“I slept 9 hours a night but already woke up completely exhausted, with only one wish: for the day to end. When I talked to my doctor about it, he just replied that 'it was age' and that I had to live with it. Needless to say, I felt very alone... I tried Immu'Boost a bit by chance. And then, the click. I got my energy back and I finally feel like 'me' again.”

Free yourself from menopause symptoms.
Rediscover the daily comfort and energy you need to fully experience this new stage.
Hot Flashes
Those unpredictable waves of heat that invade your daily life and steal your serenity. A physical discomfort that weighs on your confidence and brutally interrupts your moments of calm.
Intense Fatigue
This feeling of heaviness that never leaves you, even after a 'good' night. Your body feels weighed down, and every gesture requires superhuman effort that eats away at your life reserve.
Sleep Disorders
The exhausting cycle of broken nights where rest slips away. Without restorative sleep, you lose the ability to regenerate your system at sunrise.
Mood Swings
These emotional rollercoasters that exhaust you as much as those around you. This feeling of no longer controlling your reactions to daily stress, creating permanent tension.
Brain Fog
When words escape you and concentration becomes blurred. This loss of cognitive clarity strips you of your usual intellectual agility, creating frustration and insecurity.
Fragile Immunity & Weight Gain
This metabolism that seems to run in slow motion and this body that no longer protects you as well. A vulnerability that sets in, changing your silhouette and your confidence.
Your body is capable of great things. It just needs the right support at the right time.
One formula = 6 ingredients
Ethically sourced active ingredients, cold-extracted and clinically dosed for immediate systemic efficacy.
Why your body resists… and how Immu'Boost re-teaches it.
From age 40, the drop in estrogen disrupts the cortisol-immunity axis. Your defense cells become less effective — not because you are fragile, but because your biology has changed. Here is what our specialists have discovered, and how the Immu'Boost formula addresses this precise mechanism.

Dr. Jean-Michel Morel
Phytotherapist Doctor
Women in menopause often have an immune system that over-reacts or under-reacts — never calibrated. The β-glucans from Reishi and Shiitake re-teach your defense cells to work with precision, without depleting your energy reserves.

Lucile Gélébart
Naturopath specialized in micronutrition
Synthetic vitamin C passes through the body very quickly. Acerola vitamin C is accompanied by natural co-factors — 'carriers' that keep it active 3 to 4 times longer in your cells. For an anti-fatigue formula, this difference is fundamental.
Pr. Francesco Rastrelli
Immunologist & Phytotherapy Researcher
Echinacea is the formula's sentinel: it strengthens the first-line barrier while the adaptogenic mushrooms work in depth. It's this synergy between immediate defense and deep re-education that makes Immu'Boost different from a standard supplement.

Everything you need to know about EyZa™
No, absolutely none. Unlike many supplements based on soy or sage, Immu'Boost's formula uses only adaptogenic mushroom extracts and plants with no estrogenic activity. It can be safely consumed, including by women with hormonal contraindications or a history of hormone-dependent cancers.
The first effects on energy and vitality are generally felt within 2 to 3 weeks. For complete and lasting results on immunity and hormonal balance, we recommend a course of at least 2 consecutive months.
Immu'Boost is a well-tolerated natural formula. However, if you are following a specific medical treatment, we recommend informing your doctor before starting any supplementation.
