A coach recommends a brand to a client. The client buys it. Everyone is pleased. The question that decides whether any of it mattered is the next one: does the same coach recommend it again, to a different client, six months from now? A recommendation made once is a trial. A recommendation that keeps happening is a position, and in a quarterly sales report the two are indistinguishable.
That persistence is what we mean by recommendation stickiness. It is the question brands ask most often once they accept that this layer exists, and honesty first: it is not a number we can give you yet. The cut that would size it, surveyed professionals asked which brands they recommend and whether those names recur, has not been run. The instrument that has been fielded asked about categories, not brands. What follows is what actually makes an endorsement hold, and what to watch while the measurement catches up.
The short answer
Recommendation stickiness is whether a professional's endorsement of a brand persists across the clients they guide and over time. It is not yet quantified in a published cut: the fielded survey asked which categories coaches recommend, not which brands they keep recommending. Stickiness is the difference between being chosen once and being chosen by default.

Where the figures on this page come from
Source. An internal research project across the hale ecosystem, which serves more than 40,000 fitness and health professionals and their clients. Findings combine a voluntary practice-profile survey (985 usable responses) with platform activity across a 90-day window in 2026.
Definitions. The recommend rate is the share of surveyed professionals who report recommending one or more supplement categories to clients. It is a category-level measure. It says nothing about which brands are named, and the survey did not ask.
Scope. A read of a professional network, not a census of the entire non-clinical workforce. The ecosystem sample skews towards independent, digitally engaged practitioners, so read it as a directional baseline. Figures are rounded.
Privacy. Everything is aggregated and anonymised. No individual coach, client or business is identifiable, and no personally identifiable information is included.
What stickiness means at the recommendation layer
Brand tracking usually asks how many people know a brand, and how many would consider it. At the recommendation layer there is a third question that matters more than either: how often does the same professional come back to the same brand? Reach tells you how many coaches have your brand in front of them. Stickiness tells you how many of them keep it there.
The two behave differently. Reach can be bought, at least for a while, with sampling, education and a well-run partnership. Stickiness cannot. It is the sum of a hundred small judgements a coach makes between sessions, and it moves slowly in both directions, which is exactly why it is worth watching. A brand being recommended once and dropped looks healthy on any measure of activity while it quietly loses the layer that decides its category.
That the layer moves purchases at all is not in dispute, and the evidence sits in Do Fitness Professionals Influence What Clients Buy?. What that evidence does not tell anyone is how loyal the recommending is.
What makes an endorsement hold
Three forces do most of the work here, and none of them is persuasion in the ordinary marketing sense.
The coach's own repertoire. Most professionals work from a short list they know well, and that list is hard to enter but sticky once entered. A brand that gets onto it becomes the answer the coach reaches for without thinking, because recommending something unfamiliar carries a cost. The coach has to be able to explain it, defend it, and follow up when a client has a question. Familiarity inside a coach's repertoire is the strongest form of stickiness there is, and it is built one satisfactory client outcome at a time.
Fit with the advice already being given. A recommendation lasts when it slots into a story the coach is already telling. Protein fits a conversation about recovery; a sleep product fits a conversation about training load. A brand that requires the coach to rearrange their programme in order to justify it tends to be recommended once and quietly dropped, not because it failed but because it asked for too much room. The practical test is whether the product makes the coach's existing advice easier to deliver.
Repetition, which is what turns a recommendation into a default. A client hears a brand name from their coach, tries it, and hears it again a few weeks later. By the time it has come up across a handful of sessions it has stopped being a recommendation and become the answer. This is ordinary memory at work, and the mechanism is the one the Ehrenberg-Bass Institute calls mental availability, set out in Byron Sharp's How Brands Grow (2010). It applies to the professional doing the recommending as much as to the client receiving it.
The double jeopardy problem, applied to a recommendation layer
The Ehrenberg-Bass Institute has documented a pattern across categories that it calls double jeopardy, and it makes uncomfortable reading for any challenger brand. Smaller brands suffer twice: they have fewer buyers, and those buyers are slightly less loyal than the buyers of a larger brand. Loyalty, on this evidence, follows penetration rather than driving it.
