Mulberry Leaf Extract DNJ 10% (1-Deoxynojirimycin) — Natural Alpha-Glucosidase Inhibitor
What Is Mulberry Leaf Extract DNJ 10%?

Mulberry leaf has a long history in traditional use, but modern science has zeroed in on one well-characterized compound: 1-Deoxynojirimycin, or DNJ. Our extract is derived from Morus alba L. leaves and standardized to a minimum of 10.0% DNJ (CAS 19130-96-2), tested by HPLC — a more specific and rigorous method than the industry default.

The product is a brown, fine powder with mild herbaceous notes and dependable dispersibility. This is not a generic mulberry leaf powder with an unspecified active fraction. It is a quantified, potency-guaranteed natural alpha-glucosidase inhibitor ingredient — and for formulators working in blood sugar and carb management, that distinction matters.

How DNJ Works

Targeted enzyme inhibition — DNJ acts at the intestinal brush border, inhibiting alpha-glucosidase enzymes that break complex sugars into absorbable glucose. The result is a slower, more gradual release of glucose into the bloodstream after a carbohydrate-containing meal.
Complementary to amylase blockers — Where phaseolamin targets starch breakdown early in digestion, DNJ works further downstream. Together they offer broader carb coverage.
Mechanism-driven, not stimulant-based — No stimulants, no appetite suppression trickery — just a clearly understood enzymatic mechanism that fits cleanly into evidence-based formulas.
Application Areas

Blood sugar support supplements — standalone DNJ capsules and glucose-management complexes alongside cinnamon polyphenols, chromium, or berberine.
Carb management formulas — stimulant-free stacks combining alpha-glucosidase and alpha-amylase inhibition for full-spectrum carb blocking.
Functional foods and beverages — RTD teas, meal replacement shakes, and powdered drink mixes where a water-dispersible DNJ functional food ingredient adds genuine value.
Wellness gummies and soft chews — consumer-friendly formats that make the mulberry leaf extract blood sugar ingredient concept approachable for everyday retail.
Why a Bulk Mulberry Leaf Extract Powder Factory?

Shaanxi Huaze Biotechnology Co., Ltd. is not a reseller. We extract Morus alba L. leaves in-house at our 25,000 m² Yangling facility, operating under ISO 9001-certified quality management with Kosher and Halal certification. Every DNJ 10% batch is tested by HPLC against full enterprise specifications — identity, assay, appearance, microbials, heavy metals — before release. If a batch does not pass, it does not ship. As a mulberry leaf extract manufacturer with direct control over sourcing and production, we offer consistent potency, full lot traceability, and a supply chain with zero middlemen.
