How To Treat The Root Cause Of Thyroid Problems

Ep. 603

This episode is sponsored by Paleovalley and Pendulum.

Thyroid disease affects one in five women and one in ten men, yet 50 percent of people with thyroid disease go undiagnosed. The main role of thyroid hormone is to stimulate metabolism, and it affects almost every function of the body. That’s why thyroid imbalance can cause so many different symptoms.

In today’s episode of a new series called Health Bites, I discuss thyroid disease and why an out-of-whack thyroid can stall your metabolism and create many other problems. I also share why using a whole-foods diet, nutritional supplements, and optimizing thyroid hormone replacement is critical for addressing thyroid disorders.

Ep. 638
This episode is brought to you by Rupa Health and Athletic Greens.CoQ10 is a compound whose job is to help cells generate energy, so it’s no surprise there are so many wonderful benefits to getting enough of this critical coenzyme. Although you can find it in supplement form, it is also naturally produced by the body. Unfortunately, however, as you age the production of CoQ10 declines. It also declines with chronic stress, toxin exposures, and certain medications. The decreased amount of CoQ10 in your cells contributes to the gradual loss of energy that most of us experience in our thirties and beyond. In today’s episode of my series I’m calling Health Bites, I am talking all about coenzyme Q10, also known as CoQ10—what it is, what it can do for us, and how to ensure we are getting enough of this critical nutrient.This episode is brought to you by Rupa Health and Athletic Greens.Rupa Health is a place where Functional Medicine practitioners can access more than 2,000 specialty lab tests from over 20 labs like DUTCH, Vibrant America, Genova, and Great Plains.
