Essential and Toxic Elements: What Your Body Might Be Telling You Our bodies rely on a careful balance of essential elements to function optimally, but we're also exposed to potentially toxic elements through everyday environmental and dietary sources. Identifying the right levels of these elements can have a profound impact on health. Let’s explore what each element reveals and how advanced testing methods like dried urine and dried blood spot (DBS) testing provide critical insights. Essential Elements Iodine Iodine is critical for thyroid hormone production (T4 and T3). Found in dairy, seafood, iodized salt, and grains, this nutrient must be...
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.
Inositol is a naturally occurring sugar alcohol found in foods such as beans, grains, nuts, and fresh produce. Beyond its well-established role in insulin signalling and PCOS management, inositol has been studied extensively for its effects on mood and mental health. Clinical trials have demonstrated benefits in panic disorder, obsessive-compulsive disorder, depression, premenstrual dysphoric disorder, and binge eating. This guide reviews the evidence, explains how inositol influences neurotransmitter pathways, covers dosing and safety considerations, and explains why laboratory testing is the most reliable way to determine whether inositol supplementation is appropriate for you.
Saliva hormone testing is one of the most accurate and convenient ways to measure bioavailable hormones — the fraction that is actually active in your body's tissues. Unlike standard blood tests, which measure total hormone levels including protein-bound fractions that cells cannot use, saliva testing captures only the free, unbound hormones that drive real physiological effects. This guide explains how saliva testing works, which hormones it measures, why it is clinically superior for monitoring hormone therapy, and how to choose the right test for your health goals.
