Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — dopamine and motivation

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.

Neurotransmitter testing is one of the most powerful functional assessment tools available — but it requires a nuanced approach to interpretation. In this clinical overview, Dr. Kate Placzek of ZRT Laboratory outlines the key fundamentals every practitioner needs before reading a neurotransmitter report: from understanding patterns over numbers and treatment sequencing, to the clinical significance of low serotonin on SSRIs, GABA’s peripheral mechanisms, and when to run a diurnal catecholamine assessment.
