You Can't Sell More Hours.
You Can Sell This.
Every PT hits the same wall eventually - your week only has so many training slots in it, and once they're full, that's the ceiling. Prysm iO is a 15-second scan you run at the start or end of a session, turning your clients' nutrition and lifestyle habits into a number they can watch move - and turning that same 15 seconds into an income stream that doesn't need a single extra hour in your day.
- Runs inside a session you're already delivering - no extra time, no new admin
- No new certification, no premises, no equipment beyond the device itself
- Gives plateauing clients a number to chase when the mirror stops changing
No sales script, no contract on the call - just enough to decide if it's worth trying.
A Full Diary Isn't the Same as a Growing Income
Training is a time-for-money business by design - you get paid for the hour you're in the room, not a minute more. That's fine until your week is genuinely full, and then the only options left are working longer days or pushing your rate past what local clients will pay. Prysm iO doesn't ask for more of your time. It turns a 15-second scan you already have room for into a second income stream - one that keeps paying out through subscriptions long after the session ends.

Is Their Diet Actually Supporting Their Training?
Ask a client how their diet is going and most will say "pretty good." Recovery nutrition rarely survives the gap between a supermarket shelf and a plate, though, so a solid training plan can be quietly let down by what actually gets eaten.
So they take a supplement. Then what?
Plenty of clients already pop something daily on faith - a tub, a habit, a hope it's helping their training - with zero feedback on whether it is actually working. If you are programming their sessions, you can give them a real answer instead of a guess.
Give them a baseline, not an assumption
A 15-second scan gives a client their own carotenoid score, a genuine personal number rather than generic nutrition advice, and it is something you can track alongside the metrics you already log.
A guarantee, not just marketing
A score with room to climb is exactly what the Pharmanex Certified range is designed for, and there is a real guarantee behind 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.
Swap the "pretty good" for a number, and pair it with a range built to move it.
What You'd Actually Be Recommending
Clients keep asking what they should be taking, and 'a bit of everything' is not much of an answer. The Pharmanex range is built around carotenoids and other nutrients that come up constantly in fitness and nutrition conversations, and its formulas are designed to be highly bioavailable, so what a client takes is what their body has the best chance to use.
Lutein and other carotenoids
Lutein is included in products across the range in a highly bioavailable form, alongside other carotenoids. They are the same family of pigments the scan reads in the skin, which is why a client's score can show whether their intake is building up.
Omega-3: EPA and DHA
Marine Omega supplies EPA and DHA, which support normal heart function as part of a varied diet, an easy fit alongside a training plan.
Vitamins and minerals
The 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 who struggle to fit enough produce into a busy week.
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.
Test Their Current Stack, Then Track the Switch
Scan a client who is taking another brand to set a baseline. If they decide to move to a Prysm-certified product, re-scan them every few weeks and let their score show whether it is working. 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 something they take on trust.
100 Million Healthy Households
Plenty of clients will want a device of their own, so they can re-scan at home, scan family members too and even compete for the highest score. Nu Skin's stated aim is 100 million healthy households, each with a Prysm device and a shared habit of better nutrition and supplementation, and you can be the one who starts that in theirs.
If a client's supplement was advised by their GP or another clinician, it should only be changed with that clinician's agreement. The score is a wellness reading, not a reason to stop or swap 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 medical advice. Please check each product's label for its exact ingredients and amounts.
The Four Things Every PT Asks First
This works just as well for clinics with reception desks and treatment rooms as it does for how most PTs actually train: solo, mobile, hands full, no spare admin hours. Here's what usually comes up before someone decides it's worth a look.
"I don't have a clinic or a studio."
You don't need one. The device runs off a fingertip placement and an app on a phone or tablet - it works on a gym floor, in a park, at someone's house, or out of a car boot between clients. No premises and no fixtures - just the device and the app.
"I'm not qualified to give nutrition advice."
You don't need a new certification to run the scan or talk clients through their score. It's a wellness reading, not a diagnosis or a meal plan - you're handing someone a number, not writing them a prescription.
"I don't have time for more admin."
There isn't any to add. The scan takes 15 seconds inside a session you're already running - no separate appointment to book, no paperwork, and the only thing to learn is the app, which your client can then check on their own time.
"I train solo - is this even worth it for one person?"
Yes. This isn't a gym-chain tool that needs a big client roster to pay for itself - one device covers everyone you see in a week, whether that's three clients or thirty, mobile or fixed-location.
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 your 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 straight into the coaching conversation you're 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's as much at home on a gym floor or in a park as it would be in a clinic.
Prysm iO is a wellness insight tool. It is not intended to diagnose, treat, cure, prevent, or mitigate any disease or medical condition, and it is not a substitute for medical or dietetic advice.
