Not All Supplements Are Created Equal

What I've learned is that not all supplements are created equally. As a pharmacist, I can tell you that many supplements are ineffective, and some are even downright unsafe.

The truth is that most supplement companies do not undergo the same scrutiny and testing that pharmaceutical products do, because many of the tests which are required of pharmaceutical companies are voluntary for supplement companies. For this reason, most supplement companies do not take the extra steps to test their products to ensure safety and purity.

Evaluating the safety, efficacy, and cost of various treatment was a large part of my training as a pharmacist. I have put my training to good use in overcoming Hashimoto's, and now, in the development of my own supplement line, Rootcology.

Rootcology is a blend of my two passions and areas of expertise, root causes and pharmacology!

Rootcology is dedicated to creating innovative, bioavailable products that are made with the greatest care, and with the highest quality ingredients available. All of the supplement ingredients have been carefully chosen by yours truly, to address the needs and sensitivities of people with autoimmune thyroid disease.

Furthermore, all Rootcology supplements undergo third-party testing to ensure that the ingredients on the label are safe, effective, and match what's actually inside the bottle.

I created Rootcology to give you a trusted source of supplements that are safe and helpful for people with multiple sensitivities and chronic health conditions. I'm honored to be a part of your healing journey!

About Dr. Wentz

Dr. Izabella Wentz, Pharm.D., FASCP is a passionate, innovative and solution focused clinical pharmacist. Fascinated by science and the impact of substances on the human body, Izabella decided to pursue a doctorate degree in pharmacy with a dream of one day finding a cure for a disease.

During her time as a consultant pharmacist, Dr. Wentz worked as part of an interdisciplinary team consulting on thousands of complicated patient cases, often caused by rare disorders. She was regarded as an expert in clinical pharmacology and would be called to investigate cause and effect by performing comprehensive medication therapy reviews to help identify and resolve adverse drug events. She quickly became well versed in finding and evaluating emerging research to help address her clients' unique challenges. Although trained as a pharmacist, she was an ardent champion for lifestyle interventions, which often helped patients much more than any medications.

After a personal diagnosis of Hashimoto's thyroiditis, an "incurable disease" Dr. Wentz decided to apply her clinical and research skills to getting her health back and has since become a powerful voice for integrative treatments of chronic illness. She is a two-time New York Times Bestselling author of Hashimoto's Thyroiditis: The Root Cause and the #1 NY Times bestselling book Hashimoto's Protocol, and a highly sought after speaker and clinician.

Why Rootcology?

Rootcology focuses on the fundamentals of healing through supporting four key systems. I created Rootcology to help you support each of these systems with high quality nutrition and supplements.


The Protocols...

The Liver Support Protocol

supports the body’s own detoxification pathways, and makes the body more resilient to environmental toxins. This first step is very important in order to reduce inflammation, oxidative stress, and mitochondrial injury.

The Adrenal Protocol

aids in balancing the adrenals and blood sugar levels, and can help you start tackling chronic stress and inflammation.

The Gut Protocol

helps in healing intestinal permeability and helps with symptoms like bloating, stomach pain, diarrhea, and constipation. It also focuses on removing reactive foods, balancing your gut flora, and supplementing with enzymes and other beneficial foods for your gut.

The Advanced Protocols

focus on identifying and resolving residual root causes such as toxicity, chronic infections and traumatic stress, and offer guidance on proper hormone optimization and utilizing advanced nutrition protocols. With the guidance of the Liver, Adrenal, Gut and Advanced Protocols, you can take a proactive approach in finding and correcting your root causes and getting your life back!

Don't Know Where To Start?

If you're feeling hopeless and feel like giving up, please don't... you're not alone in this.

If you are feeling overwhelmed and don't know where to begin, I suggest that you start by getting a copy of my latest book, Hashimoto's Protocol, a step-by-step guide that covers the tests, lifestyle interventions and protocols that I recommend after years of research.
