Top 10 Silymarin Suppliers, Manufacturers, Wholesalers, and Traders in Slovenia

Nestled in the Julian Alps, AlpineHerb Extracts has been a cornerstone of Slovenia's botanical extract industry since 1998. What started as a small family operation has grown into a leading manufacturer specializing in milk thistle extract and silymarin. Their secret? A deep connection to local farmers who grow organic milk thistle in the nutrient-rich soil of the Alpine valleys. AlpineHerb prides itself on cold-press extraction methods that preserve silymarin's potency, with purity levels consistently testing above 80%—a benchmark that has earned them partnerships with pharmaceutical companies across Europe.

Beyond their commitment to quality, AlpineHerb is a go-to for bulk botanical extracts, offering flexible wholesale options for businesses of all sizes. Whether you need 5kg for a small supplement line or 500kg for industrial production, their state-of-the-art facility can scale to meet demand. Certifications like ISO 9001 and GMP (Good Manufacturing Practice) underscore their dedication to safety, and their in-house lab conducts rigorous testing for heavy metals, pesticides, and microbial contaminants. What truly sets them apart, though, is their transparency: they're happy to share farm visit schedules and extraction process videos with clients, building trust that goes beyond a transaction.

For businesses looking for a one-stop shop for all things botanical, SloveniaBotanicals Trading is hard to beat. Founded in 2005, this Ljubljana-based company wears many hats: manufacturer, wholesaler, and trader of a wide range of extracts, with silymarin being their flagship product. Unlike some suppliers that focus solely on production, SloveniaBotanicals has built a global network of partners, allowing them to source raw milk thistle from the best regions (including Slovenia's own Karst Plateau) and distribute silymarin to over 30 countries.

Their silymarin offerings cater to diverse needs: pharmaceutical-grade extracts with 95% silymarin content for drug formulations, food-grade options for health supplements, and even cosmetic-grade variants for skincare products (think anti-aging serums and liver detox creams). As a bulk botanical extracts specialist, they offer competitive pricing for large orders, often with discounts for repeat clients. Their customer service team, fluent in English, German, and Italian, is known for responsiveness—whether you need help with customs documentation or advice on dosage formulations. Plus, their commitment to sustainability is evident in their carbon-neutral shipping practices and biodegradable packaging, making them a favorite among eco-conscious brands.

When precision is non-negotiable, SilymarinPro Slovenia delivers. Established in 2010, this Maribor-based manufacturer has carved a niche in producing ultra-high-purity silymarin, with some batches reaching 98% concentration—ideal for research labs and pharmaceutical companies working on innovative liver treatments. Their facility, equipped with supercritical CO2 extraction technology, ensures that silymarin is extracted without the use of harsh solvents, resulting in a cleaner, more bioavailable product.

What makes SilymarinPro stand out is their focus on research and development. They collaborate with the University of Ljubljana's Faculty of Pharmacy to study silymarin's potential beyond liver health, exploring applications in skincare and metabolic support. For clients with unique needs, they offer custom extraction services, adjusting parameters like particle size and solubility to match specific formulations. As a botanical extracts manufacturer, they also provide detailed Certificates of Analysis (CoA) for every batch, including HPLC test results and shelf-life data. While their prices are slightly higher than some competitors, the investment in quality pays off for businesses prioritizing efficacy and regulatory compliance.

For small to medium-sized businesses looking to balance quality and affordability, GreenValley Wholesalers is a trusted name. Operating out of Celje since 2003, this family-owned wholesaler sources silymarin from a network of vetted Slovenian manufacturers, curating a selection of milk thistle extract products that meet both organic and conventional standards. Their sweet spot? Bulk orders of 25kg to 200kg, with quick turnaround times (typically 3–5 business days for in-stock items).

GreenValley's appeal lies in their hands-on approach. They work closely with clients to understand their needs, whether it's a first-time buyer needing guidance on silymarin specifications or a seasoned brand looking to optimize costs. They offer both powdered and liquid silymarin extracts, and their product line includes standardized options (like 80% silymarin) as well as custom blends with other botanicals, such as artichoke or dandelion for liver support formulas. While they don't manufacture in-house, their strict supplier vetting process—including annual audits of partner facilities—ensures that every batch meets EU safety standards. Their low minimum order quantities (MOQs) also make them a great choice for startups testing new product lines.

