For the first time in a smartwatch, the Galaxy Watch8 series introduces Antioxidant Index — a feature that measures antioxidant levels to show how diet and lifestyle impact health.

Building on insights from part one with Hyojee Joung of Seoul National University, Samsung Newsroom spoke with Jinyoung Park of the Health H/W R&D Group, Mobile eXperience (MX) Business at Samsung Electronics, to discuss how the Galaxy Watch8 series’ sensor was developed.

From Food Logs to a Five-Second Scan

Tracking meal quality and nutrient intake has typically required detailed food logs or blood tests. With the Galaxy Watch8 series, users can instead press a thumb against the back of the device for about five seconds to measure carotenoid¹ levels in the skin — displayed as an Antioxidant Index.

At the core of this process is Samsung’s advanced BioActive Sensor. “The sensor uses multi-wavelength absorption spectroscopy, shining light of various wavelengths onto the skin and analyzing the absorption and reflection patterns,” said Park. “The Galaxy Watch8 series is the first wearable to measure organic compounds in the body through skin absorption spectra.”

Carotenoids are electron-rich compounds made up of 40 carbon atoms that strongly absorb blue light — the principle behind Antioxidant Index. When the sensor emits yellow, blue, purple and green LED light, carotenoids absorb some wavelengths and reflect others. By analyzing the reflected light, their concentration can be measured. “Consistent consumption of fruits and vegetables leads to greater carotenoid accumulation in the skin, causing the index to rise,” she added.

Skin spectra also include signals from melanin and hemoglobin. “To minimize these effects, we chose the finger as the measurement site to reduce melanin interference and applied a pressing method to momentarily restrict blood flow and lessen hemoglobin’s impact,” Park explained. Even the simple act of pressing a thumb against the sensor reflects careful design and extensive consideration.

Miniaturizing Accuracy

Samsung began researching sensors for Antioxidant Index in 2018. The challenge was building a sensor small enough for a watch yet accurate enough to rival large laboratory equipment.

“Even the slightest change in the arrangement of LEDs and photodiodes could affect results,” Park recalled. “We conducted countless tests to find the optimal configuration.”

To ensure accuracy, the team validated the sensor using Raman spectroscopy — a laser-based technique widely used in research and clinical settings to detect the accumulated amount of skin carotenoids by measuring molecular vibrations. “Raman spectroscopy requires large, complex equipment, making it impractical for daily use,” she explained. “In the Galaxy Watch8 series, we applied skin reflection method based on LED-PD to miniaturize the sensor and improved accuracy by cross-checking results with Raman spectroscopy.”

The team also ran comparative studies with blood tests and clinical trials. “We validated the accuracy of noninvasive measurements by comparing carotenoid levels in blood with sensor readings,” said Park. “Clinical participants photographed and logged every meal for a week, allowing us to compare their fruit and vegetable intake against the sensor data. With a statistically significant sample of several hundred participants, we scientifically verified the sensor’s performance.”

Park stressed that collaboration was key to development. “In addition to long-standing work with Joung, we conducted clinical research with Samsung Medical Center and partnered with the University of Connecticut to collect data from diverse ethnic groups,” she added. “Experts in nutrition, medicine and consumer analysis formed a close network of collaboration that made commercialization possible.”

Getting the Most Out of Antioxidant Index

How often should Antioxidant Index be measured? “It usually takes two to three weeks for carotenoids from food to build up in the skin to detectable levels,” Park explained. “We recommend maintaining consistent healthy eating habits for at least two weeks and measuring once or twice a day at the same time.”

The Samsung Health app provides dietary tips based on Antioxidant Index and displays changes in clear reports. Users can view daily, weekly, monthly and yearly data to monitor health and lifestyle patterns over time.

Beyond diet, Antioxidant Index can also reflect changes in exercise and lifestyle. “Carotenoids decrease when free radicals are excessively generated in the body, causing Antioxidant Index to drop,” she added. “For example, it may fall temporarily after unusually intense exercise.”

Google Gemini — available on a smartwatch for the first time — adds another layer to Antioxidant Index. “I once asked Gemini to suggest nearby restaurants with antioxidant-rich foods, and it gave me helpful options,” Park recalled. “Combining Antioxidant Index with personalized AI could further expand tailored healthcare.”

