BACKED BY SCIENCE.
3 Layers. 1 Cascade. Every Symptom Connected.
Every other supplement targets 1 layer. At 1/8 the dose. That's why nothing has worked. Thermozen targets all 3 at clinical doses.
Calm The Brain Alarm
Your hypothalamus fires a false alarm. That's the flash.
Sage 400mg shuts it off. 64% fewer hot flashes by week 8.
Most supplements use 50mg. We use 8x more.
Widen The Temperature Buffer
Your body's temperature tolerance collapsed from 4°C to 1°C.
That's why tiny warmth triggers a full heat dump.
Soy Isoflavones 50mg widen it back.
Backed by 16 trials. 1,710 women.
Quiet The Cortisol Amplifier
Cortisol turns every flash into panic. Racing heart. 2 AM dread.
Every other supplement ignores this layer.
Saffron 30mg — 33% less anxiety.
Maca 300mg — mood, energy, resilience.
The Version Of You That Sleeps Through The Night
3 layers calm. The cascade stops.
Cool nights. Stable mood. Energy past 2 PM.
You. Again.

What is Thermozen?
Thermozen is the 90-Day Menopause Reset Protocol — 7 clinical-dose ingredients that calm all three layers of the hot flash cascade. It addresses hot flashes, night sweats, mood swings, and sleeplessness at the source: the misfiring thermostat in your brain. Two capsules daily. Non-hormonal. No prescription needed.
Is Thermozen safe?
Yes. All 7 ingredients have been studied in clinical trials lasting 8-16 weeks with strong safety profiles. Thermozen is manufactured in a GMP + BRC + HACCP certified facility in the USA. It contains no hormones, no stimulants, no sedatives, and no synthetic fillers. Consult your healthcare provider before combining with prescription medications.
How to use
Take 2 capsules daily with food. Morning or evening — whichever fits your routine. Consistency matters more than timing. The protocol runs 90 days. Most women notice calmer nights within the first week. The clinical milestone is week 8.
Quality & Safety
Manufactured in an FDA-registered, GMP + BRC + HACCP certified facility.
Every batch is third-party tested for purity and potency. Vegetarian capsules. Contains soy (allergen disclosure).
All doses match published clinical research — verifiable on the label.
Can Thermozen be used long term?
Yes. Many women continue beyond the initial 90-day protocol. All ingredients have established safety profiles in published clinical research. The 90-day protocol is the minimum recommended duration because the soy isoflavones reach half-maximum benefit at week 13.4 (Li 2015).

Finally Sleep Through The Night. Dry. Calm. Every Night.
Every Night You Wait Is Another Night The Cascade Runs Unchecked.
The 90-day protocol doesn't start the day you think about it. It starts the day you take the first capsule.
Night 3: the first calmer night. Week 4: hot flash frequency drops. First full dry night for most women.
Week 8: 64% fewer hot flashes. Sleeping through. Mood leveling out. Day 90: the cascade quiet. Cool days. Dry nights. You again.
None of these start until Night 1 does.
And if it doesn't work — every dollar back. 90-day guarantee. No returns required.
Questions Women Ask Before Ordering
I've tried supplements before, they didn't work. Why different?
Most supplements include the right ingredient names at 12–25% of the clinically studied dose. They look correct on the label but cannot work at those amounts. Thermozen uses Sage Extract at the full 400mg used in the randomized controlled trial that produced the results. If what you tried before was underdosed, it wasn't a failure of your body. It was a failure of the formula.
Will this interact with my medications?
Thermozen contains soy isoflavones which may affect thyroid medication absorption when taken at the same time. If you take thyroid medication, consult your doctor first. If cleared, take Thermozen at a separate time of day from your thyroid medication. For other conditions, we always recommend checking with your doctor before starting any new supplement.
When can I experience results?
Most women notice the first shift between weeks 3–4. night sweats begin to space out, falling back asleep gets easier. By week 8, most report significantly fewer flashes. The full recalibration takes 90 days. That's why we guarantee the full protocol window, not just 30 days. Stopping at week 4 is stopping before the protocol reaches peak results.
Does ThermoZen have any side effects?
Thermozen contains no stimulants, no sedatives, and no hormones. The most commonly reported experience is no side effects at all. A small number of women report mild digestive adjustment in the first few days, which typically resolves. If you have a soy allergy or intolerance, Thermozen is not the right fit — it contains soy isoflavones.
Does it contain gluten, soy, peanuts, dairy, shellfish?
Thermozen contains soy isoflavones (50mg, standardized 40%) as one of its three active layers. It does not contain gluten, peanuts, dairy, or shellfish. If you have a soy intolerance or sensitivity, Thermozen is not the right fit — we wouldn't want you to order it.
Can I take it on a vegan / keto / paleo / kosher diet?
Thermozen capsules are vegetarian. The formula contains no meat, no gelatin, no dairy, and no gluten. It is suitable for vegan, ketogenic, and paleo diets. For kosher certification, please contact us directly at hello@vonolabs.com.
Does ThermoZen interact with thyroid medications?
Yes — this is important. Thermozen contains soy isoflavones which may affect thyroid medication absorption when taken simultaneously. If you take thyroid medication, consult your doctor before starting. If cleared to proceed, take Thermozen at a separate time of day from your thyroid medication.
Does ThermoZen contain caffeine or stimulants?
No. Thermozen contains no caffeine, no stimulants, and no sedatives of any kind. It works by supporting the hypothalamic thermostat signal through plant-based ingredients only — not by stimulating or suppressing your system.
