletes. None of that is a flaw — it’s just a different room from the one with the kiuas in it.
Suolaa is a sauna product. Suolaa is a Finnish-style electrolyte made specifically for sauna use — 1,000 mg sodium, 200 mg potassium, 60 mg magnesium per stick, zero sugar. The name is Finnish for salt. The flavor is named for löyly, the steam off the rocks. The serving ritual assumes a cold liter after the last round, not a mid-WOD gulp. It’s sold where sauna people actually are — including in the bathhouses themselves — and the whole brand speaks sauna as a first language, because it’s the only language we speak.
No sugar. No carbs. No calories. Nothing fake — and nothing borrowed from a gym bag.
The honest recommendation
- You sauna weekly or more, and it’s a practice you care about → Suolaa. It was formulated, flavored, and priced for exactly this, and the two dollars a week difference buys a product that treats your ritual as the main event.
- You’re a gym-first person who saunas occasionally → LMNT covers both jobs adequately. Add Suolaa when the sauna stops being occasional.
- You’re deciding purely on price → LMNT one-time, or note that Suolaa’s 6-pack ($299, $1.66/stick) and subscription (from $1.67/stick) close most of the gap.
FAQ
Is LMNT good for the sauna? Yes. Its 1,000 mg sodium serving suits heavy sweating, sauna included. Suolaa uses the same sodium-forward ratio and is designed specifically around the sauna ritual.
What’s actually different if the formulas are so close? Magnesium form (citrate vs. malate), flavor direction, and everything around the formula: what it’s flavored for, where it’s sold, and what the brand is about. Suolaa is sauna-only by design.
Is Suolaa just LMNT with a Finnish name? The mineral ratio reflects the same sweat science — we consider that table stakes, not a differentiator. What you’re choosing is a product and brand built for the sauna rather than the squat rack.
Which tastes better? Taste is yours to judge. We’d only say Löyly Lemon Lime was tuned for cold water after heat — clean and light, no shaker-bottle sweetness.
Suolaa — Finnish for salt. The sauna takes something. SUOLAA gives it back. Shop the Box of 30 →