A Health Interpreter on the Finger

Park described Antioxidant Index as an interpreter that translates daily meals and lifestyle rhythms through a small light on the finger. “We often don’t realize how we eat or how much stress we’re under,” she said. “I hope Antioxidant Index can serve as a health interpreter that helps people better understand their well-being.”

“Disease prevention begins with healthy eating and lifestyle habits,” she continued. “With chronic illness rising rapidly among younger generations, Antioxidant Index can provide meaningful guidance in building healthier routines.”

Park added that Antioxidant Index is just one part of the bigger picture. “The Galaxy Watch series and Samsung Health offer valuable features like Sleep Score and Energy Score,” said Park. “By integrating these functions, we aim to deliver more comprehensive insights and a wider range of health information to users.”

As living to 100 becomes increasingly common, the focus is shifting from lifespan to healthy aging. The Galaxy Watch series is poised to open the next chapter in personalized health management.

Antioxidants play a key role in this process, helping neutralize free radicals and protect the body from oxidative stress. The Galaxy Watch8 series debuts Antioxidant Index — the first smartwatch feature to measure the body’s antioxidant status and support more effective health monitoring.

Samsung Newsroom spoke with Hyojee Joung — President of the Korean Nutrition Society and professor at Seoul National University (SNU), who participated in developing and validating the new feature — about this breakthrough and the importance of antioxidant care.

Why Antioxidant Care Matters

“Why do I feel tired so easily?”

Free radicals are natural byproducts of energy production in the body, but unhealthy habits can cause them to build up. “Tobacco use, alcohol consumption, poor diet, UV exposure and stress drive overproduction — triggering oxidative stress and accelerating aging,” said Joung.

Persistent exhaustion may signal excess free radicals in the body. “They can weaken immunity, cause fatigue and speed up visible signs of aging such as wrinkles or pigmentation,” Joung explained. “As oxidative stress accumulates, the risk of chronic diseases such as type 2 diabetes and certain cancers increases — making antioxidant management essential.”

▲ Excessive free radicals from an unhealthy lifestyle can raise the risk of chronic disease.

“Antioxidant capacity isn’t a matter of youth or fitness — it requires consistent care throughout life,” Joung emphasized, noting that daily fruit and vegetable intake is the easiest and most effective place to start.

Fruits and vegetables are rich in antioxidants such as carotenoids and vitamins C and E. Because the body’s natural production of antioxidant enzymes declines with age, sufficient dietary antioxidant intake provides the foundation for sustainable health.

However, for most people, it’s not easy to objectively assess whether their everyday diet is truly balanced. The Galaxy Watch8 series’ Antioxidant Index was developed to address this challenge.

Tracking Antioxidant Levels With Galaxy Watch8 Series

“Is my diet healthy enough?”

For anyone wondering how healthy their diet is, Samsung Health now offers a quick answer. Using rear sensors, the Galaxy Watch8 series measures an Antioxidant Index — based on carotenoid levels in the skin — to assess fruit and vegetable intake within seconds.

“Carotenoids are the red, yellow and green pigments in fruits and vegetables,” said Joung. “Because the human body cannot produce them, carotenoid levels reflect dietary intake.”

The Galaxy Watch8 series uses a reflection spectroscopy sensor. When light of a specific wavelength shines on the skin, carotenoids absorb some and reflect the rest. By analyzing the reflected light, the device estimates carotenoid levels.

Previously, measuring antioxidant levels required blood samples and complex laboratory procedures. Now, users can simply place a thumb on the back sensor for five seconds to see instant results. Based on the World Health Organization’s (WHO) daily recommendation of 400 grams of fruits and vegetables, results appear as:

• Very low – Less than 50% of the recommended intake
• Low – 50% to less than 100% of the recommended intake
• Adequate – 100% or more of the recommended intake

▲ Joung measures her Antioxidant Index with Galaxy Watch8 Classic.

Joung explained that although Antioxidant Index does not represent the body’s full antioxidant capacity, it serves as a practical and meaningful indicator of daily antioxidant status by reflecting carotenoid intake from fruits and vegetables — major sources that help strengthen the body’s antioxidant system.