Organic certification is a must for many brands today, and BioSily Slovenia has made it their mission to lead in this space. Founded in 2012, this supplier specializes in organic milk thistle extract, with silymarin derived from milk thistle grown on certified organic farms in Slovenia's Dolenjska region. Their products are certified by the European Organic Label (EU Organic) and the Soil Association, ensuring that no synthetic fertilizers, pesticides, or GMOs are used in the growing or extraction process.

BioSily's extraction facility, powered by renewable energy, uses water-based methods to produce silymarin that's not only organic but also free from residual solvents. Their product range includes organic silymarin powder (with purity levels from 60% to 85%) and organic milk thistle seed oil, rich in essential fatty acids. What resonates with clients is their storytelling—they regularly share profiles of the farmers they work with, highlighting sustainable practices like crop rotation and beekeeping that support local ecosystems. For brands focused on clean labels and ethical sourcing, BioSily's transparency and commitment to organic integrity make them a standout partner.

Innovation is the name of the game at TechExtract Manufacturing, a modern facility in Koper that combines traditional herbal knowledge with cutting-edge technology. Founded in 2015, TechExtract has quickly made a name for itself with its advanced supercritical fluid extraction (SFE) process, which uses CO2 to extract silymarin at lower temperatures, preserving its bioactive compounds better than traditional solvent-based methods. The result? Silymarin with enhanced stability and higher bioavailability, making it a favorite among nutraceutical brands looking to boost product efficacy.

TechExtract's focus on R&D is evident in their product offerings, which include microencapsulated silymarin—a form that's easier to incorporate into tablets, capsules, and even functional foods like energy bars. They also specialize in custom formulations, working with clients to develop silymarin blends tailored to specific health claims, such as liver detox or antioxidant support. With a production capacity of over 5000kg of silymarin per month, they're well-equipped to handle large-scale orders, and their ISO 22000 certification ensures food safety across all stages of production. For businesses that value innovation and scalability, TechExtract is a forward-thinking choice.

PureSily Labs' products are used in clinical trials and drug development, and their batch-to-batch consistency is unmatched—each lot comes with a comprehensive analytical report detailing silymarin content, isomer distribution, and impurity profiles. They also offer custom purification services for clients with specific research needs, such as isolating rare silymarin derivatives. While their minimum order quantities are higher (typically 10kg), and lead times longer (due to the meticulous purification process), the quality and reliability make them indispensable for high-stakes applications. If your work demands the purest silymarin available, PureSily Labs delivers.

Sustainability isn't just a buzzword for EcoExtracts Slovenia—it's the core of their business model. Founded in 2017 in Novo Mesto, this manufacturer has built a zero-waste facility that transforms every part of the milk thistle plant: the seeds are used for silymarin extraction, the stems and leaves become compost for local farms, and even the extraction byproducts are repurposed as animal feed. This circular approach has earned them recognition from the Slovenian Ministry of Environment and a loyal client base of eco-conscious brands.

EcoExtracts' silymarin products are available in both organic and conventional varieties, with purity levels ranging from 70% to 85%. They specialize in bulk powder extracts, but also offer liquid concentrates for skincare and beverage applications. What sets them apart is their commitment to fair trade—they pay farmers a premium for organic milk thistle, ensuring that the benefits of sustainable farming flow back to the community. For brands looking to align with ESG (Environmental, Social, Governance) goals, EcoExtracts offers a compelling story of sustainability and responsibility, backed by third-party certifications like the EU Ecolabel.

Last but certainly not least, Heritage Herbs Manufacturing brings a wealth of traditional knowledge to modern silymarin production. Founded in 1985, this is one of Slovenia's oldest botanical extract manufacturers, with roots in the country's herbalist traditions. Their approach blends time-tested extraction methods (like slow maceration) with modern quality control, resulting in silymarin that's both potent and steeped in heritage.

Heritage Herbs specializes in small-batch, artisanal silymarin, making them a favorite among boutique supplement brands and herbalists. Their flagship product is a slow-extracted milk thistle extract with a rich, earthy flavor, ideal for liquid supplements and tinctures. They also offer custom small-batch runs (as low as 1kg) for clients testing new formulations, with personalized support from their team of herbal experts. While their production capacity is smaller than some competitors, their attention to detail and commitment to tradition make them a unique choice for brands that value craftsmanship and storytelling.
