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

Founded in 1998 in Zurich, Alpine Botanicals Ltd. has built a legacy around "pure extracts from the Swiss Alps." Specializing in high-potency botanical extracts, their silymarin offerings are a cornerstone of their product line. What sets them apart? A vertically integrated supply chain: they partner with local farmers to grow organic milk thistle, ensuring full control from seed to extract. Their silymarin is standardized to 80% flavonolignans (the active compounds in silymarin), with options for 95% purity for pharmaceutical clients.

Certifications matter here—Alpine Botanicals holds ISO 9001, GMP, and organic certifications from Ecocert, making them a favorite for brands prioritizing clean labels. They also offer bulk quantities (from 1kg to 1000kg+) and custom formulations, including water-soluble silymarin for beverages and skincare. With export markets spanning Europe, Asia, and North America, they're a trusted name for both small-scale supplement makers and large pharmaceutical companies.

Standout feature: In-house R&D lab for testing silymarin potency and stability, ensuring batch-to-batch consistency.

Headquartered in Basel, Swiss Extracts Group is a family-owned business with over 30 years in the botanical extract industry. While they produce a range of extracts, silymarin is their claim to fame—they're one of the few suppliers in Switzerland offering pharmacopoeial-grade silymarin , meeting the strict standards of the European Pharmacopoeia (Ph. Eur.). This makes them a top pick for pharmaceutical companies developing liver support medications.

Their production facility in Lausanne is equipped with supercritical CO2 extraction technology, which preserves silymarin's bioactivity without using harsh solvents. They source milk thistle seeds from sustainable farms in France and Germany (close enough to ensure freshness, but with the same rigorous quality checks as Swiss-grown crops). For wholesalers, they offer flexible bulk pricing, with minimum orders starting at 50kg. They also provide detailed COA (Certificate of Analysis) and MSDS documents, a must for regulatory compliance.

Standout feature: Custom encapsulation services for clients looking to skip the manufacturing step and receive ready-to-package silymarin capsules.

Nestled in the scenic town of Lucerne, Green Valley Botanicals has carved a niche in "sustainable silymarin for the modern market."

Their silymarin is available in both powder and liquid forms, with a focus on organic and wild-harvested milk thistle (though they also offer conventional options for cost-sensitive buyers).

What makes Green Valley a standout? Their commitment to transparency. They publish annual sustainability reports and allow clients to trace their silymarin batch back to the farm via a QR code system. Their standard silymarin powder is 80% pure, but they also offer a "premium line" with 90% purity, targeted at high-end supplement brands. Wholesalers appreciate their fast lead times—most bulk orders ship within 3–5 business days—and their dedicated customer service team, which provides support in English, German, and French.

Standout feature: A "sample program" for new clients, offering 100g trial sizes of silymarin to test potency and compatibility before committing to bulk orders.

Based in St. Gallen, Alpine Extracts & Co. is a newer player (founded in 2010) but has quickly made a name for itself with "innovation in every extract." Their silymarin line includes a unique "cold-pressed" option, which uses low-temperature extraction to preserve delicate compounds, resulting in a higher concentration of antioxidants. This cold-pressed silymarin is popular in natural skincare products, where its anti-aging properties (thanks to its ability to fight free radicals) are highly valued.

Certifications include GMP, organic (from the Swiss Organic Association), and Kosher, making them a versatile choice for diverse markets. They offer silymarin in powder, liquid, and even oil-soluble forms, with bulk sizes starting at 500g. What's unique?

Standout feature: A "price match guarantee" for bulk orders, ensuring clients get the best possible rate without sacrificing quality.

Founded in 2005, they specialize in extracts for the pharmaceutical and nutraceutical industries, with silymarin being their flagship product. Their silymarin is produced in a GMP-certified, FDA-registered facility, making it suitable for use in over-the-counter (OTC) medications and prescription drugs. They offer both standard silymarin (80% flavonolignans) and a high-purity version (95%) for clinical applications.

Nestled in the Swiss Alps near Interlaken, Mountain View Extracts lives up to its name by sourcing ingredients from "pristine mountain environments." Founded in 2012, they focus on organic and wild-harvested botanicals, with their silymarin coming from milk thistle grown at high altitudes (over 1,000 meters), which they claim has higher flavonolignan content due to the harsh growing conditions. Their silymarin is certified organic by both Ecocert and the USDA, making it a top choice for U.S.-based organic supplement brands.

Product offerings include silymarin powder, liquid extract, and even silymarin-infused oils for skincare. They also offer a "whole-plant extract" option, which includes other beneficial compounds from milk thistle (like fatty acids and vitamins) for brands marketing "full-spectrum" products. Mountain View Extracts is committed to small-batch production, ensuring each batch is carefully tested for potency and purity. While their prices are on the higher side, clients say the quality and sustainability focus are worth the investment.

Standout feature: A "farm tour" program, where clients can visit their partner milk thistle farms in the Alps to see the sourcing process firsthand.
