Medical disclaimer
What our health content can and cannot do, and when to talk with a clinician.
Last updated October 2026
This article is for general information only and is not medical advice. Supplements can interact with medications and health conditions. Talk with a qualified clinician before starting, stopping, or changing any supplement.
Not a substitute for care
Our articles are general information, not a diagnosis, treatment plan, or prescription. We do not know your medical history, medications, allergies, pregnancy status, or test results. A product that is appropriate for one person may be inappropriate or unsafe for another.
Talk with a qualified clinician before use
This is especially important if you:
- take prescription medicine, including blood thinners, blood pressure medicine, or diabetes medicine;
- are pregnant, planning a pregnancy, or breastfeeding;
- have a liver, kidney, heart, thyroid, or bleeding disorder;
- are preparing for surgery;
- are shopping for a child or an older adult.
About health products
Home health products can be useful, but they are not a replacement for a clinical measurement. A single reading can be wrong. If a device reading is alarming, or if you have symptoms, contact a clinician or emergency service rather than relying on the device alone.
About supplements
Supplements are regulated differently from medicines in many countries. Labels can be inaccurate, doses can vary, and “natural” does not mean risk-free. Look for third-party testing when possible, and tell your clinician about everything you take.
Emergency
If you think you are having a medical emergency, call your local emergency number immediately. Do not wait for a reply from this website.
