Turn “Your Nutrition Is Improving” Into
a Score Clients Can Watch Rise.
Food diaries, symptom questionnaires, and testing tell you a lot - but clients rarely see the proof that their changes are working. Prysm iO adds a 15-second, non-invasive fingertip scan that turns nutritional wellness into a score they can see, understand, and track between consultations - without changing a single thing about how you assess or advise.
- A 15-second scan turns nutritional wellness into a score clients can track
- Sits alongside food diaries, testing, and your existing protocols - however you already work
- A natural talking point at wellbeing fairs, corporate wellness days, and nutrition events
Nothing to sign today - just a conversation to work out whether Prysm iO makes sense for your practice.
You Track Their Intake. What About the Result?
A good nutrition plan is built on food diaries, symptom scores, and sometimes lab work - but between consultations clients are largely taking your word for it that the changes are working. Prysm iO gives them something to see: a 15-second, non-invasive scan that reads skin carotenoid levels, a recognised marker of fruit-and-vegetable intake and antioxidant status, as a score they can track as their nutrition and supplements evolve.

Is Their Diet Actually Closing the Gap?
Clients rarely arrive doubting their own diet - working out where it actually falls short is usually the job of the first consultation. Nutrient content falls from the moment produce is picked, well before it reaches a plate, which is precisely the kind of gap a trained eye is needed to catch.
So they take a supplement. Then what?
Many clients already take something daily on faith - a bottle, a routine, a hope it's doing something - with no real feedback on whether it is working or even needed. That is a question worth answering with data, not reassurance.
A measured starting point, not a guess
A 15-second scan gives a client their own carotenoid score, a genuine personal starting point rather than a generic recommendation, and something you can track precisely alongside the rest of their plan.
Evidence, not just a claim
The Pharmanex Certified range exists to move a score that has room to climb, and Nu Skin backs that claim rather than just making it: no improvement within 90-100 days on a certified, Prysm-eligible product means a full refund, subject to Nu Skin's Terms and Conditions.
Turn a first-consultation hunch into a measured baseline, and recommend a range built to move it.
The Products Behind the Number
Nutritionists know that a supplement is only worth recommending if it is absorbed. The Pharmanex range is built around carotenoids and other core nutrients, and its formulas are designed to be highly bioavailable, which is exactly what a skin carotenoid score is well placed to demonstrate over time. Food comes first, and these products are there to support it.
Lutein and other carotenoids
Lutein is included in products in the range in a highly bioavailable form, together with other carotenoids. They are the pigments the scan reads in the skin, so a client's score gives you a direct view of how their intake is landing.
Omega-3: EPA and DHA
Marine Omega supplies EPA and DHA, which support normal heart function as part of a varied diet.
Vitamins and minerals
LifePak formulas provide a broad base of vitamins and minerals formulated to support the immune system, energy metabolism and everyday wellness.
A fruit-and-vegetable top-up
JVi is a fruit-and-vegetable beverage that is a source of vitamin C and contains carotenoids, useful for clients whose intake of produce falls short.
Substantiated Before It Reaches the Shelf
Every Pharmanex formula goes through Pharmanex's 6S Quality Process: selection, sourcing, structure, standardisation, safety and substantiation. The last of those means product claims rest on documented preclinical and clinical studies. The most persuasive evidence of all, though, is the client's own: they scan, take the products, and watch their own score move.
Baseline Their Current Protocol, Then Re-Scan
You can scan a client on any other product to set a baseline, then, if they decide to switch to a Prysm-certified alternative, re-scan them over the following weeks and let the score show what is happening. Because the scan reads carotenoids in skin tissue, a rising score is an objective sign that what they are taking is being absorbed, rather than assumed.
100 Million Healthy Households
Many clients will want a device of their own to re-scan at home and to scan family members too, which turns one person's plan into a household habit. Nu Skin's stated aim is 100 million healthy households, each with a Prysm device and a shared interest in nutrition and supplementation, and you can be the one who brings it into their kitchen.
