Selenium trimmed testosterone in PCOS but left blood sugar untouched
Pooled results from five small trials link selenium supplements to reduced total testosterone and cholesterol in women with PCOS. Blood sugar, insulin resistance and the rest of the lipid panel did not shift, and the authors urge caution.
For you: If selenium is being sold to you as a PCOS metabolic fix, worth knowing the trial evidence backs only two markers, and thinly.
What it shows: Treat gently: only five trials made the pool and the authors themselves say the finding needs caution. Most metabolic markers, including blood sugar and insulin resistance, did not move at all.Meta-analysis · Gynecol Endocrinol
