Description

Milk Thistle Extract is derived from the seeds of Silybum marianum, a flowering herb native to the Mediterranean region. For over 2,000 years, milk thistle has been used in European herbal medicine as a natural remedy for liver and gallbladder support. It remains one of the most widely researched and trusted botanical extracts for promoting hepatic health.

The extract is standardized to silymarin (≥80%), a complex of flavonolignans including silybin, silydianin, and silychristin. Silymarin is well known for its antioxidant, hepatoprotective, and detoxifying effects. Modern research suggests that Milk Thistle Extract supports liver function, helps protect against oxidative stress, promotes detoxification, and contributes to overall metabolic and digestive wellness.

Commercial production involves harvesting and cleaning of mature seeds, followed by ethanol extraction and purification. The resulting fine yellow-brown powder is stable under dry storage, soluble in ethanol, and partially soluble in water. Milk Thistle Extract is widely applied in liver health supplements, detox formulations, and functional wellness products.

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.
