This is one of the most under-recognized parts of the menopausal transition.
The estrobolome is the collection of gut microbes that help regulate the estrogen circulating in your body. When they are diverse and active, hormone clearance works. When they become less active or less diverse, hormone metabolism becomes messier.
This affects mood, weight, breast tissue, energy, and how you experience the transition itself.
Care for these bacteria is care for your hormones. Fibre feeds them. Fermented foods diversify them. Alcohol and ultra-processed food deplete them.
