§ · health · wellness

Wellness compounds. Substantiate the claim.

A supplement, functional, and nutraceutical ecommerce practice that treats claim substantiation, DSHEA compliance, and subscription retention as one operating stack. Shopify Plus builds, Amazon parallel ops, evidence-first PDP design.

§ 01 · the wellness litmus test

Five signals tell you if your wellness brand is defensible.

Wellness brands face two problems no other category has at this scale: long conversion windows that break platform pixels, and claim substantiation demands that compound as the catalog grows. These five signals tell you whether the operation is built to survive both. Measured inside your Shopify, Klaviyo, and Northbeam stacks.

signal 01 · PDP conversion

3.5%+

PDP conversion on returning visitors. Under 2% means the claim scaffolding, review density, or dose clarity is broken.

signal 02 · subscription share

40%+

Percentage of new orders that convert to subscription within 30 days. Below 25% means the cadence UX or value prop is buried.

signal 03 · claim coverage

100% cited.

Percentage of PDP marketing claims carrying a machine-readable citation. Anything under 100% is a legal and retail exposure.

signal 04 · Amazon defensive listing

Brand Registry enrolled.

Enrolled in Brand Registry with A+ content live. Missing either exposes the brand name to counterfeit listings.

signal 05 · attribution coverage

80%+ recovered.

Share of conversions captured by the four-layer attribution stack versus platform pixels alone. Under 60% means decisions run on bad data.

§ 02 · DSHEA · FDA · FTC

A claim without a citation is a liability.

DSHEA, FDA, FTC, state AG, Amazon, retailers. Six parties can ask for your substantiation file tomorrow. The brands that survive have already built the answer into the operation. Four artifacts render from the Shopify catalog.

artifact 01 · claim library

Claim maps to citation.

Every PDP marketing claim carries a reference ID tied to a substantiation file. Clinical study, ingredient monograph, or precedent decision. Machine-readable, auditable.

artifact 02 · DSHEA disclaimer

Rendered from template.

The FDA structure-function disclaimer renders on every supplement PDP from the Shopify theme. One edit, all products. Impossible to forget.

artifact 03 · adverse event log

Gorgias routes to log.

Customer service macros route adverse event reports to a structured log with timestamp, SKU, lot, and outcome. FDA-ready without a spreadsheet.

artifact 04 · regional surfaces

Prop 65, EU novel food, UK MHRA.

Geolocation at cart plus per-SKU flags render jurisdiction-specific warnings without a separate store per market.

§ 03 · the evidence-first PDP

Fewer lifestyle photos. More footnotes.

Wellness buyers now research more than they used to. The PDP that wins in 2026 leads with dose, bioavailability, ingredient provenance, and outcome-specific reviews. Aspirational imagery moves below the fold. Conversion and LTV both rise.

§ 04 · subscription tuned to dose

Cadence reads from pack size, not billing.

60-cap at 2x daily is 30 days. 120-cap at 2x daily is 60 days. A default monthly cadence doubles the second SKU up on the buyer's shelf and drives churn. Read dose and pack from metafields, set cadence per SKU.

lever 01

Dose-tuned cadence.

Per-SKU cadence derived from pack size divided by daily dose. Subscription builder writes directly from the metafield, not from a default.

lever 02

Skip, swap, pause.

Four controls, all self-service, one tap from account or transactional email. Pause without cancel. Cancel as last resort.

lever 03

Membership above discount.

Subscribe-and-save baseline plus: early SKU access, protocol guides, practitioner content, periodic free shipping. Members churn at half the rate.

lever 04

2nd-order CAC.

Second-purchase acquisition cost. When under 30% of 1st-order CAC, retention is real and the brand funds its own growth.

§ 05 · attribution under long windows

Wellness conversion windows are long. Your pixel is not.

Wellness buyers take 14 to 45 days to buy after first touch. iOS 18 ITP and consent loss drop most of that. Four layers recover the signal.

  1. 01

    Server-side tracking.

