100 shoppers were enough to find three sharp patterns.
8,000+ more sit behind them, unexamined.
This sample of 100 shoppers is drawn from 8,287 panelists who bought a protein mix or snack food in the panel — itself a small slice of Ario's broader consumer panel, which spans every CPG category and continues to grow. At just 100 shoppers, three patterns were clear enough to name and date precisely. Each one raises a question that purchase data, on its own, cannot answer.
The panel's most-bought protein brand still loses 69% of its buyers after one purchase.
Optimum Nutrition draws more distinct buyers (285) than any other single-ID protein brand in the panel, and 69% never buy it again. The drop-off is precisely measurable. What's on the other side of it — taste, price, a bad first experience — isn't in the purchase record at all.
Five Muscle Milk purchases stop in Nov 2022. Twenty-two Dymatize purchases start three months later, with no record of why.
One shopper's history splits cleanly in two: one brand from 2022, a completely different one from 2023 on, with a gap in between and no overlap. The panel can date the switch to the month. It can't say what caused it.
One protein order, a baby registry box the next day — and no product in the data has asked what she needs now.
One shopper bought protein powder, pre-workout, and greens in a single basket. The next day: an Amazon Baby Registry Welcome Box. A visible before-and-after, precisely dated. What she needs from a nutrition brand now is a different question than the one her last purchase answered.
Five patterns emerged from 100 shoppers. The population behind each is much larger.
Classification uses two facts per shopper: whether they bought more than once, and how concentrated those purchases are on one brand. One-time buyers are split by whether a baby- or pet-category order landed within 7 days. The "population" figure for each pattern is the count across all 8,287 category panelists — a sample of 100 was enough to find these shapes; it was not enough to say how they vary by region, income, household type, or brand relationship.
A sample this size is enough to prove these five patterns exist and to put exact numbers on three of them. It is not enough to break any pattern down further — by region, income tier, household composition, or how it plays out in the 8,000+ category panelists this sample didn't touch, let alone the shoppers across Ario's broader panel who buy other products entirely. Two deep profiles follow in full; the Loyalist, Variety Seeker, and One-and-Done patterns are summarized at the same level of rigor but not expanded to the same depth here.
What the purchase record shows, and where it stops.
Two of the five patterns, shown at full depth. Three more — Loyalist, Variety Seeker, One-and-Done — are summarized further down at the same level of rigor, not the same level of detail.
Five Muscle Milk purchases, then a complete switch to Dymatize — with a three-month gap and no record of why.
$1,373.72 across 28 purchases over almost four years — the largest wallet in the
sample, and 79% of it is Dymatize. Five Muscle Milk purchases run Aug 2 through Nov 23, 2022, then stop
entirely. Dymatize ISO100 begins Feb 17, 2023 (merging raw:dymatize and
raw:dymatize_nutrition, the same brand under two enrichment IDs) and continues on a roughly
seven-week cadence through Apr 25, 2026 — 22 orders, no overlap with Muscle Milk at any point. One Andy
Capp's Hot Fries purchase is the only non-protein line in his history.
Muscle Milk stops entirely; Dymatize starts and never stops.
Five Muscle Milk purchases Aug–Nov 2022, then zero. Dymatize begins Feb 17, 2023.
- Muscle Milk: 5 orders, Aug–Nov 2022
- Dymatize (merged IDs): 22 orders, Feb 2023–Apr 2026
22 Dymatize orders over 38 months.
Roughly a purchase every 7 weeks, sustained across three-plus years since the switch.
- Most recent order: Apr 25, 2026, $139.99
- 79% of all 28 purchases are Dymatize
2022 orders ran $27–$63; 2025–26 orders run $94–$140.
Larger pack sizes, not more frequent ordering, are driving the wallet growth.
