Nutrition by Stella

Functional nutrition for women looking for better answers.

Hi, I'm Marlène Stella, functional nutritionist.

I support women with chronic symptoms, autoimmune conditions and "normal" test results to find what's really driving their health issues, with personalised nutrition and lifestyle support.

Based in France. Worldwide online.

You're doing everything right. Your body still disagrees.

If you have a diagnosis, a collection of unexplained symptoms, if everyday feels harder than it should… Or if you simply wants to act in prevention and optimise your health, there is a place for you here.

This work comes from lived experience.

For most of my life, I lived with symptoms no one could explain. Digestive issues since childhood. Daily chronic pain. Then burnouts in the media industry.

In 2022, I was diagnosed with Multiple Sclerosis. I was offered a plan to medicate, absolutely no hope, and not a single word about nutrition. I was just told to live with it and accept my fate. I didn't listen..!

I read everything I could about the gut, the immune system, inflammation. And as I couldn’t find anyone to help me the way I needed, I decided to go back to school and become the practitioner I couldn’t find.

Today, I'm in remission and in the best health of my life. I created this practice because I was tired of seeing women dismissed, rushed, and told they are "fine" when they are in pain. As a Functional Nutritionist, I now offer the kind of care I wish I received from the start.

I work alongside conventional medicine, not against it.

I bring the time, the functional lens, the deeper questions and the nutrition and lifestyle support a short medical appointment doesn't have time to offer you.

  • "Stella has been working with me for six months, and I feel a real difference. She taught me to listen to my body, to understand signals I was unaware of, and to take care of myself with more awareness. The real difference is her attention and genuine kindness. You feel supported and understood, and that changes everything. Thank you!✨ I highly recommend her!"

  • First of all, Stella's approach was excellent. She took the time to listen to and understand my difficulties and goals. Since I made changes to my diet (changes that were very easy to implement), my digestion has improved, and I can once again enjoy lovely walks without muscle pain. Thank you."

  • "If you are looking for someone who will listen not just to your symptoms, but to how you really feel, to your goals… someone from whom the term "personalized care" isn't just a marketing term… Then contact Stella today!"

  • "Stella is professional, attentive, gentle and always gives excellent advice. Thanks to her support, my health markers have significantly improved. I trust her completely and I recommend without hesitation!"

  • "My blood sugar is now stable, I have lost weight, I'm no longer bloated and I feel much better! I recommend AND I continue to work with Stella."

  • "Stella has great knowledge and understanding of the relationship between our habits and the body, so I promise you'll learn a lot! I loved working with her and I'm thankful for all we've achieved together. I recommend 100%!!!"

  • "I highly recommend Stella's nutrition workshop. It was very informative and gave me new perspectives on how and when to eat certain foods to help reduce bloating and avoid spikes in blood sugar. I left with practical knowledge that I can apply in my daily life. Looking forward to work with Marlene on one to one!"

  • "I joined one of Stella's workshop and I recommend it from the bottom of my heart! She shared a lot of knowledge about blood sugar and useful tips for composing meals! (I used it straight away for my lunch) She created a cozy gentle space, I felt very welcome to be there."
