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

Founded in 2005, Indonesia Botanical Extracts Co. (IBEC) has grown to become one of the country's leading manufacturers of silymarin and milk thistle extract. With a state-of-the-art production facility in West Java, IBEC specializes in large-scale extraction, capable of processing over 500 tons of milk thistle seeds annually. This capacity makes them a top choice for businesses needing consistent bulk supplies.

IBEC's product line includes silymarin with purity levels ranging from 80% to 95%, as well as crude milk thistle extract for less demanding applications. What sets them apart is their rigorous quality control process: every batch undergoes HPLC testing to ensure silymarin content, along with checks for heavy metals, pesticides, and microbial contaminants. Their commitment to consistency has earned them long-term partnerships with pharmaceutical companies across Southeast Asia and Europe.

Certified by ISO 9001 and GMP, IBEC also caters to markets requiring Halal certification, making their products accessible to a broad range of customers. For businesses prioritizing reliability and scale, IBEC's minimum order of 50kg (with discounts for bulk orders over 500kg) positions them as a workhorse in the Indonesian silymarin industry.

Java Silymarin Manufacturers (JSM) is a name synonymous with pharmaceutical-grade quality. Based in Semarang, Central Java, JSM focuses exclusively on producing silymarin that meets the strict standards of the pharmaceutical and nutraceutical industries. Their claim to fame? A proprietary extraction method that preserves silymarin's bioactivity while achieving purity levels of up to 95%—a benchmark that few suppliers in Indonesia can match.

JSM's facility is certified under ISO 22000 and GMP, and their products comply with USP (United States Pharmacopeia) standards, ensuring they meet the requirements of regulatory bodies like the FDA. This attention to detail makes them a preferred supplier for companies developing liver support medications, prescription supplements, and clinical nutrition products.

Beyond standard silymarin powder, JSM offers custom formulations, including microencapsulated silymarin for improved bioavailability and liquid extracts for use in syrups and suspensions. While their minimum order of 100kg may be steep for small businesses, their technical support team—available to assist with formulation and regulatory compliance—adds significant value for clients in highly regulated sectors.

For businesses prioritizing organic and sustainable ingredients, Bali Organic Extracts (BOE) is a standout choice. Located in Ubud, Bali, BOE partners with small-scale farmers in East Java to grow organic milk thistle, ensuring every step of the supply chain adheres to organic principles—from seed selection to extraction.

BOE's organic silymarin (certified by USDA Organic and EU Organic) is a hit among natural supplement brands and eco-conscious cosmetic companies. Their product range includes silymarin powder (80-90% purity) and cold-pressed milk thistle extract oil, which is gaining popularity in skincare for its antioxidant and anti-inflammatory properties. Unlike many suppliers, BOE is transparent about their sourcing: they publish annual sustainability reports and even offer farm tours for clients wanting to verify their practices.

With a minimum order of 25kg, BOE is accessible to small and medium-sized businesses, and their wholesale pricing (starting at $45/kg for 100kg orders) makes organic silymarin more affordable than imported alternatives. For brands building a story around sustainability, BOE's commitment to fair trade and eco-friendly extraction (they use 30% less water than conventional methods) is a powerful marketing asset.

Sumatra Pharma Ingredients (SPI) isn't just a supplier—they're a research partner for companies pushing the boundaries of silymarin applications. Headquartered in Medan, SPI operates a dedicated R&D lab alongside their production facility, where a team of biochemists works on optimizing extraction techniques and developing novel silymarin-based ingredients.

Their flagship product is high-purity silymarin (95%+), which is used in clinical trials and specialized pharmaceutical formulations. SPI also offers silymarin conjugates, such as silymarin-phosphatidylcholine complexes, designed to enhance absorption in the body. For clients with unique needs, SPI provides custom extraction services, including modifying particle size for better dissolution or creating water-soluble silymarin for beverage applications.

Certified under ISO 13485 (a standard for medical devices) and compliant with EP (European Pharmacopoeia) standards, SPI caters to the most demanding markets, including Europe and North America. Their minimum order of 200kg reflects their focus on large-scale pharmaceutical clients, but they occasionally partner with startups on pilot projects—making them a great fit for innovative brands with long-term growth plans.

Not all businesses need to work directly with manufacturers, and Jakarta Bulk Traders (JBT) fills that gap by acting as a bridge between Indonesian producers and global buyers. Established in 2010, JBT sources silymarin from a network of vetted manufacturers across Indonesia, offering clients a one-stop shop for various purity levels, forms, and certifications.

JBT's strength lies in flexibility. They cater to both small businesses (with retail orders as low as 10kg) and large wholesalers (minimum 500kg for wholesale pricing), and their product range includes everything from crude milk thistle extract to ultra-pure silymarin. For international buyers, JBT handles logistics, including customs clearance, documentation, and shipping—eliminating the hassle of navigating Indonesian export regulations.

Certified by ISO 9001, JBT also ensures quality by conducting third-party testing on every batch they source. They're particularly popular among buyers in the Middle East and Africa, where their Halal and Kosher certifications are in high demand. If you're new to sourcing silymarin from Indonesia, JBT's team of multilingual account managers can guide you through the process, from selecting the right product to negotiating payment terms.

