Put a Nutrition Number
Beside Every Plan of Care.
Patients spend weeks working hard on their recovery, and many want to know what else they should be doing at home. Prysm iO is a wellness tool that provides information about skin carotenoid levels in about 15 seconds. It is not a medical device and is not intended to diagnose, treat, cure or prevent any disease. It runs separately from your evaluations and treatment sessions, so your plan of care stays exactly as it is, and it gives your clinic an easy conversation-starter, a friendly reason to check in again, and an additional, openly disclosed revenue stream.
- Each scan takes about 15 seconds and returns a personal, repeatable wellness score
- A concrete talking point for the healthy-habits advice you already share between sessions
- A natural draw at community races, senior center talks, school sports nights and employer wellness days
No obligation. One short conversation shows whether Prysm iO belongs in your clinic.
Patients Put In the Effort. Few Can See the Nutrition Side.
People in a plan of care are often changing what they eat, buying supplements and trying new routines at home, with nothing to show how those choices are going. Prysm iO offers a quick, non-invasive scan that turns skin carotenoid levels into a wellness score patients can understand and revisit from one appointment to the next.

Global dietary supplements market, yet few ways for people to see how their own choices are going
Is Their Diet Delivering What They Think It Is?
Ask a room of patients and most will say they eat fairly well, but good intentions are not a measurement. Fresh produce starts losing nutrients soon after harvest, long before it is on the plate, so even a careful diet may fall short of what people expect.
The pill organizer is full. Is it doing anything?
Many patients take several products a day on trust. Asking how those choices are going fits naturally into the lifestyle conversation you already have around their plan of care.
Their own number, not an average
Each scan returns a personal carotenoid-based score instead of a population average. It slots easily into a treatment-room chat alongside the rest of their program.
A guarantee behind the range
The Pharmanex Certified range is designed for scores with room to improve, and Nu Skin backs it: if a score has not improved after 90-100 days on a certified, Prysm-eligible product, the purchase is refunded, subject to Nu Skin's Terms and Conditions.
Replace guesswork with a number you and your patient can watch together, backed by a range designed to move it.
The Nutrients Behind the Score
Patients often ask their physical therapist what they should be taking, and a considered, honest answer builds trust. The Pharmanex range centers on carotenoids and other everyday nutrients, so patients can follow their own score alongside the nutrition choices they make.
Lutein and other carotenoids
Products across the range contain lutein alongside other carotenoids. Carotenoids are the plant pigments whose levels the scanner reads at the fingertip.
Omega-3: EPA and DHA
Marine Omega provides EPA and DHA omega-3 fatty acids to support heart health.*
Vitamins and minerals
LifePak provides a broad range of vitamins and minerals to support overall nutritional wellness and immune health.*
A fruit-and-vegetable beverage
JVi is a source of vitamin C and also contains carotenoids, a convenient option for patients whose busy days leave gaps in their meals.
Documented Before It Is Sold
Each Pharmanex formula goes through the company's 6S Quality Process: selection, sourcing, structure, standardization, safety and substantiation. Substantiation means the company keeps documentation behind its product claims. Patients can then scan and watch their own score over time.
Scan First, Then Compare
If a patient already takes another product, scan them first to note where they start. Should they later switch to a Prysm-certified option, repeat scans over the following weeks will show how their own score moves. The scanner reads skin carotenoid levels, so the number is theirs to follow over time.
100 Million Healthy Households
Some patients will want their own Prysm iO to scan at home and to involve family members, with a little friendly rivalry over who scores highest. Nu Skin has described a goal of 100 million healthy households, each with a device and better nutrition habits. If you offer patients a device, be upfront about your financial interest.
Supplements recommended by a patient's doctor or another healthcare provider should only be changed with that provider's agreement. The score is a wellness reading that complements, and never replaces, medical advice or physical therapy care.
*These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Dietary supplements do not replace a varied, balanced diet. Prysm iO is a wellness insight tool and is not a medical device. Please read each product's label for its exact ingredients and amounts.
You Already Coach Patients on Movement.
Add a Number for Nutrition.
Prysm iO is not a treatment and it does not change how you evaluate or treat. It is a wellness tool that sits alongside your existing sessions: a 15-second scan that gives patients a trackable look at one nutrition-related marker, to go with the exercise, education and lifestyle advice you already provide.
For patients it is one more talking point about their everyday habits. For your clinic it is a way to deepen engagement, stay in touch after discharge and add a transparent revenue stream, with no change to your plans of care.
Patients Who Stay Engaged
A wellness score gives patients something to care about beyond the injury or the exercise sheet. It creates a visible thread from one session to the next: a number to talk about and work on together.
An Easy Check-In
A repeat scan gives your front desk a friendly, low-pressure reason to get in touch after discharge, or to mention at a wellness or maintenance visit.
