Samsung’s Antioxidant Index on Galaxy Watch8 transforms what once seemed like science fiction into everyday technology. In five seconds, a thumb scan returns carotenoid levels – the industry’s first measurable nutrition index[1].

By miniaturizing lab-grade sensor technology, it turns your diet into an actionable metric for healthier aging. Establishing this new benchmark in wearable health tracking required years of intensive R&D, countless prototypes, and unwavering grit.

Breaking New Ground in Nutrition Tracking

Back in 2018, Samsung saw a critical gap in wearables: we could count every step and calorie, yet there was no simple way to measure how our diet impacted our health. Deeper nutritional insights were locked behind expensive and time-consuming lab tests, out of reach for many people.

As people live longer, the focus is shifting from simply increasing lifespan to improving the quality of those additional years.

“In this context, antioxidation naturally gains attention as a method to slow down aging,” explains Dr. Hyojee Joung, a Seoul National University public health nutrition expert who guided parts of the tech’s development. “If antioxidant management is neglected, Reactive Oxygen Species (ROS) accumulate in the body, increasing the risk of chronic diseases such as cardiovascular disease, diabetes, and cancer.”

This realization made antioxidants the cornerstone of Samsung’s mission. Engineers and scientists focused on carotenoids – key antioxidants and indicators of fruit and vegetable intake – to create a device small enough to sit on your wrist, yet powerful enough to turn complex antioxidant data into simple, actionable insights for everyone.

Challenge #1: How to Shrink the Lab-Grade Sensor Technology

From day one, the dream of a nutrition-tracking wearable hit an immediate snag: traditional methods for measuring carotenoid levels like Raman spectroscopy are laser-based, non-invasive and precise, but rely on bulky machines that are far from wearable. So the team’s first mission was to shrink the lab-grade tech into a coin-sized sensor.

3. A prototype designed for use in skincare products

After seven years of rigorous testing and optimizing since the first prototype, the team developed the BioActive sensor, a groundbreaking tech that combines multi-wavelength LEDs with a custom photodetector array to provide – carotenoid readings in a compact design.

“Our breakthrough was integrating reflectance spectroscopy with LEDs, which allowed us to miniaturize the technology while maintaining a high level of accuracy,” explains Jinyoung Park, a developer from Digital Health team at Samsung Electronics.

Unlike lasers, which emit a sharp, narrow wavelength, LEDs emit a broader wavelength range. By analyzing how much light is absorbed by the skin at multiple wavelengths through photodiodes, the watch estimates carotenoid levels. The advanced algorithms that continuously calibrate in real-time also support precision while delivering personalized insights to each user.[2]

Challenge #2: How to Ensure the Tech Reaches Everyone

Creating a coin-sized carotenoid sensor was a major milestone, but the next challenge was ensuring it could work accurately and reliably across diverse skin types, making it truly accessible to everyone.

To overcome challenges like melanin interference in darker skin tones, Samsung’s engineers opted to use the fingertip for measurements since it has the least melanin across all ethnic groups. They also added simple tweaks, like light fingertip pressure during scans, which helps temporarily reduce blood flow and hemoglobin interference.

Extensive trials conducted at Samsung Medical Center, included hundreds of participants, validating the sensor’s performance. This paved the way for a feature that seamlessly transitioned from the lab to users worldwide, offering an inclusive solution designed for everyday life.

How it Works:

Carotenoids are the natural red, yellow, and green pigments found in fruits and vegetables. Since our bodies can’t produce carotenoids on their own, the levels stored in the body offer a snapshot of how much fruit and vegetables someone has been eating.

This is where your Antioxidant Index score comes in, reflecting your carotenoid levels based on these categories:

• Very low: Less than 50% of the daily WHO recommendation of 400g per day.
• Low: Between 50%–100%.
• Optimal: 100% or more.

