Equol is a compound produced by gut bacteria during the metabolism of the soy isoflavone daidzein. It acts as a non-steroidal estrogen and may have various health benefits, including antioxidant and hormone-balancing effects. However, only some individuals host the specific gut bacteria capable of producing equol. Measuring equol in stool helps determine whether the gut microbiome can convert daidzein efficiently, providing insight into microbial diversity and function related to estrogen metabolism.
Equol is a metabolite formed by gut bacteria from the soy isoflavone daidzein, and it has estrogen-like activity.
To assess whether your gut microbiome can convert daidzein into equol, which reflects specific microbial functionality.
Yes, equol is considered beneficial due to its antioxidant properties and potential to support hormone balance.
No, only about 30–50% of people have the gut bacteria necessary to produce equol from soy isoflavones.