    GTM Server Side or Stape as first-party data collector. Events fire from your server, not from a browser pixel that ITP clears after 24 hours.

  2. 02

    Platform-side CAPI.

    Meta CAPI with deduplication, Google Enhanced Conversions, TikTok Events API. Send the platforms clean first-party events; they model the rest.

  3. 03

    Consent-mode v2.

    Mandatory for UK and EU traffic since March 2024. Without it, Google Ads remarketing dies and reporting breaks. OneTrust or Cookiebot as CMP.

  4. 04

    Blended measurement.

    Northbeam, Triple Whale, or Polar sitting above platform pixels. MTA plus incrementality. The number we actually run the business on.

§ 06 · Amazon as defensive moat

Amazon is not a channel. It is a moat.

Every wellness brand that grows past $3M ARR discovers counterfeits on Amazon under their name. The fix is defensive operation: enrol Brand Registry, run Transparency, build A+ content, match subscription with DTC cadence. DTC stays the flagship; Amazon protects the brand name.

op 01

Brand Registry + Transparency.

Enrol. Apply Transparency codes to packaging. Amazon verifies every unit. Counterfeits cannot list under your brand.

op 02

A+ content + Brand Story.

Own the above-the-fold on every listing. Ingredient spotlight, dose logic, founder story. Conversion rises; search rank follows.

op 03

Subscribe and Save match.

Amazon's Subscribe and Save cadence matches your DTC cadence. Buyers never see a conflicting cycle length.

op 04

Catalog sync from Shopify.

Shopify is source. Ingredients, dose, claim IDs sync to Amazon. One edit, both surfaces updated. No drift.

§ 07 · the Evidence Method

Six layers, one operating model.

Claim library. DSHEA surface logic. Evidence-first PDP. Subscription retention. Amazon parallel. Attribution stack. Built in this order because skipping a layer exposes the one above it.

  1. L1

    Claim library.

    Every marketing claim maps to a citation ID. Citations stored centrally, version-controlled, queryable in one URL.

  2. L2

    DSHEA surface logic.

    Structure-function statement plus mandatory disclaimer render from theme template. Prop 65, EU novel food, UK MHRA flags drive geolocation surfaces.

  3. L3

    Evidence-first PDP.

    Dose, bioavailability, ingredient provenance above the fold. Outcome-filtered reviews. Expandable ingredient panel. Aspirational below.

  4. L4

    Subscription retention.

    Dose-tuned cadence per SKU. Skip, swap, pause. Membership tier above discount baseline. 2nd-order CAC as the metric.

  5. L5

    Amazon parallel.

    Defensive listing. Brand Registry. Transparency. A+ content. Subscribe and Save matched to DTC cadence. Catalog sync from Shopify.

  6. L6

    Attribution stack.

    Server-side, CAPI, consent-mode v2, blended measurement. Recovers 80-92% of what platform pixels lose on long conversion windows.

§ 08 · the 2026 wellness stack

Six picks, opinionated.

Our 2026-Q2 default.

01 · platform

Shopify Plus.

Subscription complexity, Amazon parallel, international surfaces. Checkout Extensibility for regulatory gates.

02 · subscription

ReCharge.

Scale default. Deep Klaviyo integration. Dose-tuned cadence metafields. Skip-before-ship controls.

03 · email + SMS

Klaviyo + Attentive.

Seven retention flows tied to cycle timing: welcome, cart, post-purchase, replenishment, skip, win-back, VIP.

04 · reviews

Okendo.

Outcome-attribute filtering (sleep, energy, digestion). Syndicates to Google Shopping and Amazon.

05 · support

Gorgias.

Macros for wellness tickets: adverse event intake, subscription adjust, practitioner verification, lot questions.

06 · attribution

Northbeam.

Blended measurement above platform pixels. MTA plus incrementality. The honest number the business runs on.

§ 09 · the fit check

We turn down more wellness projects than we take.