Antioxidant Index: A Reliable and Validated Health Indicator

“How should I respond to my Antioxidant Index reading?”

The Galaxy Watch8 series is the first smartwatch to measure antioxidant levels — a breakthrough built on years of research. Samsung began collaborating with Joung and her team in 2018 to explore how this capability could be applied to wearables.

A dietary intervention study conducted by the Graduate School of Public Health at SNU confirmed that skin carotenoid levels reliably indicate fruit and vegetable intake. “Over six weeks, we provided meals with varying carotenoid content to 80 participants and observed their skin carotenoid levels increased within one to two weeks,” Joung said.

▲ Results from a dietary intervention study with 80 participants at SNU

When users measure their Antioxidant Index, the Samsung Health app provides feedback such as “Have one more tomato today” or “Try 50 grams of pumpkin.” These recommendations are based on proposals from Joung’s team. “It’s important to give dietary guidance in language users can easily understand,” she explained. “We created the foundational data that trained an algorithm to adapt suggestions to individual preferences.”

The research team plans to keep refining the feature to deliver more accurate insights and support more effective antioxidant management.

Tips for Using Antioxidant Index

Joung shared four tips for making the most of the Galaxy Watch8 series’ Antioxidant Index.

① Consistency is key — don’t worry about daily fluctuations.

② Measure at the same time, with the same finger.

③ Check results alongside other Samsung Health indicators.

④ Eat a variety of fruits and vegetables.

Small Steps, Big Changes

“Whenever I meet someone, I have them try Antioxidant Index. It’s fun to see their surprise at how quickly the results appear,” said Joung, an active Galaxy Watch8 Classic user. “Being able to check instantly is a huge advantage.”

“Many people try to manage antioxidants for disease prevention and healthy aging, but there hasn’t been a clear way to track progress,” she continued. “Antioxidant Index not only shows whether fruit and vegetable intake is sufficient but also raises awareness of the importance of antioxidants — and that alone is meaningful.”

“What matters is consistency, not perfection. Even small steps, like adding one serving of fruits or vegetables to your meal, can create meaningful change over time,” Joung emphasized. “I’m truly happy to see such an innovative feature come to life before my retirement.”

Antioxidant Index delivers results in just five seconds — a simple step toward better health. In the second part of this series, Samsung Newsroom will hear from one of the Galaxy Watch8 series’ developers who helped make this groundbreaking feature possible.

The Galaxy Watch8 series’ Running Coach feature offers personalized training for every skill level, helping runners — especially beginners and those who prefer to train solo — find joy in their progress.

After two years of running without a coach, Korean fitness influencer Narae Kim (@healthy_naraekim) felt her progress had plateaued. With Running Coach, she set out to push past that barrier. Samsung Newsroom followed her journey to see how it went.

Getting Started With Running Coach

Running without a goal can only take someone so far. For those unsure where to begin, the Galaxy Watch8 series offers an easy starting point. By simply slipping it on and heading outside, runners can use Running Coach in Samsung Health to set personalized goals.

The first step is the running level test. Before training begins, Running Coach evaluates a runner’s ability, assigns one of 10 levels and recommends a tailored program lasting three to five weeks.

▲ Running Coach evaluates each runner’s current ability before starting a program.

The method is simple — enter previous running experience into the Galaxy Watch8 series, then run as far as possible in 12 minutes. Beginners can start with walking or light jogging, gradually picking up the pace as guided by the watch. For the most accurate results, complete the test on a flat course and avoid overexertion the day before.

For her running level test, Kim ran at a steady pace for 12 minutes and entered her rating of perceived exertion (RPE).¹ The result placed her at level 6 — for runners aiming to complete a half marathon, with the specific goal of finishing 15 kilometers in under 1 hour, 42 minutes and 43 seconds. To reach that target, Running Coach created a five-week plan with 19 customized sessions.

Running Coach breaks down goals into 10 levels, guiding beginners toward a 5K and experienced runners toward a full marathon with step-by-step progression.

▲ Running Coach offers customized training plans for every level from beginners to marathoners.

