Who supplies wholesale milk thistle in the EU?

Milk thistle (Silybum marianum) seed is field-grown across Eastern Europe — Romania, Hungary, the Balkans — and the Mediterranean, while most silymarin extract volume comes from China. It is traded as cleaned seed, seed powder, cold-pressed seed oil and standardised extract (for example 80% silymarin by HPLC). TANDOR is an introducer based in Romania: you send the product, form, quantity and delivery country, we ask EU producers for written offers and introduce you directly — the producer sells and invoices you. Organic status is the producer's own certificate, which you check in EU TRACES. Prices are quoted on request, based on a current offer from the supplier.

Romania / Eastern Europe — EU-Organic field crop

Silybum marianum is field-cultivated across Eastern Europe (Romania, Hungary, the Balkans) and the Mediterranean; the EU-Organic seed and silymarin-extract supply chain is well-established. EU-origin seed gives the standardised-extract buyer a shorter, traceable chain versus the dominant volume origin.

China — global extract-volume origin

China is the dominant volume origin for silymarin extract; many EU buyers blend EU-origin seed traceability with the standardised assay. Seed silymarin content is variety- and season-dependent, so the extract buyer's anchor is the finished standardised silymarin %, not the raw-seed origin alone.

Quality controls & specifications

Milk thistle is bought two very different ways — raw seed (and seed powder or tea) on cleanliness and seed integrity, or standardised extract on the silymarin assay. Silymarin is a flavonolignan complex (silybin/silibinin A+B, silychristin, silydianin), so for extract the standardisation figure and the assay method are the contractual anchors, not the seed origin.

  • Standardised extract is sold to a silymarin %: 80% is the common nutraceutical grade — but the assay method matters, since UV spectrophotometry typically reads higher than HPLC on the same material
  • Silymarin is a complex (silybin A+B / silibinin, isosilybin, silychristin, silydianin) — the HPLC profile, not just total %, is the defensible extract spec
  • Raw seed is graded on purity (foreign matter, stones, other seeds), moisture and seed integrity; specify cleaning level and sieve
  • Seed silymarin content is variety- and season-dependent — for extract, contract on the finished standardised % rather than the raw seed
  • Cold-pressed seed oil is linoleic-acid-dominant with tocopherols; specify peroxide value and cool, dark, inert-headspace storage
  • Pesticide-residue + heavy-metal panel per EU Reg. 2023/915; EU-Organic operator/control-body ID on the COA
  • Microbiological panel per EU Reg. 2073/2005; powdered and tea grades may be steam-treated — confirm the method

Sample request: 100–500 g per format, dispatched by the producer after confirmation, against a signed non-disclosure note. Larger evaluation lots available against partial freight cost recovery during the pre-launch phase.

Frequently asked questions

Where can I source organic milk thistle seed and extract in the EU?+

TANDOR is a Romania-based introducer that puts EU buyers in touch with producers of Silybum marianum — cleaned seed, seed powder, herb cut, cold-pressed seed oil, and silymarin-standardised extract — from Romania, Hungary, Bulgaria and other EU origins; organic where the supplier holds the certificate, with the supplier's Certificate of Analysis per batch.

What does '80% silymarin' actually mean — and is it reliable?+

It's the standardised silymarin content of the extract. The catch is the assay method: UV spectrophotometry typically reads higher than HPLC on the same material, so two '80%' extracts can genuinely differ. Specify the method (HPLC preferred) and ask for the silybin A+B share, not just the total — that is the defensible spec.

Should I buy seed or extract?+

Buy seed (or seed powder) if you formulate whole-herb capsules, teas, or press your own oil — there the grade is cleanliness and integrity. Buy standardised extract if your label makes a silymarin claim — there you contract on the assayed % and HPLC profile, not the raw-seed origin.

Why does EU origin matter when China supplies most extract?+

China is the dominant volume origin for silymarin extract; EU-origin (Eastern-European / Mediterranean) seed and extract give shorter, traceable supply chains and EU-Organic certification, which matters for clean-label and EU-residue compliance. Many buyers pair EU-origin seed traceability with the standardised assay.

What about milk-thistle seed oil?+

Cold-pressed Silybum seed oil is linoleic-acid-dominant with tocopherols, used in cosmetics and nutrition. Specify peroxide value, extraction method (cold-pressed vs refined), and inert/dark storage — like other high-linoleic oils, it oxidises and needs protective packaging.
