Felt so much better after using the sauna with this and there's no strong aftertaste like LMNT.

No more 2am cramping after long sessions. This actually does what normal electrolyte brands couldn't.

Questions answered
The honest answers.
How is this different from LMNT?
Same sodium (1,000mg). But we run 2× the potassium (400 vs 200mg), 1.67× the magnesium (100 vs 60mg), and add 250mg of vitamin C that LMNT doesn't include. The ratios are calibrated for what sauna sweat actually drains — not what athletic sweat drains over hours.
When do I take it?
One scoop in 8-12oz of cold water, 15-30 minutes before your sauna session. Refill with plain water as needed during. One serving is calibrated for one 30-minute session at 180°F.
When does it ship?
All founders pre-orders ship mid-June 2026. You'll get tracking the moment your order leaves the warehouse.
What's in the formula?
1,000mg sodium, 400mg potassium, 100mg magnesium glycinate, 250mg vitamin C. Other: citric acid, natural strawberry lemonade flavor, stevia leaf extract. That's it. No sugar, no artificial colors, no proprietary blends.
Can I cancel my subscription anytime?
Yes — cancel, pause, or change cadence anytime from your account. Subscription saves you 15% per tub ($40.80 vs $48) and ships every 60 days, calibrated for ~4×/week sauna routine.
Is this safe if I'm on blood pressure medication?
1,000mg of sodium per serving is significant. If you're on blood pressure medication, have kidney disease, or are otherwise sodium-restricted, talk to your physician before using.
Where is it made?
Manufactured in an FDA-registered, cGMP-compliant facility in Long Island, NY. Every batch is third-party tested for heavy metals and ingredient identity. COA available on request.
