Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — #Selenium

Brazil nuts are widely used as a natural selenium supplement, but the selenium content in each nut varies enormously depending on soil conditions, region, and even individual trees. While selenium is essential for thyroid function, antioxidant defence, and overall health, both deficiency and excess carry serious risks. This article explains why Brazil nuts are so variable as a selenium source, what the safe daily intake looks like, and why testing your selenium levels is the most reliable way to know whether your intake is adequate, insufficient, or dangerously high.

Selenium is an essential trace element required for thyroid hormone activation, antioxidant defence and selenoprotein synthesis — yet it is one of the most commonly overlooked nutrients. Too little increases cancer risk; too much is toxic. This article explains the different forms of selenium found in food and supplements, which forms are best absorbed, their anti-cancer properties, and how to determine whether your selenium status is optimal.

Bromine has long been considered a non-essential trace element — but groundbreaking research published in Cell suggests it may be the 28th essential element required for collagen IV formation and connective tissue development. This article explores the science behind bromine’s newly discovered role, its toxicity risks (bromism), its interactions with iodine and thyroid function, and why measuring bromine alongside other elements may be clinically relevant.

Learn why the biological sample used for element testing — urine, whole blood, serum, hair, or nails — can dramatically change how toxic and essential mineral results are interpreted. Discover how different sample types reveal recent intake, long-term exposure, body burden, deficiency, or chronic toxicity for elements like mercury, lead, cadmium, arsenic, selenium, zinc, copper, iodine, and magnesium, and why choosing the correct testing method is critical for clinically meaningful results. 

The contraceptive pill is one of the most widely used medications in the world — but its effects on mood, brain chemistry and hormone balance are still poorly understood. This article explores how synthetic hormones disrupt oestrogen, progesterone, cortisol and neurotransmitters, and why some women are far more vulnerable to depression and anxiety as a result.
