The science behind ZÄNA
Your gut and your brain never stop talking
90% of serotonin is produced in the gut, and the vagus nerve sends signals to your brain 24 hours a day. When that conversation breaks down, fatigue, brain fog and inflammation appear. ZÄNA repairs it at the root.
Mental clarity
A balanced microbiome produces the neurotransmitters that sustain your focus and your mood.
Sustained energy
No glucose spikes or crashes: steady fuel from morning to night.
Less inflammation
We switch off the low-grade inflammation behind chronic tiredness.

Testimonials
What our community says
★★★★★
Thank you Dra. Jackie for your help and your constant support through the ZÄNA program. After having my baby, food went beyond looking good: it is about feeling good, and of course having enough energy to be a mother 100% of the time, a homemaker, a business owner and a wife.
★★★★★
Before joining the program, the effects of cancer treatment —chemotherapy and radiotherapy— had left me with chronic fatigue, weakness, poor sleep quality, night sweats, hot flushes, neuropathy, low energy and irritability. I slept 10 hours and still needed a nap to function. What I value most is that Dra. Jacky listened to and respected my body's needs at every moment. I never felt judged or compared with others; her support was always personalised, understanding and full of encouragement. Today I no longer have neuropathy, fatigue or night sweats. The hot flushes are less frequent and less intense. I sleep better: I now rest 8 hours without naps and keep my energy through the day. My muscle tone and strength have improved; I also noticed less swelling and cellulite. Even though I was told it was not the time to lose weight, I was able to lose 12 pounds of fat and inflammation in a healthy, sustainable way. The changes have gone beyond the physical: my mind is clearer, I think more sharply and my mood has improved noticeably. Above all, this program gave me back the hope that my body can keep healing and recover completely.

"I want to express my most sincere thanks to Dra. Jacky for her invaluable support and guidance through her eating plan. Her approach not only transformed my relationship with food, it also helped me understand and manage my cravings in a healthy way.
Over the last ten months I have had the satisfaction of losing around 38 pounds, which has been a great personal achievement. I have not only noticed changes in my weight: my inflammation problems have disappeared, and my energy has come back in a surprising way.
On top of that, my blood test results are the best I have ever had, something that makes me immensely happy at 58. Thank you, Dra. Jacky, for guiding me on this path towards a healthier, fuller life. Your dedication and knowledge have made a significant difference to my wellbeing.

I never imagined that in four months I could feel this well, thanks to Dra. Jackie. Her professionalism was obvious, but what I value most was her empathy and patience. She explained every step of the program clearly and always answered my questions, guiding me towards healthy food choices. I lost 50 pounds and much of the inflammation and, more importantly, I recovered my energy, my wellbeing and my confidence.
