Samsung has introduced an advanced feature called the Antioxidant Index within its Samsung Health app, designed to measure beta carotene levels through the skin. This groundbreaking functionality will likely debut on a future Galaxy Watch model, possibly the Galaxy Watch 8. Users will need to press their thumb firmly onto the watch sensor for non-invasive measurements. The feature aims to provide personalized nutrition advice based on individual beta carotene readings.

According to leaked information from One UI 8 Watch APKs, the Antioxidant Index will offer users insights into their daily averages and whether their beta carotene levels are adequate or low. It is emphasized that this tool should not be used for medical diagnosis but rather as a fitness and wellness aid. Samsung plans to release this feature in the second half of 2025, although specific device compatibility remains undisclosed.

Non-Intrusive Measurement Process

The Antioxidant Index feature leverages cutting-edge technology integrated into compatible Galaxy Watches, allowing users to measure beta carotene levels effortlessly. By pressing their thumb against the watch's sensor, individuals can initiate a seamless and painless assessment process. This method ensures accurate results while maintaining user convenience.

To achieve precise measurements, users are advised to utilize their thumb instead of their wrist, ensuring optimal contact with the sensor. Additionally, measurements should be spaced at least ten seconds apart to allow sufficient time for data processing. Connectivity between the watch and phone is crucial, enabling users to monitor progress directly on their mobile devices. Graphics accompanying the feature provide clear visual instructions, enhancing user understanding and interaction with the system.

Purpose and Limitations of the Antioxidant Index

Beyond offering beta carotene level assessments, the Antioxidant Index delivers tailored nutritional recommendations aimed at promoting healthier lifestyles. This feature categorizes readings as either adequate or low, providing users with actionable insights into their dietary habits. As part of Samsung Health's Labs section, it signifies ongoing development and refinement of the tool.

While highly beneficial for general fitness tracking, the Antioxidant Index explicitly disclaims suitability for diagnosing or treating medical conditions. Individuals concerned about their antioxidant levels are encouraged to consult healthcare professionals for comprehensive evaluations. Scheduled for release in late 2025, the feature aligns with potential updates to One UI 8 Watch, suggesting compatibility requirements may involve the latest iterations of both the Galaxy Watch series and Samsung Health application. This integration underscores Samsung's commitment to advancing wearable health technologies, empowering users to take proactive steps toward better well-being.
