White mulberry is what silkworms eat, and silk production is the reason the tree spread from Asia across the rest of the world. Its leaf has a separate life in Chinese medicine.
The compound that makes it interesting is 1-deoxynojirimycin, mercifully shortened to DNJ. Its shape is close enough to glucose that the enzymes responsible for digesting carbohydrate latch onto it and then cannot proceed.
What the research shows
As plant mechanisms go this one is unusually clean. DNJ inhibits alpha-glucosidase, the intestinal enzyme that splits larger sugars into absorbable glucose, which is the same route a prescription medicine called acarbose takes.
Human studies are small in scale but agree in shape: mulberry leaf extract taken ahead of a carbohydrate load blunts the peak that follows. The catch is timing, because an enzyme blocker only helps while the carbohydrate is actually arriving.
Evidence grade: Moderate
Human trials exist and agree in direction, but are small, short or unevenly run.
What that means inside GlycoAid
Ninth on the list. That timing point connects directly to how the product is taken: the label says with a meal, which is exactly the window an ingredient of this kind needs. Whether the DNJ content comes near a studied level is not published.
Everything above describes white mulberry leaf as a named substance at doses used in published work. It does not describe GlycoAid, which declares one combined 500 mg covering all fourteen ingredients and publishes no individual amount.
Cautions and interactions
- Slowing carbohydrate digestion can produce bloating, wind and loose stools, the same profile as acarbose and for the same reason.
- It can add to the effect of glucose-lowering medication.
- Not advised in pregnancy or while breastfeeding.
- Discontinue before planned surgery.
Questions About White Mulberry Leaf
Three that come in most often about this ingredient.
What does DNJ stand for?
1-deoxynojirimycin, the mulberry leaf compound that blocks the enzyme splitting complex carbohydrates.
Is that the same as acarbose?
The mechanism matches. The strength and the legal status do not.
Do mulberry fruits contain it?
No. The fruit is a fruit; DNJ sits in the leaf.
Other Ingredients In The Blend
The label lists ingredients heaviest first, so position is the only quantitative information it carries.
