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

1. Nordic Milk Thistle Extracts AS

Founded in 2008, Nordic Milk Thistle Extracts AS has grown from a small family-run operation to one of Norway's leading manufacturers of silymarin and milk thistle extracts. Based in Drammen, just outside Oslo, the company prides itself on vertical integration: they source organic milk thistle seeds directly from farms in southern Norway and northern Denmark, ensuring full traceability from field to finished product. "We believe the best silymarin starts with the best raw materials," says CEO Lars Eriksen. "Our farmers follow strict organic practices, avoiding pesticides and synthetic fertilizers, which means our extracts have naturally higher silymarin concentrations—often 70-80%—without harsh chemical extraction."

Their product line includes bulk silymarin powder (available in 1kg to 25kg bags), standardized milk thistle extract capsules for private labeling, and liquid extracts for cosmetic use. What sets them apart, however, is their commitment to sustainability. The company runs on 100% renewable energy, and their extraction process uses 30% less water than industry averages. They also offer carbon-neutral shipping for bulk orders within Norway, a hit with eco-conscious brands.

• Organic Focus: EU Organic certified, with seeds traceable to individual farms.
Bulk Flexibility: Minimum orders start at 1kg for small businesses, scaling up to 1-tonne pallets for large manufacturers. Quality Control: In-house lab testing for silymarin content, heavy metals, and microbial purity before every shipment.

2. Oslo Botanical Solutions

For businesses needing pharmaceutical-grade precision, Oslo Botanical Solutions is a name that comes up time and again. Established in 2012, this supplier and trader specializes in high-purity silymarin extracts tailored for the pharmaceutical, nutraceutical, and cosmetic industries. Unlike many suppliers, they don't manufacture in-house but instead partner with GMP-certified facilities in Germany and Poland, curating a portfolio of extracts that meet the strictest European Pharmacopoeia (Ph. Eur.) standards.

"Our niche is consistency," explains product manager Ingrid Hansen. "We work with labs to standardize silymarin content to exactly 80% or 90%, with minimal variability between batches. For pharmaceutical companies formulating liver medications, that level of precision is non-negotiable." Their offerings include both powdered and liquid silymarin extracts, with options for water-soluble or oil-soluble formulations—ideal for skincare brands looking to incorporate silymarin into serums or creams.

Oslo Botanical Solutions also stands out for its global reach. While based in Oslo, they import raw materials from trusted suppliers in Italy (a top milk thistle-growing region) and offer door-to-door delivery across Norway, with most orders arriving within 48 hours. Their customer service team includes a certified herbalist who can advise on formulation best practices, a bonus for new businesses navigating ingredient selection.

• Pharmaceutical Grade: Meets Ph. Eur. and USP standards for purity and potency.
Custom Formulations: Can adjust solubility and particle size for specific applications (e.g., tablets vs. skincare). Fast Turnaround: Local warehousing in Oslo ensures quick delivery for urgent orders.

3. Bergen Natural Ingredients

Nestled in Norway's southwest coast, Bergen Natural Ingredients has built a loyal following among organic food and supplement brands since 2010. As a wholesaler, they focus on bulk botanical extracts, with silymarin being one of their flagship products. What makes them unique? Their commitment to "whole-plant" extraction, which preserves not just silymarin but also other beneficial compounds in milk thistle, such as flavonolignans and fatty acids.

"Many suppliers isolate silymarin to the exclusion of other nutrients, but we believe the whole plant works better," says founder Ole Pettersen. "Our extracts are made using a gentle ethanol extraction process that captures the full spectrum of milk thistle's benefits, making them popular for wellness supplements and herbal teas." Their bulk silymarin powder is available in 25kg drums, with organic certification from Ecocert and the Non-GMO Project Verified seal—key selling points for brands targeting health-conscious consumers.

Bergen Natural Ingredients also offers competitive pricing for large orders, with discounts starting at 500kg. They've recently expanded into private labeling, allowing small businesses to brand their silymarin capsules with minimal upfront investment. For clients new to silymarin, their team provides free sample kits (including COAs and safety data sheets) to test before committing to a bulk purchase.

• Full-Spectrum Extracts: Preserves additional beneficial compounds in milk thistle.
Organic Credentials: Ecocert and Non-GMO Project Verified, appealing to clean-label brands. Small-Business Friendly: Private labeling options with low minimums (500 units).

4. Trondheim Pharma Extracts

When it comes to high-purity silymarin, Trondheim Pharma Extracts is a heavyweight. This manufacturer, founded in 2005, specializes in extracts for the pharmaceutical and research sectors, where even the smallest impurity can derail a project. Their state-of-the-art facility in Trondheim is FDA registered and cGMP compliant, with extraction processes that yield silymarin concentrations up to 95%—among the highest in the industry.

