There's A Credit Card Of Microplastic In Your Body Right Now
Sauna is one of the only elimination pathways your body has for compounds it can't break down. Here's the protocol most people get wrong - and what to do instead.

📊 Cited research: Leslie et al. (2022) Environment International — first detection of microplastics in human blood. Genuis et al. (2011) Archives of Environmental Contamination and Toxicology — heavy metal excretion via induced sweating.
Problem #1
Microplastics Don't Leave On Their Own
Your blood, lungs, and brain tissue all show measurable microplastic concentrations. Your liver doesn't have an enzyme that breaks polyethylene down.
Your blood, lungs, and brain tissue all show measurable microplastic concentrations. Your liver doesn't have an enzyme that breaks polyethylene down.
The 2022 Leslie study published in Environment International found microplastics in 17 of 22 human blood samples — at concentrations equivalent to the weight of a credit card per year of exposure. Follow-up studies have detected microplastics in placental tissue, lung tissue, and post-mortem brain samples.
Your body has three primary elimination pathways: urine, stool, and sweat. Microplastics are largely insoluble in water - so urine doesn't carry them efficiently. Sweat is one of the only ways out.
In your blood
17 of 22 samples in the 2022 Leslie study. Average: 1.6 µg/mL.
In your brain
Detected in post-mortem brain tissue (UNM study, 2024).
In your lungs
Found in 11 of 13 lung samples (Hull York Medical School, 2022).
Problem #2
Sauna Is The Most Accessible Elimination Pathway You Have
Induced sweating is one of the few mechanisms shown to mobilize fat-stored compounds.
The 2011 Genuis study published in Archives of Environmental Contamination and Toxicology measured arsenic, cadmium, lead, and mercury concentrations in blood, urine, and sweat from 20 subjects. Many toxic elements appeared at higher concentrations in sweat than in urine. Translation: your body can dump compounds through sweat that it can't efficiently push through the kidneys.
This is why every longevity researcher you've heard of — Rhonda Patrick, Søberg, Attia — recommends consistent sauna use. The Finnish 20-year cohort study found 4–7 sauna sessions per week reduced all-cause mortality by 40%.
But here's where most people lose the protocol.
Problem #3
Plain Water Sabotages The Protocol
A 30-minute sauna session at 180°F drains a liter of fluid AND 1,000 mg of sodium - the equivalent of a half marathon, except you sit still while it happens.
If you replace that fluid with plain water, you dilute your blood sodium further. Result: dizziness on standing, cramping that night, the "hungover" feeling the next morning, and the post-sauna crash that makes you skip tomorrow's session.
The protocol only works if you stay consistent. Consistency dies when you feel terrible afterward.
Dilutes blood sodium
Plain water lowers what's already low.
Triggers cramping
Magnesium and potassium loss + dehydration.
Kills consistency
Post-sauna crash → you skip the next session.

Common questions
Questions? We Have Answers
Does sauna actually remove microplastics?
Direct human trials measuring microplastic excretion in sweat are still emerging — we won't pretend otherwise. What's well-established: sweat carries heavy metals (Genuis 2011), persistent organic pollutants, and BPA at concentrations often higher than urine. Microplastics behave similarly in fat tissue. We're presenting the mechanism honestly, not making clinical cure claims.
How is this different from LMNT?
Same sodium (1,000mg). But we run 2× the potassium (400mg vs 200mg), 1.67× the magnesium (100mg vs 60mg), and add 250mg of Vitamin C that LMNT doesn't include. The ratios are calibrated for what sauna sweat actually drains — not athletic sweat over hours.
When do I take it?
Mix one scoop in 8-12 oz of cold water, 15-30 minutes before your sauna session. Refill with plain water as needed after. 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 it (full ingredient list)?
Sodium 1,000mg, potassium 400mg, magnesium glycinate 100mg, vitamin C 250mg. Other: citric acid, natural strawberry lemonade flavor, organic stevia leaf extract. That's it.
Is the subscription locked in?
No. 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.
