Two ingredients. Both dosed in full.
No proprietary blends, no filler list. Every milligram is printed on the label.
800 MG PER SERVING
Clinoptilolite Zeolite
A natural volcanic mineral with a microscopic cage like structure, optimized and nano sized so more of it can trap positively charged heavy metals in the gut before they recirculate.*
- Heavy metal binding in the gut*
- Full 800 mg dose, no proprietary blends*
150 MG PER SERVING
Acacia (Gum Arabic) Fiber
A soluble prebiotic fiber that binds organic compounds and supports regular elimination, so what gets trapped actually leaves. Works alongside zeolite for dual action coverage.*
- Binds organic compounds*
- Prebiotic, supports good gut bacteria*
THE SCIENCE
Every gummy, backed by research.
Each mechanism below links to the published research behind the ingredient. No hand waving, no borrowed authority.
Sweat carries out only a fraction
The Blood, Urine and Sweat study tracked toxic elements across all three routes and found many are only partially eliminated through sweat. The rest leave through the gut.

Bile acids recirculate most of each cycle
Compounds packaged into bile reach the gut, where without something to bind them the majority are reabsorbed and sent back around.

Zeolite's cage like structure
Clinoptilolite is a natural volcanic mineral whose microporous structure preferentially binds positively charged heavy metals in the gut through ion exchange.

Doesn't deplete essential minerals
A long term human clinical study on clinoptilolite supplementation tracked blood mineral parameters and did not find depletion of essential minerals.

Acacia acts as a prebiotic
Gum arabic established prebiotic functionality in healthy volunteers, supporting beneficial gut bacteria and regular motility.

Not all binders are selective
Activated charcoal binds broadly and non selectively. Useful acutely, but it doesn't discriminate between what you want gone and the nutrients you'd keep.

Who this is for
You sauna 3+ times a week
Heat mobilizes stored compounds every session. Without a binder, most of them recirculate before your body can clear them.
You train hard and recover in the heat
Training six days a week and sauna after every session means your body is cycling compounds constantly. A pre sauna binder closes the loop.
Your stack is dialed, except this
Electrolytes, cold plunge, red light. You've optimized everything above the surface. This handles what's happening inside.
Meet the Pre Sauna Protocol.
Clinical dose binders. Zero sugar. One gummy.

THE FULL STACK
Everything you need for a cleaner sauna session.
The gummies do the binding. The kit handles everything around them: the protocol, the prep, and the recovery gear. Pick the bundle that fits how often you sauna.
CHOOSE YOUR BUNDLEThe Biohacker's Guide to Sauna Mastery
The full protocol: session timing, heat progression, when to bind, when to hydrate, and how to structure a week.
Detox Scraper
A body scraping tool for pre session skin prep. Stimulates circulation and exfoliates so you're sweating through clean skin from the start.
HeatCap
A sauna hat that shields your scalp and ears from direct heat, letting you stay in longer without the head pressure that cuts sessions short.
Cooling Briefs
Boxer briefs with a built in cooling pouch over the front panel. Keeps things cool where heat exposure hits hardest during long sessions.
Why do I need a binder for sauna at all?
Sweating clears some water soluble compounds through the skin. Most of what your body mobilizes during heat goes a different route, processed by the liver, packaged into bile, and released into the digestive tract. Bile acids are then recirculated back through the small intestine at a high rate per cycle (Ridlon et al. 2006). That's normal biology, not a malfunction.
A binder taken beforehand sits in the gut and gives some of that material something to attach to on the way through.
Why 30 minutes before, and not after?
A binder can only work on what's in the gut at the same time it is. Take it after and you've missed most of the window. Thirty minutes is enough for the gummies to break down and hydrate so the binders are in position before your session starts.
Running late? 15 minutes is better than nothing, and much better than after. Just don't take them mid session.
I already take other supplements. Will this interfere?
Space it out. Binders don't distinguish between what you want gone and the magnesium you paid for, so take Serana on its own, ideally 1 to 2 hours away from other supplements and away from meals. Since it's timed to your sauna session, this usually sorts itself out.
If you take prescription medication, talk to your doctor or pharmacist before adding any binder to your routine. Timing matters with some medications.
Will it back me up?
The acacia fiber is in there specifically so it doesn't. It's a soluble, fermentable fiber that supports normal motility and feeds beneficial gut bacteria (Calame et al. 2008), the opposite behavior from a binder taken alone. If you're prone to sluggish digestion, keep your water up on sauna days.
Is it vegan?
Yes, it's pectin based with no gelatin. For gluten and other allergen questions, reach out to our support team. We're finalizing full allergen documentation and would rather answer you precisely than guess.
How long does one jar last?
It maps to how often you sauna, not to a calendar month. Two gummies per session:
- 5+ sessions/week, about 6 weeks
- 3 to 4 sessions/week, about 2 months
- 1 to 2 sessions/week, about 4 months
Does this work with infrared? What about steam or a portable unit?
Yes to all of them. The timing is built around what your liver and gut are doing, not how the room gets hot. Traditional, infrared, steam, barrel, portable tent. If you're sweating meaningfully for 15+ minutes, the window is the same. Two gummies, 30 minutes before you get in.
Do I need this if I only sauna once or twice a week?
It's less essential than for someone going five times a week, but the logic doesn't change with frequency. The same thing happens in a single session as in twenty, just less often. If your sessions are irregular right now, a single jar is the sensible way in.
Can I take them on days I'm not using the sauna?
You can. The zeolite and acacia fiber don't stop working on rest days. But the formula and timing were built around the acute window that heat creates, so that's where the value concentrates. Most people run it on sauna days only, and a jar lasts proportionally longer.
Is this only for men?
The brand is built for and marketed to men, but nothing in the formula is sex specific. Two honest caveats: the included Sauna Guide is written for a male audience, and as with any supplement, if you're pregnant or nursing, check with your doctor first.
Will this help me lose weight?
No, and we're not going to pretend otherwise. This isn't a weight loss product and we don't make weight loss claims for it. The scale change you see after a sauna session is water, and it comes back when you rehydrate, which you should.
If weight is your main reason for buying, this isn't the product for you.
What if I don't feel anything?
Fair question. This isn't a stimulant. There's no rush or tingle. It works in your gut while you're sitting in the heat thinking about something else.
What people tend to report is a difference in the hours after a session rather than during it. Less of that flattened, drained feeling later in the evening, and more regular digestion within the first week or two. If you run it for a full jar and it's done nothing for you, use the guarantee. Results vary.
Can I change how often it ships?
Yes. You set the interval, and you can change it, skip a shipment, or pause any time from your account. No email required.
