Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — hormone and wellness optimisation

Many women going through menopause notice changes in their ability to remember things — and this is not just in their heads. A small, seahorse-shaped structure in the brain called the hippocampus is highly dependent on estrogen for synaptic plasticity, memory formation and neuroprotection. In this article, Margaret Groves of ZRT Laboratory explains the science behind menopause-related memory changes, why estrogen receptor expression declines with age, and why the “window of opportunity” for hormone replacement is critical to preserving cognitive function.

Hot flashes, mood instability, brain fog and memory changes during perimenopause are not “all in your head” — but they are very much in your brain. In this in-depth clinical article, Dr. Kate Placzek of ZRT Laboratory explains how declining estradiol disrupts brain glucose metabolism, neurotransmitter signalling and thermoregulation, why perimenopause represents a window of neurological vulnerability, and why the timing of hormone replacement therapy is critical to protecting long-term brain health.

Imbalances in estrogen, testosterone, progesterone and cortisol — brought on by ageing, diet and modern-day stress — are key drivers of the obesity epidemic. Learn how your hormones influence fat distribution and weight regulation, and how at-home hormone testing can help you take control.
