We could not verify enough current, supplement-specific first-party evidence to publish an honest top-ten list. One agency in our review had a clear named supplement paid-media case study. Three others have relevant Shopping or ecommerce capabilities, but their public pages do not prove supplement-sector experience. This page keeps those categories separate.
Disclosure: Upscale publishes this page. It is mentioned only as an adjacent-capability option because its public profile supports ecommerce and Shopping expertise, not direct supplement-sector evidence.
Evidence threshold and limits
Direct-evidence status required a named supplement client or an explicit supplement PPC proposition on the agency’s own site. Adjacent-capability status required published Shopping, feed or ecommerce work that could be relevant after the buyer separately verifies claims and policy experience.
This distinction prevents a familiar SEO-list problem: ten agencies described as sector experts when most merely offer Google Ads. Supplement advertisers should prioritise ingredient and claim governance, Merchant Center operations and contingency planning over the length of a shortlist.
| Evaluation area | Procurement test |
|---|---|
| Ingredient screening | Who checks prohibited or restricted ingredients, product naming and regulatory status? |
| Claims library | How are approved nutrition or health claims controlled across feeds, ads, images and pages? |
| Merchant Center resilience | Can the team diagnose item, destination and account-level enforcement without reckless repeat appeals? |
| Subscription economics | Do renewals, refunds, discounts and contribution shape value? |
| Portfolio contingency | Can spend move safely if a hero SKU becomes limited or disapproved? |
Shortlist supported by first-party evidence
Impression — direct sector evidence
Evidence reviewed: Impression publishes a paid-media case study for Nourished, a vitamin and supplement subscription brand. The case study discusses first-party CRM data, cross-channel attribution and subscription acquisition, providing the strongest direct evidence found in this review.
What still needs proving: Ask which people from that engagement remain available, what policy or feed work was included and how the proposed team would adapt from personalised vitamin gummies to the buyer’s ingredients, claims and countries.
Found — adjacent Shopping capability
Evidence reviewed: Found’s PPC page lists PMax, feed optimisation, paid search, YouTube and CRO. Those capabilities can be relevant to supplement ecommerce, but the cited page does not demonstrate supplement-specific policy experience.
What still needs proving: Keep Found on the longlist only if it can supply a current supplement reference or complete a credible ingredient, claim and Merchant Center workflow exercise.
DPOM — adjacent ecommerce capability
Evidence reviewed: DPOM has a dedicated UK ecommerce and Shopping proposition. It may fit a smaller retailer needing feed and campaign management, but the public evidence reviewed is category-general.
What still needs proving: Ask who handles healthcare-policy disapprovals, how claim changes are approved and whether the team has managed products with similar ingredients and restrictions.
Upscale Digital — adjacent specialist capability
Evidence reviewed: Luke Bright’s profile states ecommerce, Google Shopping, PMax and margin-led bidding expertise. It does not claim supplement specialism, so Upscale should not be selected on sector authority without further evidence.
What still needs proving: Require a product-policy audit and relevant references. The founder-led model may provide senior attention, but it does not replace regulatory or ingredient expertise.
Treat claims as controlled product data
Create an approved-claims register before scaling feeds. For each product, record ingredient status, authorised nutrition or health wording, evidence owner, countries, prohibited phrases and required qualifiers. The register should feed product titles, descriptions, image text, ads and landing pages so one risky claim is not removed in only one surface.
Google Merchant Center can restrict unapproved pharmaceuticals and supplements and products associated with regulatory action. CAP Code Section 15 addresses food and supplement nutrition and health claims in UK non-broadcast advertising. Product legality does not by itself guarantee Google eligibility, and Google approval does not establish compliance with UK advertising rules.
Plan for enforcement before it happens. Keep revenue concentration by SKU visible, maintain clean appeal evidence, avoid repeated review requests before fixes are complete and define which products can absorb budget. An agency promising to bypass policy is creating account risk, not solving it.
Match the brief to the risk
| Brief | Core requirement | Decision emphasis |
|---|---|---|
| Single-category supplement brand | Short specialist shortlist | Prioritise claims control and relevant ingredient experience |
| Large catalogue | Feed governance plus policy operations | Versioned rules, product diagnostics and portfolio risk reporting |
| Subscription business | Customer-value measurement | Cohorts, churn, refunds and contribution-aware acquisition |
| International expansion | Country-by-country review | Separate claims, eligibility, language and Merchant Center status |
Questions for a working session
Share the ingredient list, approved claims, feed sample and recent Merchant Center issues before asking:
- Which of our ingredients require extra review?
- Show how one approved claim reaches every advertising surface.
- Who can authorise a feed-title change?
- What evidence is collected before an appeal?
- How are refunds and subscription renewals valued?
- Which products create concentration risk?
- What current supplement clients can be referenced?
- When would you recommend not advertising a product?
Put governance into the contract
A supplement brief should allocate ingredient review, claims approval, feed publication and Merchant Center appeals. No agency salesperson should be able to override the advertiser’s regulatory decision.
Supplement brands should own feed sources, claims registers and Merchant Center access. The opening phase should reduce policy and catalogue risk before it pursues extra volume.
Worked procurement scenario
A supplement brand depends on one hero SKU for half of Shopping revenue. Merchant Center limits the product after a new landing-page claim is published. The agency must pause affected promotion, trace the claim across feed, image, ads and page, verify ingredient and policy status, implement approved language and prepare review evidence. Impression has direct supplement evidence; the adjacent options need to prove this workflow before appointment. The commercial plan should also show where budget moves if the SKU remains ineligible, rather than assuming a successful appeal.
During reference calls, ask about actual Merchant Center enforcement, not only ROAS. How did the agency identify a claim or ingredient problem, coordinate legal review and preserve unaffected products? Confirm who wrote feed rules and whether the client retained them. Policy operations are easier to promise than demonstrate.
The appointment should include a quarterly product-policy review because ingredients, claims, packaging and destination copy change. Tie the review to the product launch calendar so advertising eligibility is assessed before stock and creative are committed, not after Merchant Center rejects the feed.
