What is the Thyroid?

The thyroid is a butterfly shaped gland in the neck that produces a hormone that affects every part of your body, governing your metabolism. There are millions of North Americans with poor thyroid health, of which half are undiagnosed. The thyroid hormone affects every system in the body by:

  • regulating metabolism
  • building muscle
  • coping with stress
  • regulate protein, fat & carb metabolism
  • affecting body temperature
  • controlling heart function, heart rate & circulation


What affects Thyroid Health?

When the thyroid gland produces too little or too much of its hormone, the body starts to become symptomatic either way.  Normally, the thyroid hormone produced is inactive, and needs to be converted to its active form in the tissues.  There are so many steps for optimal thyroid health and things can go wrong at each level.  Thyroid health can be compromised by affecting the body’s production, conversion or use of thyroid. Many things can cause thyroid dysfunction.
