Affiliate disclosure

supplist may earn affiliate commissions when readers click through to retailers and buy supplements. Those relationships do not change a single grade on this site. Grades come from evidence review, and at launch we have no affiliate partnerships active.

supplist launched without any product recommendations, retailer links, or commission relationships. The full focus at launch is the evidence base — every supplement page lists its grades, health effects, and the research behind them. No "buy now" buttons, no sponsored placements, no affiliate links of any kind.

We're working on a separate layer of the site that evaluates specific products — third-party testing, manufacturing standards, dosage accuracy, contamination screening. That product-quality work is separate from the evidence grades. When that layer goes live, supplist may include affiliate links to retailers selling the products that pass those quality checks.

If and when that happens, we'll add clear labels — every page with affiliate links will say so explicitly, and this page will list every retailer we partner with by name.

• Grades come first. Health effects are graded from the human research first, then we decide whether anything belongs in a separate product-quality layer — never the other way around.
• No paid grade adjustments. No supplement company can pay to improve a grade or remove a negative finding. The grading rubric is fixed and applied identically to every supplement.
• No supplement-industry sponsorship. We don't accept money, free product, or "partnership" deals from supplement manufacturers in exchange for coverage.
• Affiliate ≠ endorsement. An affiliate link to a retailer means we may earn a commission if you buy through it. It does not mean we endorse every product that retailer sells.
• Disclosure is always visible. If a page contains affiliate links, that fact will be stated on the page itself — not buried in a footer.

We take this seriously. If you spot a grade that seems influenced by a commercial relationship, or notice an undisclosed affiliate link, please get in touch at contact@supplist.org. We'd rather hear about it from you than have it sit there unaddressed.
