Zinc, Exercise and Thyroid Health

Zinc, Exercise and Thyroid Health

Zinc is a popular nutrient, especially lately in the wake of the infectious disease pandemic. 

Zinc deficiency is linked with low serum testosterone levels and immune dysfunctions mainly affecting T helper cells, excess of ammonia in the blood and neurosensory disorders (1,2).

“Many organs are affected by zinc deficiency, especially the immune system which is markedly susceptible to changes of zinc levels. It seems that every immunological event is influenced by zinc somehow.” (2)

Below is a wonderful image that illustrates the roles zinc plays throughout the body (3).



Zinc and Thyroid Health


One study found that four months of zinc supplementation (26 mg per day) had a favorable impact on thyroid function and resting metabolic rate in female athletes (4). Another study in overweight hypothyroid females found that 30 mg of zinc per day had a favorable effect on serum thyroid hormone levels (5).


Zinc, Exercise and Sweat


Many people are aware that sweat increases the loss of minerals such as sodium, potassium, magnesium and more. But zinc also is lost in sweat. In fact, one study found that sauna therapy increases the loss of zinc more than other minerals (6). So, if you exercise, do hot yoga or harness the health benefits of sauna therapy, you may want to consider supplementing with one or two caps of Zinc Absorb daily*.


How to Do the Zinc Taste Test (ZTT) at Home


A mentor of mine taught me about the zinc taste test (ZTT) many moons ago. It works because zinc is involved in the perception of taste (7).


Here are more details about how to do it: This DIY test is super simple:


1) One day a week (usually the same day), take a swig of liquid zinc, let it sit in your mouth for 20 seconds and then swallow or spit it out. If you have no metallic taste, keep supplementing with 25-50 mg of Zinc Absorb daily.


2) A week later (e.g., the following Sunday, etc.) take another swig, let it hang out in your mouth for about 20 seconds and swallow or spit it out. if you don’t notice any metallic taste, keep supplementing. For many people, after a few weeks of supplementation they’ll begin to notice a more metallic taste when they swig the Aqueous Zinc. This way you’ll have a better idea about when you’ve replenished your zinc levels.


Why do all this? Zinc and copper have a delicate balance, so overdoing the zinc can create unintended issues.


Since this liquid zinc is actually quite affordable (and you’re stuck at home), I thought you might want to know about it!
