Understanding your immunity after 40
Immune health after 40 refers to your body's ability to maintain active defenses against external threats while adapting to the gradual decline of oestrogen and progesterone. During this transition, the body goes through complex biological adjustments that directly affect immune response and general vitality.
If you've noticed that you catch seasonal bugs more easily, or take longer to bounce back, know that this is completely normal. With perimenopause and menopause, declining female hormones weaken the gut barrier and disrupt the responsiveness of your immune cells.
Why hormonal shifts trigger fatigue and low immunity
The persistent fatigue experienced by many women in their 40s and 50s is not a lack of willpower, nor is it just a lack of sleep. It is deeply connected to endocrine changes. Oestrogen is a key regulator of inflammation and energy production at the heart of our cells.
When hormone levels decline, the body can enter a state of low-grade systemic inflammation, commonly called "inflammaging". This silent inflammation acts like a smouldering fire that consumes your cellular energy. Your mitochondria (the cells' energy factories) work slower. As a result, chronic fatigue sets in, and your immune system, occupied by this internal inflammation, becomes less effective at fighting external viruses.
How the six active ingredients of Immu'boost protect your body
To address this double challenge of fatigue and weakened immunity without stressing your body, nature offers exceptional resources. Immu'boost is formulated as a gentle alliance between traditional phytotherapy and mycotherapy. It combines six organic active ingredients that work in perfect synergy:
- Thyme: A natural friend of your respiratory tract, it gently purifies the body and clears the airways at the first sign of a chill.
- Echinacea: It wakes up your natural defenses by encouraging white blood cell production, vital for fighting off external infections.
- Acerola: A true powerhouse of natural, bioavailable Vitamin C, it boosts daily vitality and protects cells from ageing.
- Reishi: Surnommed the "mushroom of immortality", this premium adaptogen calms the nervous system, lowers cortisol spikes, and supports deep, restorative sleep.
- Maitake: It supports metabolic balance, helping to stabilize blood sugar and limit weight gain common after 40.
- Shiitake: Rich in immune-modulating beta-glucans, it strengthens cellular defenses while supporting cardiovascular health.
Targeted action of our ingredients on your immunity and vitality
Here is how each of these six actives specifically supports your body's needs during this transition. This dual action on immunity and energy helps you restore physical and mental balance.
| Active natural ingredient | Action on immunity | Action on vitality and menopause |
|---|---|---|
| Thyme | Purifies the respiratory tract and acts as a natural antibacterial shield. | Supports body detoxification and relieves mild metabolic overload. |
| Echinacea | Actively stimulates the production of white blood cells (lymphocytes and macrophages). | Helps the body recover faster after periods of fatigue or illness. |
| Acerola | Provides powerful antioxidants to protect immune cells from oxidative stress. | Delivers highly bioavailable Vitamin C to combat physical and mental fatigue. |
| Reishi | Modulates and regulates immune reactions to prevent inflammatory overload. | Calms stress, soothes the nervous system, and supports restorative sleep against night sweats. |
| Maitake | Activates deep defense cells (NK cells) for increased immune surveillance. | Supports sugar metabolism and helps regulate weight gain during menopause. |
| Shiitake | Strengthens the gut barrier and balances the microbiome, home to 70% of immunity. | Protects blood vessel health and supports circulation for heavy legs. |
Simple daily habits to preserve your energy
Alongside a targeted cure like Immu'boost, simple and gentle habits can make a huge difference in your daily wellbeing:
- Prioritize restful sleep: Avoid screens after 9pm and sleep in a cool room (around 18°C) to reduce night sweats.
- Eat anti-inflammatory and seasonal foods: Focus on green vegetables, antioxidant-rich berries, and healthy fats like olive oil or fatty fish.
- Practice gentle movement: If you are exhausted, avoid high-intensity sports that strain your adrenals. Prefer nature walks, yoga, or gentle pilates.
Pitfalls to avoid to stay in shape
Sometimes, in trying to do well, we make mistakes that drain our body even more. One common trap is using excess coffee or sugary drinks to mask fatigue. These stimulants trigger cortisol spikes that exhaust your adrenals and disrupt your sleep.
Also avoid cheap synthetic vitamins or overly aggressive immune boosters. The body of a woman over 40 needs gentleness and premium quality: always choose organic, bioavailable actives, completely free from phytoestrogens for total hormonal safety, and respectful of your biological rhythm.

Frequently asked questions
Why does immunity decline after 40 for women?
After 40, the drop in oestrogen during perimenopause triggers low-grade chronic inflammation, known as inflammaging. This hormonal shift disrupts the immune system's efficiency, making women more susceptible to fatigue, seasonal viruses, and slower recovery.
What are the key ingredients of Immu'boost?
Immu'boost combines six powerful organic actives: Thyme, Echinacea, Acerola (natural Vitamin C), and three adaptogenic medicinal mushrooms: Reishi, Maitake, and Shiitake. Together, they regulate the immune response, target inflammaging, and combat chronic fatigue.
Can I take Immu'boost during perimenopause?
Yes, Immu'boost is highly recommended during perimenopause. Its adaptogenic mushrooms help balance the nervous system, reduce cortisol spikes, and address the hormonal fatigue that commonly occurs during this transition.
How long does it take to feel the effects of adaptogenic mushrooms on energy?
Most women notice a lift in their energy levels and sleep quality within two to three weeks of daily use. For long-term immune support and hormonal balance, a consistent three-month course is recommended.
Does Immu'boost contain phytoestrogens?
No, Immu'boost is formulated without phytoestrogens. This makes it completely safe for women who have hormonal contraindications or a history of hormone-sensitive conditions and cannot use traditional phytoestrogen supplements.