"We cater to clients who need more than just 'pure'—they need 'analytically pure,'" says head of R&D Dr. Sofie Larsen. "Our silymarin undergoes HPLC and mass spectrometry testing to ensure every batch meets our 95% purity benchmark, and we provide detailed certificates of analysis (COAs) with every order." Their product line includes both standard silymarin (for supplements) and ultra-pure silymarin (for lab research), with options for custom packaging (amber glass vials for light-sensitive applications, for example).

While their focus is on high-end markets, Trondheim Pharma Extracts also offers technical support, including method development for clients testing silymarin in their own labs. They've partnered with several Norwegian universities on liver health research, further solidifying their reputation as a trusted supplier for scientific applications.

• Ultra-High Purity: Silymarin concentrations up to 95%, ideal for research and pharmaceuticals.
Stringent Testing: HPLC and mass spectrometry verification with detailed COAs. Academic Partnerships: Collaborates with universities, ensuring cutting-edge extraction techniques.

5. Stavanger Bulk Botanicals

Stavanger Bulk Botanicals has carved a niche as Norway's go-to wholesaler for organic and sustainably sourced botanical extracts. Founded in 2015 by a group of environmental scientists, the company prioritizes ethical sourcing, working directly with farmer cooperatives in Greece and Spain to ensure fair wages and eco-friendly farming practices. Their silymarin offerings include both conventional and organic milk thistle extract, with a focus on bulk quantities for large-scale manufacturers.

"We believe sustainability shouldn't cost more," says sustainability director Lise Andersen. "By cutting out middlemen and working directly with farmers, we're able to offer organic silymarin at prices competitive with conventional extracts." Their bulk options range from 50kg sacks to 1-tonne pallets, with discounts for annual contracts. They also offer "green packaging"—recyclable or biodegradable drums and bags—for clients looking to reduce their environmental footprint.

Stavanger Bulk Botanicals has gained traction with supplement brands in the Nordic region for their transparency: they publish annual sustainability reports detailing their sourcing practices and carbon footprint. For businesses targeting the eco-conscious Norwegian market, this level of accountability is a powerful marketing tool.

• Sustainable Sourcing: Direct partnerships with farmer cooperatives for ethical, eco-friendly ingredients.
Competitive Organic Pricing: Bulk organic silymarin at prices comparable to conventional alternatives. Eco-Friendly Packaging: Recyclable/biodegradable options for bulk orders.

6. Oslo Health Ingredients

While many suppliers focus on supplements and pharmaceuticals, Oslo Health Ingredients has made a name for itself in the cosmetic industry, offering silymarin extracts tailored for skincare and haircare products. Since 2014, they've worked with beauty brands across Norway to create formulations that leverage silymarin's antioxidant and anti-inflammatory properties, which are said to soothe sensitive skin and protect against environmental damage.

"Cosmetic formulators have unique needs," explains cosmetic chemist and founder Karoline Nilsen. "They need extracts that are stable in emulsions, compatible with other ingredients like hyaluronic acid, and have a neutral scent. Our silymarin is microencapsulated to improve stability, ensuring it stays effective in serums and creams for up to 24 months." Their product line includes silymarin in powder, liquid, and oil-soluble forms, with a "cosmetic grade" option that's been tested for skin irritation (non-irritating, per EU Cosmetics Regulation 1223/2009).

Oslo Health Ingredients also offers small-batch sampling—starting at 100g—so brands can test formulations before scaling up. They've even developed a ready-to-use silymarin serum base, saving time for businesses without in-house formulation teams. With clients ranging from indie skincare startups to large Norwegian beauty chains, they've become a trusted partner in the cosmetic ingredient space.

• Cosmetic-Grade Focus: Microencapsulated silymarin for stability in skincare products.
Skin Safety Testing: Certified non-irritating, compliant with EU cosmetic regulations. Small-Batch Sampling: Low minimum orders for product development and testing.

7. Bergen Pharma Logistics

For businesses needing access to global silymarin sources, Bergen Pharma Logistics acts as a bridge between international manufacturers and the Norwegian market. As a trader, they don't produce extracts themselves but instead vet and partner with top-tier suppliers in countries like India, China, and Italy, curating a portfolio of high-quality silymarin products. This global network allows them to offer a wider range of price points and certifications than many local suppliers.

