Milk thistle extract, celebrated for its silymarin content and liver-supporting properties, has become a staple in health and wellness industries. But with so many options out there, how do you choose the right partner? We've rounded up the top 10 milk thistle extract suppliers, manufacturers, wholesalers, and traders across Australia to simplify your search. From family-run manufacturers to large-scale wholesalers, each entry on this list brings something unique to the table, whether it's organic certification, bulk pricing, or specialized formulations.
Why Milk Thistle Extract Matters
Before diving into the suppliers, let's quickly touch on why milk thistle extract is in such high demand. Derived from the seeds of the Silybum marianum plant, this extract is rich in silymarin, a flavonoid complex known for its antioxidant and anti-inflammatory effects. It's most famous for supporting liver health, but it's also used in supplements for detox, in skincare for its soothing properties, and even in pharmaceuticals for its potential therapeutic benefits. As consumers increasingly seek natural ingredients, the demand for high-quality, pure milk thistle extract has skyrocketed—and Australian suppliers are stepping up to meet that need.
Top 10 Milk Thistle Extract Suppliers in Australia
1. Aussie Herbal Extracts Pty Ltd (Manufacturer)
Aussie Herbal Extracts has been a cornerstone of Australia's botanical extract industry for over 20 years, and their milk thistle extract is a standout product. As a milk thistle extract manufacturer , they control the entire production process, from sourcing non-GMO milk thistle seeds (locally grown in Victoria and South Australia) to extracting and testing the final product. What sets them apart is their commitment to cold-press extraction, which preserves the maximum potency of silymarin—often hitting 80-85% purity, well above industry averages.
Their product line includes both powder and liquid extracts, making them versatile for different applications: powder for capsules and tablets, liquid for tinctures and skincare serums. They're also big on sustainability—their extraction process uses minimal water, and they partner with local farmers who follow regenerative agriculture practices. For bulk buyers, they offer bulk milk thistle extract in 25kg drums, with MOQs starting at 50kg for custom formulations. Certifications? They hold GMP, ISO 9001, and organic certification from the Australian Certified Organic (ACO) body, so you can trust the purity.
Industries they cater to: Dietary supplements, natural pharmaceuticals, and eco-friendly skincare brands. Customers rave about their consistent quality and responsive customer service—many note that their technical team is always on hand to help with formulation questions.
2. Green Valley Wholesale (Wholesaler)
If you're a small to medium-sized business looking for flexible ordering options, Green Valley Wholesale is worth a look. As a dedicated wholesaler, they specialize in connecting manufacturers with buyers, offering a wide range of botanical extracts—including milk thistle—at competitive prices. They source their milk thistle extract from trusted overseas manufacturers (primarily in Europe and the US) but subject every batch to third-party testing in Australian labs to ensure it meets local standards.
Their milk thistle extract comes in standard 80% silymarin powder, with options for organic or conventional sourcing. What's unique here is their low MOQ: you can order as little as 1kg, making them ideal for startups or businesses testing new products. They also offer fast turnaround—most orders ship within 2-3 business days across Australia, and they even provide same-day delivery in major cities like Sydney and Melbourne. While they don't manufacture in-house, their strict quality control process (including COA and MSDS for every batch) ensures you're getting a reliable product.
Target industries: Small supplement brands, herbalists, and natural skincare startups. One customer review summed it up: "As a new brand, we couldn't commit to large bulk orders. Green Valley's low MOQ and quick shipping let us launch our milk thistle capsules without breaking the bank."
3. Pure Botanicals Australia (Manufacturer & Trader)
Pure Botanicals Australia wears two hats: they're both a manufacturer and a trader, giving them the flexibility to cater to diverse needs. As a manufacturer, they produce their own line of high-purity milk thistle extract using a proprietary supercritical CO2 extraction method, which results in a solvent-free product with silymarin levels up to 90%. This makes their extract popular with pharmaceutical companies and high-end supplement brands that prioritize purity.
As a trader, they also import specialty milk thistle extracts from global partners, including organic and standardized varieties (like 70% silymarin for more cost-effective options). Their standout offering is their "Custom Blend" service—if you need a specific silymarin concentration or a blend with other extracts (like dandelion or artichoke for liver support formulas), they'll create it for you. They're certified by the Therapeutic Goods Administration (TGA), which is a big plus for businesses in the pharmaceutical sector.
Bulk options are available in 50kg and 100kg bags, and they offer free samples so you can test before committing. Their customer base includes some of Australia's biggest supplement brands, and they pride themselves on transparency—you can request a full traceability report for any batch, from seed origin to extraction date.
