Supplement Brand CAC and ROAS Benchmarks for 2026: What Good Ad Performance Actually Looks Like
Your ad agency just sent this month's report. Cost per acquisition looks high.
ROAS looks average. Is that normal, or is your agency underperforming?
Most supplement brand owners have no idea what a "good" number actually looks like in this category. Supplement CAC is naturally higher than almost any other ecommerce vertical.
That is not always your agency's fault. But sometimes it is.
This guide breaks down the real 2026 benchmarks for supplement brand CAC and ROAS, so you can tell the difference.
Quick Look
Supplement brands see some of the highest CAC of any ecommerce category, often $45 to $100+ per new customer, because of ad compliance limits, skepticism, and heavy competition.
A blended ROAS of 3x to 4x is typically considered healthy for prospecting-heavy accounts. Retargeting alone can look much higher, which is why blended numbers matter more than any single campaign.
If your agency cannot explain why your numbers sit where they do, that is a bigger warning sign than the numbers themselves.
Why Supplement CAC Runs So High
Supplement ads live under some of the tightest rules on Meta and Google. You cannot make aggressive health claims.
You also cannot promise specific results.
That restriction alone pushes creative costs and rejection rates up compared to almost any other product category.
Add in consumer skepticism (everyone has been burned by a supplement that did nothing) and a crowded market, and you get a category where paying $60 to $90 to acquire one customer is often just the cost of doing business.
Industry benchmarking data from 2026 puts the average supplement and wellness CPA around $89, with a typical range of $61 to $127 depending on sub-category and platform. A separate Meta-specific benchmark set puts supplement and health CPA closer to $45 to $75, reflecting how much platform mix and targeting can move the number.
Both can be true at once. Benchmarks vary by methodology and how a brand defines "acquisition."
Use them as a range, not a scoreboard.
2026 CPA Benchmarks by Supplement Sub-Category
Not every supplement product costs the same to acquire a customer for. Here is how the category typically breaks down, based on aggregated 2026 industry benchmarking data.
| Sub-Category | Typical CPA |
|---|---|
| Protein powders | $68 |
| Vitamins and minerals | $78 |
| Sports nutrition | $72 |
| Greens and superfoods | $91 |
| Functional supplements | $94 |
| Sleep and stress | $97 |
Figures are aggregated 2026 industry benchmarks, not eBrandX client averages. Actual CPA moves with offer, audience, creative, and traffic quality.
See our 2026 ad spend benchmark guide for how much budget typically supports these numbers.
The real math problem: high CPA against a modest average order value makes first-purchase profit nearly impossible for most supplement brands. If your agency is not building toward subscriptions or repeat purchase as the profit engine, the CAC conversation is incomplete.
2026 CPA Benchmarks by Ad Platform
Sub-category is not the only variable. Where you spend the money changes the number too.
| Platform | Typical CPA |
|---|---|
| Google Shopping | $76 |
| TikTok | $81 |
| YouTube | $88 |
| Meta (Facebook and Instagram) | $92 |
| Google Search | $94 |
Notice that Google Shopping and TikTok tend to run cheaper than Meta and Google Search for this category. That does not mean you should abandon Meta.
It usually means your funnel mix matters more than any single platform's average.
A brand spending 90 percent of its budget on the most expensive platform, with no TikTok or Shopping presence at all, is often leaving cheaper acquisition on the table. That is a mix problem, not just a creative problem.
What Counts as a Good ROAS in 2026
ROAS gets thrown around as one number, but it is really three different numbers wearing the same name.
A healthy blended ROAS for a supplement brand running full-funnel campaigns typically sits between 3x and 4x. That blends everything: cold prospecting, warm retargeting, branded search, all of it.
Prospecting-only ROAS (brand new, cold audiences) is usually much lower, often 2x to 3x, because you are paying to introduce your brand to someone who has never heard of it.
Retargeting ROAS can look excellent, sometimes 6x to 10x, because you are only spending on people who already know your brand.
"If an agency only shows you the blended ROAS, ask to see it split by funnel stage. A brand can look profitable overall while its cold traffic is quietly losing money every single day."
This is exactly why a single ROAS number tells you almost nothing on its own. You need it broken down, alongside CAC, AOV, and creative refresh rate.
We covered that last piece in our creative testing velocity guide.
5 Questions That Reveal If Your Numbers Are Actually Good
A raw number means nothing without context. Ask your current agency (or a prospective one) these five questions before deciding anything.
- What is our CPA broken down by sub-category and platform, not just as one blended average?
- What is our prospecting ROAS versus our retargeting ROAS, shown separately?
- How many new ad concepts launched last month, and how does that compare to our CPA trend?
- What percentage of revenue is coming from repeat customers versus first-time buyers?
- What would need to change to improve these numbers in the next 90 days, specifically?
If those answers come back vague, slow, or defensive, that is worth paying attention to. We wrote a longer breakdown of the warning signs in our agency scaling checklist, including when it is time to make a change.
Three Mistakes Brands Make When Reading These Numbers
Even with the right benchmarks in hand, it is easy to misread them. Here are the three mistakes we see most often.
Mistake one: comparing CAC across brands with different price points. A $30 product and a $90 product will never share the same acceptable CAC.
Compare your own trend line over time, not someone else's absolute number.
Mistake two: judging a campaign after three days. Meta and TikTok algorithms need time and data to optimize.
A CPA that looks bad on day two can look completely different by day fourteen.
Mistake three: ignoring LTV entirely. A $90 CAC on a subscription product with a 6-month average retention can be far more profitable than a $40 CAC on a one-time purchase.
CAC without LTV is only half the story.
What to Do If Your Numbers Miss the Benchmark
Missing a benchmark by a little is not an emergency. Missing it by a lot, for months in a row, usually is.
Start with creative. Stale ad creative is the number one cause of rising CAC in this category, because compliance-safe supplement ads wear out faster than most other verticals.
If your agency has launched the same handful of concepts for three months straight, that alone can explain a CAC climbing past benchmark.
Next, look at funnel mix. A brand pouring most of its budget into the most expensive platform, with no cheaper channel supporting it, will always look worse than the blended benchmark suggests.
Finally, look at retention. If CAC is high and repeat purchase rate is low, the math almost never works, no matter how good the ad creative is.
How eBrandX Approaches CAC and ROAS Differently
We report CAC and ROAS split by funnel stage and sub-category every single week, not buried in a monthly summary. Supplement brands we work with always know exactly where their money is going and why.
Because compliance restrictions are the single biggest driver of high supplement CAC, our creative and compliance review process is built to keep more ads live longer, which is often the fastest way to bring CAC down without touching budget.
If a brand's numbers are underperforming these ranges and their current partner cannot explain why, that is usually the first thing we diagnose on a call.

Supplement CAC is never going to look like CAC in most other ecommerce categories. That is the nature of the compliance rules and the skepticism you are working against.
But "expected to be high" and "unexplained and rising" are two very different situations. Knowing the difference is what separates brands that scale from brands that quietly bleed ad spend for a year before switching agencies. Want more benchmarking breakdowns like this?
