New evidence
A meta-analysis of 230 pregnant women found 200 µg/day selenium cut fasting blood sugar by about 5 mg/dL — though insulin resistance and lipids showed no clear benefit
This is early, small-scale evidence that selenium might help manage one aspect of gestational diabetes, but because the total sample is only 230 people and other important markers didn't budge, it's far from a slam dunk.
In pregnant women with gestational diabetes, taking 200 µg of selenium daily was linked to a meaningful drop in fasting blood sugar — about 5 points on the glucose scale. However, the same meta-analysis found no significant improvement in insulin resistance or cholesterol levels, so the effect appears specific to glucose rather than a broad metabolic fix.
Where this fits in the evidence
This is among the first studies we've indexed on Selenium for Improved Fasting Plasma Glucose — treat it as an early signal until more research accumulates.
