The Power We Hold

What if your body was never broken...and every symptom was proof of an untapped power?

The Power We Hold reveals a radical truth: your body is responding intelligently to a world that was never built for women's wellbeing - and it’s time to stop blaming yourself for it.

Weaving together science, history and ancient wisdom, Isabella offers a practical path out of survival and into real, tangible healing.

"This book is dangerous – in the best way possible...Every woman who’s ever been dismissed, disbelieved, or gaslit by medicine needs this book like oxygen."

Dr. Jolene Brighten, FABNE, MSCP, author of Is This Normal?

From 50-30 day cycles and no more PCOS

When I first came to Isabella, I had PCOS, high cortisol, gut issues, in chronic flight/flight mode, grieving my best friend's death, my dad had a heart attack and I couldn’t process what was going on. With ThetaSomatics™ I've gone from 50-30 day cycles, reduced my PMS, fixed my gut issues, processed my best friend's death and I wake up feeling so thankful to be alive. My stress levels are better than they ever had before, I can cry again, I'm feeling much more confident in dating and I'm finally expressing myself authentically and pursuing my dream career. - Sarah, USA

Cured my 'incurable' migraines

I did The Restore Challenge in December and I had a record of 30 days without a migraine attack. This hasn't happened to me in years - normally I get 2-5 migraines a week! I haven't experienced anything like this before. It's a miracle :) - Essi, Australia

I got my period back after 2 years of being told I was infertile

After being told I would never get my period back...guess what? I've got my period back and just had my sixth healthy cycle in a row. This feels insane! You've changed my life. I want people to know that a big white man behind a desk doesn't actually know everything. - Beth, UK

Isabella knows what she is doing

Isabella always meets me right where I'm at and whenever she provides new content all I think is 'YES!!’. And then whenever I waver, she adds this extra stuff and suddenly the fire is relit again. How she keeps meeting me where I am at on my journey, is a testament to the path she is on. She knows what she is doing and is slaying it. I wish this was taught in schools, imagine the world if her work was part of the curriculum! Isabella deserves all the positivity, success, internal peace and happiness life has to offer. Thank you, Thank you, Thank you - Debbie, Australia

Processed deep grief and got my period back

"My dad passed away about 8 years ago and since then I've been suffering from panic attacks and high levels of stress. l've been doing extensive research and looking for solutions ever since and I can honestly say this is the first thing I've done that has been made an impact...I can't tell you how good that feels! I had also gone off of birth control back in April 2023 and lost my period for about 6 months. I started spotting at around day 26 of the program!" - Laina, California
