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

The human microbiome and the endocrine system are deeply interconnected, engaging in a complex two-way conversation that influences everything from mood to metabolism. One of the most fascinating areas of this interaction centers on estrogen and the gut—a relationship governed by what’s now known as the estrobolome.

Single nucleotide variations (SNVs) in the enzymes that metabolise estrogen can significantly alter breast cancer risk — in some cases by as much as 12-fold when multiple variants combine. In this detailed scientific overview, Jillian Harrington PhD of ZRT Laboratory explains how variations in CYP11A1, CYP19A1 (aromatase), CYP1B1, COMT and MnSOD affect the estrogen metabolism pathway, why catechol estrogens are dangerous, and how methylation testing can reveal individual vulnerability.

Weight loss failure is rarely just about willpower or diet — hormones are almost always involved. In this Q&A, Dr. Alyssa Burns-Hill of ZRT Laboratory tackles the most common questions from people struggling to lose weight despite their best efforts: from thyroid interference by the contraceptive pill and stress-driven cortisol cravings, to estrogen-reducing supplements, natural progesterone for menopause, and why 5-HTP can be a game-changer for mood, sleep and comfort eating.

Estrogen dominance — an excess of oestrogen relative to progesterone — is one of the most common hormonal imbalances in women. From heavy periods and mood swings to breast tenderness and weight gain, the symptoms are wide-ranging. Discover the causes, what to test, and how to restore balance.

One in eight women will be diagnosed with breast cancer in their lifetime. But many risk factors are modifiable — including hormone imbalance and excess weight. Discover the two most important actions women can take to reduce breast cancer risk, and how hormone testing can help identify hidden imbalances before they become a problem.
