Thyroid hormone imbalances are notoriously under-diagnosed,
yet can explain a wide variety of symptoms and as recent studies
have shown significantly impact sports performance and attainment
of optimal body-composition.



Thyroid disease or dysfunction can explain a wide variety of symptoms (see list on page 3), yet it is notoriously under-diagnosed. The Colorado Thyroid Disease Prevalence Study published in 20001 found that 9.9% of the study population consisted of people who were not being treated for thyroid problems yet had abnormal thyroid function test results, suggesting that their thyroid disease was previously undiagnosed. This study also found a significantly greater incidence of thyroid dysfunction in women than in men in each decade after the age of 34.

Thyroid function can be affected by nutritional deficiencies, particularly iodine and selenium, and by environmental exposure to bromine, arsenic, selenium, mercury and cadmium. We are all, to varying degrees depending on our dietary choices, our supplementation routine, or our lifestyle, exposed to the elements iodine, bromine, selenium, arsenic, mercury, and cadmium. These elements are present in the food we eat, air we breathe, and water we drink, as a result of pollution as well as natural occurrence, and are generally tasteless, odorless, and impossible to detect without sophisticated instrumentation.