Over in 15 Seconds
Quick enough to slot into a warm-up or cool-down without cutting into the session itself, and simple enough to run out of a bag at a park bootcamp. 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 - something you can explain in one sentence between sets, not a report to sit down and interpret.
A Reason to Follow Up
Clients track their score between sessions in a connected app, which reinforces whatever you've recommended and gives you a genuine, non-awkward reason to check in outside your normal session times.
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.
Clients Don't Leave Because They Stopped Caring.
They Leave Because They Stopped Seeing Progress.
The clients you lose are rarely the ones having a bad session - they're the ones who quietly decide the plan has stopped working, usually right around a plateau you could see coming but they couldn't. Prysm iO gives you a second, faster-moving metric to point to when the scale or the mirror goes quiet for a few weeks.
The Scale Stopped Moving. Their Score Didn't Have To.
Weight plateaus long before someone's actually stalled - strength, sleep, energy, and recovery all keep shifting underneath it. A wellness score gives a plateauing client something else to watch move, right when the mirror and the scale go quiet.
A Number Is Harder to Walk Away From Than a Feeling
Clients who cannot see documented progress start asking themselves whether the sessions are still worth it. Clients holding a specific, trending number have a concrete reason to keep paying you to move it further.
A Built-In Reason to Re-Book the Re-Scan
Booking a follow-up scan is an easy, low-pressure way to get someone back on your calendar between programme blocks - a natural check-in that doesn't feel like a sales conversation.
Dr. Steven Moore, a physician who has worked with this scanning technology for over 20 years as a Nu Skin affiliate, puts it simply: the follow-up scan matters more than the first one. The first scan gets someone's attention - it's the second one, showing an improved score, that turns a passing sale into a client who genuinely believes it's working and stays on the programme.
Six Kinds of PT This Actually Works For
There's no single "type" of trainer this is built for - solo or group, mobile or gym-floor, in-person or hybrid. See if any of the following sound like your week.
Mobile & Home-Visit PTs
No fixed premises, no problem - the whole kit fits in a bag and runs off a fingertip placement, wherever the session happens to be that day.
Self-Employed Gym-Floor PTs
Renting floor space from a big-box gym means the gym's app and induction offer are the same for everyone. A scan is something the in-house team isn't handing out.
Online & Hybrid Coaches
If check-in photos and self-reported measurements are already part of your process, a scan adds one more objective number your clients can log themselves and send you.
Bootcamp & Group-Session Trainers
A device on a table at a park session or a bootcamp gives you something people queue up to try before you've said a word about signing up.
PTs With Plateauing Clients
If you've got clients whose weight has stalled but whose effort hasn't, a second number to track is often exactly what keeps them booking the next block.
Small Studio Owners Looking for a New Line
Running a small studio already means wearing every hat. This is retail-style income that doesn't need another staff member or another hour on the floor.
Sound like you?
That's usually enough of a signal. Grab a short call and we'll work out whether it's actually worth adding to what you do.
Every Client You've Ever Had Could Still Be Paying You.
Most PTs sell a supplement once and hope it sticks. Prysm iO sells it every time you scan - because the client isn't taking your word for it, they're watching their own score move. A client who can see the evidence doesn't need convincing to keep taking what's working, even long after they've stopped paying you to train them. 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 training package 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, stops training, or simply takes a break. 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 On Top of Training?
Plug in figures that reflect how you'd actually run this, and watch the projected income from scan fees, retail profit, and commissions build as your subscriber base grows - all without adding a single training hour.
The earnings shown are entirely built from scans you do and recommendations you give, 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 people won't sustain that pace for five years straight. The biggest challenge will be finding enough people 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.”
Anyone can call themselves a wellness coach and sell an app subscription. What sits behind the device you'd be handing clients is a different order of scrutiny entirely - two decades of Pharmanex lab work, recognised with Technology Innovation honours at the TITAN Business Awards and a Wellness Insight win at the Globee Business Awards, plus a Good Design Award for the device itself. It's a name worth borrowing when a client asks what actually backs the number on their screen.
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.”

Free Marketing That Doesn't Feel Like Marketing
Take it to a park bootcamp, a running club meet-up, or a corporate wellness day and Prysm iO does the introducing for you - people come over because they're curious about the device, not because you've pitched them anything.
It Gets People Curious
Nobody stops to watch you demonstrate a resistance band. A lit-up scanner on a table at a bootcamp or club social gets people asking what it does before you've said a word.
The Result Is the Pitch
A stranger walks away with an actual number, not a leaflet - and that number is a far better advert for training with you than anything you could say about yourself.
You Get an Excuse to Follow Up
Nobody minds being messaged about a result they asked to see. Capturing details alongside the scan turns a cold follow-up into one they were half-expecting.