If a client's GP, dietitian or another clinician has advised a supplement, it should only be changed with that professional's agreement. The score is a wellness reading, not a reason to alter anything medically advised.
Food supplements are not a substitute for a varied and balanced diet. These products are not medicines, and Prysm iO is a wellness insight tool that does not diagnose, treat, cure or prevent any condition or replace nutritional therapy assessment or medical advice. Please check each product's label for its exact ingredients and amounts.
Same Food-First Approach.
One Objective Number.
Prysm iO isn't a new protocol to learn or a different way of working - it sits quietly alongside whatever combination of nutritional, functional, or lifestyle approaches you already use. In 15 seconds, it turns nutritional wellness into an objective score that supports your recommendations rather than competing with them.
For clients, it's tangible feedback that the effort they are putting in is registering. For your practice, it's a way to strengthen follow-through, give people a reason to return, and add a credible income stream - without adding a minute to your consultation time.
A Reason to Come Back
A wellness score gives clients something to check in on beyond how they feel that week - a running thread they can watch move, consultation after consultation.
Loyalty Built on Evidence
Seeing their own progress in black and white keeps clients bought into the plan. Booking a re-scan is an easy, unforced way to schedule the next follow-up.
Revenue That Doesn't Cost You Time
Offer scans as a one-off add-on, fold them into an existing package, or use them to launch a wellness membership. It is income built on a device you already own, not extra hours in the consultation room.
From fingertip placement to a finished reading, start to finish
Individual light measurements captured in a single scan
One clear number clients grasp without any explanation
“Nutrition already changes how people live, not just their diet. Prysm iO simply gives that change a number.”
How a Light Reading Becomes a Score
Prysm iO uses optical scanning technology to turn nutritional wellness into a personalised score in around 15 seconds - no blood draw, no lab appointment, and nothing complicated for the client to sit through.
What comes out the other end is a single, trackable result - something your clients can understand at a glance and you can build into the conversation you are already having with them.
Every reading is taken from the same spot - a fingertip placement on the same hand each time - which keeps results consistent scan to scan. That consistency is what makes the trend line trustworthy, rather than a single number that could shift depending on how the device was held. The device pairs with the Prysm iO app on an iOS or Android phone or tablet. You will need to install the app and spend a little time getting to know it, but once you have, it slots straight into a consultation.
Prysm iO is a wellness insight tool. It is not intended to diagnose, treat, cure, prevent, or mitigate any disease or medical condition, and does not replace nutritional therapy assessment or advice.
Over in 15 Seconds
Quick enough to slot into a consultation without eating into treatment time, and simple enough to run from a stand at a sports club open day or a wellness fair. No blood draw, no lab, no waiting on results.
Spectral Rai Technology
A single fingertip placement captures over 700,000 individual light measurements through hyperspectral absorption, reading carotenoid and antioxidant-related activity in the skin.
One Score, Not a Data Dump
An AI algorithm referencing Raman spectroscopy distils those readings into a single Prysm Score between 100 and 1000 - a plain-English result you can explain in a sentence, not a lab report to interpret.
A Reason to Follow Up
Clients track their score between visits in a connected app, which reinforces whatever you have recommended and gives you a genuine, non-clinical reason to check back in.
Backed by Real Research
Over 20 years of Pharmanex (a division of Nu Skin) R&D sits behind it - 110 clinical studies, 180 white papers, and 18 global patents. This is health-tech with a paper trail, not a wellness gadget.
Six Signs Prysm iO Is Worth a Look
There's no single "right" kind of nutrition practice for this - it tends to suit practitioners who already work from evidence and want clients to see their progress too. See if any of the following sound like you.
Performance & Sports Nutrition
Athletes and gym-goers already obsess over numbers. For that caseload, a wellness score gives active clients another measure to chase alongside their training and fuelling plans.
Integrative & Multi-Disciplinary Practices
Where nutrition sits alongside physiotherapy, osteopathy, or personal training under one roof, a shared wellness score gives every practitioner in the building a common reference point.
Food-First Practitioners
If your protocols already lean on colourful plants, fibre, and whole foods, a scan replaces "eat more veg" with a specific, client-owned number to work towards.
