Product Overview
Silymarin 80% Milk Thistle Extract is a standardized botanical extract powder commonly used in dietary supplements, capsules, tablets, and powder blends. It is typically produced from Silybum marianum seed extract and supplied according to an agreed silymarin specification.
For commercial sourcing, buyers should confirm the assay basis and analytical method together with the stated silymarin percentage. UV-based and HPLC-based results may represent different analytical approaches, so the specification should be reviewed before comparing materials from different suppliers.
For replacement or formulation projects, existing COA or specification data can be used as a reference for material matching, document review, and sample evaluation.

Applications
Dietary Supplements
Suitable for capsules, tablets, and other dietary supplement formulations requiring a standardized milk thistle extract with a defined silymarin specification.
Botanical Formulations
Can be used in botanical blends and multi-ingredient supplement formulas where milk thistle extract is included as a standardized botanical component.
Powder Blends / Sachets
Suitable for dry powder systems, premixes, and sachet formulations where good blending compatibility and powder handling are required. Flowability, particle size, and formulation compatibility should be evaluated during product development.
Customized Silymarin Formulations
Different silymarin specifications, including HPLC 50%, 55%, 60%, and 80%, can be reviewed according to formulation and sourcing requirements. For projects requiring improved water compatibility or a different active profile, alternative milk thistle extract grades may be considered.
How to Choose the Right Grade / Form
Choose by assay basis
Silymarin extract can be supplied according to different analytical and concentration requirements. In addition to standard commercial specifications, HPLC-based silymarin levels such as 50%, 55%, 60%, and 80% can be reviewed according to project requirements. Buyers should confirm the target assay method, required silymarin level, and chromatographic requirements before comparing materials from different suppliers.
Choose by application and formulation
For capsules, tablets, powder blends, and other dry supplement formulations, conventional standardized silymarin extract may be suitable. If the formulation requires improved dispersibility, water compatibility, or a different active profile, another milk thistle extract route may need to be evaluated.
Choose by existing specification or destination market
For replacement projects, providing the current COA or specification is usually the most reliable way to evaluate technical comparability. Buyers should also confirm document requirements, quality limits, residual solvent controls, and destination-market requirements before finalizing the commercial specification.
Technical & Formulation Notes
Technical Notes
Silymarin 80% is generally supplied as a standardized milk thistle extract rather than as a purified single-active ingredient. For sourcing and formulation review, buyers should confirm the assay basis, analytical method, and target specification together with the intended application.
Assay Basis and Specification Comparison
When sourcing Silymarin 80%, the stated percentage should be reviewed together with the analytical method. UV-based total silymarin results and HPLC-based flavonolignan results are not necessarily directly interchangeable, so materials described as “Silymarin 80%” may differ in analytical basis and commercial specification.
For supplier comparison, buyers should confirm the assay method, target specification, and chromatographic requirements rather than comparing the percentage or price alone. For replacement projects, providing the current COA or specification is usually the most reliable way to evaluate whether an alternative material is technically comparable.
Manufacturing & Process
Silymarin 80% Milk Thistle Extract is typically produced from Silybum marianum seeds through extraction, concentration, purification, drying, and standardization processes. The final material is supplied as a standardized botanical extract powder according to the agreed silymarin specification.
Extraction solvent, purification approach, assay basis, and drying conditions may influence the final composition and specification profile. For commercial projects, these process-related parameters should be reviewed together with the target assay method, residual solvent requirements, and destination-market documentation.
Compatibility / Formulation Notes
For capsules and tablets
Silymarin 80% is commonly used in solid dosage formulations such as capsules and tablets. Buyers should review particle size, bulk density, flowability, compression or encapsulation behavior, and compatibility with excipients during formulation development.
For powder blends / sachets
For dry blends and sachet formulations, blending uniformity, particle size distribution, bulk density, flowability, and compatibility with other powdered ingredients should be evaluated. Pilot testing is recommended when the formulation contains multiple botanical extracts or ingredients with different physical properties.
For beverages / water-based systems
Conventional Silymarin 80% has limited water solubility and is generally not the preferred option for clear beverages or formulations where water compatibility is a primary requirement. For these applications, a water-soluble or specially formulated milk thistle extract should be evaluated.
For multi-ingredient botanical formulas
In multi-ingredient formulations, buyers should consider color, odor, particle characteristics, blending behavior, and possible interactions with other botanical extracts, vitamins, minerals, or excipients. Final compatibility should be confirmed through formulation testing.
Storage / handling notes
Protect the material from heat, moisture, and direct light. Keep the package tightly closed during storage and handling, and avoid prolonged exposure to humid conditions after opening.
Extended QC & Test Items
Quality evaluation for Silymarin 80% commonly includes appearance, identification, silymarin assay, loss on drying, ash, particle size, heavy metals, residual solvents, and microbiological limits.
Depending on the specification and destination market, additional review may include lead, arsenic, cadmium, mercury, pesticide residues, aflatoxins, and specific solvent controls. Final testing requirements should follow the agreed product specification and applicable market requirements.

FAQ
Is Silymarin 80% the same as silybin or silibinin?
No. Silymarin 80% is generally supplied as a standardized milk thistle extract containing a mixture of flavonolignans, while silybin or silibinin refers to a more specific active component or higher-purity ingredient route.
Is Silymarin 80% suitable for capsules and tablets?
Yes. It is commonly used in capsules, tablets, powder blends, and other dry dietary supplement formulations.
Is conventional Silymarin 80% suitable for water-based formulations?
Conventional Silymarin 80% has limited water solubility and is generally not the preferred option for clear beverages or formulations requiring strong water compatibility. A water-soluble milk thistle extract should be evaluated for these applications.
What documents can you provide for Silymarin 80%?
COA, SDS, and TDS can be provided for specification review, technical evaluation, and purchasing approval. Additional documents can be discussed according to destination-market requirements.
What Silymarin HPLC specifications are available?
HPLC-based silymarin specifications such as 50%, 55%, 60%, and 80% can be reviewed according to project requirements. Buyers should confirm the target assay method and specification before comparing quotations.
Can you match an existing Silymarin specification or COA?
Yes. For replacement projects, providing the current COA or specification is usually the most reliable way to evaluate assay basis, quality limits, and technical comparability before sample testing.
