Give Every Client a
Nutrition Score to Follow.
Prysm iO is a non-invasive wellness insight tool that estimates skin carotenoid levels with light, to start a conversation about nutrition and lifestyle. It is not a medical device and does not diagnose, treat or screen for any condition. A scan takes about 15 seconds and slots into the way you already work - no new protocol, no extra equipment setup beyond a phone or tablet - giving your practice a fresh conversation-starter, a reason for clients to keep coming back, and an additional service line.
- One 15-second scan gives each client a personal wellness score they can track over time
- A tangible reference point for the food and lifestyle guidance you already give
- A friendly way to draw people in at workshops, wellness days and community events
No obligation. A short conversation is all it takes to see whether Prysm iO belongs in your practice.
Clients Invest in Their Diet. Few Get Anything to Look Back On.
People who come to you for guidance on eating well are also stocking the cupboard with supplements, reshaping their meals and trying new routines - yet between sessions there is often nothing concrete to show how they are getting on. Prysm iO adds that missing piece: a quick, non-invasive scan that turns skin carotenoid levels into a single score your clients can understand and follow from one session to the next.

Is Their Plate Doing What They Believe It Is?
Ask a client whether they eat well and most will say yes - but good intentions are not a measurement. Fresh produce begins losing nutrients as soon as it is harvested, well before it reaches the table, so a diet that looks healthy can still leave a real gap.
They take a supplement. Then what?
Plenty of clients swallow a daily product on trust and never find out what, if anything, it is doing for them. Asking that question openly is a natural part of the whole-food, whole-person conversation you already lead.
A personal starting point
Each client gets a score of their own, based on their own skin carotenoid reading, rather than a population average. It drops easily into a consultation and sits comfortably beside the plan you have built with them.
Backed by a guarantee
Nu Skin offers a money-back guarantee on its Pharmanex Certified range: if a client's score has not improved after 90-100 days on a certified, Prysm-eligible product, the purchase is refundable, subject to Nu Skin's Terms and Conditions.
Swap assumption for a number that you and your client can follow together - and offer a supplement range that is formulated with that number in mind.
What Stands Behind the Number
Clients regularly ask their nutrition professional what, if anything, to add to their plan, and a considered answer builds trust. The Pharmanex range is built around carotenoids and other everyday nutrients in formulas designed for high bioavailability, so clients can follow their own score next to the food choices they are making.
Lutein and other carotenoids
Products across the range contain lutein in a highly bioavailable form, alongside other carotenoids. Carotenoids are the pigments the scanner reads in the skin.
Omega-3: EPA and DHA
Marine Omega is an omega-3 supplement supplying EPA and DHA, the fatty acids found in oily fish, to complement a varied, balanced diet.
Vitamins and minerals
LifePak is a multi-nutrient daily supplement providing a range of vitamins and minerals to complement a varied, balanced diet. Permitted product statements differ by country, so please read the label for your market.
A fruit-and-vegetable beverage
JVi is a source of vitamin C that also contains carotenoids - a practical option for clients whose meals tend to fall short on fruit and vegetables.
Tested Before It Is Sold
Pharmanex formulas go through the company's 6S Quality Process, which covers selection, sourcing, structure, standardization, safety and substantiation - the last of which means the company documents the support behind its product claims. Even so, the most persuasive evidence is personal: a client scans, follows their plan, and sees their own score move.
Establish a Baseline, Then Re-Scan
A client who already takes a different supplement can be scanned first, to record where they begin. If they later switch to a Prysm-certified alternative, re-scanning over the following weeks shows how their own score changes. Because the scan reads skin carotenoid levels, clients can watch their personal trend over time.
100 Million Healthy Households
Some clients will want a Prysm iO of their own at home, to keep scanning and to include family members, with a bit of friendly competition over who scores highest. Nu Skin has stated a goal of 100 million healthy households, each with a device and better nutrition habits, and your practice can be where that begins for a family.
A supplement advised by a client's physician or another healthcare provider should only be changed with that provider's agreement. The score is a wellness reading that complements, and never replaces, a consultation or professional advice.
These statements have not been evaluated by the Food and Drug Administration. These products are 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 Guide What They Eat.
Now Give Them Something to Measure It By.
Prysm iO does not replace your assessment, your plans or your judgment. It is a technology add-on that sits alongside your existing way of working: a 15-second scan that gives each client a personal, trackable reading of their skin carotenoid levels to go with the dietary and lifestyle guidance you already provide.
