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

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.

At-home hormone testing using saliva, dried blood spot and dried urine collection is not only more convenient than clinic-based blood draws — it is also safer, more accurate for certain hormones, and essential for capturing time-sensitive samples like waking cortisol or first-morning melatonin. This article explains how each collection method works, why dried samples carry minimal infection risk, and how ZRT Laboratory’s CLIA-certified processes ensure reliable results.

Thyroid cancer is now among the top 10 most common cancers worldwide, with incidence rising by an average of 5.5% per year. But experts are divided: is this a genuine epidemic, or an epidemic of diagnosis driven by more sensitive imaging? This article reviews the evidence on both sides, explores the role of iodine deficiency, radiation exposure and environmental factors, and explains why thyroid awareness — and monitoring — matters year-round.

Breast cancer is not one disease — it encompasses many distinct types with different attributes, degrees of invasiveness and treatment responses. Understanding the difference between invasive and non-invasive cancers, what hormone receptor status means, and which risk factors are modifiable can help women make more informed decisions about screening, lifestyle and hormone health. This article provides a clear, evidence-based overview.

Vitamin D has one of the most remarkable stories in nutritional science — from its discovery as the cure for rickets in the early 20th century to its emerging role in cancer prevention, heart disease, diabetes and depression. Yet a century after its identification, our understanding of vitamin D’s wider role in human health is still evolving. This article traces that history and explains why testing your vitamin D levels remains as relevant as ever.
