Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — dried blood spot

The rise in cardiovascular disease (CVD), obesity, and type 2 diabetes (DM2) is one of the most pressing health concerns of our time. CVD remains the leading cause of death for both men and women in the United States. Alarmingly, obesity and insulin resistance—precursors to DM2—significantly increase the risk of developing CVD. Yet, these conditions are largely preventable with early detection and lifestyle changes. So, how can we spot the danger before it's too late? What is CardioMetabolic Risk? Cardiometabolic risk refers to a cluster of modifiable risk factors and biological markers that signal an increased likelihood of developing CVD and...

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.