"Norway is a small market, so we saw a need to connect local businesses with global expertise," says logistics director Erik Johansen. "For example, we work with a GMP-certified manufacturer in India that specializes in low-cost, high-volume silymarin, perfect for budget-conscious brands. For clients needing organic extracts, we source from Italy, where milk thistle is grown in nutrient-rich soil." They handle all import logistics, including customs clearance and documentation, making it easy for Norwegian businesses to access international ingredients without the hassle of cross-border shipping.

Bergen Pharma Logistics also offers "mix and match" bulk orders, allowing clients to combine silymarin with other botanical extracts (like green tea or turmeric) in a single shipment, reducing shipping costs. Their customer portal provides real-time tracking for international orders, so clients always know when to expect their delivery.

• Global Network: Partners with top manufacturers worldwide for diverse pricing and certification options.
Import Expertise: Handles customs, documentation, and logistics for seamless international sourcing. Mix-and-Match Orders: Combine silymarin with other extracts to optimize shipping costs.

8. Tromsø Natural Extracts

Located in Norway's northernmost city, Tromsø Natural Extracts embraces the "slow extract" movement, producing small-batch, artisanal silymarin extracts using traditional methods. Founded in 2017 by herbalist and ethnobotanist Anna Sørensen, the company prioritizes quality over quantity, using cold maceration to extract silymarin from organic milk thistle seeds sourced from Norway's own coastal farms.

"Cold maceration preserves heat-sensitive compounds that can be destroyed in industrial extraction processes," Sørensen explains. "The result is a richer, more bioavailable extract that our clients—mostly small wellness brands and herbalists—swear by." Their silymarin powder is sold in small batches (up to 50kg per run) and is certified organic by the Norwegian Organic Association (KRAV), a rigorous certification that ensures compliance with strict environmental and animal welfare standards.

Tromsø Natural Extracts has built a cult following among holistic health practitioners in Norway, who value the company's transparency: clients can visit the extraction facility in Tromsø for tours, and each batch is labeled with the farm where the milk thistle was grown. For businesses looking to tell a "local story" with their products, this level of connection to the land is invaluable.

• Artisanal Extraction: Cold maceration for heat-sensitive compound preservation.
Local Sourcing: Organic milk thistle seeds from Norwegian coastal farms. Small-Batch Quality: Limited runs ensure freshness and attention to detail.

9. Kristiansand Bulk Herbs

For businesses that prefer to process their own extracts, Kristiansand Bulk Herbs offers a different approach: they supply raw milk thistle seeds and crude silymarin extract, allowing clients to control the final extraction process. Founded in 2005, this wholesaler sources seeds from organic farms in France and Hungary, known for their high silymarin content, and sells them in bulk quantities (25kg sacks to 1-tonne pallets) at competitive prices.

"Many of our clients are larger manufacturers with their own extraction facilities," says sales manager Per Olsen. "They want to cut costs by processing raw seeds in-house, and we provide the highest-quality starting material." In addition to raw seeds, they offer crude silymarin extract (30-40% purity), a cost-effective option for businesses that want to refine the extract further to higher concentrations.

Kristiansand Bulk Herbs also provides technical support, including guidance on extraction methods (ethanol vs. supercritical CO2) and seed storage best practices to maintain silymarin potency. For new manufacturers, this expertise can save time and reduce waste during the production process.

• Raw Material Focus: Bulk milk thistle seeds and crude extract for in-house processing.
Cost-Effective: Lower price point for businesses with their own extraction capabilities. Technical Guidance: Expert advice on extraction methods and seed storage.

10. Ålesund Botanical Traders

Rounding out our list is Ålesund Botanical Traders, a supplier and trader known for its specialty silymarin blends and custom formulation services. Since 2016, they've worked with clients to create unique extracts tailored to specific needs—whether a high-silymarin blend for liver supplements or a silymarin-curcumin combination for anti-inflammatory products.

"One-size-fits-all extracts don't work for everyone," says founder Martin Halvorsen. "A sports nutrition brand might want a fast-absorbing silymarin powder, while a herbal tea company might prefer a water-soluble liquid. We blend and formulate to order." Their custom services include adjusting particle size, adding flow agents for better compressibility in tablets, or combining silymarin with other botanicals like artichoke or dandelion for synergistic effects.

Ålesund Botanical Traders also caters to the food and beverage industry, offering silymarin extracts approved for use in functional foods like energy bars and herbal drinks. With certifications including Kosher, Halal, and ISO 22000 (food safety), they're a versatile option for businesses outside the supplement and cosmetic spaces.

• Custom Formulations: Blends and tailored extracts for specific applications.
Food-Grade Options: Silymarin extracts approved for functional foods and beverages. Synergistic Blends: Combines silymarin with other botanicals for enhanced benefits.
