Make Room for Nutrition
in the Preventive Care Visit.
Lifestyle medicine conversations are easier when there is something concrete on the table. 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 alongside your usual visit, so your workflow stays as it is, and it gives you a talking point, a reason to schedule a follow-up and an extra, openly disclosed revenue stream for the practice.
- A fingertip scan returns a personal, trackable wellness score in about 15 seconds
- A concrete reference point for the nutrition and lifestyle advice you already offer
- Works at health fairs, employer wellness days and community talks as well as in the office
No obligation. One short call is enough to judge whether Prysm iO belongs in your practice.
Patients Put Money Into Their Health. Few Can Track the Result.
Many patients arrive having bought supplements, changed their meals and tried new routines on their own, with no way of telling what is making a difference. Prysm iO offers a quick, non-invasive scan that turns skin carotenoid information into a score patients can read and follow from one appointment to the next.
1 scan
A baseline reading for each patient, so food and supplement choices can be revisited at the next visit
15 sec
From fingertip to personal wellness score, faster than it takes to scroll back through the chart
0 needles
No blood draw, no lab order and no prep, so it fits into the time you already have with the patient
Is the Diet Delivering What Patients Think It Is?
Ask a roomful 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 served, so even a careful diet can fall short of what people assume.
A cupboard full of bottles, and no feedback
Many patients take several products every day on trust. Asking what they take and why is already part of a good history, and a reading gives that question somewhere to go.
Their own number, not a population figure
Each patient gets a personal carotenoid-based score, which makes the discussion about them rather than about averages. It slots naturally into the exam-room conversation.
A guarantee behind the range
The Pharmanex Certified range is designed for people whose scores have room to improve. If a score has not improved after 90-100 days on a certified, Prysm-eligible product, Nu Skin refunds the purchase, subject to Nu Skin's Terms and Conditions.
Replace guesswork with a number you and your patient can follow together, backed by a range designed to help move it.
The Nutrients Behind the Score
Patients often ask their physician what they should be taking, and a thoughtful answer builds trust. The Pharmanex range is built around carotenoids and other everyday nutrients, in formulas designed for high bioavailability, so patients can follow their own score as they make nutrition choices.
Lutein and other carotenoids
Products across the range contain lutein in a highly bioavailable form, together with other carotenoids. Carotenoids are the pigments the scanner reads in the skin.
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 practical option for patients whose meals leave gaps.
Documented Before It Reaches Patients
Every Pharmanex formula goes through the company's 6S Quality Process: selection, sourcing, structure, standardization, safety and substantiation. Substantiation means the company records the support behind what it says about a product.
Scan First, Then Compare
A patient who already takes another product can be scanned first to record a baseline. If they later switch to a Prysm-certified alternative, repeat scans over the following weeks show how their own score moves. The scan reads skin carotenoid levels, and the trend is what matters to the patient.
100 Million Healthy Households
Some patients will want a Prysm iO of their own, to keep scanning at home and to include the family in a bit of friendly competition for the top score. Nu Skin has described an ambition of 100 million healthy households, each with a device and better nutrition habits. If you offer a device to patients, be upfront about your financial interest.
If another physician or healthcare provider has recommended a supplement, it should only be changed with that provider's agreement. The score is a wellness reading that sits alongside, and never stands in for, a physician's own evaluation and care.

You Already Counsel on Lifestyle.
Now Give Nutrition a Number.
Prysm iO is not a medical device and it does not change how you practice. It is a wellness tool that runs next to your existing care: a scan of about 15 seconds that gives patients a trackable view of their nutritional wellness, to complement your examination and counseling.
For patients it is one more reference point in the conversation about their health habits. For your practice it is a way to deepen engagement, encourage follow-up and add a transparent revenue stream, without adding to your workload.
Patients Who Stay Engaged
A wellness score gives patients something to care about beyond the reason they booked. It creates a visible thread from visit to visit: a number to follow, discuss and work on together.
