Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — women over 40

Explore the vital role of estrogen in perimenopause, its impact on mood, sleep, heart and bone health, and the latest research on hormone therapy options.

The latest research confirms what Dr. John Lee and Dr. David Zava argued decades ago: maintaining healthy progesterone levels in proper balance with oestrogen is one of the most powerful tools women have for preventing and recovering from breast cancer. This article outlines seven practical steps to restore hormone balance and reduce breast cancer risk.

A landmark study published in Nature confirmed what Dr. John Lee and Dr. David Zava argued over a decade ago: natural progesterone — unlike synthetic progestins — can slow or even shrink ER+/PR+ breast cancer tumours. This article explains the receptor science behind the findings and what it means for women’s hormone health.

Hormonal contraception suppresses ovarian function, which means saliva and blood spot hormone test results will appear artificially low — but this doesn’t mean hormone levels at the tissue level are low. This guide explains how to interpret hormone test results correctly when using the pill, patch, ring or IUD, and when to collect your sample for the most meaningful data.

Hot flashes and night sweats affect up to 80% of women during perimenopause — but they are not inevitable, and they are not forever.

Discover the lifestyle changes, natural supplements and hormone testing strategies that can bring real relief.
