Mulberry Leaf Extract with High DNJ and Mulberroside A Content
At Botanical Cube Inc., our Mulberry Leaf Extract (also known as Morus alba leaf extract or White Mulberry Leaf Powder) is crafted to deliver consistent quality and targeted efficacy. Rich in 1-deoxynojirimycin (DNJ) and Mulberroside A, this extract supports blood sugar management, antioxidant benefits, and overall wellness, making it an essential ingredient for functional beverages, dietary supplements, and nutraceutical formulations.
In the current global market, demand for mulberry leaf-derived products is growing rapidly due to their natural health-promoting properties. What sets our extract apart is the precision-controlled cultivation and extraction process in our own production facilities, ensuring higher purity, reliable bioactive content, and batch-to-batch consistency that few suppliers can match.
Our OEM and private label capabilities allow brands to customize formulations, concentrations, and packaging to suit their product lines, giving partners flexibility and speed to market. By combining our in-house extraction technology with full regulatory certifications, including ISO22000, USDA Organic, Halal, and Kosher, we provide not just a raw material, but a ready-to-integrate solution that meets the needs of modern health-conscious
consumers.
Why Our Mulberry Leaf Extract?
1. High Bioactive Content
Standardized to 1–10% DNJ and 2–10% Mulberroside A, ensuring consistent efficacy for blood sugar support and antioxidant formulations. Most competitors only provide 0.5–2% DNJ, giving our clients a measurable advantage.
2. Controlled Cultivation & Extraction
Sourced from our own mulberry plantations with traceable farming practices, achieving >98% batch-to-batch purity, reducing variability for large-scale production.
3. Scalable Supply
Production capacity supports orders from 1 kg to 25,000 kg, allowing reliable sourcing for small to large-scale manufacturers without supply interruptions.

Key Production and Formulation Considerations
1. Moisture Sensitivity
Protect from humidity to prevent clumping and degradation of active compounds.
2. Temperature & Light Sensitivity
Avoid high heat during processing; UV light may reduce antioxidant activity.
3. Particle Size
Fine, uniform powder improves solubility in beverages and uniform distribution in powders or bars.
4. pH Compatibility
Best in neutral to slightly acidic formulations; extreme pH may reduce solubility or stability.
5. Flavor Masking
Natural bitterness requires consideration in sweetened or flavored products.
6. Regulatory & Certification
Ensure supplier provides organic, non-GMO, heavy metals-tested, and microbiologically safe extract for consumer confidence.
7. Compatibility with Other Ingredients
Works well with fibers, proteins, and herbal blends but always check for sedimentation or precipitation in liquids.
Common Applications of Mulberry Leaf Extract
1. Blood Sugar Management Supplements
Frequently used in capsules, tablets, or powders targeting glucose control and metabolic health due to its 1-Deoxynojirimycin (DNJ) content.
2. Weight Management & Functional Foods
Incorporated into meal replacement powders, functional drinks, and snack bars to support carbohydrate metabolism.
3. Beverages & Ready-to-Drink Formulations
Added to teas, juices, or functional drinks for its antioxidant properties and mild bitter flavor that blends well with fruit or herbal notes.
4. Nutraceuticals & Dietary Supplements
Used in combination with other botanical ingredients such as cinnamon, bitter melon, or green tea for synergistic effects on blood sugar and metabolic support.
5. Clinical and Elderly Nutrition Products
Preferred in products where gentle, plant-based glucose support is required due to its natural origin and low allergenicity.
Recommended Dosage
1. Capsules/Tablets: 100–300 mg per serving, depending on standardization (DNJ content).
2. Powders & Functional Drinks: 0.5–2% of formula weight, depending on taste and solubility requirements.
3. Snacks & Bars: 1–3% of formulation, blended with fibers or protein to improve texture and mouthfeel.
Note: Final dosage may vary depending on desired functional claims, target market, and combination with other ingredients.
FAQs
1. Does mulberry leaf extract taste bitter?
Natural mulberry leaf extract can have a mild bitter or grassy note.Blend with natural sweeteners, fruit flavors, or other botanicals to mask bitterness while maintaining clean-label positioning.
2. Is it suitable for diabetic consumers?
Yes, but formulation must consider overall sugar content in the product.Pair with low-calorie carriers and avoid adding high-sugar ingredients in functional beverages or bars.
3. How stable is the extract in beverages or powders?
It can degrade under high temperature, light, or humidity.Use encapsulation or airtight packaging, store under cool and dry conditions, and test stability during product development.
4. Is it safe to combine with other botanical extracts?
Generally yes, but interactions may affect taste or solubility.Conduct small-scale trials to check flavor, pH stability, and sedimentation before scaling up.
5. How do I standardize DNJ content?
DNJ levels can vary by supplier and extraction method.Choose suppliers providing batch-to-batch standardized DNJ testing, ideally with HPLC certificates of analysis.
