The Claim

Consumption of a ready-to-mix supplement containing white mulberry leaf extract and apple peel extract (GLUBLOC) with a high-carbohydrate meal reduces postprandial blood glucose incremental area under the curve (iAUC) by approximately 40-45% over two hours in healthy adults through inhibition of α-amylase and α-glucosidase enzymes and delayed carbohydrate absorption.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

A supplement containing white mulberry leaf and apple peel extracts, taken with a high-carb meal, reduces the rise in blood glucose by 40-45% over two hours in healthy adults by slowing the breakdown and absorption of carbohydrates.

See the scientific wording

A ready-to-mix supplement containing white mulberry leaf extract and apple peel extract (GLUBLOC), when consumed with a high-carbohydrate meal, reduces postprandial blood glucose incremental area under the curve (iAUC) by approximately 40-45% over two hours in healthy adults, likely by inhibiting α-amylase and α-glucosidase enzymes and delaying carbohydrate absorption.

Why this might work

When the supplement is taken with a starchy meal, its compounds block the enzymes that break down starch and sugar in the small intestine. This slows the release of glucose into the bloodstream, causing a smaller and slower rise in blood sugar.

  1. Study: A ready-to-mix nutraceutical supplement (GLUBLOC) lowers postprandial blood glucose levels in healthy individuals — A randomised, placebo-controlled, crossover study

    This study found that taking this specific powder with a carb-heavy meal cuts the blood sugar spike by about 40-45% and makes it happen slower, just like the claim says.
