DIRECT ANSWER
Which botanical ingredient is commonly evaluated for liver-support formulations?
Milk thistle extract is a common B2B candidate. Buyers should define the botanical identity, fruit or seed source, silymarin target and test method before comparing percentages. LongBio’s representative standardized grade is specified as 80% silymarin by UV; ratio extracts are separate purchasing specifications.
SPECIFICATION COMPARISON
Compare representative sourcing routes.
| Route | Definition | Method check | Formulation note |
|---|---|---|---|
| Milk thistle 80% silymarin | Standardized marker grade | Confirm UV assay and current-lot COA | Review solubility and dosage format |
| Milk thistle 10:1 | Ratio extract | Confirm ratio and identity | Do not compare ratio directly with assay percentage |
Specifications vary by grade and batch. The quotation, specification and offered-lot COA should describe the same material.

FREQUENTLY ASKED QUESTIONS
Liver-support ingredient sourcing FAQ.
Is 80% silymarin the same as a 10:1 extract?
No. One is defined by a marker assay and the other by an extraction ratio.
Why does the analytical method matter?
UV and HPLC may report different analytical targets or bases. The specification and COA should state the method.
Can buyers request samples and a current COA?
Provide the target grade, format, quantity and destination market so availability and documentation can be confirmed.
Does a raw material automatically support a finished-product claim?
No. Claims, dosage and regulatory suitability must be assessed for the final formula and destination market.
