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

The gut microbiome and estrogen are more closely connected than most people realise. As estrogen declines in menopause, microbial diversity falls with it — triggering a cascade of metabolic consequences including weight gain, abdominal fat, inflammation and reduced insulin sensitivity. Dr. Kate Placzek explores the science behind the estrobolome and explains why supporting both gut health and hormone balance is essential for metabolic wellbeing in menopause.

Nearly a third of the UK population suffers from insomnia — yet many are still unaware of the powerful connection between hormones and sleep. When cortisol and melatonin fall out of rhythm, or when neurotransmitters are disrupted by menopause or chronic stress, restorative sleep becomes elusive. Find out whether hormones are contributing to your sleep loss — and what you can do about it.

As the days shorten and sunlight fades, four key hormonal systems come under pressure: vitamin D, serotonin, cortisol and melatonin. For those susceptible to Seasonal Affective Disorder (SAD), the disruption of these interconnected rhythms can trigger depression, fatigue, poor sleep and low mood. This article explains the science behind the SAD hormone pattern — and what you can do to support your body through the darker months.

The Women’s Health Initiative (WHI) trial cast a long shadow over hormone replacement therapy — but it enrolled women well over a decade past menopause. Two newer trials, ELITE and KEEPS, specifically studied HRT started early in the postmenopausal period. Their findings on cardiovascular health, sexual function, sleep, mood and cognition paint a more nuanced and encouraging picture. Here is what the latest research shows.

An FDA-approved testosterone gel was shown to significantly increase cardiovascular risk in older men — but does this mean testosterone therapy is dangerous? ZRT Laboratory’s research suggests the real problem lies in how testosterone is measured. Venous serum testing dramatically underestimates tissue exposure to topical testosterone, leading to pharmacological overdosing that goes undetected. This article explains why the testing method matters as much as the dose.