An Easy Reason to Return
People who can see their own numbers move are more likely to keep going with a plan. A repeat scan is a gentle, low-pressure prompt to book the next appointment.
A Disclosed Revenue Stream
Offer scans as a stand-alone service, add them to programs you already run, or build a wellness membership around them. The income comes from the device rather than from extra hours at the bedside, and it should always be disclosed to patients.
A non-invasive scan, from fingertip to finished score
Hyperspectral measurements taken in each reading
One clear, trackable number that patients understand at a glance
“They trust you with their health. Give them a number that shows nutrition is part of the picture.”
Turning Light Into a Nutrition Score
Prysm iO shines light on a fingertip and returns a personal nutritional wellness score in about 15 seconds. There is no blood draw, no lab visit and no paperwork.
The result is easy to read and easy to track, so patients can make sense of it and act on it alongside the care you already provide.
Every reading uses the same spot, a fingertip on the same hand each time, so results stay comparable from one scan to the next. That consistency is what makes a trend worth following, instead of a single number that shifts with how the device was 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 after that it slots 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, and it does not replace a physician's own evaluation.
Fifteen Seconds, No Needles
Quick and non-invasive, so it works in an exam room, at the front desk or on a health-fair table. No preparation, no blood draw and no lab order.
Hyperspectral Measurement
Prysm iO uses hyperspectral absorption to take more than 700,000 individual light measurements per scan, reading skin carotenoid levels from a fingertip resting on the sensor.
A Score Patients Can Read
An AI algorithm that references Raman spectroscopy research turns the measurements into one Prysm Score between 100 and 1000, a plain-language result patients receive within seconds.
Tracking Between Visits
A companion app lets patients follow their score between appointments, which reinforces the habits you recommend and gives your staff a natural reason to check in.
Two Decades of Development
Prysm iO builds on more than 20 years of Pharmanex (a division of Nu Skin) R&D, including 110 studies, 180 white papers and 18 global patents. It is established technology rather than a passing gadget.
For Physicians Who Care About Prevention
Prysm iO suits physicians who value evidence and results and want to show patients a fuller picture of their wellness. It is an especially good match for MDs and DOs who are comfortable introducing new technology and who want longer, more engaged relationships with their patients.
Independent Practices
MDs and DOs who own their practice and want a simple, technology-led service and another revenue stream without extra headcount or longer visits.
Primary Care and Family Medicine
Family medicine, internal medicine and other primary care physicians who bring up nutrition and prevention at most visits and want a number to anchor the discussion.
Lifestyle and Preventive Medicine
Practices whose patients are already invested in staying well and often ask what more they can do at home. Specialists with a prevention-minded patient base are welcome too.
Community-Minded Physicians
Physicians who volunteer at health fairs, school visits, employer wellness days or community education and want something hands-on that draws people in.
Follow-Up Focused Practices
Offices looking for a natural, low-key reason to bring patients back, since a repeat scan gives each visit something visible to look forward to.
Early Adopters
Physicians who like to be first in their area with credible, research-backed technology, and who want their practice to stand out. Nurse practitioners and physician assistants in your practice are welcome to take part as well.
Sound like your practice?
If one of these sounds like your practice, the next step is a brief, no-obligation call to see whether Prysm iO fits.
“Light, a fingertip and fifteen seconds: a nutrition conversation your patients can see.”
Prysm iO grows out of two decades of Pharmanex research, part of Nu Skin Enterprises, and received recognition in 2025 from the Titan Awards, Globee Business Awards, Good Design Awards and Big Innovation Awards. It is externally recognized technology rather than a supplement sales pitch.
Yale Researchers Reviewed the Method Behind the Scan
The skin-scanning method that Prysm iO builds on was reviewed by researchers at the Yale School of Public Health, whose 2013 paper called skin carotenoid status “an attractive biomarker for use in human studies.”
