All content on this website — including research summaries, articles, guides, test results, and product discussions — is provided for general informational and educational purposes only. Nothing on this site is intended as medical advice, diagnosis, or treatment.

Using this website does not create a doctor-patient relationship between you and Longevity China, its team, or any contributors. Our content is not a substitute for a personal consultation with a qualified healthcare professional.

Before making any changes to your diet, exercise routine, supplement regimen, or medical treatment, please consult a qualified healthcare professional who knows your individual medical history. Information on this website should never delay or replace professional medical evaluation, especially when you experience symptoms or health concerns.

If you are pregnant or breastfeeding, under 18, over 65, have a diagnosed medical condition (including but not limited to cardiovascular disease, diabetes, autoimmune disorders, kidney or liver disease), or are taking prescription medication, consult your physician before applying any information, recommendation, or product mentioned on this website. Some interventions discussed here (including cold exposure, fasting, intense exercise, and certain supplements) carry specific risks for these groups.

Our age tests, biomarker estimates, and wellness tools (including but not limited to the Photo Age Test, Pace of Aging Test, rPPG heart rate and HRV scanner, vascular age estimate, and all in-person Longevity Check measurements) provide educational estimates only, based on statistical models, computer-vision algorithms, or self-reported inputs. These tools are explicitly not medical devices within the meaning of the EU Medical Device Regulation (MDR 2017/745) or comparable national regulations. They are not certified for diagnostic purposes, have not undergone clinical validation, and cannot replace laboratory tests, professional medical examination, or clinical assessment. Results may show significant variation between sessions, devices, and lighting conditions. They should not be used to make medical decisions, to monitor a known medical condition, or as a basis for self-medication. If a result concerns you, consult a qualified healthcare professional rather than acting on the value alone.

Mentioning a treatment, supplement, test, device, or product on this site does not constitute an endorsement or recommendation. Product discussions are informational — always consult a healthcare professional before starting any new supplement or treatment.

Our research section presents summaries of published, peer-reviewed studies. These summaries are simplified for a general audience and may not capture every nuance of the original publication. We link to the original source (DOI) wherever possible so you can review the full study. Evidence ratings reflect our editorial assessment and are not a guarantee of clinical applicability.

Our platform allows community members to share their personal experiences, supplement stacks, routines, and recommendations. Such user-generated content reflects the personal opinions and choices of individual members and does not represent medical advice, professional opinion, or endorsement by Longevity China. We do not verify the accuracy or safety of user-generated content. Always evaluate community contributions critically and consult a healthcare professional before adopting practices shared by other members.

We make every effort to present accurate, up-to-date information based on peer-reviewed research. However, we cannot guarantee that all content is complete, current, or free from error. Longevity science is a rapidly evolving field — findings may change as new evidence emerges.