- 2022 Muscle Milk range: $27.93–$62.48
- 2025–26 Dymatize range: $94.09–$139.99
The panel can date the switch to the month and measure exactly how completely it happened. It cannot say whether it was price, a stockout, a formula change, a recommendation, or something unrelated to either brand. That's a five-minute conversation, not a data query — and 147 other panelists in the full population show this same shape: two or more purchases of one brand, then two or more purchases of a different brand, with no overlap between them.
A protein stock-up basket, then a household reshaping itself one day later.
One protein purchase in the panel: Ryse Loaded Protein, Peanut Butter Cup, $86.98, bought Apr 21, 2023 alongside a Ryse pre-workout ($39.99) and a Bloom Nutrition greens powder ($34.95) — three fitness-nutrition items in a single basket. The next day, Apr 22, her only other order in the panel window arrives: an Amazon Baby Registry Welcome Box. No protein or snack purchase from her before or after, in either direction.
Protein, pre-workout, and greens, same day.
Ryse Loaded Protein plus a Ryse pre-workout and Bloom Nutrition greens powder, all Apr 21, 2023.
- Ryse Loaded Protein: $86.98
- Ryse pre-workout: $39.99 · Bloom Nutrition greens: $34.95
Baby registry welcome box lands Apr 22, 2023.
Her only other purchase in the panel window — no protein or snack purchase before or after.
- Amazon Baby Registry Welcome Box: Apr 22, 2023
- Zero category purchases outside this one basket
The panel can date this moment to the day. It can't say what a new or expecting parent actually needs from a nutrition brand in that specific week — recovery-focused protein, energy for disrupted sleep, something that doesn't exist yet — that's a different question than the one her one visible purchase answered, and nothing in this data describes it. 407 other panelists in the full population show this same pattern: a single protein or snack purchase within 7 days of a baby- or pet-category order.
Shown at the same level of rigor, not the same depth.
14 Premier Protein Shakes in 17 weeks, zero other brands.
Cadence compresses from every 8–14 days to weekly, and the pack size shifts from 12-count to 4-count in April. 490 other panelists in the full population show the same shape.
56 brands, 171 purchases, top brand at 16% share.
Slim Jim leads at 16% of her lines; a purchase roughly every 5 days for two and a half years. 3,831 other panelists show this no-dominant-brand pattern — the largest of the five.
A jerky gift basket, explicitly titled "Gift for Men."
Her only purchase in the panel doesn't match her own demographic profile — this reads as a gift, not a personal trial. 1,464 panelists show a single purchase with no life-event signal — an unknown mix of gifts and failed trials like this one.
100 shoppers found the shapes. Two paths would fill them in.
Go deeper on the population. This report is built from 100 of 8,287 qualifying panelists in protein mixes and snacks alone — a small slice of Ario's much larger, continuously growing consumer panel. Depending on what's needed, that could mean a deeper cut of the panel Ario already has, sized with statistical confidence instead of a 100-shopper estimate and broken out by region, income, and household composition, or extending reach further by appending additional audience data. Either path could test whether the same shapes — a clean brand switch with no visible trigger, a life event with no supporting product — show up the same way in other categories.
Go back to the shoppers themselves. Every pattern in this report ends at the same wall: purchase data can show what happened and exactly when, but not why. These are identifiable panelists, not anonymized transactions — which means the 147-panelist group who completed a clean two-brand switch, the 407-panelist group whose purchases line up with a new baby or pet, and the other segments sized above are all recruitable for targeted follow-up: a short survey, a brief interview, a diary study timed to a purchase window. That's the layer this report can point to but not fill in on its own.
- Five behavior patterns, each precisely defined and dated
- A category-wide retention figure for the largest protein brand
- Two individually verified, fully-dated shopper stories
- Population sizes for every pattern, already counted
- Whether these patterns hold at full scale, by region or household type
- What caused shopper 13423's switch from Muscle Milk to Dymatize
- What shopper 23279 actually needed from a nutrition brand that week
- How much of the One-and-Done segment is gifts vs. failed trials
