Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — tsh test

Toxic heavy metals and essential nutrient imbalances can silently undermine your health. Discover how at-home elements testing using dried urine and blood spot samples can uncover what standard tests miss.

The thyroid is a small butterfly-shaped gland located in the front of the neck, just below the Adam's apple. It plays a crucial role in regulating various bodily functions by producing hormones that control metabolism and energy production. Thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3), influence the functioning of almost every organ in the body, including the heart, brain, muscles, and skin.The thyroid gland functions under the control of the hypothalamus and the pituitary gland. The hypothalamus releases thyrotropin-releasing hormone (TRH), which signals the pituitary gland to release thyroid-stimulating hormone (TSH). TSH then stimulates the thyroid gland to produce...

Iodine deficiency is a significant and underappreciated global health problem, with urinary iodine levels in many Western populations having fallen substantially over recent decades. As an essential component of thyroid hormones, iodine deficiency impairs thyroid function, promotes goitre, and has wide-ranging consequences for metabolism, cognitive development, breast health, and reproductive health. Women of childbearing age are particularly vulnerable. This article explains the causes and consequences of iodine deficiency, who is most at risk, and how at-home dried urine testing using ICP-MS analysis can accurately confirm your iodine status.

Iodine is an essential trace element required for thyroid hormone production, yet many people are unknowingly deficient. While iodised salt and seafood are well-known sources, dairy products, eggs, and seaweed also contribute significantly to daily intake. Changing dietary habits — including reduced milk consumption and the replacement of iodine with bromine in bread production — are quietly lowering iodine intake across the population. This article explains where dietary iodine comes from, why the body needs it, how it is absorbed and excreted, and how at-home urine testing can confirm whether your intake is adequate.

Iodine deficiency is more common than many realise. This guide walks through how to assess iodine status using dietary recall, symptom profiling, and a three-part laboratory panel — including thyroid function, thyroglobulin, and urinary iodine and bromine testing.
