The axle microbiota–cortisol

Your gut microbiota and stress response system are connected through the gut-brain axis. When this axis becomes unbalanced, cortisol levels are chronically elevated. Cortisol Calm acts directly on this connection.

90%

The microbiota produces over 90% of the body's serotonin—the key neurotransmitter in mood regulation

The selected strains modulate the activity of the HPA axis, the central stress response system

Adaptogens complement the microbiota's regulating action on cortisol

The effect is systemic and progressive, not symptomatic—it acts on the cause, not the consequence

Ingredient system

6 active ingredients

Each ingredient selected for its clinical evidence and synergy with the microbiota. Completely open and transparent formula.

KSM-66® is the ashwagandha root extract with the highest concentration of active withanolides. It acts directly on the hypothalamic-pituitary-adrenal (HPA) axis, the central stress response system: it modulates cortisol production rather than suppressing it. Its effect is regulatory, not sedative. It reduces chronic overactivation of the stress system without causing dullness or dependence.

Clinical evidence

Randomized, double-blind study (Chandrasekhar et al., 2012, Indian Journal of Psychological Medicine) in 64 adults with chronic stress: 27.9% reduction in serum cortisol levels at 8 weeks, with significant improvement in perceived stress scale (PSS) and sleep quality (PSQI).

Your evolution

What you can expect

15 days
First signs of change
Your microbiota is starting to adapt. The strains colonize the gut and begin to modulate serotonin production. You may notice a deeper night's rest and less accumulated tension at the end of the day.
30 days
The axle is being recalibrated.
The HPA axis begins to regulate more efficiently. The stress response balances: less reactivity, better digestion, and a general feeling of greater emotional stability.
60 days
Consistent results
Cortisol levels stabilize in a sustained manner. Improved mental clarity, more consistent energy throughout the day, and digestive comfort that becomes your new normal.
90 days
New balance
Your microbiota has reached a new state of balance. Cortisol patterns are normalized. The effect is systemic: better sleep, better digestion, better stress response, all connected.
How to take it

Two capsules every morning, on an empty stomach or with breakfast. Daily consistency is the most important thing. Designed for optimal absorption in the early hours of the day.

Frequently asked questions

Everything you need to know

Cortisol Calm takes effect gradually; many users feel a greater sense of calm and relaxation from the very first doses, especially noting it in a high quality of sleep and reduction of mental noise before bed. However, to establish the structural benefits of Ashwagandha KSM-66® on systemic cortisol levels and general psycho-emotional well-being, we recommend continuous daily use for at least 2 to 4 weeks.