4. Bulk Botanicals Co. (Wholesaler)
Bulk Botanicals Co. lives up to its name, focusing solely on bulk milk thistle extract and other botanical powders for large-scale buyers. They're a go-to for businesses that need consistent, high-volume supplies—think contract manufacturers producing thousands of supplement bottles monthly. Their milk thistle extract is sourced from verified suppliers in Germany and Poland (known for their strict agricultural standards) and is available in both conventional and organic (EU-certified) options, with silymarin purity ranging from 60% to 85%.
What makes them a top choice? Their pricing. By buying in massive quantities and passing savings on to customers, they offer some of the lowest per-kilogram rates in Australia. They also have a dedicated logistics team that ensures on-time delivery, even for last-minute orders. MOQs start at 100kg, but they're willing to negotiate for long-term contracts. They don't offer custom formulations, but their standard product is highly consistent—many customers note that batch-to-batch variation is minimal, which is crucial for maintaining product quality.
Industries served: Large supplement manufacturers, food and beverage companies (for functional drinks), and export businesses shipping to New Zealand and Southeast Asia. They're also TGA-registered, so their extract meets the strict standards required for therapeutic products.
5. EcoExtracts Australia (Manufacturer & Wholesaler)
EcoExtracts Australia is all about sustainability—and their milk thistle extract reflects that mission. As both a manufacturer and wholesaler, they produce their own extract using 100% organic milk thistle seeds sourced from certified organic farms in Tasmania (where the cool climate and rich soil result in high-silymarin seeds). Their extraction process uses 100% renewable energy, and they even recycle the leftover seed meal as animal feed, leaving zero waste.
Their organic milk thistle extract is certified by ACO and the EU Organic label, making it ideal for brands marketing to eco-conscious consumers. The extract is available in powder form (80% silymarin) and as a concentrated liquid (for skincare and tinctures). They also offer a "Raw Extract" option, which is minimally processed and retains more of the plant's natural oils—popular with herbalists and natural skincare formulators.
For wholesalers, they have flexible MOQs: 5kg for small businesses, 50kg for bulk orders. They also provide private labeling services, so you can slap your brand on their extract without investing in manufacturing. Their customer service team is known for being incredibly helpful—one startup founder shared, "They walked us through the entire process, from choosing the right extract to designing our labels. We couldn't have launched without them."
6. Southern Cross Botanicals (Trader)
Southern Cross Botanicals is a trader with a global network, specializing in hard-to-find botanical extracts—and their milk thistle extract is a prime example. They partner with milk thistle extract supplier s in Italy, Hungary, and China, curating a selection of extracts to suit different budgets and needs. Whether you need a budget-friendly conventional extract (60% silymarin) for basic supplements or a premium organic extract (85% silymarin) for high-end products, they've got you covered.
What sets them apart is their focus on niche markets. For example, they offer a "Cold-Pressed Liposomal" milk thistle extract, which is encapsulated in liposomes for better absorption—perfect for supplements targeting maximum bioavailability. They also stock liquid extracts with added vitamin E for skincare, which enhances the extract's antioxidant properties. Their MOQs are low (starting at 1kg), and they offer fast shipping from their warehouse in Brisbane, with most orders arriving within 3-5 business days.
They're not a manufacturer, so they don't control the extraction process, but they make up for it with rigorous testing. Every batch is third-party tested for heavy metals, pesticides, and silymarin content, and they provide a detailed COA with every order. Their customer base includes small herbal shops, online supplement brands, and even naturopaths who recommend their extracts to patients.
7. Natural Extracts Victoria (Manufacturer)
Natural Extracts Victoria is a family-owned manufacturer based in Ballarat, Victoria, with a focus on traditional extraction methods. Their milk thistle extract is made using a water-based maceration process, which is gentler than chemical extraction and results in a more "whole plant" extract—retaining not just silymarin, but also other beneficial compounds like flavonoids and fatty acids. This makes their extract popular with brands marketing "full-spectrum" products.
Their silymarin purity is around 70%, which is slightly lower than some competitors, but many customers prefer this because it includes the plant's natural synergistic compounds. They source their milk thistle seeds from local Victorian farmers, supporting the regional economy, and their small-batch production ensures attention to detail. Products are available in powder (25kg drums) and liquid (5L bottles), with MOQs of 5kg for powder and 1L for liquid.
