How The Gut Microbiome Influences Estrogen After Menopause with David Meriwether, PhD | MGC Ep. 110

The Mind-Gut Conversation Podcast

Show Notes

Menopause is often described as a simple decline in estrogen production, but emerging microbiome research suggests the story is far more complex.

In this episode of The Mind–Gut Conversation, Dr. Mayer is joined by Dr. David Meriwether, a scientist at UCLA’s Goodman Luskin Microbiome Center, to discuss the estrobolome — a specialized group of gut microbes that recycle and reactivate estrogen after it has been excreted by the body.

They explore how gut microbes may contribute to circulating estrogen levels even after menopause, why menopausal symptoms vary so widely among women, and how changes in the microbiome may create feedback loops that influence symptom severity. The discussion also places this research in the broader context of recent findings published in Nature linking the gut microbiome to health, aging, and disease.

This episode offers an in-depth, evidence-based look at a new biological framework for understanding menopause, and the potential for future non-hormonal strategies rooted in the brain–gut–microbiome system.

Topics discussed include: • What the estrobolome is and why it matters • How gut microbes recycle estrogen after menopause • Why some women experience fewer menopausal symptoms than others • The interaction between the gut, hormones, and aging • Where microbiome-based therapies for menopause may be headed

This is a practical, science-driven discussion for anyone interested in women’s health, menopause, and the evolving role of the gut microbiome.

After 45 years of research on how the brain and the gut communicate, the question Dr. Emeran Mayer hears most often is not about mechanisms or studies. It is much simpler than that. People tell him they understand the science, they just do not know how to live it.

For most of the last forty years, irritable bowel syndrome was treated as a problem of the gut alone. The idea that the brain plays a central role took decades to gain acceptance, and it remains contested today.
