The Obsidian Review is an independent affiliate supplement review platform. We publish assessments in the margins of supplement marketing — noting what's verified, what's plausible, and where the evidence falls short.
We research supplements using publicly available information: manufacturer claims, third-party testing status, ingredient research, and pricing structure. We write our findings plainly and we disclose our financial relationships explicitly.
We earn commissions when readers purchase through our affiliate links. This is disclosed prominently on every page, per FTC guidelines. Our commissions do not change our assessments, but they are a real financial interest you should factor into how you read our writing.
