Hot Flash & Night Sweat Support In One
Sage Extract (Salvia officinalis)
Targets the brain's temperature alarm, the hypothalamic thermostat, directly
Studied for reducing both the frequency and intensity of hot flashes
Standardized 10:1 extract, the concentrated form used in clinical research
Hormone-free, no estrogen added or mimicked
Well-tolerated for daily, long-term use
Key Ingredients
Sage Extract 400 mg (10:1, equal to 4,000 mg raw sage leaf)
The exact dose used in the Bommer 2011 randomized clinical trial
The trial measured a 64% reduction in hot flash frequency at week 8
Works by restoring GABAergic inhibition in the temperature-control center
Most retail supplements contain just 25 to 50 mg, a fraction of the studied dose
Soy Isoflavones 50 mg (standardized to ≥40%)
Supports the body's own estrogen-signaling pathways without adding hormones
Studied for menopausal symptom support at this dose range
Saffron Extract 30 mg (standardized to 3% safranal)
For the 2 AM anxiety and irritability that ride along with the flashes
Supports calmer mood and steadier sleep
Maca 300 mg, plus Vitamins D3, K2 (MK-7) and E
Maca for daytime energy and stamina
D3 and K2 to support bone density during the menopausal transition
E for cardiovascular support
Every active is listed at its exact milligram dose. No proprietary blends, nothing hidden.
How to use
Take 2 capsules daily, preferably with a meal. Each bottle contains 60 capsules, a 30-day supply. Thermozen works on the cause of hot flashes, not the surface heat. When estrogen declines, the brain's temperature center starts firing false alarms over tiny shifts. The clinical 400mg sage dose helps restore the brake on that alarm, so the flashes quiet at the source instead of being chased with fans and cooling pads.
How Long Before I See Results?
The clinical trial measured its main result at week 8. Most women report the first change in their sleep around week 4, as the active compounds reach steady levels and the temperature alarm begins to settle.
The full reset runs across 90 days, which is why the 3-bottle kit is the most popular option. This is not a product that wears off by morning. It rebuilds over the window the research actually studied, and the gains tend to hold with continued daily use.
90-Day Money-Back Guarantee
The clinical trial measured its full result between week 8 and 12, so we give you the full 90 days. Take Thermozen every day for 90 days. If your nights haven't changed and you don't feel the difference, send back even the empty bottles for a full refund. No return required. The risk is entirely ours.
Is It Safe?
Thermozen is made in the USA in a GMP-certified facility and contains no hormones and no prescription compounds. It's generally well tolerated. As with any supplement, talk to your doctor before starting, especially if you take prescription medications or have a hormone-sensitive condition.
3RD PARTY & CLINICALLY TESTED
Your 90-Day Thermostat Reset
This is not a cooling product that wears off by morning. Over 90 days it rebuilds the brake on your brain's temperature alarm, so the relief holds instead of fading.
🌡️
Calms The Sudden Flashes
The 400mg sage dose restores the GABAergic brake on the alarm. Fewer flashes, and the ones that come hit softer."
📈
Holds Steady Under Triggers
A warm room, a glass of wine, a stressful call. The triggers stop tripping the full alarm as the thermoneutral zone widens back.
⚙️
Rebuilds The Brake Over 90 Days
This is the part 30-day supplements miss. The trial measured its 64% reduction at week 8. The full reset takes the 90-day window.

Protects The Nights Most Of All
Night sweats wreck sleep harder than daytime flashes wreck the day. Steady overnight temperature is where most women feel it first."
Your Brain's Thermostat Is Misfiring. That's Why Nothing Has Worked.
Hot flashes are not caused by your body overheating. They happen because your brain's temperature control center, the hypothalamus, loses its estrogen signal and goes into alarm mode. When estrogen declines, your thermoneutral zone collapses from a 1.3C comfort range down to 0.2C. Now the smallest trigger trips the full alarm. A warm room. A sip of coffee. A moment of stress. Your body slams on the heat-dump: the flush, the sweat, the racing heart.
This is why fans do not stop it. Why cooling pads do not stop it. Why most supplements do not stop it. They all treat the heat. Thermozen targets the signal that fires the alarm.
