Mulberry fruit extract
In a double-blind crossover, mulberry leaf significantly lowered the insulin rise two hours after a meal.
What the evidence shows
Every line below is carried on the blend page that makes the claim. Follow it to the pathway and its sources.
In a double-blind trial of 84 adults, mulberry fruit extract blunted the blood-sugar and insulin spike after a carbohydrate meal, more robustly than its isolated active.
Mulberry leaf carries DNJ, an iminosugar that occupies alpha-glucosidase before starch can — the meal's glucose trickles into the blood instead of surging.
Mulberry leaf’s DNJ blunts starch digestion; a placebo-controlled trial improved glucose tolerance and lowered insulin — defending against the glycemic swings obesogens amplify.
A pooled analysis and an independent human trial both report lowering, making this an early but consistent human signal.