An Added, Disclosed Revenue Line
Offer scans as a stand-alone cash-pay wellness service, pair them with a fitness or wellness program, or build a membership around them. The income comes from a device rather than extra treatment hours, and it should always be disclosed to patients up front.
A non-invasive scan, from fingertip to finished result
Hyperspectral light measurements taken in each reading
One simple, repeatable number that patients understand at a glance
“They trust you to keep them moving. Give them one more thing they can see and follow between visits.”
Turning Light Into a Nutrition Score
Prysm iO uses light-based scanning to return a personal nutritional wellness score in about 15 seconds, with no blood draw, no lab visit and no paperwork beyond a few taps in the app.
The result is simple and repeatable, so patients can understand it and use it alongside the care you already provide.
Each reading is taken at the same spot, a fingertip on the same hand every time, which keeps scans comparable. That is what makes a trend meaningful instead of a single number that changes with how the device happened to be held. The scanner pairs with the Prysm iO app on an iOS or Android phone or tablet. The app takes a little time to learn, and then it fits easily into a patient visit.
Prysm iO is a wellness tool and is not a medical device. It is not intended to diagnose, treat, cure, or prevent any disease or medical condition, and it does not replace medical advice or physical therapy care.
Fifteen Seconds, No Needles
Quick and non-invasive, and simple to run in a treatment room, at the front desk or at a community-event table. No preparation, no blood draw and no lab order.
Hyperspectral Measurement
Prysm iO uses hyperspectral absorption to capture more than 700,000 individual light measurements per scan, reading skin carotenoid levels from a simple fingertip placement.
A Score Patients Can Read
The measurements are converted into a single Prysm Score from 100 to 1000 by an AI algorithm that references Raman spectroscopy, so patients get an easy-to-read result within seconds.
Tracking Between Visits
A companion app lets patients follow their score between appointments, which supports the healthy habits you talk about and gives your team a natural reason to check in.
Two Decades of Development
Prysm iO builds on more than 20 years of research and development at Pharmanex, a division of Nu Skin, including 18 global patents.
For Physical Therapists Who Coach the Whole Patient
Prysm iO suits physical therapists who care about their patients' everyday habits as well as their range of motion, and who want to offer a fuller picture of wellness. It is a particularly good match for PTs who are comfortable introducing new technology and who want longer, more engaged relationships with the people they treat.
Independent Clinic Owners
Physical therapists who own their clinic and want a simple, technology-led service and another revenue stream without hiring staff or lengthening treatment sessions.
Outpatient Orthopedic and Sports Clinics
Therapists who spend weeks with active patients, talk about fueling and recovery habits, and would like a simple number to anchor that conversation.
Pelvic Health and Geriatric Programs
Programs where patients work closely with one therapist over time, value a personal approach to healthy living and often ask what else they should be doing at home.
Community-Minded Therapists
PTs who show up at charity runs, senior center talks, school visits or employer wellness days and want something hands-on that gets people to stop and chat.
Clinics Focused on Staying in Touch
Teams that want a friendly reason to reach out to former patients and wellness clients. A repeat scan gives each check-in something concrete to talk about.
Early Adopters
Therapists who like to try new technology early and want a way to set their clinic apart from others in the same town.
Sound like your clinic?
If any of these describe your clinic, the next step is a brief, no-obligation conversation to see whether Prysm iO is a match.
Nature-inspired technology from the Pharmanex team that has spent decades working with carotenoids.
Prysm iO grows out of two decades of Pharmanex work, part of Nu Skin Enterprises, and received design and technology awards in 2025 from the Titan Awards, Globee Business Awards, Good Design Award and Big Innovation Awards. It is a technology product first, not simply a supplement pitch.
Academic Researchers Have Studied Skin Carotenoid Scanning
The skin-scanning approach that Prysm iO builds on has been written about in the academic literature, including a 2013 review from researchers at the Yale School of Public Health on skin carotenoids as a marker for use in human nutrition studies.
Nu Skin also reports ongoing research on Prysm iO itself, including early pilot work that has not completed peer review. Nothing on this site claims that Prysm iO diagnoses, treats, cures or prevents any condition, or that a score predicts a health outcome.

Every scan is a friendly first introduction to your clinic.
Attract
A sleek scanner with a glowing light ring draws people to your table at fun runs, health fairs and community events much better than a stack of flyers.
Offer
Invite passers-by to try a free scan that takes about 15 seconds. It is quick, non-invasive and gives each person something to take away for a minute of their time.
Talk
The score starts the conversation, an easy and relaxed way to chat about healthy habits, what your clinic does and how physical therapy can help people stay active.
Follow Up
With permission, note their contact details alongside the scan and follow up with someone who already has a personal reason to get to know your clinic.
