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

Founded in 2005, Maple Leaf Botanicals has grown from a small family-owned operation to one of Canada's most trusted botanical extracts manufacturers. Based in Toronto, this company specializes in producing high-quality silymarin from locally sourced milk thistle, ensuring freshness and traceability. As both a manufacturer and wholesaler, they cater to businesses of all sizes—from startups to large supplement brands—offering bulk quantities starting at 10kg.

What sets Maple Leaf apart is its commitment to sustainability. Their extraction facility uses eco-friendly solvents and energy-efficient processes, reducing environmental impact without compromising on quality. All silymarin products are certified organic by Pro-Cert Organic Systems and adhere to GMP and ISO 9001 standards, giving customers peace of mind. Beyond silymarin, they also produce a range of botanical extracts, making them a one-stop shop for brands needing diverse ingredients.

Customers praise their responsive customer service and transparent sourcing practices. "We've worked with Maple Leaf for three years, and their silymarin consistently tests above industry purity standards," notes a local supplement brand owner. "Their team even shares farm visit reports, so we know exactly where our ingredients come from."

Nestled in Vancouver's thriving wellness hub, Pacific Extracts Inc. has built a reputation as a go-to supplier for high-purity silymarin. With a focus on pharmaceutical and nutraceutical industries, they specialize in silymarin extracts with concentrations ranging from 60% to 85%, tailored to meet strict industry requirements. As a supplier and exporter, they serve clients across Canada and internationally, including the U.S., Europe, and Asia.

Pacific Extracts prides itself on its state-of-the-art testing lab, where every batch of silymarin undergoes rigorous analysis for potency, heavy metals, and contaminants. Their certifications—including Non-GMO Project Verified, Kosher, and Halal—make them a versatile choice for brands with specific dietary or religious requirements. Minimum orders start at 5kg, but they offer discounted pricing for bulk purchases (100kg+), appealing to large-scale manufacturers.

One unique offering is their "Custom Purity Program," which allows clients to request silymarin with exact specifications (e.g., 70% silybin, the active component of silymarin). "We needed a very specific silymarin profile for our liver support supplement, and Pacific Extracts delivered exactly what we asked for," says a pharmaceutical company representative. "Their technical team was incredibly helpful in guiding us through the process."

Northern Botanicals Ltd., based in Montreal, is a manufacturer and custom formulator that bridges the gap between raw ingredients and finished products. While they excel in silymarin production, their real strength lies in creating tailored solutions for clients—whether it's a pre-mixed supplement powder, a liquid extract for skincare, or a encapsulated formula for easy integration into products. This flexibility has made them a favorite among small to mid-sized businesses.

Certified organic by Ecocert and Fair Trade, Northern Botanicals sources milk thistle from sustainable farms in Quebec and Ontario, supporting local agriculture. Their GMP-certified facility ensures compliance with health Canada's strict manufacturing standards, and they offer private-label services for brands looking to launch their own silymarin-based products. Minimum orders for bulk silymarin start at 25kg, but custom formulation projects can have lower minimums depending on the scope.

Clients rave about their collaborative approach. "We wanted to create a silymarin-infused face serum, and Northern Botanicals helped us develop the perfect extract consistency—lightweight, stable, and effective," shares a Montreal-based skincare brand owner. "They even provided sample batches for testing before we committed to a full order."

For businesses in need of large quantities of silymarin, Alberta Natural Ingredients in Calgary is a top choice.

Based in Halifax, they source milk thistle directly from family farms in Nova Scotia and Prince Edward Island, supporting local agriculture and reducing carbon footprints. This "farm-to-extract" model ensures freshness and allows them to offer organic, traceable silymarin to clients across Canada.

With minimum orders as low as 1kg, they're ideal for small businesses, herbalists, and artisans creating niche products like herbal teas, tinctures, or natural skincare. Their silymarin is available in powder, liquid, and encapsulated forms, and they offer custom packaging (e.g., 100g jars for retail) for clients looking to sell directly to consumers.

East Coast Extract Co. is certified organic by the Organic Federation of Canada and participates in the "1% for the Planet" initiative, donating 1% of sales to environmental nonprofits. "As a small herbal brand, we love that we can source silymarin locally and support farmers in our region," says a Halifax-based business owner.

Ontario Botanical Solutions (OBS) is more than a supplier—it's a research partner for businesses at the cutting edge of natural health. Based in Ottawa, this manufacturer collaborates with universities and research institutions to develop innovative silymarin-based ingredients, such as time-release silymarin for enhanced absorption or water-soluble extracts for beverage applications. Their focus on R&D makes them a leader in functional ingredients.

OBS produces pharmaceutical-grade silymarin that meets Health Canada's Good Manufacturing Practices (GMP) for pharmaceuticals, making it suitable for clinical trials and prescription products. They also offer sample sizes (500g) for testing, allowing clients to validate efficacy before scaling up. For larger orders (10kg+), they provide technical support to help integrate silymarin into complex formulations.

"We partnered with OBS to develop a silymarin supplement with improved bioavailability," explains a nutraceutical researcher. "Their team shared valuable data on absorption rates and helped us optimize our formula. The end result was a product that outperformed competitors in third-party tests."

This rapid turnaround is a game-changer for businesses with tight production schedules or unexpected stock shortages.

While they prioritize efficiency, quality isn't compromised. All silymarin is sourced from GMP-certified manufacturers and tested for purity upon arrival. Their ISO 14001 certification (environmental management) also reflects a commitment to reducing waste, with eco-friendly packaging options available. Minimum orders start at 20kg, but they offer "emergency small batches" (5kg) for urgent requests, albeit at a slight premium.

Quebec Botanical Traders is a trader and international supplier that connects Canadian businesses with global silymarin markets—and vice versa. With offices in Quebec City and partnerships in Europe, Asia, and South America, they specialize in importing high-quality silymarin (often from regions with ideal growing conditions for milk thistle) and exporting Canadian-made extracts to international buyers.

They offer a wide range of silymarin products, from raw powder to pre-formulated blends, and their multilingual team (fluent in English, French, Spanish, and Mandarin) simplifies cross-border transactions. Certifications vary by product but often include ISO 22000 and Halal, making them a strong choice for global brands.

Rounding out our list is West Coast Wellness Ingredients, a small-batch manufacturer in Victoria that prioritizes "clean" extracts. Their silymarin is produced without artificial solvents or preservatives, using cold-press extraction to retain maximum nutrients. This gentle process results in a milder-tasting extract, ideal for products like herbal teas or children's supplements where flavor matters.

Certified organic, vegan, and GMP-compliant, they cater to niche markets, including holistic health practitioners, small skincare brands, and specialty food companies. Minimum orders start at 1kg, and they offer personalized service—including sample testing and formulation advice—for clients new to working with silymarin.
