Your Labs Say You’re Fine,
Your Body Says Otherwise
Dr. Cassie Smith’s upcoming book, Fix Your Gut, Fix Your Hormones, explores the overlooked connection between gut health and hormonal symptoms... and why so many women are left without real answers.
"When I first started the program, I had maybe 60 connections on LinkedIn but after using this process, I was able to grow that network to over 600 in just 5 weeks and land my dream job in sales working for a company that values me."
Gordon
"When I started the program, I was earning $48K at my previous position but now I am making $75K plus an annual $10K bonus at my dream job."This program changed my life."
Melanie
"I didn't just find a job, it changed my life. I had to lean in and trust the process quite a bit because this is not about just getting a job... it changed my career and my life. I am making substantially more money, 1.5X my original income."

"'Fix Your Gut, Fix Your Hormones' is the book I wish more people had sooner. Dr. Cassie Smith simplifies gut and hormone health in a way that’s science-backed, practical, and doable."
Dr. Becky Campbell
You’ve done the tests.
You’ve followed the advice.
You’ve tried to “do everything right.”
And yet, you still feel exhausted, bloated, anxious, and stuck in a body that doesn’t feel like your own.
When you ask for answers, you’re told your labs are normal. That nothing is wrong. That this is just stress, aging, or hormones.
But you know better.
Dr. Cassie Smith has seen this pattern over and over in women who feel dismissed by conventional medicine.
As a dual board-certified endocrinologist, she discovered that many hormone symptoms aren’t random, they’re rooted in the gut.
Fix Your Gut, Fix Your Hormones will give you the missing connection your doctor isn’t looking at, and a clear, science-backed path to finally feel better.
But before it launches, we want to give you access to bonus resources to help you start healing now.

A message FROM DR. CASSIE
If you’ve made it this far, I want you to know something important: you’re not broken, and your symptoms are NOT “just part of getting older.”
I’ve worked with thousands of women who were told their labs were normal while their bodies were clearly saying otherwise. They felt exhausted, frustrated, and dismissed... yet deep down, they knew something wasn’t right.
That’s exactly why I wrote Fix Your Gut, Fix Your Hormones.
This book is not about quick fixes or generic advice. It’s about finally understanding what’s happening inside your body and giving you a clear, science-backed path to real healing. Whether you’ve tried everything or you’re just beginning your journey, this is your starting point.
You deserve answers. You deserve to feel energized, balanced, and in control of your health again.
And this book was written to help you get there.
"Dr. Cassie Smith’s book is a revelation for anyone struggling with gut issues and hormonal imbalances.
She masterfully links the microbiome to chronic symptoms like fatigue, bloating, and mood swings, offering a clear, science-backed path to healing. Her 10-step plan is practical and transformative... a must-read for anyone ready to revitalize their health!"
