Hello, I’'m Claire
French nutritherapist based in Bangkok, offering integrative, functional and adaptive nutrition guidance.
Whether you're preparing for a sports event, transitioning to a plant-based diet, navigating a health challenge, or simply trying to reconnect with your body’s signals, you're in the right place.
Nutritional Therapy
Turning nutrition science into everyday support
clear, practical and adapted to your unique journey
Ready to reconnect with your health, on your own terms ?
Tell me a little about yourself, and let’s find the right program for you
Ready to start your journey?
Tell me a little about yourself, and let’s find the right program for you

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 ?




My method blends nutritional science with a personalized, realistic, and positive approach that respects your current lifestyle and long-term goals.
I believe that sustainable health is both evidence-based and deeply personal. When we align your nutrition with your unique needs, meaningful transformation becomes possible.
Having navigated my own health challenges, I understand what it means to feel stuck or uncertain and how powerful it is to find clarity, naturally and sustainably.
I offer both in-person sessions in Bangkok and online consultations, wherever you are.
There's no magic plan, just the right support, at the right time, for the right person.
That question led to a complete transformation of my lifestyle, mindset and career. And it continues to guide the spirit I bring to every consultation.

Simplifying nutrition
practical, science-based, adapted to your life
A personalized and evolving approach
Every journey is unique, and so is my guidance
Whether you're training, trying to conceive, or seeking balance, I take the time to understand your needs and goals. During a one-shot or a long-term follow-up, we'll shape a nutritional strategy that fits your reality, and evolves with you.


A supportive space, at your own rhythm
Trusted supplementation, integrated thoughtfully




Step by step, with care and clarity
Whether you need a focused session or ongoing support, I’ll meet you where you are, with respect for your pace. My follow-up options give you time to integrate, reflect, and grow, without rush but with progress and attention to what matters most.
Only when it makes sense, and with what I trust
When relevant, I include targeted supplementation in your protocol, always explained and contextualized. I offer precise recommendations using only brands I personally trust for their transparency and quality standards.
Functional, flexible, and always grounded in your reality

“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. Her deep knowledge of nutrition, combined with her constant availability and genuine dedication to helping me reach my goals, has made this process so much easier and more enjoyable. I’m truly grateful for her support and expertise.”
