Estrobolome

Meaning

The Estrobolome refers to the collection of enteric bacteria within the gut microbiome that are capable of metabolizing and modulating the circulation of estrogens in the body. These specific microbes produce the enzyme β-glucuronidase, which deconjugates estrogens that were prepared for excretion, allowing them to be reabsorbed into the systemic circulation. A balanced estrobolome is essential for maintaining healthy estrogen homeostasis, impacting both reproductive and metabolic health.
