Affiliate & Commercial Disclosure
Last updated: October 2026 • Compliant with Federal Trade Commission Disclosure Requirements
Core Commercial Separation Principle
HCD Health participates in affiliate marketing programs. When you click links on our site (including our internal redirect system at /go/[slug]) and complete a purchase, we may earn an affiliate commission at no additional cost to you. However, commercial partnerships have zero influence on our clinical ratings, evidence grades, or editorial verdicts.
1. Why We Use Affiliate Links
Conducting comprehensive biomedical research, underwriting physician review honoraria, and maintaining ad-free publication infrastructure requires sustainable financing. Affiliate commissions allow us to keep our deep-dive monographs free and completely ungated without running intrusive third-party display advertisements or selling reader data.
2. Redirection Mechanism & Transparency
Outbound merchant referral links are routed through our internal redirect handler:
Every redirect applies rel="nofollow sponsored" tags to comply with search engine webmaster guidelines and FTC endorsement mandates.
3. Editorial Veto & Uncompromised Evaluation
Our clinical reviewers are never informed of commercial terms or affiliate revenue metrics. A product that offers high commercial commissions will still receive a failing evidence grade (Grade C or D) if its formulation fails clinical substantiation.
