Affiliate & Medical Disclaimer

EVIDENCE BASED LONGEVITY ("we," "us," or "our") is committed to full transparency about how we make money, how we evaluate evidence, and what our content does and does not represent. The disclosures below are required by law and reflect our sincere commitment to operating honestly. Please read them carefully before relying on any content published on this Site.

FTC Affiliate Disclosure

In accordance with the Federal Trade Commission's guidelines on endorsements and testimonials (16 C.F.R. Part 255), EVIDENCE BASED LONGEVITY discloses that this Site contains affiliate links.

What this means: When you click a product link on EVIDENCE BASED LONGEVITY and make a purchase, we may receive a commission or referral fee from the merchant. This compensation comes at no additional cost to you — the price you pay is the same whether you use our link or navigate to the merchant directly.

Our current affiliate relationships include, but are not limited to, the following companies:

• Thorne Research — supplements and at-home testing products
• Life Extension — supplements, lab testing, and wellness products
• AgelessRx — longevity-focused prescription and OTC products
• Nordic Naturals — omega-3 and specialty supplements
• Other supplement brands and retailers whose products are reviewed on the Site

The existence of an affiliate relationship does not mean we recommend a product. We link to products we have independently reviewed based on the published scientific evidence. We do not link to products solely because an affiliate program exists, and we do not refuse to criticize products simply because we participate in their affiliate program.

Medical Disclaimer

Specifically, you should not:

• Use any content on this Site as a substitute for professional medical advice, diagnosis, or treatment.
• Start, stop, or adjust any medication, supplement, or health protocol based solely on information presented here without first consulting a physician or other qualified healthcare provider.
• Disregard professional medical advice or delay seeking it because of something you have read on this Site.
• Assume that any supplement rated highly on this Site is safe or appropriate for your individual health situation, as individual responses to supplements can vary significantly and depend on factors only your healthcare provider can assess.

The author of this Site is not acting in any clinical or prescriptive capacity in producing this content. No content on this Site creates a physician-patient relationship or any other form of professional-client relationship.

If you are pregnant, nursing, taking prescription medications, or have a pre-existing medical condition, consult your healthcare provider before using any supplement described on this Site. Some supplements have significant interactions with medications and contraindications in certain health conditions.

In the event of a medical emergency, call your local emergency number (e.g., 911 in the United States) immediately.

Evidence Rating Disclaimer

EVIDENCE BASED LONGEVITY applies a proprietary evidence-tier rating system to longevity supplements, compounds, and interventions. These ratings represent our independent assessment of the quality, consistency, and relevance of the published scientific literature — nothing more and nothing less.

Our evidence ratings are not:

• Evaluations by the U.S. Food and Drug Administration (FDA). The FDA does not evaluate or approve dietary supplements for safety or efficacy before they are marketed.
• Clinical recommendations, treatment guidelines, or endorsements from any medical or scientific body.
• Guarantees of safety, efficacy, or health outcomes for any individual.
• Statements that a supplement will prevent, treat, cure, or mitigate any disease or health condition.

How we assign evidence tiers: Our editorial team reviews peer-reviewed research — including randomized controlled trials, systematic reviews, meta-analyses, and observational studies — and applies a structured rubric that considers study size, methodology quality, replication across independent labs, relevance to human longevity endpoints, and recency of findings. Our methodology is described in detail on our Methodology page.

Scientific understanding of longevity and supplementation is rapidly evolving. A rating assigned today may not reflect findings published in the future. We endeavor to update ratings as significant new evidence emerges, but we cannot guarantee that all ratings are current at the time of your visit.

A high evidence tier indicates that a body of published research supports a hypothesis — not that the compound is definitively proven to extend human lifespan or improve health outcomes in every individual. Nutrition science and longevity research are inherently complex domains with many open questions.

Editorial Independence Statement

We believe that the value of EVIDENCE BASED LONGEVITY depends entirely on readers being able to trust that our ratings and content are not for sale. The following principles govern our editorial process:

• Affiliate relationships do not determine coverage. We do not review a supplement because a company has an affiliate program with us. We review supplements based on research significance, reader interest, and our own editorial judgment. We have affiliate relationships with brands whose products we have given unfavorable or mixed ratings.
• We do not accept payment for ratings. No company or individual may pay to improve a supplement's evidence tier, featured status, or ranking. Any request to do so will be declined and publicly noted if persistent.
• We do not accept sponsored reviews without clear disclosure. If we ever publish sponsored content — content for which compensation was received — it will be prominently labeled "Sponsored" or "Paid Partnership" and segregated from our independently produced reviews. As of the effective date of this disclosure, we do not accept sponsored reviews.
• Criticism is not suppressed by commercial relationships. If we identify meaningful risks, limitations, or evidence gaps in a product sold by one of our affiliate partners, we report them. Our obligation is to our readers, not to our commercial relationships.
• We disclose conflicts proactively. If a reviewer has a personal, financial, or professional relationship with a brand being reviewed, that reviewer is excluded from the editorial process for that review.

This editorial independence statement is made voluntarily and reflects our operating standards. It is not a legal guarantee. Readers who identify content they believe has been influenced by commercial factors are encouraged to contact us at arnoldsandlow@gmail.com.

No Third-Party Endorsement

References to specific brands, products, organizations, researchers, or publications on this Site do not imply that those parties endorse EVIDENCE BASED LONGEVITY, our methodology, or our ratings. All product names, trademarks, and registered marks are the property of their respective owners.

Citations to published research are provided for transparency and ease of verification. The authors or institutions whose work we cite have not reviewed or approved our interpretation of their findings. We make every effort to represent research accurately, but readers are encouraged to review the primary sources cited.

Limitation of Liability

To the fullest extent permitted by applicable law, EVIDENCE BASED LONGEVITY and its operator disclaim all liability for any direct, indirect, incidental, special, consequential, or punitive damages arising from:

• Your use of or reliance on any content, product, service, or recommendation on this Site;
• Any health outcome, adverse event, or interaction resulting from supplement use described or recommended on this Site;
• Inaccuracies or errors in our evidence summaries or ratings;
• Your use of any third-party website linked from this Site;
• Any interruption, suspension, or termination of the Site or its content.

This Site and all its content are provided on an "as is" and "as available" basis without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for certain types of damages. In such jurisdictions, our liability will be limited to the fullest extent permitted by law.
