Nuestra Metodología

1. Testing & review protocol

Products are categorised as hands-on tested or catalog only. Hands-on tested products are sourced through retail or manufacturer channels (never from affiliate-program promo samples), used by an editor for a minimum of 30 days under consistent stack conditions, and audited against label claims via a clinical-dose cross-reference. Catalog-only products are evaluated from manufacturer-published ingredient lists, regulatory filings, and third-party Certificates of Analysis when available. Every listicle pick and comparison row is tagged so readers can self-filter trust. We never imply hands-on testing where none has occurred.

2. Conflict-of-interest policy

We earn affiliate commissions from links on commercial pages. Affiliate relationships do not influence:

• 5-pillar scores (set before any affiliate program is evaluated)
• Listicle ranking position (driven by score + use-case fit only)
• Pros/cons content (criticism is preserved even on affiliate-active products)
• Clinical-dose audit verdicts (purely data-driven against PubMed-indexed RCTs)

We do not accept payment for reviews, sponsored content placements, or guaranteed-position promotion. Affiliate disclosures appear at the top of every commercial page, before the first call-to-action, in compliance with FTC 16 CFR Part 255 (US), ASA CAP Code (UK), and equivalent advertising codes in each region we publish.

3. Source-citation policy

Clinical-dose claims are sourced from PubMed-indexed human randomized controlled trials, meta-analyses, and Examine.com syntheses. Regulatory claims are sourced from primary regulator documents (FDA, EFSA, TGA, Health Canada, MHLW Consumer Affairs Agency, ANMAT, ANVISA, COFEPRIS, SFDA, BPOM, HSA, NPRA, JAKIM, BPJPH). When a claim cannot be sourced from primary literature or a primary regulator, it is either omitted or flagged as "limited evidence" / "manufacturer claim only". We do not cite secondary aggregators (Healthline, Verywell) as primary sources for clinical claims.

4. Correction policy

We aim to respond to substantive editorial corrections within 5 business days and to update or retract incorrect content within 10 business days of verification. When a correction is made:

• The page's dateModified Article-schema field is updated to reflect the change.
• For factual corrections (dose values, regulatory status, brand ownership), the prior statement is replaced and a brief note is added to the page when the correction is material to a reader's purchase decision.
• We do not silently delete published claims. Significant corrections to scored comparisons trigger a re-score under the same 5-pillar framework with a visible date.

Send corrections to [email protected]. Include the page URL, the specific claim, and a primary source supporting the correct version.

5. Editorial-team identity

The Nootropic Lab operates as an independent editorial collective. Reviews are produced collaboratively by editors with backgrounds in pharmacology, evidence synthesis, and consumer-product analysis. We do not disclose individual contributors by name and do not feature personal brands within reviews. This is a deliberate choice: it keeps the focus on the methodology and the data, and reduces the risk that a single contributor's preferences disproportionately influence rankings. Every review applies the same 5-pillar framework documented above; consistency is the credibility signal, not authority by persona.

6. Region-specific regulatory framing

Each regional edition of this site applies the YMYL disclaimer language mandated or expected by that region's primary regulator: DSHEA (US FDA), Reg (EC) 1924/2006 + EFSA register (EU), Health Canada NPN (CA), TGA Therapeutic Goods Advertising Code (AU), PMD Act + FFC + FOSHU (JP), ANVISA / COFEPRIS / ANMAT (LATAM, with explicit ANMAT 2105/2022 banned-compound auditing for Argentine traffic), SFDA + Halal certification (GCC), HSA + BPOM + NPRA + Halal mandatory ID/MY (SEA). Cognitive claims that are not approved by the relevant regulator are reframed as ingredient mechanisms or consumer experience and never asserted as label-grade health claims.
