Seeking Optimal Thyroid Function?

The thyroid, a tiny gland located in the neck, has an enormous impact on the health and well-being of the entire person. The thyroid secretes thyroid hormone, which in turn regulates the activity of each and every cell of the body and affects maturation, growth and the speed of metabolism.

While thyroid hormone levels can be checked via blood tests, thyroid dysfunction might only be highlighted by a medical practitioner when results are severe or extreme. Optimal function of the thyroid gland is dependent on several factors: correct function of theendocrine glands, an adequate supply of iodine and the conversion of thyroxine (T4) to the active thyroid hormone T3 (triiodothyronine). When one of these factors is out of balance, the affected individual will begin to experience either hyperthyroidism (excessive amounts of thyroid hormone) or hypothyroidism (consequence of a deficient quantity of thyroid hormone).

Iodine

The NZ Food Safety Authority (NZFSA) officially recognises that New Zealanders are not getting enough iodine through their diet. Despite the addition of iodine to table salt in 1924, studies have shown that New Zealanders are still lacking this essential mineral1. Good sources of iodine include shellfish and seaweed. Those with a sluggish thyroid or those that do not consume these foods on a daily basis may prefer to opt for supplementation with Nature’s Way® Kelp or Nature’s Way® Bladderwrack as a guaranteed natural source of iodine.

Conversion of thyroid hormones

Most people diagnosed with a sluggish thyroid are prescribed thyroid medication, mainly Thyroxine (Eltroxin). While this medication is a lifesaver for many, individuals often report that symptoms such as tiredness, cold extremities and inability to loose weight remain persistent or gradually start reappearing, despite taking their thyroid medication regularly. This is extremely common. One possible reason is that T4 thyroxine), which is naturally made in the thyroid gland, is not being converted into the active thyroid hormone T3. This conversion from T4 to T3 occurs in various tissues of the body and can be affected by the use of prescription medication including the contraceptive pill, beta blockers, lithium, chemotherapy and steroidal medication. This conversion also requires an optimal supply of certain vitamins and minerals including:

• Iron (Radiance® Iron Complete)
• Selenium (Radiance® Selenium)
• Zinc (Radiance® Zinc OptiSorb)
• Magnesium (Radiance® Magnesium Complex)
• B vitamins (Radiance® B50 Complex)

Selenium in particular, a mineral deficient in New Zealand soils, may be of benefit when the thyroid is over-active or when thyroid autoimmune disorders are present.

A thyroid support regime should always include these nutrients as listed above for optimal results.

Other factors to consider

While stress has a great impact on our overall wellbeing, it has a direct impact on thyroid activity. The hormone cortisol, produced during times of chronic stress, directly affects the thyroid hormone production cascade. Supporting adrenal health by using Dr. Christopher’s Adrenal Formula or Natures’ Way® Ashwagandha and increasing relaxation time may provide a good base to establish endocrine and thyroid health. Adopting a wholesome and nutritious diet and reducing foods that may have a detrimental effect on thyroid health are all part of achieving optimal thyroid function.
