A Word from Sylvie

This project was born from my own journey, from my search for a solution to chronic stress and hormonal imbalances . I am, in fact, my first client; I wanted a world that would take care of me holistically, from the inside out, and that would support me with gentleness, awareness, and authenticity.

Chronic stress: a universal problem

Stress is a normal biological response of the body, but when it becomes prolonged , it can lead to consequences for physical and mental health.

📊 A statistical reality

  • 59% of French people report being stressed in 2025, an increase compared to previous years, with particularly high levels among women and young adults. (Ramsaysante Foundation)
  • 61% of working people experience regular stress at work , at least once a week. adp
  • 12.5% ​​of adults experience significant anxiety , with a prevalence three times higher in women than in men. beh.santepubliquefrance
  • According to surveys, nearly 9 out of 10 French people have experienced stress at some point in their lives , and stress has been identified as a frequent disruptor of daily life. (Laboratoire Lescuyer)

🧬 Concrete consequences for health

Science shows that prolonged exposure to chronic stress is associated with an increased risk of developing or worsening:

  • cardiovascular diseases (hypertension, heart attack, stroke),
  • metabolic disorders (diabetes),
  • immune system disorders ,
  • anxiety and depressive disorders ,
  • systemic inflammation ,
  • Cognitive impairment linked to excess cortisol. pmc.ncbi.nlm.nih.gov

⚠️ A global impact, disproportionate among women

Women generally report higher levels of perceived stress and have significantly higher prevalences of anxiety disorders than men, highlighting the need for specific prevention and support approaches. beh.santepubliquefrance

This finding shows that chronic stress affects a large part of the population, and that a preventive approach is more important than ever.

Le stress chronique est un problème universel

Le stress est une réponse biologique normale du corps, mais lorsqu’il devient durable, il peut entraîner des conséquences sur la santé physique et mentale.

📊 Une réalité statistique

  • 59 % des Français déclarent être stressés en 2025, une augmentation par rapport aux années précédentes, avec des niveaux particulièrement élevés chez les femmes et les jeunes adultes. fondation-ramsaysante
  • 61 % des actifs ressentent un stress régulier au travail, au moins une fois par semaine. adp
  • 12,5 % des adultes présentent un état anxieux notable, avec une prévalence trois fois plus élevée chez les femmes que chez les hommes. beh.santepubliquefrance
  • Selon des sondages, près de 9 Français sur 10 ont ressenti du stress au cours de leur vie, et le stress a été identifié comme un perturbateur fréquent de la vie quotidienne. laboratoire-lescuyer

Des études et revues scientifiques montrent que le stress peut :

✔️ Stress et peau

  • provoquer ou aggraver des affections cutanées courantes comme l’acné, l’eczéma, le psoriasis ou l’urticaire, en augmentant l’inflammation et les réactions immunitaires de la peau.
  • altérer la barrière cutanée, ce qui rend la peau plus sèche, réactive ou sensible aux agressions. stressmeasurement.org

✔️ Stress et cheveux

  • Il est associé à des formes de perte de cheveux comme l’effluvium télogène, où un grand nombre de cheveux passent en phase de chute. aad.org
  • Le stress peut aussi jouer un rôle dans certaines formes d’alopécie (perte de cheveux d’origine auto‑immune).
  • Des recherches indiquent même que les niveaux de cortisol dans les cheveux, mesurés comme un marqueur de stress chroniqué, changent chez les femmes enceintes selon leur exposition au stress, montrant un lien entre stress et réponses physiologiques. pubmed.ncbi.nlm.nih.gov

✔️ Stress chronique, grossesse et santé immunitaire / peau

  • Une étude publiée dans Nature suggère que le stress maternel pendant la grossesse, via une élévation du cortisol, peut altérer le système immunitaire du fœtus et accroître le risque d’eczéma chez l’enfant. presse.inserm.fr
  • D’autres travaux montrent que la mesure du cortisol (marqueur de stress) dans les cheveux est un indicateur de stress chez les femmes enceintes, reflétant une réponse physiologique prolongée. sciencedirect.com

✔️ Stress et immunité

Le fonctionnement du système immunitaire peut aussi être affecté :

  • Le stress chronique altère la régulation immunitaire et peut contribuer à une immunosuppression, une réponse inflammatoire permanente ou un déséquilibre des cytokines, ce qui affaiblit la capacité de l’organisme à répondre aux infections et aux agressions. mdpi.com
  • Le stress peut affecter le microbiote intestinal, perturbant la production de certaines molécules essentielles à la barrière digestive et à la régulation immunitaire.
  • Par ailleurs, des troubles digestifs comme ballonnements, reflux ou douleurs abdominales peuvent être liés à une activation prolongée de l’axe du stress.

