Here’s how Samsung’s Antioxidant Index feature will work with Galaxy Watches (APK teardown)
You will need to hold the back of your Galaxy Watch with your thumb to measure your body's beta carotene levels.
- Samsung’s upcoming Antioxidant Index feature will let you track your body’s beta carotene levels via your Galaxy Watch’s sensors.
- The watch must be removed and pressed against the thumb to perform the measurement, which then syncs with the Samsung Health app on the connected phone.
- Full compatibility details remain unclear, but you’d likely need One UI 8 Watch and a compatible Galaxy Watch, possibly the upcoming Galaxy Watch 8 series.
At the Galaxy S25 series launch, Samsung briefly mentioned an upcoming “Antioxidant Index” feature for the Samsung Health app, slated to arrive in 2H 2025. This feature will measure the beta carotene in your body and use this information to deliver personalized nutrition advice to ensure you are eating right. Beyond this, the company didn’t divulge more details. However, through a One UI 8 Watch leak, we had a fair idea of how the feature could work. Thanks to a new update to the Samsung Health app, we can corroborate how users can measure their beta carotene levels for the Antioxidant Index, and show the guidance pages present within the app.
