Advanced Glycation End-products (AGEs) are a class of harmful compounds that naturally form in the human body through a process called glycation. This occurs when sugars, such as glucose, react with proteins or lipids without enzymatic control. The process is similar to the browning reaction seen in cooked food (the Maillard reaction). Over time, these AGEs accumulate in tissues and organs, leading to significant cellular damage and functional impairment.
The continuous buildup of AGEs is closely associated with increased oxidative stress and inflammation, two key drivers of aging and numerous chronic diseases. High levels of AGEs have been implicated in the development and progression of serious conditions including, but not limited to, diabetes, cardiovascular disease (such as heart attacks and strokes), renal failure, and neurodegenerative disorders. Monitoring AGEs levels can therefore offer a valuable biomarker for assessing an individual's long-term health trajectory and disease risk.
The Samsung Galaxy Watch 7 and Galaxy Watch Ultra are at the forefront of integrating the AGEs Index, a sophisticated feature powered by innovative technology from Diagnoptics. This capability relies on Samsung's significantly upgraded BioActive sensor, which has been meticulously redesigned to enable this advanced form of health monitoring.
The measurement process is entirely non-invasive, leveraging optical measurement techniques. The BioActive sensor incorporates an array of LED wavelengths, including standard green and red LEDs, augmented by blue, yellow, violet, and ultraviolet LEDs. These specific light wavelengths are emitted through the skin to excite fluorescent markers known to be associated with AGEs accumulation within the body's tissues. The fluorescence emitted by these AGEs is then detected by the watch's sensors.
For optimal data collection, users are typically advised to wear the watch overnight. This allows the device to gather a "snapshot assessment" of AGEs levels in a consistent, undisturbed state. The collected data is then processed to generate an AGEs Index score, which is accessible through the Samsung Health app or directly on the smartwatch. This non-invasive approach provides a convenient and continuous method for monitoring this crucial health metric without requiring blood samples or specialized medical equipment.

The BioActive sensor is the technological cornerstone of the Galaxy Watch 7's advanced health tracking. Its enhanced design, with a broader spectrum of LED colors, allows for a more precise and comprehensive interaction with biological markers in the body. This multi-wavelength approach is critical for the accurate detection of AGEs, as different compounds and tissue properties interact with varying light spectrums. The sensor's ability to penetrate the skin non-invasively and detect the unique fluorescence signature of AGEs is what differentiates this feature, moving beyond traditional vital sign monitoring to offer deeper insights into cellular health and metabolic processes.
The AGEs Index on the Galaxy Watch 7 serves as a powerful biomarker for understanding two fundamental aspects of your health: your biological age and your overall metabolic health. Unlike chronological age, which is simply the number of years you've lived, biological age reflects the actual physiological condition of your body's cells and tissues. A higher AGEs Index suggests a greater accumulation of harmful glycation products, indicating that your body may be aging at an accelerated rate at the cellular level.
Furthermore, because AGEs levels are intricately linked to diet, lifestyle choices, and the risk of chronic diseases, the index provides valuable insights into your metabolic health. It can help identify potential risks for conditions such as type 2 diabetes and cardiovascular disease by monitoring factors like blood sugar control and inflammatory responses. This makes the AGEs Index a proactive tool for preventative health, encouraging users to make informed decisions about their lifestyle to potentially lower their AGEs score and support better long-term health.

The AGEs Index is integrated into the Samsung Health app, allowing users to view their score alongside other comprehensive health metrics. This holistic approach aims to provide a more complete picture of well-being, complementing data on sleep patterns, heart rate, body composition, stress levels, and the overall Energy Score.
However, it is crucial to recognize that the AGEs Index is currently categorized as an experimental "Labs" feature by Samsung. While it offers promising insights, users have reported some challenges in interpreting the results. Many have observed consistent or only slightly varying scores, often falling within a specific range (e.g., 7-8 out of 10) on the sliding scale. This consistency can sometimes make it difficult for users to discern what constitutes a "good" or "bad" reading, or how specific lifestyle changes might meaningfully impact their score. Samsung acknowledges the need for clearer guidelines to enhance the feature's utility and interpretability for the average user.
It is important to emphasize that the AGEs Index is intended solely for fitness and wellness purposes. It is not designed or validated for the diagnosis or treatment of any medical condition. Users should view it as an informative tool to monitor health trends and, if necessary, consult healthcare professionals for definitive medical assessments or guidance.
The Galaxy Watch 7 doesn't stop at AGEs monitoring; it offers a comprehensive suite of health and fitness tracking capabilities that, when combined, provide a robust overview of a user's health. These features include:
Many of these advanced features, including aspects of sleep tracking (like snoring detection) and AI insights, may require a Samsung phone for full functionality, and some medical-grade features like ECG, blood pressure, and sleep apnea tracking often necessitate the Samsung Health Monitor app.
