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

Established in 2005, Singapore Botanical Extracts Co. (SBEC) is a household name in the local botanical extract scene, and silymarin is their crown jewel. What sets them apart? Their vertically integrated model: they source milk thistle seeds directly from organic farms in Europe and Australia, process them in-house at their Singapore facility, and distribute globally. This control over the supply chain ensures consistency—something crucial for silymarin, where potency can vary based on seed quality and extraction methods. SBEC specializes in two main silymarin lines: pharmaceutical-grade (with silymarin purity up to 98%) and bulk cosmetic-grade (ideal for skincare formulations). They're one of the few suppliers in Singapore with Organic Certified botanical extracts, meeting both USDA and EU organic standards, which is a big plus for brands targeting eco-conscious consumers. Their GMP-certified facility adheres to strict hygiene protocols, and every batch undergoes HPLC testing to verify silymarin content, heavy metal levels, and microbial safety. Clients praise SBEC for their flexibility—they offer custom blends (e.g., silymarin combined with other liver-supporting herbs like artichoke extract) and small-batch production for startups, though their minimum order for bulk orders is 50kg. They also excel in fast turnaround times, with most local orders delivered within 3–5 business days and international shipments (to Malaysia, Indonesia, and beyond) within a week. If you're looking for a one-stop shop for high-quality, certified silymarin, SBEC is a solid bet.

For businesses that demand the highest purity silymarin, GreenHarvest Nutraceuticals is the go-to. Founded in 2010 by a team of pharmaceutical scientists, this supplier focuses exclusively on high-potency extracts, and their silymarin is no exception—they regularly hit 95%+ purity, making it a favorite for pharmaceutical formulations and clinical studies. What makes GreenHarvest stand out? Their rigorous testing process. Every batch is tested in-house using ultra-performance liquid chromatography (UPLC) for precision, and they also partner with third-party labs like SGS to validate results. This commitment to transparency has earned them FDA registration, a must for any supplier selling into the U.S. pharmaceutical market, as well as Halal and Kosher certifications, opening doors to Middle Eastern and Jewish markets. While their core focus is pharmaceutical-grade silymarin, they also cater to sports nutrition brands, offering micronized silymarin powder that dissolves easily in pre-workout drinks and protein shakes. Their minimum order is 25kg, which is lower than many pharma-focused suppliers, making them accessible to mid-sized brands. Clients note their responsive technical support team, which is always on hand to provide COAs (Certificates of Analysis) and help with formulation questions. If your priority is scientific accuracy and high purity, GreenHarvest won't disappoint.

When it comes to sheer volume, BulkExtracts Singapore is the heavyweight in the room. This wholesaler specializes in bulk silymarin, catering to large-scale manufacturers in food, beverage, and animal health industries. Whether you need 100kg or 10,000kg, they have the capacity to deliver—their warehouse in Jurong houses over 500 metric tons of botanical extracts at any given time, ensuring quick fulfillment even for massive orders. BulkExtracts focuses on affordability without skimping on quality. Their silymarin is sourced from trusted farms in India and China, and while they don't specialize in organic products, they do hold ISO 22000 (food safety) and GMP certifications, ensuring compliance with global food standards. Their most popular product is their standard silymarin powder (80% purity), which is used in everything from liver support gummies to functional energy drinks. What clients love most is their pricing model—bulk orders over 500kg come with significant discounts, and they offer flexible payment terms for repeat customers. They also provide private labeling services, making it easy for wholesalers to rebrand the product for their own clients. If you're a large manufacturer or wholesaler looking to stock up on silymarin at scale, BulkExtracts is the way to go.

For brands that prioritize organic and sustainable sourcing, OrganicMeds Asia is a standout. This supplier has built its reputation on organic certified silymarin, with every batch traceable back to family-owned farms in Germany and France that use regenerative farming practices. Their commitment to organic integrity has earned them USDA Organic and EU Organic certifications, as well as a spot on the Singapore Organic Association's list of trusted suppliers. OrganicMeds' silymarin is cold-extracted to preserve heat-sensitive compounds, resulting in a product with higher levels of silibinin (the most active component of silymarin) than many conventional extracts. This makes it a hit with natural supplement brands and skincare companies, where "clean" ingredients are a top selling point. Their product range includes organic silymarin powder, liquid extracts, and even encapsulated silymarin for ready-to-sell supplements. With a minimum order of just 10kg, they're accessible to small and medium-sized businesses, and they offer free samples so you can test the quality before committing. Clients rave about their storytelling support—they provide farm profiles and extraction process videos, which brands can use in marketing materials to highlight their organic credentials. If "organic" is non-negotiable for your brand, OrganicMeds Asia delivers.

PharmaGrade's silymarin is used in prescription liver medications and clinical trials, so consistency is non-negotiable.

They also offer custom particle sizes to meet specific dissolution requirements, working closely with clients' R&D teams to fine-tune products.

They also provide comprehensive documentation, including DMFs (Drug Master Files) for clients looking to register products with the FDA or EMA. For pharmaceutical manufacturers, PharmaGrade Solutions is a trusted partner.

Sustainability isn't just a buzzword for EcoBotanicals SG—it's their core mission. This supplier sources milk thistle from farms that use regenerative agriculture practices, such as crop rotation and natural pest control, and their extraction process uses 100% renewable energy, earning them carbon-neutral certification. They even offset any remaining emissions by investing in reforestation projects in Southeast Asia. Their silymarin is available in both organic and conventional options, but even their conventional extracts are free from synthetic solvents—they use ethanol derived from sugarcane, a more eco-friendly alternative to petroleum-based solvents. This commitment to green practices has made them a favorite among eco-conscious skincare brands, who use their silymarin in anti-aging serums (thanks to its ability to protect skin cells from environmental damage).
