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

Cardiovascular disease is the leading cause of death in women, and the risk dramatically increases with menopause as estrogen levels decline. In this in-depth clinical article, Dr. Sherry LaBeck of ZRT Laboratory explains how estrogen protects the cardiovascular system through nitric oxide production, endothelial function, blood lipid regulation and anti-inflammatory mechanisms — and why the timing of estrogen replacement therapy is critical to its cardioprotective effect.

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.

Hot flushes, night sweats, anxiety, insomnia and brain fog — menopause can feel overwhelming. But what is actually happening biochemically? In this case study, Dr. Kate Placzek and Dr. Allison Smith walk through the test results of Julia, a newly postmenopausal woman, showing exactly how hormone and neurotransmitter imbalances drive menopausal symptoms — and what can be done about it.

In perimenopause, falling estradiol doesn’t just trigger hot flashes — it disrupts serotonin production, driving mood swings, brain fog and sleepless nights. Discover the hormonal science behind “the change” and how testing can help.
