White Mulberry Leaf In GlycoAid
The leaf silkworms live on, carrying a sugar-shaped molecule called DNJ.
What It Is And Why It Is Here
The leaf of Morus alba, the tree silkworms are fed on. It has been used in traditional Chinese medicine for a very long time.
1-deoxynojirimycin, usually shortened to DNJ. It is shaped enough like a sugar to interact with the enzymes that break carbohydrate down.

Evidence: Moderate. Several human studies exist, generally small ones, and the findings are less settled than for the large-evidence ingredients on this panel.
What it is studied for
Post-meal glucose response, with a moderate research base of mostly small human trials.
The Dose Question
Studies commonly use extracts standardised for DNJ content taken shortly before a carbohydrate meal. GlycoAid publishes no amount and no standardisation, and the capsule is taken once daily rather than before each meal.

Questions About White Mulberry Leaf
What is DNJ?
1-deoxynojirimycin, the sugar-shaped molecule in white mulberry leaf that most of the research concerns.
Is white mulberry the same as the berries?
No. The label declares the leaf, not the fruit, and the research is about the leaf.
Should it be taken before a meal?
Trials often time it that way. This capsule is a once-daily product taken with a meal, which is not the same timing.
Is it safe?
At supplement intakes it is generally well tolerated, with mild digestive effects the most common report.
Judging It Fairly
No single ingredient on this panel can be assessed on its own from the outside, and no week of taking the capsule can settle anything either. Why week one tells you nothing is the short version of that argument.
How It Sits In The Formula
White Mulberry Leaf is declared inside a single 500 mg proprietary formulation alongside thirteen other ingredients, so the amount here is unknown. That is the honest position on every ingredient page on this site, and it is why the piece on blends is worth ten minutes. The ingredient before this one on the label is Biotin and the one after it is Turmeric Root.
