Gut & MicrobiomeDietary Fiber Helps Gut Bacteria Convert Androgens Into a Nonandrogenic Metabolite
A clinical trial suggests that a blend of inulin, resistant starch, and beta-glucan can lower blood androgen levels in women with polyendocrine metabolic ovarian syndrome (PMOS). Researchers linked the fiber intervention to greater abundance of a gut bacterium called Bacteroides xylanisolvens. This bacterium converts an androgen precursor into coproandrosterone, a newly identified substance described as nonandrogenic. Other gut microbes then process it further. The researchers also confirmed the conversion pathway in mice. These findings suggest that dietary fiber could influence hormone balance through gut bacteria, potentially guiding future nutritional treatments. However, the abstract does not report participant numbers, fiber doses, treatment duration, or the size of the hormone changes. It also does not establish symptom improvements. This summary is based on the abstract only, so the findings do not justify replacing established treatment with supplements.