🧬 Conséquences concrètes sur la santé

La science montre que l’exposition prolongée au stress chronique est associée à un risque accru de développer ou d’aggraver :

  • maladies cardiovasculaires (hypertension, infarctus, AVC),
  • troubles métaboliques (diabète),
  • dérèglements immunitaires,
  • troubles anxieux et dépressifs,
  • inflammation systémique,
  • troubles cognitifs liés à un excès de cortisol. pmc.ncbi.nlm.nih.gov

⚠️ Un impact global, disproportionné chez les femmes

Les femmes rapportent généralement des niveaux de stress perçu plus élevés et présentent des prévalences de troubles anxieux significativement supérieures à celles des hommes ce qui met en lumière la nécessité d’approches de prévention et de soutien spécifiques. beh.santepubliquefrance

Ce constat montre que le stress chronique affecte une large partie de la population, et qu’une approche préventive est plus importante que jamais.

A new generation of products that regulate without being abrupt.

We don't fight stress, we help the body adapt to it. Our approach is based on the synergy between science, medicinal plants, and targeted micronutrients.

✧ Why are adaptogens at the heart of our formulas?

Because they have a unique ability:

👉 Reduce the negative effects of stress, without blocking vital functions.

Adaptogenic plants strengthen the body's resilience while respecting its biological intelligence. They don't silence warning signals; they help the body respond to them in a more stable and fluid way.

Ashwagandha, Rhodiola, Shatavari, Reishi, Maca, Schisandra…

Each plant is chosen for its ability to support a specific function (nervous system, hormones, energy, mood…).

✧ A different approach to classic "boosters"

Most anti-fatigue products work by stimulating , often at the cost of a rebound effect or long-term exhaustion .

Our adaptogens do the opposite:

✅ They regulate ,
✅ They calm without making you sleepy ,
✅ They provide support without over-activating.

It is a sustainable, preventative approach, without addiction.

✧ Nutrients to strengthen the terrain

In addition, we have selected highly bioavailable active ingredients to enhance the effects of the plants:

  • Magnesium (in bioavailable forms) → nerve and muscle regulation
  • Vitamin D3 → immune balance, mood, energy
  • Zinc, B6, Iron → hormonal support, metabolism, mental clarity
  • and many more...

✧ The Revnchi Promise

We are committed to offering you carefully crafted formulas. Traceable ingredients, dosed for their real effectiveness, without any unnecessary additives, excesses, or "trendy" ingredients just for aesthetic purposes.

We dream of a world where taking care of oneself is no longer a luxury, nor an emergency.

We want to talk about stress before it causes damage, about mental load before it explodes, about hormonal fatigue before it becomes the norm. And above all, we want to do it together.

It's a community project on a human scale. A movement that begins in a treatment... but extends to talking circles, shared rituals, interventions in companies, sensory retreats, moments to finally breathe.

We can already picture our bottles in the bags of busy women, exhausted mothers, young people searching for meaning, men who want to understand their bodies, and team leaders tired of running around. We envision Revnchi spaces in schools, coworking spaces, festivals, businesses, and villages. We imagine a future where we no longer wait until we're completely worn out to listen to what our bodies have been whispering for months.

Revnchi is that energy, lucid but full of hope , rooted but turned towards tomorrow.

And this is just the beginning.

Sylvie is the founder of Revnchi ,

A French brand of food supplements founded with the aim of addressing invisible imbalances before they become visible.

At 31, she received a brutal diagnosis: stress-related cardiomyopathy , also known as broken heart syndrome .

This is a warning sign of a body that has been overloaded for years, with chronic stress, nervous fatigue, hormonal instability, and severe anemia that has never been resolved despite conventional approaches.

Faced with the lack of a lasting response, she decides to understand what happens in the body before the symptoms appear, where it all begins.

She trained in nutrition, micronutrition, herbal medicine, and the biology of stress . She became interested in the role of the nervous system, the adrenal glands, hormonal cycles, and their interactions. Very quickly, she realized one thing: imbalances don't begin the day we feel them. They take root in what we can't see: inflammation, latent deficiencies, commonplace hormonal imbalances, prolonged stress...

Revnchi was born from this realization.

Designed to support women (and soon all profiles) in their fundamental balance, by working on the real causes not just the symptoms .

Thanks to a precise selection of adaptogenic actives, functional plants and targeted nutrients, Revnchi offers a new way to support the body naturally, sustainably and intelligently.

Quality and Safety

The quality and safety of our products are our top priorities. We collaborate with a rigorously selected dietary supplement laboratory that adheres to the strictest European standards. Every stage of manufacturing is ISO, GMP, and HACCP certified, guaranteeing safe, pure, and reliable products.

No compromises are made on the quality of the ingredients or the manufacturing process, ensuring that every supplement we offer reflects our high standards and commitment to your well-being.

Let us never forget that...

Taking care of oneself is not a trend but a necessity, especially for women whose bodies are intimately linked to cycles, hormones and emotional burdens.
