Galaxy Watch8: Breaking New Ground in Real-Time Nutrition Tracking
In 2018, Samsung noticed something missing in wearable health tech. We could track steps, sleep, and calories — but not how our diet affects our body in real-time. Nutrition insights required expensive lab tests, making them inaccessible to most. With the Galaxy Watch8, that gap finally closes. Samsung introduces the world’s first Antioxidant Index, a feature that measures nutrition levels directly from your wrist — turning futuristic science into everyday wellness.
Why the Galaxy Watch8 Focuses on Antioxidants
As people live longer, health goals are shifting from longevity to quality of life.
“In this context, antioxidation naturally gains attention as a way to slow aging,” says Dr. Hyojee Joung from Seoul National University. “Neglecting antioxidant management allows Reactive Oxygen Species (ROS) to accumulate, increasing risks of diabetes, cancer, and heart disease.”
This understanding drove Samsung’s mission — to make antioxidant tracking accessible and simple with Galaxy Watch8’s Antioxidant Index.
How Samsung Miniaturized Lab Tech for Galaxy Watch8
Traditional Raman spectroscopy used in labs is laser-based and bulky — impossible to wear. Samsung’s challenge was to miniaturize this precision tech.
After seven years of innovation, engineers achieved a major breakthrough. The Galaxy Watch8 now uses reflectance spectroscopy with multi-wavelength LEDs and a custom photodetector array.
“Our breakthrough was integrating reflectance spectroscopy with LEDs,” explains Jinyoung Park from Samsung’s Digital Health team. “It allowed us to shrink the technology while maintaining accuracy.”

Inclusive Health for Everyone
Accuracy was essential — but so was accessibility. Samsung wanted the Galaxy Watch8 Antioxidant Index to work reliably across all skin tones.
To solve melanin-related interference, engineers designed the sensor to scan from the fingertip — an area with the least melanin. Light fingertip pressure helps reduce hemoglobin effects, improving accuracy.
Extensive clinical trials at Samsung Medical Center confirmed the sensor’s reliability across diverse participants. The Galaxy Watch8 is now equipped to deliver inclusive health insights worldwide.
Understanding the Galaxy Watch8 Antioxidant Index
Carotenoids are natural pigments found in colorful fruits and vegetables — vital antioxidants our bodies can’t produce. Measuring them reveals how nutritious your diet is.
Your Antioxidant Index score on the Galaxy Watch8 falls into three categories:
- Very Low: Below 50% of WHO’s 400g daily fruit and vegetable target
- Low: Between 50%–100% of the target
- Optimal: 100% or more
“Carotenoid levels rise gradually with consistent intake,” says Dr. Joung. “You’ll see changes after about one to two weeks.”
Lifestyle factors like stress, sleep, and exercise also affect the Index, making it a holistic wellness marker. Combined with Watch8 features like Sleep Coaching, Activity Tracking, and Vascular Load, it creates a complete health ecosystem.
Galaxy Watch8: Shaping the Future of Healthy Living
“Wearable sensors can motivate healthier eating by tracking fruit and vegetable intake,” says Professor Yoonho Choi from Samsung Medical Center. “This can help prevent cancer and age-related diseases.”
By transforming lab technology into a five-second fingertip scan, Watch8 redefines personal health tracking. It empowers users to take control of their wellness, identify risks early, and make better lifestyle choices.
The Watch8 Antioxidant Index sets a new global benchmark — combining innovation, inclusivity, and precision to revolutionize the future of health wearables.