“Skin carotenoids metabolize and accumulate in tissues gradually, so short-term changes in fruit and vegetable intake won’t immediately appear in the score,” explains Dr. Hyojee Joung. “Our research shows that increased carotenoid intake leads to a meaningful rise in skin carotenoid levels after about one to two weeks, making the Index a valuable tool for tracking consistent, long-term dietary habits.”

Lifestyle factors like sleep quality, stress levels, and physical activity also influence the Index, making it a well-rounded indicator of overall wellness. Paired with other Galaxy Watch8 features like sleep coaching[3], activity tracking and Vascular Load monitoring[4], the Antioxidant Index offers a holistic view of your wellness, empowering smarter decisions.

The Antioxidant index feature measures carotenoid levels in seconds with the sensor on the back of the Galaxy Watch8 and provides additional nutritional insights on paired Galaxy smartphones.

Your Wellness, Reimagined

“New wearable sensors can play a role in helping people build healthy eating habits by tracking and encouraging sufficient daily intake of fruits and vegetables,” says Professor Yoonho Choi from Samsung Medical Center.

Antioxidants are an emerging area of focus, and research has been limited due to the challenges of accurate measurement. But Galaxy Watch8’s Antioxidant Index goes beyond current industry developments and delivers meaningful innovation.

Samsung’s ability to measure antioxidant levels is a game-changer in health monitoring. By helping users identify risks early and take proactive steps towards improving their wellness, Samsung is paving the way for a smarter, more proactive approach and reimagining what role wearables can play.

Powered by Samsung’s innovative sensor technology, the new Galaxy Watch8 series¹ provides a holistic, real-time overview of our health. It provides clear, insights based on your lifestyle patterns to help you understand your body and mind more deeply, build healthy habits and help monitor for heart beat irregularities.

▲The Galaxy Watch8 series’ Antioxidant Index allows you to monitor your antioxidant intake by measuring carotenoid levels in the skin.

Monitor your Heart Health

With new heart metrics, Galaxy Watch8 series spots the potential for health issues sooner and allows you to monitor your heart.

• Irregular Heart Beat Detection: Galaxy Watch8 series’ enhanced Electrocardiogram (ECG)² and the Samsung Health Monitor app can detect irregular rhythms. Galaxy Watch8 series provides ECG measurement with the ability to differentiate instances of irregular rhythms providing insights on your heart.
• Vascular Load³: While you sleep, Galaxy Watch8 series’ reads Photoplethysmogram (PPG) waveforms – optical signals associated with blood flow during sleep. It measures blood volume and vascular stiffness and analyzes changes in stress on blood vessels. Because diet, stress, and rest all affect this metric, regular monitoring can show which habits to fine-tune.

Lifestyle Changes Motivated by Sensor-Driven Insights

The Galaxy Watch8 series’ advanced sensor now gives you more insights for your nutrition and sleep patterns to steer you towards lasting, sustainable habits:

• Antioxidant Index⁴: The Galaxy Watch8 series shines a light on your daily choices. The BioActive Sensor measures skin carotenoids in five seconds using multi-wavelength absorption spectroscopy. After analyzing these carotenoids, an antioxidant which reflects fruit and vegetable intake, you are given a score of 0–100, which is categorized into one of three levels. This score shows how diet, UV light, alcohol and stress are impacting your antioxidant levels. With insufficient fruit and vegetable intake linked to major health risks, this non-invasive metric offers meaningful insight and can lead to making healthier choices.

• Bedtime Guidance⁵: Leveraging the science behind the two-process model of sleep regulation, the Galaxy Watch8 series tracks your circadian rhythm (internal body clock) and sleep pressure (how much your body needs sleep), over three days. It then interprets this data as a differential equation to calculate the optimal bedtime for waking up refreshed. The algorithm uses changes in sleep threshold and individual sleep needs throughout the day to deliver personalized guidance. Developed by Korea Advanced Institute of Science & Technology (KAIST), this feature helps build healthier sleep routines that lead to deeper, less interrupted sleep and more energized mornings.
