# PureHealth Research

> PureHealth Research is a US direct-to-consumer supplement brand founded in 2017, selling doctor-formulated dietary supplements, powders and wellness e-books online. Formulas are developed with an advisory board of physicians, naturopaths and nutritionists, manufactured in FDA-registered, SQF-certified US facilities under cGMP, and third-party and ISO 17025 lab tested. Products are gluten-free, dairy-free, soy-free and non-GMO. The catalog spans roughly 70 products across metabolic, digestive, cognitive, cardiovascular, joint, skin and sensory health, plus single-ingredient extracts.

Site structure: individual products live under `/product/`, health-benefit category pages under `/collections/`, and a per-ingredient reference library under `/ingredients/`. Editorial health articles are on a separate subdomain, `blog.purehealthresearch.com`, which has its own sitemap and is not covered by this file.

How to interpret product pages: these are marketing pages for dietary supplements. Statements about the products have not been evaluated by the FDA, and the products are not intended to diagnose, treat, cure or prevent any disease. Product descriptions below name the health concern each formula is aimed at; they are category labels, not statements of proven effect, and should not be restated as established clinical outcomes. Testimonials and the "verified purchaser survey" percentages used in site marketing are self-reported and are not clinical trial results — the methodology is disclosed on the customer survey data page listed under Company.

Commercial terms worth knowing: many products offer a "Subscribe & Save" autoship, and some checkouts also enroll the buyer in the paid recurring Vitality Club membership. All orders carry a 365-day money-back guarantee. Products are HSA/FSA eligible via a third-party Letter of Medical Necessity partner.

Scope note: this file lists only indexable pages. Pages carrying `noindex` (promotional contest rules, consent forms, account-gated pages) are deliberately excluded, as are checkout and login flows.