They're certified organic by ACO and have a GMP-compliant facility. What customers love most is their personalized service—since they're a small team, you'll work directly with the owners, who are happy to adjust extraction parameters (like concentration or particle size) to meet your needs. They're a great choice for brands that value craftsmanship and local sourcing.
8. Global Botanicals Australia (Trader & Exporter)
Global Botanicals Australia is a trader with a global reach, exporting Australian-made and imported botanical extracts to over 20 countries—but they also serve the domestic market with top-notch milk thistle extract. They source their primary milk thistle extract from a milk thistle extract manufacturer in Austria (known for its strict organic standards) and also offer an Australian-made option from their partner facility in New South Wales. This dual sourcing gives customers flexibility: the Austrian extract is organic and high-purity (85% silymarin), while the Australian extract is more cost-effective (70% silymarin, conventional).
Their claim to fame is their "Rapid Test" service—if you're unsure about a batch, they'll run a quick silymarin assay in their in-house lab and provide results within 24 hours. This is a lifesaver for businesses with tight production deadlines. They also offer a range of packaging options, from small 1kg foil bags for startups to 1-tonne bulk bags for large manufacturers. MOQs start at 5kg, and they offer discounts for repeat orders.
They're particularly popular with export-focused businesses, as they handle all the paperwork (like export certifications and customs declarations) to make international shipping seamless. Their customer service team is multilingual, speaking English, Mandarin, and Spanish, which helps with global clients.
9. Wellness Extracts Wholesale (Wholesaler)
Wellness Extracts Wholesale is a niche wholesaler focusing on natural and organic botanical extracts, and their milk thistle extract is a customer favorite. They source exclusively from organic-certified suppliers, with their milk thistle extract coming from a family-run farm in France that has been growing milk thistle for generations. The extract is standardized to 80% silymarin and is available in both powder and liquid forms, with the liquid option being alcohol-free—perfect for brands targeting alcohol-sensitive consumers (like children's supplements or wellness tinctures).
What makes them stand out is their focus on education. They provide free resources to their customers, including formulation guides (e.g., "How to Blend Milk Thistle with Turmeric for Liver Support") and market trend reports (e.g., "The Rise of Milk Thistle in Skincare"). This added value helps their clients create better products and stay ahead of industry trends. MOQs are low (1kg for powder, 500ml for liquid), and they offer free shipping on orders over $500.
Their customer base is primarily small to medium-sized supplement brands, natural skincare companies, and health food stores. They're also certified by the Organic Food Chain (OFC), so you can trust that their organic claims are legitimate.
10. Outback Botanicals (Manufacturer)
Rounding out our list is Outback Botanicals, a newer player in the industry but already making waves with their innovative milk thistle extract. As a manufacturer, they've invested in state-of-the-art ultrasonic extraction technology, which uses sound waves to break down plant cell walls, resulting in a higher yield and more concentrated extract. Their silymarin purity consistently hits 85-90%, making it one of the most potent on the market.
They specialize in microencapsulated milk thistle extract, which is coated in a plant-based shell to protect the silymarin from stomach acid, ensuring it's absorbed in the intestines where it's most effective. This makes their extract ideal for supplements targeting maximum bioavailability. They also offer a "Water-Soluble" version, which dissolves easily in liquids—great for functional drinks, smoothies, and liquid supplements.
While they're a smaller manufacturer, they're growing quickly, thanks to their focus on innovation. MOQs start at 25kg, but they offer reduced rates for pre-orders. They're also committed to transparency—their website features a live "Batch Tracker" where you can enter a lot number and see the full testing results, from silymarin content to heavy metal levels. If you're looking for cutting-edge milk thistle extract, Outback Botanicals is worth keeping an eye on.

Frequently Asked Questions
Q: What's the typical silymarin purity for milk thistle extract?
A: Most suppliers offer silymarin purity between 60% and 90%. For supplements, 70-85% is standard, while pharmaceutical applications may require 85% or higher. Always check the COA for exact numbers.
Q: Is organic milk thistle extract worth the extra cost?
A: It depends on your target market. If you're selling to health-conscious consumers or in the natural skincare space, organic certification can justify a higher price point. If cost is a priority and your customers don't prioritize organic, conventional extract is a solid option.

Q: Can I get a custom formulation (e.g., milk thistle + other extracts)?
A: Yes! Manufacturers like Pure Botanicals Australia and Aussie Herbal Extracts offer custom blending services. Wholesalers may not, but some traders (like Southern Cross Botanicals) can source pre-blended extracts from their partners.