We are not aware of that pattern being tested at a professional recommendation layer, because testing it needs a panel holding both the professional and the client, and very few exist. hale's panel is an instrument that could, and the prediction is not encouraging for a brand running third in its category. If double jeopardy holds here, the brand with fewer recommending coaches would also get less persistent endorsement from each of them, so a modest gap in reach would widen over time instead of closing. That is a prediction from published theory, not a finding. This cut has not been run on our panel, and we will not put a number on it until it has.
The honest caveat: brand-level stickiness is not measured yet
Answering the question in this page's title takes two things, and neither is a shortcut. The survey would have to ask professionals which brands they recommend rather than which categories, and it would have to ask the same professionals again in a later wave, so that recurrence is observed rather than inferred. That is a longitudinal, brand-level read, and it is not the read that has been fielded. The published instrument is category-level: roughly seven in ten coaches recommend at least one supplement category to their clients, drawn from 985 usable responses over a 90-day window in 2026. That tells you the layer is busy. It does not tell you how faithful it is.
A vague version of stickiness, described in the abstract for another thousand words, would be worth exactly what you paid for it. The useful version has to come off the panel, and it has to survive the obvious objection, that a coach naming a brand once in a survey is not the same as a coach recommending it in a session. Reading the professional and the client together is the discipline that closes that gap, and the method behind it is in Both Sides of the Sale. Until that read exists, the honest position is that stickiness is structural, visible in how professionals talk about their own repertoire, and unquantified in public.
What to do before the cut is run
Two moves are worth making now, and neither needs a new dataset.
Start treating repeat recommendation as the measure you care about, and first mention as merely the door. Most brand-side reporting on this layer stops at awareness among professionals, which is a reach measure, and reach is the half of the problem a competitor can buy their way into. Asking your own professional community which products they have recommended more than once this month will not be method-stamped research, but it will tell you which direction the number is moving.
Then look for the friction that breaks the habit. Endorsements rarely die from a bad review. They die from small operational irritations: stock that runs out, a price that needs explaining, a claim that makes the coach do more work than the recommendation is worth. Those are fixable, and they are invisible to a tracker that only asks whether anyone has heard of you. The measures worth pairing with this one are in the brand health metrics guide.
Measure it continuously rather than annually, too. Stickiness is a rate, not a level, so the interesting information is whether the same professionals are still naming you this quarter as last quarter. An annual survey turns a leading indicator into a history lesson, which is the argument for continuous tracking that the recommendation layer research sets out in full.
Find out whether your recommendation base is holding
A brand can be named by hundreds of professionals and still be drifting out of their repertoire. hale measures perception among coaches and their clients, continuously, in the markets you care about, so that drift shows up as a trend rather than a surprise.
Frequently asked questions
What is recommendation stickiness in health and wellness?
It is whether a professional's endorsement of a brand persists: across the clients they guide, and across time. A recommendation made once is a trial, while one a coach keeps making is a position. hale has published no figure for brand-level stickiness, because the cut that would size it has not been run.
Do coaches recommend the same brand consistently?
That has not been quantified in a published cut. The survey behind hale's recommend rate asked professionals which supplement categories they recommend, not which brands, so it cannot speak to brand-level consistency. The category-level figure, roughly seven in ten coaches recommending at least one category, shows the layer is active. It says nothing about how faithful it is.
How would you measure whether a coach's recommendation lasts?
It needs a longitudinal, brand-level read: the same professionals asked which brands they recommend, then asked again in a later wave, so recurrence is observed rather than inferred. Reading the professional and the client side together is what makes the result defensible. Until that cut is run and method-stamped, no figure should be stated or implied.
Published September 2026. The category-level recommend rate on this page is drawn from an internal research project across the hale ecosystem of 40,000+ professionals and their clients; brand-level recommendation stickiness has not been run or published and nothing here estimates it. Double jeopardy and mental availability are cited as Ehrenberg-Bass Institute findings, not hale's own claims. hale is a health-tech holding company; its coaching platforms, QuickCoach and FitFocus, form the network behind this research.
