Why Silymarin Matters: A Quick Refresher
Before we dive into the top importing countries, let's ground ourselves in why silymarin is in such high demand. Silymarin is the active ingredient in milk thistle extract, and its benefits read like a wellness wishlist: it supports liver function by protecting cells from damage, aids in detoxification, and may even have anti-aging properties for the skin. With rising rates of non-alcoholic fatty liver disease (NAFLD) and a global shift toward "clean" supplements, it's no wonder the market for silymarin is booming. In 2024, the global silymarin market was valued at over $600 million, and projections suggest it will grow by 7.2% annually through 2025—meaning importing countries are gearing up for even more shipments.

1. United States: The Heavyweight of Silymarin Imports
When it comes to silymarin, the U.S. isn't just a player—it's the MVP. With an estimated 1,250 tons of imports in 2025, the country leads the pack, driven by a perfect storm of factors: an aging population, skyrocketing interest in liver health, and a $50-billion dietary supplement industry that can't get enough of natural ingredients.
Here's why the U.S. can't get enough: First, liver health is a national concern. NAFLD affects over 80 million Americans, and silymarin is often the go-to supplement for those looking to support their liver without prescription drugs. Second, the supplement boom shows no signs of slowing down. Brands like Nature's Bounty and NOW Foods have made milk thistle extract a staple on pharmacy shelves, and consumers are increasingly seeking out "clean label" products—meaning demand for high-purity silymarin (often imported from Europe or China) is rising.
But it's not just supplements. The pharmaceutical sector in the U.S. is also a major importer, using silymarin in liver support medications and even topical creams for skin conditions (thanks to its anti-inflammatory properties). The FDA's recent green light for certain silymarin-based clinical trials has only boosted confidence in its efficacy, making pharmaceutical-grade imports a priority.
Of course, it's not all smooth sailing. U.S. importers face hurdles like strict FDA regulations (which require rigorous testing for purity and contaminants) and supply chain delays, especially when sourcing from distant regions. But with a projected 7.5% growth rate through 2030, the U.S. shows no signs of stepping down from its top spot.
2. Germany: Quality-Driven Demand in the Heart of Europe
Germany is a close second, importing around 820 tons of silymarin in 2025. What sets Germany apart? A long-standing love for herbal medicine and a pharmaceutical industry that prioritizes quality above all else. In Germany, herbal remedies aren't just "alternatives"—they're integrated into mainstream healthcare, with silymarin holding a special place in treatments for liver disorders.
German consumers and regulators alike demand excellence, which is why most imported silymarin here is pharmaceutical grade. Suppliers from Eastern Europe (like Hungary and Poland) and organic-certified producers in France are top sources, as they meet Germany's strict standards for purity and sustainability. The country's pharmaceutical giants, such as Bayer and Merck, rely on consistent imports to meet demand for liver medications and herbal supplements.
Another trend? Cosmetics. While not as large as the pharmaceutical sector, German beauty brands are starting to incorporate silymarin into anti-aging serums and creams, thanks to its ability to soothe inflamed skin and protect against environmental damage. This emerging market is expected to push import volumes even higher in the next five years.
Challenges? Germany's focus on quality comes with a price tag. Sourcing organic or sustainably harvested silymarin often costs more, and recent energy price hikes in Europe have added to transportation costs. Still, with a 6.8% growth rate, Germany's commitment to herbal health ensures it will remain a key player.
3. Japan: Blending Tradition and Innovation
Japan may be third on the list, but it's growing faster than most—projected to see an 8.2% increase in silymarin imports by 2030. What's driving this? A society that values natural remedies, an aging population (over 28% of Japanese are 65 or older), and a booming nutraceutical industry that blends traditional medicine with modern science.
In Japan, silymarin is often marketed as part of "kampo" (traditional herbal medicine) blends, appealing to consumers who trust time-tested ingredients. It's also a star in functional foods—think liver-supporting teas, energy bars, and even soft drinks. Japanese importers primarily source from China and South Korea, drawn by lower costs and proximity, though there's a growing preference for organic-certified silymarin from Europe.
The country's regulatory body, the Ministry of Health, Labour and Welfare (MHLW), has approved silymarin for use in certain health claims, which has further boosted its popularity. For example, products can now advertise "supports liver function" if they meet specific silymarin content criteria—a game-changer for brands looking to stand out on store shelves.
One challenge for Japan? Limited domestic production of milk thistle, which means it relies almost entirely on imports. But with consumers willing to pay a premium for effective, natural products, the country's import volumes are set to climb.
4. Australia: A Small Market with Big Growth
Australia might import "only" 480 tons in 2025, but don't sleep on this market—it's growing at a whopping 9.1% rate, the fastest on our list. Why? Australians are obsessed with wellness, and liver health has become a hot topic, thanks to high rates of alcohol consumption and fatty liver disease. Add in a thriving natural health product industry, and you've got the perfect recipe for silymarin demand.
Most silymarin in Australia ends up in dietary supplements, with brands like Swisse and Blackmores leading the charge. But there's also a niche market in veterinary health—Australian farmers are increasingly using silymarin to support liver function in livestock, especially sheep and cattle. Imports come primarily from China (due to cost) and Germany (for high-end pharmaceutical-grade products).
Regulations here are strict but transparent, overseen by the Therapeutic Goods Administration (TGA). This gives consumers confidence, which in turn drives demand. And with a growing interest in plant-based and organic products, importers are starting to seek out certified organic silymarin, even if it costs more.
The main challenge? Distance. Sourcing from Europe or the U.S. means longer shipping times and higher costs, but Australian importers are getting creative—partnering with local distributors in Asia to streamline supply chains. With such a high growth rate, Australia is one to watch.
5. Canada: North America's Steady Contender
Rounding out the top five is Canada, importing around 390 tons of silymarin in 2025. Like its southern neighbor, Canada's demand is fueled by an aging population and a love for natural supplements. But there's a twist: Canada has a strong focus on integrative medicine, where silymarin is often recommended by naturopaths and medical doctors alike for liver support.
The country's supplement market is thriving, with brands like Jamieson and Natural Factors offering milk thistle extract products in everything from capsules to liquid tinctures. Pharmaceutical use is also on the rise, particularly in treatments for liver cirrhosis and hepatitis. Most imports come from the U.S. (for convenience) and China (for cost-effectiveness), though there's a growing trend toward sourcing from sustainable European suppliers.
Canada's regulatory body, Health Canada, has approved silymarin for use in natural health products, setting clear standards for dosage and purity. This has helped build trust among consumers, who are increasingly cautious about supplement quality.
Challenges include seasonal supply fluctuations (milk thistle harvests are weather-dependent) and competition from other liver-support ingredients. But with a 7% growth rate, Canada remains a steady and reliable importer.
Looking Ahead: The Future of Silymarin Imports
As we've seen, the key importing countries for silymarin in 2025 are united by a few common threads: aging populations, a focus on natural health, and robust industries (pharmaceuticals, supplements, functional foods) that rely on this versatile ingredient. But each country has its own unique drivers—whether it's Germany's love for herbal medicine, Japan's blend of tradition and innovation, or Australia's fast-growing wellness scene.
Looking forward, two trends will shape import patterns: sustainability and innovation. Consumers are increasingly asking where their silymarin comes from, pushing importers to source from organic, responsibly harvested farms. And as research uncovers new uses for silymarin (like in skincare or animal health), demand will only grow.
So, whether you're a supplier looking to expand or a consumer curious about the journey of your liver supplement, one thing is clear: silymarin is more than just an ingredient—it's a global phenomenon, and these key importing countries are leading the way.