Customized Programs To Match Any Level

One of the biggest questions in training is, “How far and how fast should I run today?” Running Coach provides a clear answer.

In the first week of her program, Kim opened Running Coach during an early morning visit to Hangang Park in Seoul. The day’s session was already laid out — no guesswork required.

Running Coach offers 15 to 19 customized sessions at each level. The plans call for three to four runs per week with recovery built in, making it easier to maintain a steady routine. After completing over 70% of a program, runners can test into the next level or retake the level test to update their training.

As a level 6 runner, Kim’s first session was a light 50-minute jog — manageable for her and a pleasant way to enjoy a crisp autumn morning.

▲ Sessions on Running Coach’s level 6 program

Running Coach in Samsung Health offers 160 programs, helping runners train systematically by level and goal. Instead of simply increasing intensity, the feature gradually adjusts difficulty to reduce injury risk and encourage lasting habits.

Beginners can build endurance with walking and low-intensity jogging, while skilled runners improve through sessions that incorporate high-intensity intervals, long slow distance² runs and fartlek training.³ Each level’s program is designed to steadily build ability, track progress and deliver a sense of accomplishment.

Coaching in Real Time

Consistency of pace is one of the most important aspects of running, but keeping breathing and speed steady can be difficult. When Kim’s breathing faltered during one session, her Galaxy Watch8 gave real-time audio feedback such as “Slow down” and “Keep it up!” — like having a personal coach at her side.

Running Coach is more than an app that tracks distance and time. Powered by the Galaxy Watch8 series’ advanced sensors, the feature delivers real-time data in an intuitive way — helping runners understand their pace and fitness level as they train.

▲ Running Coach provides real-time feedback, helping runners adjust heart rate and pace.

During runs, the watch displays key metrics such as split pace, heart rate and left-right balance to help runners stay in rhythm and build proper habits. After each session, a detailed report is generated with the runner’s self-entered RPE to show how well the run matched their fitness level.

▲ Runners can view post-run metrics including maximum oxygen uptake and heart rate.

Most importantly, Running Coach provides scored feedback that makes progress easy to see at a glance. Beyond simple numbers, the feature creates a sense of growth and achievement through structured training — a strength that sets it apart.

Add Up Scores To Build a Routine

Running consistently requires not only stamina but also routine. Beyond Running Coach, the Galaxy Watch8 series offers features that help build lasting habits.

Each morning, Kim checks her Energy Score and Sleep Score in Samsung Health to choose a running session that matches her condition. Energy Score combines sleep, activity and heart rate data to measure physical and mental wellness on a scale of 0 to 100. The feature also offers daily recovery tips to balance exercise and rest.

As a professional who often works overtime, she has found this feature especially helpful for maintaining her program without overexertion.

▲ Energy Score and Sleep Score in Samsung Health

Google Gemini — available on a smartwatch for the first time with the Galaxy Watch8 series — takes the running experience even further. From her wrist, Kim asked, “Show me nearby flat running routes.” With Gemini’s help, she discovered new courses to explore.

Even indoors on the treadmill, she could simply say, “Convert my pace in minutes per kilometer to treadmill speed in kilometers per hour.” Gemini instantly delivers the result, making the feature just as useful for indoor training.

A Partner for the Long Run

After completing her five-week plan, Kim retook the running level test — and advanced to the next tier. The personalized training programs in Galaxy Watch8 series’ Running Coach had clearly elevated her performance.

“My goal is to complete a half marathon. Before using Running Coach, I often felt uncertain about pacing and adjusting intensity. But with its tailored programs and data-driven feedback, the quality and efficiency of my runs have clearly improved,” said Kim, reflecting on her experience. “What impressed me most was how it guides you step by step from the basics, almost like a textbook. I’d highly recommend it to beginner runners.”

“Running isn’t about heading out every single day — it’s more important to alternate training with recovery,” she added. For beginners, she recommended what she calls “leapfrog running,” an every-other-day approach. “The biggest motivation in running comes from seeing your own progress and achievements. With Running Coach, you can stay motivated to the very end — even when running solo.”

