Milk thistle extract powder is a botanical ingredient sourced from Silybum marianum, standardized mainly for silymarin, a group of flavonolignans known for their well-studied antioxidant properties. As a trusted plant extract manufacturer, we offer stable quality with controlled impurity levels and consistent active content.
Compared with common market alternatives, our Silybum Marianum extract is produced under strict solvent control and multi-step purification, ensuring reliable silymarin consistency from batch to batch. Each batch is tested for identity, purity, heavy metals, residual solvents, and microbiology, making it suitable for dietary supplements, herbal formulas, food products, and other applications requiring high-quality botanical actives.
We have been dedicated to the plant extract industry for 15 years, continuously upgrading our production lines and maintaining an in-house testing laboratory to ensure full compliance for export. We offer a comprehensive range of specifications and ship directly from the factory, eliminating middlemen; furthermore, our US-based subsidiary and overseas warehouse allow us to significantly reduce shipping times for North American customers.

Detoxification: It aids the body's natural detox pathways, making it a perfect ingredient for "cleanse" and "detox" formulations.
Metabolic Health: Emerging research suggests milk thistle may support healthy blood sugar levels and cholesterol balance, broadening its appeal beyond just liver health.

FAQ
Q1: What is the difference between UV and HPLC testing methods for Silymarin?
This is a common question. UV (Ultraviolet) testing usually shows a higher percentage (e.g., 80%) because it measures the total group of flavonolignans and some related phenols. HPLC (High-Performance Liquid Chromatography) is more specific and separates the individual compounds (like Silybin A and B). Typically, an 80% UV spec corresponds to roughly 50-60% by HPLC. We provide both specs based on your needs.
Q2: Is your product solvent-free?
We offer different extraction methods. Our standard Silymarin Powder is extracted using food-grade Ethanol or Acetone, followed by a rigorous removal process. The final product has residual solvents far below safety limits (usually <5000ppm or stricter upon request), making it safe for consumption.
Q3: Can you guarantee low PAHs for the European market?
Yes. We understand the strict EU regulations regarding PAHs. We have a specialized purification process to remove these contaminants, ensuring our extract meets the strict European Pharmacopoeia standards for export.
Q4: What is the Minimum Order Quantity (MOQ) for bulk orders?
Our standard MOQ is 25kg (one standard drum). However, we are happy to provide smaller sample quantities for your R&D and pilot testing.
Q5: How do I store the extract to maintain potency?
It is relatively stable, but it should be stored in a cool, dry place away from direct sunlight and heat. Keep the drum tightly sealed. Under these conditions, the shelf life is typically 24 to 36 months.