For clients it is one more reference point in the conversation about how their eating habits are going. For your practice it is a way to deepen engagement, encourage return visits and add a credible service line - without adding to your workload.
Clients Who Stay Involved
A personal score gives clients something to look forward to between sessions. It strings your appointments together with a visible thread - a number to track, discuss and work on side by side each time you meet.
Longer Client Relationships
People who can watch their own number move tend to keep going with a plan. A re-scan is an easy, low-pressure reason to book the next session and keep the relationship alive.
An Additional Service Line
Offer scans as a stand-alone service, fold them into existing programs, or build a membership around them. The income comes from a device you already own rather than from extra hours in your diary.
A non-invasive scan, from fingertip placement to finished reading
Hyperspectral measurements taken in each reading
One clear, trackable number that clients grasp straight away
“They already trust you with their food choices. Give them a number that turns that advice into something they can see.”
Making Nutrition Visible
Prysm iO uses light-based scanning to produce a personal nutritional wellness score in around 15 seconds. There is no blood draw, no lab booking and no complicated procedure.
The result is simple and trackable, so clients can make sense of it and use it alongside the guidance you already give them.
Every reading is taken at the same spot - a fingertip on the same hand each time - so scans stay comparable with one another. That repeatability is what gives a trend line meaning, as opposed to a one-off figure that could shift depending on how the device was held. The scanner connects to the Prysm iO app on an iOS or Android phone or tablet. Getting the app set up and finding your way around takes a little time, after which it slots neatly into a client session.
Prysm iO is a wellness insight tool and is not a medical device. It is not intended to diagnose, treat, cure, prevent, or mitigate any disease or medical condition, and it does not replace a consultation or professional advice appropriate to your field.
A Scan in 15 Seconds
Quick, non-invasive and easy to run almost anywhere - a consulting room, a reception desk, a video-call follow-up kit or a busy workshop table. No preparation, no blood draw and no lab visit.
Hyperspectral Measurement
With a fingertip resting on the sensor, Prysm iO uses hyperspectral absorption to gather more than 700,000 separate light measurements in each scan and estimate skin carotenoid levels.
One Score That Makes Sense
The measurements are converted into a single Prysm Score from 100 to 1000 by an AI algorithm that references Raman spectroscopy, so clients receive a clear, plain-language result within seconds.
Progress in an App
A companion app lets clients follow their score between sessions, which reinforces the habits you suggest and gives you a natural prompt for a check-in.
Decades of Research Behind It
Prysm iO draws on more than 20 years of Pharmanex (a division of Nu Skin) R&D, including 110 studies, 180 white papers and 18 global patents - serious technology, not a novelty gadget.
For Nutrition Professionals Who Want More Than Food Diaries
Prysm iO suits practices that value evidence and want to show clients a fuller picture of their wellness. It is an especially good match for nutritionists, nutritional therapists and health coaches who are comfortable introducing new technology and who want a more engaged, longer-standing client base.
Solo Nutrition Practitioners
Independent nutritionists and nutritional therapists who want a straightforward way to add a technology-led service and an extra income stream without taking on staff or lengthening sessions.
Multi-Disciplinary Clinics
Clinics where nutrition sits beside physiotherapy, naturopathy, fitness or mental wellbeing work, and a shared wellness score helps tie the different strands together.
Supplement-Savvy Practitioners
Practitioners who already talk through supplements and lifestyle with their clients and would like something measurable behind those conversations rather than general advice alone.
Community-Facing Coaches
Health and nutrition coaches who run workshops, corporate wellness sessions, gym partnerships or community talks, and want a device that draws people over as well as adding value in one-to-one work.
Online and Remote Practices
Practitioners who see clients by video and want a simple at-home check-in tool to keep follow-up sessions anchored to something concrete.
Early Adopters
Practitioners who like being first in their area with credible, research-informed technology, and who use it to set their practice apart from others nearby.

“Nature-inspired, research-driven innovation - from the same scientific pioneers behind organ-transplant medicine and the first oral contraceptive.”
Prysm iO builds on two decades of Pharmanex research, part of Nu Skin Enterprises, and picked up recognition in 2025 from the Titan Awards, Globee Business Awards, Good Design Award and Big Innovation Awards. It is technology that outside judges have noticed, not just a supplement pitch.
Yale Researchers Examined the Science Behind the Scan
The skin-scanning science that Prysm iO builds on was independently reviewed by the Yale School of Public Health. Their 2013 paper called skin carotenoid status “an attractive biomarker for use in human studies” and noted that repeat readings are highly reproducible.
