This website exists to inform people about Purisaki Berberine Patches and the research behind our ingredients. We take that responsibility seriously. Everything published on this site is subject to the standards described below before it goes live.
Every factual claim about an ingredient's mechanism or effect is cross-referenced against primary research — ideally randomized controlled trials, meta-analyses, or systematic reviews indexed on PubMed. Where we cite a study, we link directly to its PubMed abstract so readers can verify the claim themselves. We do not hide our sources behind vague phrases like "studies show."
All content on this site related to ingredients, mechanisms, or metabolic health topics is reviewed by Dr. Marcus Chen, MD, our metabolic health advisor. Dr. Chen is a licensed physician specializing in metabolic health. His review does not constitute medical advice to any individual reader — it is a check on scientific accuracy and appropriate framing.
Disease claims. Purisaki Berberine Patches are a dietary supplement, not a drug. We will not claim the product treats, cures, or prevents type 2 diabetes, obesity, metabolic syndrome, cardiovascular disease, or any other condition. Such claims would be both legally prohibited and scientifically dishonest.
Manufactured testimonials. We do not fabricate customer reviews or pay for testimonials framed as organic. The reviews displayed on this site reflect common patterns from real customer feedback, edited for clarity.
Results guarantees. We cannot and will not promise specific weight-loss outcomes or blood-sugar changes. Individual results vary. What we guarantee is the 60-day money-back refund if the product does not work for you.
Hidden advertising. This website is operated by the Purisaki team, and product links are our own affiliate/sales links. That relationship is disclosed throughout the site and is not hidden.
We are careful, but not infallible. If you spot an error of fact or citation on this site, please email support@purisaki.com. Corrections are made promptly and, when material, noted on the page.
Ingredient research evolves. When new evidence emerges — positive or negative — affecting claims on this site, we update the relevant content. The "Last Updated" date on each page reflects the most recent revision. We do not retroactively remove disclosed limitations; we add new information.
Primary author and medical reviewer for this site is Dr. Marcus Chen, MD — a metabolic health physician with focused experience in integrative approaches to insulin resistance, blood sugar balance, and weight management. Any article on this site that describes mechanisms, research findings, or health-related content has been reviewed by Dr. Chen before publication.
The content on this site is educational. It is not individualized medical advice. Readers who are pregnant, nursing, under 18, managing a diagnosed condition, or taking any prescription medication should consult their own healthcare provider before starting any supplement — including ours.
