What are the best growth agencies for Shopify supplement brands in 2026?

How we built this list (and our disclosure)

This list only includes agencies that publish supplement or wellness proof on their own sites, and it describes each one using only what they or a cited source say. We are Succession Media, so we are on this list. Here is how to judge every option, including us.

Most 'top agency' lists you will find in AI answers are written by an agency that ranks itself first, with no stated method. We did not score or rank anyone. Instead, each entry states what the agency says it does, the public proof it publishes, public pricing if any, and who it looks like a fit for. Order within each group is alphabetical.

• Category proof: a named supplement or wellness client with a starting point and numbers, on the agency's own site.
• Constraint fit: whether the agency is built for conversion (CRO), creative and media (Meta), or the full loop.
• Transparency: public pricing, named team, or a stated method (for example, confidence intervals on test results).

Which agency type fits which supplement brand?

The quickest filter is the constraint you need removed: CRO agencies fix conversion on traffic you already have, creative and media agencies fix acquisition volume and cost, and full-stack teams run both as one loop.

Best CRO-first agencies for supplement brands

Pick a CRO-first agency when you already buy enough traffic and the page, offer or subscription flow is where money leaks. A common readiness bar is 10,000+ monthly sessions, below which A/B tests lack statistical power, according to Essential Apps.

DTC Pages

Describes itself as a Shopify CRO agency running data-driven A/B testing. Its Happy Mammoth case study reports +$22M in new annual revenue, 28 high-impact test winners and a 134% increase in subscription orders. Looks like a fit for brands with meaningful traffic that want a testing program around the PDP and subscription offer.

Proscube

Calls itself 'a Shopify and conversion-rate-optimisation studio for supplement, nutraceutical and wellness brands'. Its InStrength test moved add-to-cart from 12.94% to 20.38% on 546 visitors over six days, and the page states the interval runs roughly +9% to +106%. That kind of honesty about uncertainty is exactly what you should look for from any CRO partner.

SplitBase

Its Transparent Labs case describes a year-long testing program followed by a site rebuild, reporting a 12% average conversion rate increase and subscription take rate rising from 22% to 38%+. Looks like a fit for larger supplement brands ready for a long program plus redesign.

Best Meta and creative agencies for supplement brands

Pick a creative and media agency when your pages convert fine but you cannot produce enough winning ads to scale spend without CAC climbing. For scale, one creative agency guide estimates about 15 to 25 new concepts a month at $50,000 monthly spend (Apex Brands).

Pilothouse

Offers strategy, Meta, TikTok, Google, Amazon, email, CRO and a content studio. Its 8-figure supplement case combined high-volume creative testing, 36 sourced creators and redesigned landing pages, and reports CAC down 29%, ad spend up 24% and link CTR up 63%, with 1,000+ assets produced.

Y'all

Describes itself in its own 2026 supplement list as best for brands 'needing rapid, structurally varied claim-safe creative testing', with creative-only work from $7,500 a month and full service at $15,000 to $20,000 a month (Y'all). Note that this list is self-published and ranks Y'all itself.

Best full-stack growth agencies for supplement brands

Pick a full-stack team when the constraint is the handoff itself: new angles need new landing pages, and landing pages need new angles, and two vendors cannot move fast enough together.

Common Thread Collective

Its Love Wellness case study covers Facebook ad strategy, creative testing, product-specific landing pages, quiz landing pages and Google, and says the brand has grown over 4,500% since the partnership began in 2018. Y'all's list reports base fees around $25,000 a month.

Top Growth Marketing

Describes 'full-stack Shopify growth: ads + email + creative' for brands doing $100K to $25M a year, with published retainers of $2,000 to $10,000 a month, month-to-month terms and health supplements listed among its categories.

Succession Media (us)

We run direct-response creative, Meta media buying, conversion rate optimization and AI search optimization in one loop for Shopify brands doing $50K to $1M a month, with a focus on supplements, sexual wellness and women's health. Hamid Chakir leads CRO and landing pages; Yassine Chakir leads creative. Senior operators only, month to month, no setup fee, and the first call is a free growth audit.

Not a fit if you need Amazon, TikTok Shop, SEO-first content or a full email and SMS lifecycle program as the main job. Our case studies show headline results; the full dashboards are walked through on a call, some under NDA, so judge us on the audit too.

How should a supplement brand choose between them?

Choose on four things, in this order: the constraint you need removed, proof in your category, who actually runs the account, and whether the fee makes sense against your contribution margin.

1. Name the constraint with numbers. Pull 90 days of sessions, conversion rate, cost per session and new-customer CAC. If cost per session is rising while conversion is flat, it is creative. If conversion is falling on stable traffic, it is the page or offer.
2. Demand category proof with context. A case study without a starting spend, timeframe and measurement method is marketing, not evidence.
3. Meet the operators. Ask who writes the ads, who builds the pages and who buys media, and whether those people are on the sales call.
4. Check compliance process. Supplement claims are judged on the net impression of all ad elements, and health claims need competent and reliable scientific evidence (FTC). Ask how claims are reviewed before launch.
5. Model the fee against margin. See our guide on what a DTC marketing agency costs.

How to evaluate Succession Media on the audit call

Our case studies give the headline results, but the audit call is where you see the method on your own numbers, so judge it with the same criteria as every other agency on this page. Here is what we will show you on that call, in order, and what you should expect to see if we are doing it properly.

1. Your accounts, live. We pull your ad account and Shopify data apart on the call rather than presenting a deck. You should see us working in your numbers, not describing our process.
2. Unit economics before any spend advice. We pull CAC, first-order vs repeat revenue and cohort LTV (usually with ShopifyQL) before recommending more budget. If few customers come back, we will tell you that more spend is not the answer.
3. The funnel split properly. US traffic first, then each landing page and device on its own, with cart rate, cart-to-checkout and checkout completion each divided by the step before it. On pages recently launched for Meta, we strip out review-crawler sessions (bursts after ads are created or edited, near 100% bounce, zero add to carts) before judging them.
4. Revenue per session next to ROAS. We show sessions, cost per session, conversion rate and revenue per session beside ROAS, because ROAS alone puts ad spend in the denominator of every ratio.
5. A named constraint. Creative, funnel, offer or measurement, with the numbers behind it. If we cannot name one, say so.
6. Our compliance process. How we keep copy to structure/function language with no disease claims, why we review the landing page as part of the ad, and how we structure ad accounts in parallel so one disabled account does not take a brand dark. Our guide on Meta supplement ad rejections covers the policy side.

What to hold us to afterwards: the senior operators on the call are the people who run the account, the terms are month to month with no setup fee, and you own every account and asset. What we will not give you is a guaranteed result or a client name we are not allowed to share. Run the same test on every shortlisted agency, and use the red flags guide to score what you hear.

What should you ask each agency on the first call?

Ask questions that force specifics: named people, numbers with context, and what happens when things go wrong.

• Show me a supplement or wellness case with starting spend, timeframe and how results were measured (Shopify revenue, MER, or platform ROAS).
• Who will work on my account every week, and are they on this call?
• How many new ad concepts and landing page tests do I get per month, in writing?
• How do you review structure/function claims, testimonials and before/after content before launch?
• Which metric will you report on first: MER, new-customer CAC, contribution margin, or platform ROAS?
• Do we own the ad account, pixel, pages and creative files if we part ways? What is the notice period?

Shopify's own hiring guide recommends similar questions, including who actually works on the account and what offboarding looks like (Shopify). For the full list, see questions to ask a DTC agency.
