Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — oestrogen metabolism

Most people associate iodine exclusively with thyroid health — but this essential mineral plays a far broader role in the body. From breast tissue and ovarian function to fetal brain development and endometrial health, iodine is active in virtually every organ system. Deficiency is more widespread than commonly recognised, and standard thyroid blood tests cannot reliably detect it. This guide explores the extrathyroidal roles of iodine, the difference between iodide and molecular iodine, the controversy around dosing, and why testing urinary iodine is the most accurate way to assess your status.

Most people know that drinking enough water is important for health — but far fewer understand the profound connection between hydration and hormones. Oestrogen, progesterone, aldosterone, vasopressin, and even dopamine all play roles in regulating how the body manages fluid. Hormonal fluctuations across the menstrual cycle, perimenopause, and menopause can significantly alter water retention, thirst signalling, and overall hydration status. This guide explains the science behind hydration and hormones, identifies who is most at risk of dehydration, and provides practical, evidence-based strategies for staying optimally hydrated at every life stage.

Heavy periods affect millions of women, yet the underlying causes are frequently misunderstood or left unaddressed. From oestrogen and progesterone imbalances to structural issues such as fibroids and adenomyosis, there are several well-established reasons why menstrual bleeding can become excessive. This article explains the physiology of the menstrual cycle, the most common causes of heavy periods, and how hormone testing can help identify what is driving your symptoms — so you can take informed steps towards better menstrual health.

Prostate cancer takes years to develop from a normal cell to a detectable tumour — which means there is a meaningful window for prevention. Three key risk factors are both testable and modifiable: BPA exposure, arsenic accumulation, and catechol oestrogen imbalance. This article explains how each one works and what men can do about it.