Practitioners Who Do Their Own Outreach
If you already run workshops, corporate wellness days, or stalls at local wellbeing fairs, a scanning device gives you something people actively queue up for, not just a leaflet to hand out.
Family & Whole-Life Practices
Nutrition clients range from young families to people well into retirement. A wellness score works as a shared, easy-to-grasp language across that entire age range.
Solo Practitioners Wearing Every Hat
Running the practice single-handed leaves little room for anything that adds admin. A scan takes under a minute to run and needs no extra staff, training, or consultation time to offer.
Ticked a box or two?
That's usually enough of a signal. The next step is a short, no-obligation conversation to work out whether Prysm iO actually fits your practice.
Every Client You've Ever Advised Could Still Be Paying You.
Most nutritionists recommend a supplement and hope it sticks. Prysm iO makes the case every time you scan - because the client isn't taking your word for it, they're watching their own score move. Someone who can see the evidence doesn't need convincing to keep taking what's working, even long after their final consultation. That's not a one-off commission. That's a subscriber you keep earning from, quietly, in the background, for as long as they keep believing what their own number is telling them.
Proof, Not a Pitch
You're not asking anyone to take a supplement on faith. Their own scan shows the score moving, so the case for staying on it is one they make to themselves.
A Subscription, Not a Session
A programme of consultations ends. A subscription someone believes in doesn't need reminding, re-booking, or re-selling - it just keeps renewing on its own, on your books.
You Never Touch a Payment or a Parcel
Once someone's on a subscription, that's ours to run - not yours. We take the payment, we ship the product, we handle any query about a delayed order or a card that's declined. You're not chasing renewals or fielding "where's my delivery" messages. Your only involvement is seeing the commission landing in your account every week following each recurring shipment.
The Client Leaves. The Income Doesn't.
Someone moves away, completes their programme, or simply takes a break between consultations. If their scans already sold them on the product and they've watched their score increase and increase, they stick with their subscription - and you carry on getting paid for it.
What Could This Actually Add to Your Practice?
Plug in figures that reflect how you'd actually run this, and see the potential income from scan fees, retail profit, and commissions as your subscriber base grows.
The earnings shown are entirely built from scans run in your practice and the resulting supplement subscriptions taken up by your clients. The 5-year figure assumes 10 scans a week, every week, without letting up. Most practices won't sustain that pace for five years straight. The biggest challenge will be finding enough clients to scan to reach your goals, but if you're one of the determined ones who do, this is what that consistency is actually worth.

“The same scientists who helped pioneer organ-transplant medicine and the first oral contraceptive are behind the science in this device.”
Your own credibility rests on evidence-based training and voluntary registration with bodies such as BANT and the CNHC. Prysm iO comes from a similarly evidence-led background: two decades of Pharmanex research recognised by the Titan Awards, Globee Business Awards, Good Design Award, and Big Innovation Awards in 2025 - not a supplement pitch dressed up as science.
Yale Public Health Spent a Decade Proving This Isn't Guesswork
The underlying skin-scanning science behind Prysm iO was independently validated by Yale School of Public Health, whose 2013 review called it “an attractive biomarker for use in human studies” that is “highly reproducible and valid.”

A Device People Queue Up to Try
Prysm iO earns its keep outside the practice too. Take it to a corporate wellness day, a health and wellbeing fair, or a nutrition conference, and it becomes a genuine draw - something people want to try, not just watch you demonstrate. Every scan given is a warm introduction to your practice.
Draw a Crowd
A glowing scanning device on a table does more work than a leaflet stack ever could - at a corporate wellness day, a local wellbeing fair, or a nutrition conference.
Give Something Real
A free 15-second scan costs the visitor nothing but a minute of their time, and they walk away with an actual result instead of a flyer they will bin later.
Open a Conversation
The score itself does the talking - a natural, low-pressure opening to explain what you do and how working with a nutritionist could fit into their week.
Close the Loop
Capture their details alongside the scan, and you are following up with someone who already has a personal, specific reason to book a first consultation.
