About
CleanIngredients is a public directory for US supplement brands comparing plant-extract manufacturers in China. The first pages cover lutein, rhodiola, fisetin, and curcumin / turmeric extract.
Listings are free to read. A sourcing inquiry, a sample request, and a quote request are free to submit. A supplier cannot buy a higher rank.
The public-evidence transparency score counts documents: site address, lot COAs, registry certificates, botanical identity, extraction method, contaminant methods and limits, standardisation, assay, and a published specification. It does not measure safety or quality. CleanIngredients does not independently test the suppliers in this version.
Requests are stored for staff to review. They are not sent to suppliers by the form. A sourcing inquiry does not select a supplier. Contact details from a sample or quote request are shared with the selected suppliers only after that review.
Older articles under Information remain online as an archive. They are not the scoring method. Use the methodology for anything about a score or an eligibility decision.
The buyer guides explain grade-specific purchasing questions. The free tools show their assumptions and formulas. The coverage report distinguishes our research footprint from supplier eligibility. Duplicate archive URLs are consolidated into the completed guide. Public article pages and the sitemap point to the maintained versions.
What the current service includes
CleanIngredients is a research directory, not a marketplace checkout or a laboratory. We do not independently test, audit or certify suppliers, process ingredient payments, insure shipments, or issue refunds for supplier orders. Older descriptions of those services do not describe the current directory.
Submitting an inquiry is free. Suppliers may charge for samples, shipping and materials. Buyers agree purchase and dispute terms directly with their supplier. A research lead is not a confirmed offering, and document coverage is not an approval.
Corrections are welcome on the contact page.
