Samsung is set to launch a new feature called Antioxidant Index, which will measure beta carotene levels, and leaked guidance pages have provided insight into its functionality and additional details.

Recently, Samsung confirmed that it is developing the Antioxidant Index feature for the Samsung Health app, with plans to introduce it in the second half of 2025 on the Galaxy Watch 8 series.

The Antioxidant Index feature aims to measure the body’s carotene levels and offer personalized nutrition advice, allowing users to optimize their diet by tracking antioxidant intake.

According to reports, measuring beta carotene levels using the Antioxidant Index feature will require a Galaxy Watch. A recent report from Android Authority has leaked the guidance pages for the feature, providing details on its functionality.

The leaked pages reveal that the feature can help prevent chronic illnesses by eliminating free radicals and reducing oxidative stress. It also enables users to track their daily intake of fruits and vegetables. The feature measures carotene levels in three categories, including the antioxidant index level, which is displayed on the Galaxy Watch screen in both full and half tile sizes.

As per the leaked guide page, users will need to connect their Galaxy Watch to their phone and then press their thumb firmly on the sensor at the back of the watch. The measurement progress can be tracked on the phone via the Samsung Health app.

Samsung has not yet clarified whether the Antioxidant Index feature will be compatible with older Galaxy Watch models or exclusive to newer devices.
