Editorial policy
Clearhead Lab publishes evidence-based reviews. Every medical or efficacy claim is tied to a primary source (peer-reviewed research or official labeling). We disclose affiliate relationships. They never change what we write about a product or the facts we report — but they do bear on placement, which we spell out in our affiliate disclosure. Corrections are made promptly and noted.
What our reviews establish
Provider reviews compare published product information, fees, billing commitments, refund policies and care disclosures. Reading these documents cannot establish an individual patient's eligibility, delivery experience or treatment outcome. We identify those limits in the review rather than presenting website research as firsthand testing.
Evidence and clinical interpretation
A finding about an ingredient, biomarker or delivery route does not automatically apply to a finished product or to a symptom. We distinguish human outcomes from laboratory mechanisms, explain study limitations and keep urgent-care advice separate from product comparisons. An editorial source check is not a clinical assessment.
Updates and corrections
The update month reflects changes to the article. Prices and policies can change afterward, so confirm the actual supply, total charge and renewal terms with the provider before purchasing. Report a correction with the page URL and supporting source to mail@clearheadlab.com.
Who applies these rules, and the background they are applied with, is on the page about this site and its editor. And because a well-sourced article is still not a diagnosis, the boundary between what we publish and actual medical care is drawn in the medical disclaimer, which is worth reading before you act on anything here.
