Introduction

Mulberry Leaf Extract is derived from the leaves of Morus alba, a tree native to China and widely cultivated in Asia, Europe, and North America. Traditionally, mulberry leaves have been used in Chinese medicine for supporting blood sugar regulation, liver health, and overall vitality. They are also consumed as mulberry leaf tea for wellness and longevity.

The key bioactive compound, 1-Deoxynojirimycin (DNJ), acts as a natural α-glucosidase inhibitor, slowing down carbohydrate digestion and glucose absorption. This mechanism helps maintain healthy blood sugar levels, making mulberry leaf extract highly valued in metabolic health and weight management formulations. Additionally, mulberry leaves contain flavonoids, alkaloids, and polyphenols that contribute antioxidant and anti-inflammatory benefits.

Commercial production involves harvesting fresh mulberry leaves, drying, and extracting with water or ethanol, followed by purification and spray-drying. The resulting product is a fine green to brown powder, soluble in water, stable under dry storage, and widely applied in nutraceuticals, functional teas, and metabolic support formulations.

Product Processing

Standard and Certificates 

All of our products are made in a GMP-compliant facility where every step of production is carefully managed. Over the years, our factory has passed several well-recognized audits, including HACCP, ISO22000 and ISO9001. The products also meet Kosher and Halal requirements, and we hold FDA registration as well. These certifications reflect the standards we follow rather than just labels we collect—they’re part of how we ensure consistency and safety in every batch. 


Free Sample Available 

If you’d like to get a feel for the product before placing an order, we can send you a free sample. In most cases, we provide around 10–20 grams so you can evaluate the quality yourself. For items with higher raw material costs, we will confirm the exact amount we can offer so everything is clear before shipping. 


Standard Packaging and Private Label 

For regular shipments, we usually pack goods in 1–5 kg aluminum foil bags, 10–20 kg cartons, or 10–30 kg fiber drums, depending on the item and order size. 
If you’re planning to sell under your own brand, we also handle private labeling. We can help design and produce packaging with your logo or artwork so the products arrive ready for retail. Many customers find this saves them a lot of time compared with printing and repacking on their end. 

Shipping Method 

Orders under one metric ton are generally shipped through major express couriers such as DHL, FedEx, UPS or EMS. For larger quantities, we can arrange transport by sea or railway. The best method depends on your location and how quickly you need the goods, so we’ll help you choose the most practical option. 


After Sale Services 

Most of our products remain stable for up to two years, and we guarantee their quality within that period. If anything arrives below your expectations, our return process is straightforward. You can send back the portion in question, and we will refund the corresponding amount—no complicated procedures or hidden conditions.