Riau Natural Extracts (RNE) takes control of the entire supply chain by owning and operating its own milk thistle farms in Riau province. This vertical integration—from cultivating seeds to extracting silymarin—allows RNE to monitor quality at every stage, resulting in a more consistent product and lower costs.

RNE's farms use sustainable agricultural practices, including crop rotation and natural pest control, reducing reliance on chemicals. The seeds are harvested by hand to ensure ripeness, then transported to their on-site extraction facility, where they're processed within 24 hours to preserve freshness. The result is milk thistle extract with high silymarin yields (typically 18-20% from seeds, compared to the industry average of 15-17%).

While RNE offers organic-certified silymarin for ｓｅｌｅｃｔ batches, their primary focus is on affordable, high-quality extracts for the supplement market. Their standard silymarin powder (80% purity) is priced competitively at $38/kg for orders over 100kg, making them a favorite among budget-conscious supplement brands. Certified by GMP and ISO 22000, RNE's minimum order of 30kg strikes a balance between accessibility and scale, appealing to mid-sized businesses looking to cut costs without compromising on quality.

While many silymarin suppliers focus on pharmaceuticals and supplements, Surabaya Health Ingredients (SHI) has carved a niche in the cosmetics industry. Based in Surabaya, East Java, SHI specializes in formulating silymarin extracts tailored for skincare, haircare, and personal care products.

SHI's product line includes silymarin oil (for serums and moisturizers), water-soluble silymarin (for toners and masks), and encapsulated silymarin (for controlled-release in anti-aging products). Their extracts are prized for their ability to soothe irritated skin, protect against environmental damage, and support collagen production—benefits backed by in-house clinical trials. SHI also offers custom blending, allowing cosmetic brands to combine silymarin with other botanical extracts like green tea or aloe vera.

Certified by Ecocert and GMP, SHI adheres to the strict ingredient standards of the cosmetics industry, including EU regulations on preservatives and allergens. Their minimum order of 15kg is lower than many manufacturers, making them accessible to indie beauty brands. For businesses launching natural skincare lines, SHI's technical team provides formulation support, helping clients integrate silymarin effectively into their products.

For businesses needing silymarin in truly massive quantities, Lombok Extracts Wholesale (LEW) is the go-to supplier. Located in Mataram, Lombok, LEW operates one of the largest extraction facilities in Indonesia, with a annual capacity of over 1,000 tons of milk thistle extract. This scale allows them to offer some of the lowest prices in the market—starting at $32/kg for orders over 1,000kg.

LEW's product range is straightforward: crude milk thistle extract (for industrial applications), standard silymarin powder (80-85% purity), and bulk silymarin for reprocessing. They focus on efficiency, using solvent-free extraction methods to reduce costs and environmental impact. While they don't offer the same level of customization as specialized manufacturers, their reliability and low pricing make them a favorite among large-scale supplement producers and animal feed companies (silymarin is increasingly used in livestock supplements to support liver health).

Certified by ISO 9001 and GMP, LEW prioritizes consistency and on-time delivery, with a track record of fulfilling orders within 7-10 business days for in-stock products. Their minimum order of 1,000kg is a barrier for small businesses, but for industrial buyers, LEW's combination of price and scale is hard to beat.

Many businesses don't just need silymarin—they need finished products, and Kalimantan Botanical Solutions (KBS) specializes in turning raw extracts into market-ready supplements. Based in Balikpapan, KBS offers comprehensive OEM and private label services, including capsule filling, tablet pressing, and packaging design.

KBS sources high-quality silymarin from partner manufacturers (including some on this list) and transforms it into liver support capsules, silymarin softgels, and powdered drink mixes. Their facility is equipped with automated production lines, capable of producing up to 500,000 capsules per day, and they offer a range of packaging options, from bulk bottles to single-serve sachets. For brands without in-house R&D, KBS provides formulation support, helping clients develop unique products (e.g., silymarin combined with turmeric or vitamin E).

Certified by GMP and Halal, KBS caters to both local Indonesian brands and international clients looking to white-label supplements. Their minimum order varies by product (e.g., 10,000 capsules for private label), and they offer low MOQs for new brands testing the market. For businesses wanting to launch a silymarin supplement without investing in manufacturing infrastructure, KBS is a turnkey solution.

Not every buyer needs pharmaceutical-grade silymarin, and Yogyakarta Natural Remedies (YNR) caters to the budget end of the market. Founded in 2015, YNR focuses on producing low-purity silymarin (40-60%) and crude milk thistle extract, ideal for traditional medicine, animal supplements, and low-cost herbal products.

YNR's production process is simpler than that of larger manufacturers, using ethanol extraction and basic filtration, which keeps costs down. Their products are sold at wholesale prices starting at $25/kg, making them accessible to small-scale herbalists, local pharmacies, and startups with limited budgets. While YNR doesn't offer the same certifications as premium suppliers, they do conduct basic quality tests for silymarin content and microbial safety.

With a minimum order of just 5kg, YNR is a lifeline for small businesses and traditional medicine practitioners in Indonesia and neighboring countries. Their focus on affordability and accessibility ensures that even smaller players can incorporate silymarin into their offerings, supporting the growth of the natural health market at the grassroots level.
