Your thyroid is a small, butterfly-shaped gland located in the lower front part of your neck. Its job is to secrete hormones that control growth/development during childhood, regulate your metabolism and body temperature, and drive the production of many neurotransmitters in your brain. Specifically, the ones that help you feel good and enough have motivation to accomplish your goals: serotonin, dopamine, adrenaline, and noradrenaline.

It’s estimated that tens of millions of people worldwide have thyroid problems—anywhere from 5-25% of the world’s population. In the book, Thyroid Mind Power, it’s reported that, “the last 40 years have witnessed a massive increase in the amount of hormone-disrupting synthetic chemicals, finding their way into our air, food and water…The most sensitive and highly susceptible of human tissues turned out to be the thyroid gland.”

Neurotransmitters, Mood & the Perception of Stress

Posted by Dr. Thomas Guilliams on Friday, 06 April

When we talk about “stress,” or allostatic load, in terms of the perception of an event, we must realize that these “events” must first be translated into neurochemical signals before they trigger the HPA axis.

Therefore, the sensitivity and outcome of translating these events (whether they are ongoing events, memories of past events, or stressful anticipation of unrealized events), is highly dependent upon signaling from other neurotransmitters. In fact, the signaling neurotransmitters that manage mood and affect often overlap with measures of HPA axis activation, and cannot be easily distinguished in some subjects. [1]

Lithium is an element that, at the present time, is considered non-essential to the human body. However, it is getting a lot of attention as a therapy, and there are interesting reports of beneficial actions of lithium. 

You might have seen our blog by Dr. James Greenblatt or one of the NY Times articles mentioning lithium. It is also coming up with frequency because of increasing awareness on mental health issues. There are lots of questions still to be answered, but we are excited about delving into them with you.

For this blog, I wanted to take a moment to introduce a new test for ZRT that ties in with our nutritional elements testing – lithium in dried urine.

Is Sweating a Good Bet for Heavy Metal Detox?

A couple years back, I wrote a blog about iodine deficiency in athletes resulting from excessive sweat loss.

Later, while studying the kinetics of the iodine loading test which involves taking a 50-mg dose of iodine and collecting urine for 24 hours, I investigated the excretion of iodine in sweat along with urine.

Surprisingly iodine levels in sweat tracked urine iodine excretion over a period of 3 days. The goal was to show that the loss of iodine through sweat can represent a significant portion of the 50-mg dose, something the creators of the Iodine Loading Test had not accounted for.
