Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — functional health assessment

Brain Chemistry Balance: When Neurotransmitter Testing Changes Lives - from brain fog to focus, see how tailored insights spark calm, clarity and wellbeing.

Chronic stress, fatigue, anxiety, and poor sleep may be signs of cortisol imbalance. Learn how stress and sleep hormone testing — including the Cortisol Awakening Response (CAR) and diurnal cortisol rhythm — can identify HPA axis dysfunction and help uncover the root cause of burnout, energy crashes, and disrupted sleep.

Neurotransmitters play a vital role in regulating mood, sleep, energy, focus, and overall mental wellbeing — yet imbalances often go undetected. This article explores how dried-urine neurotransmitter testing provides an objective, science-based way to identify chemical patterns behind symptoms such as anxiety, depression, fatigue, insomnia, ADHD, and chronic stress. By analysing key markers including serotonin, dopamine, GABA, glutamate, histamine, and the kynurenine pathway, clinicians can create highly personalised treatment plans that target each individual’s unique neurochemical profile. Discover how this innovative testing method offers a deeper understanding of mind-body chemistry and a more precise path to restoring balance and emotional health.

Single nucleotide variations (SNVs) in the enzymes that metabolise estrogen can significantly alter breast cancer risk — in some cases by as much as 12-fold when multiple variants combine. In this detailed scientific overview, Jillian Harrington PhD of ZRT Laboratory explains how variations in CYP11A1, CYP19A1 (aromatase), CYP1B1, COMT and MnSOD affect the estrogen metabolism pathway, why catechol estrogens are dangerous, and how methylation testing can reveal individual vulnerability.

What do heavy metals, neurotransmitters and hormone imbalances have in common? In this detailed case study, Dr. Kate Placzek examines Loretta — a 62-year-old postmenopausal woman with breast cancer — and shows how comprehensive testing can reveal the complex biochemical picture behind a cancer diagnosis. A compelling read for anyone interested in the role of hormones and toxic exposure in breast health.
