My Story

"It all started with one big question: How could I restore my hormonal balance and therefore my health, without sacrificing my love of endurance sports?"

When the journey began

My journey into nutritherapy began in 2017, in my early thirties. At the time, I was living and working in Hong Kong, combining a demanding professional life with my love for mountain running, while struggling with severe hormonal imbalances and infertility. After years without a menstrual cycle, I was told that IVF was my only option.

But something in me refused to settle. I was searching for deeper meaning and real answers about my health. I believed there had to be another way. So I began studying nutritional and environmental approaches to hormonal health. What started as a personal quest became a professional calling.

"I believed there had to be another way."

Three years later, in 2020, I completed my nutritherapist certification — the same year I naturally conceived and gave birth to my first child. Today, I'm the mother of three, all naturally conceived and born. Something I once feared might never happen.

From personal insight… to professional support

Since my twenties, I've followed a mostly vegetarian diet, constantly exploring how to nourish my body while staying true to my values. My curiosity has led me to explore various dietary approaches, including a year on a ketogenic diet during my endurance sport years — giving me invaluable insight into the real-life challenges of adapting nutrition to support both performance and well-being.

This background, combined with scientific training and professional practice, shaped the core of my approach: science-based, personalized, flexible, and anchored in long-term thinking. I don't believe in rigid programs or shortcuts — but in understanding your body, supporting it wisely, and growing your confidence along the way.

Always curious about the "why" and the "how," I continue to deepen my knowledge through ongoing training in functional and adaptive nutrition.

I've had the pleasure of working with Claire to gradually increase my daily intake of protein, especially to reintroduce meat into my vegetarian diet, and the experience has been incredibly positive. Claire has been exceptionally attentive to my concerns, providing professional insights and clear, well-informed answers to all my questions.

Clara — Pilates Instructor Bangkok, Thailand

Claire helped me understand how to balance my diet through my menstrual cycle. After 6 months, I gained energy and strength. I saw an amazing evolution on my hormone balance and managed to manage my vegetarian diet. She has been available and helpful for each step of the process and very understanding. Her program is very detailed. She has an important scientific knowledge that made me very confident. I would not hesitate to use her services again in the future.

Sacha — Yoga Teacher Bangkok, Thailand

I had the pleasure of working with Claire across three sessions focused on my bulking goals. As a French expat living in Thailand and training in both weight training and Muay Thai, I needed guidance tailored to my lifestyle, activity level, and local diet. Claire quickly grasped my profile and objectives, and delivered clear, personalized, and actionable recommendations. I particularly appreciated her practical advice on supplements suited to my nutritional needs and budget. I would wholeheartedly recommend her services.
