It uses the health sensor on the Galaxy Watch to non-invasively measure beta-carotene levels, helping users tailor their nutrition. Samsung is clear that this is not meant to diagnose medical conditions. To measure, press the pad of your thumb firmly on the center of the sensor on the back of your watch. You can check measurement progress on your phone. For more accurate results, measure with your thumb, not your wrist, and space out measurements by at least 10 seconds. Make sure your watch is connected to your phone. Check the progress of the measurement on your phone. Place your thumb on the sensor and press firmly. ”Keep in mind that antioxidant index measurement is for fitness and wellness only, not for the diagnosis or treatment of any medical condition. If you’re concerned about your antioxidant level, be sure to see a medical professional.” Caption - Graphics of One UI 8 Watch update.
