What is thyroid function?

The thyroid is stimulated by thyroid stimulating hormone (TSH) and produces two hormones triiodothyronine (T3) and thyroxine (T4).

It is through these hormones that the thyroid regulates the body’s metabolism. Thyroid disorders are very common however the symptoms can frequently be confused with other conditions; tiredness, weight gain, feeling cold, poor concentration, depression, weight loss, heat intolerance, rapid heart rate and anxiety.

Before looking at thyroid support it is essential that you understand your levels as certain thyroid conditions will benefit more from some of these nutrients than others and too much iodine can actually be detrimental to a healthy thyroid. If you are on thyroid medication it is important to speak to you GP before taking any supplements as certain nutrients like calcium or iron and those containing magnesium can interact with thyroid medication.