Consistency is the hardest part of running. But now, the Galaxy Watch8 series is a dependable partner on the wrist — one that tracks a runner’s rhythm and stays by their side. For anyone hoping to build the habit and sharpen their skills, why not start with the Galaxy Watch8 series’ Running Coach?

¹ Rating of perceived exertion is a scale used to subjectively measure the intensity of physical activity.
² Long slow distance is a training method builds endurance and cardiovascular strength by running long distances at a slow pace.
³ Fartlek, Swedish for “speed play,” is a flexible training method that alternates faster running with slower jogging without fixed intervals.

Leading the Charge in Sleep Health

One of Samsung’s newest innovations in personalized health experiences is the Galaxy Watch8 series, launched in July 2025 with advanced features to improve sleep tracking and coaching.

The Bedtime Guidance feature offers personalized recommendations based on the two-process model of sleep regulation — a scientific framework that describes the interaction between homeostatic sleep drive and circadian rhythms. By applying this model, Bedtime Guidance¹ helps users establish healthier routines that support consistent, restorative sleep.

The Galaxy Watch8 series also includes a Sleep Apnea² feature for users 22 and older who have not been diagnosed with the condition. The tool can detect signs of moderate to severe obstructive sleep apnea (OSA) after just two nights of monitoring. Because OSA is a common, chronic condition that often goes undiagnosed, early detection can encourage users to seek medical attention and reduce long-term health risks.

Furthermore, the Galaxy Watch8 series incorporates the Vascular Load³ feature to track stress levels in the vascular system during sleep. This stress typically decreases at night, but excessive fluctuations can harm cardiovascular health. By providing insights into sleep, stress and activity, Vascular Load helps users better understand their wellness and encourages small, consistent lifestyle changes for long-term cardiovascular health.

Building Wellness Through Everyday Insights

The Galaxy Watch8 series offers expanded health and fitness capabilities. Antioxidant Index⁴ — introduced for the first time on a smartwatch — measures carotenoid levels in the skin, while Running Coach⁵ creates customized three- to five-week training programs. Stress management tools include High Stress Alert, guided breathing exercises and Energy Score.

These wellness tools demonstrate Samsung’s commitment to turning fragmented health data into meaningful, personalized insights that support simple, daily habits. By combining advanced sensors, AI-driven insights and a connected health ecosystem, Samsung is setting new standards for how wearables can improve health — one night’s sleep at a time.

Building upon the foundation of the Galaxy Watch Ultra’s cushion design, this series boasts the thinnest, most comfortable Galaxy Watch ever² for continuous health tracking. The Galaxy Watch8 series suits diverse lifestyles and provides advanced capabilities, setting a new standard for style and personalized health experiences.

Redesigned Inside and Out for Ultimate Wellness

By reimagining both form and function, the Galaxy Watch8 series delivers unmatched comfort alongside industry-leading performance, making it the ultimate companion for everyday wellness. The distinctive cushion design, which debuted with Galaxy Watch Ultra, now defines the entire Galaxy Watch lineup.

Combined with the Dynamic Lug system, this design moves naturally with the wrist, providing greater comfort and improved stability² for a better fit and enhanced health-tracking accuracy.

Galaxy Watch8’s sleek profile is complemented by its exceptional performance. Even when you are outdoors under bright sunlight, the display is 50% brighter² with a peak brightness of 3,000nits for easy visibility, and the enhanced battery² ensures the watch can keep up with an active lifestyle.

On top of that, the Galaxy Watch8 series comes with new unique health features on the Samsung Health app³ that help you build healthier habits through instant, motivational insights – from sleep to nutrition and workout.

With Mindfulness Tracker, you can record your mood and receive guidance on breathing exercises to relieve your stress – all at once on your wrist.

Plus, the AI-powered Energy Score⁸ gives you a snapshot of your energy level, combining physical and mental energy metrics so you can have a healthier day, every day.

Go hands-free using natural voice commands to get things done on the go with your Galaxy Watch apps like Samsung Health, Calendar, Reminder and Clock. For example, you can ask Gemini to find a nearby cafe and text a friend to meet you there, all in one go. Or, if you’re ready to start your workout and you have a goal in mind, simply say, “Start a 30-minute run.” The watch seamlessly initiates the workout in Samsung Health.