Wellness has the highest regulatory exposure of any DTC category. The wrong engagement costs both sides. Here is our filter.

we're right for you if
  • $50K+ per month revenue, trending up
  • 50%+ contribution margin (supplement margins run high)
  • Willing to invest in claim library from day one
  • On Shopify or Shopify Plus (or willing to move)
  • Real substantiation files for every PDP claim
  • Founder committed to evidence-first positioning
we're wrong for you if
  • ×Unsubstantiated claims you refuse to remove
  • ×Dropship supplement catalogs with no first-party QC
  • ×Disease-treatment claims on non-prescription products
  • ×Single-SKU brand still finding audience
  • ×Rebrand-only engagement wanted
  • ×Treats agency as task-taker, not partner
§ 10 · four markets, four compliance regimes

The US playbook breaks in London and Sydney.

DSHEA applies only in the US. EU novel food, UK MHRA supplement notifications, Australia TGA listings each treat wellness differently. Claims allowed in one market are banned in another. We render the right surface for the right geography.

US

DSHEA.

Structure-function + disclaimer. FDA registration for facilities. Prop 65 for California.

UK

MHRA + FSA.

Medicines boundary. Health claim register. Specific wording permitted.

EU

EFSA novel food.

Health claim register (strict). Novel food authorisation for new ingredients. Country-specific labelling.

AU

TGA listed.

Listed medicines register for most supplements. AUST L number required on packaging and PDP.

§ 13 · questions

Eight answers.

What does a wellness ecommerce agency actually do?

A wellness ecommerce agency builds and runs the operating stack for a supplement, functional, or nutraceutical brand selling direct to consumer. That means Shopify or Shopify Plus storefront engineering, evidence-first product page design with claim-to-citation scaffolding, DSHEA structure-function statement rendering, FDA and FTC claim compliance workflows, subscription architecture tuned to dose and pack size, Amazon parallel-channel operations, Klaviyo and Attentive retention flows, and attribution stacks that handle wellness-specific long conversion windows.

What is the Evidence Method?

Our six-layer operating model for DTC wellness brands. Claim library as a data structure mapping every marketing claim to a citation. DSHEA surface logic rendering mandatory statements on every supplement PDP. Evidence-first PDP template with ingredient, dose, and study references above the fold. Subscription retention with dose-tuned cadence. Amazon parallel-channel operations. Attribution stack that handles long conversion windows. Six layers, bottom-up, because a claim without evidence is a legal exposure, not a marketing asset.

How much does a wellness ecommerce agency cost?

Pricing is scoped to engagement shape. Wellness brand audit: 2 weeks. Evidence Method build on Shopify Plus: 10-14 weeks. Subscription retention engagement: 6-8 weeks. Full wellness partnership: 12 months with a dedicated pod. Book a 30-minute call and we send a scoped quote within 48 hours. Scope moves price, not the conversation.

Do you handle DSHEA and FDA claim compliance for supplement brands?

Yes. DSHEA, the Dietary Supplement Health and Education Act, allows structure-function claims on supplements only when accompanied by the mandatory FDA disclaimer that the statements have not been evaluated by the FDA. Our Shopify build renders that disclaimer from a template, stores every claim as a structured metafield linked to its substantiation citation, and surfaces required warnings where applicable. We also handle California Prop 65, EU novel food rules, and UK MHRA boundaries for international catalogs. We are engineers and designers, not regulatory counsel; we build the workflow and your attorneys sign off.

How do we handle claim substantiation at scale as the catalog grows?

Claim substantiation is where most wellness brands break around the $5M ARR mark. The fix is architectural: every marketing claim on the PDP carries a machine-readable citation ID that maps to a substantiation file (clinical study, ingredient monograph, or regulatory precedent) stored in a shared drive or compliance database. When a retailer, FTC, or Amazon team asks for backup, the answer is a URL, not a fire drill. Our build includes the claim library, the PDP rendering logic, and the internal review workflow so new claims cannot ship to production without a cited source attached.

How do subscription cadences work for supplements versus skincare?

Supplement cadence is dose-driven, not billing-driven. A 60-capsule bottle at two per day is a 30-day supply; shipping every 30 days is in phase. A 120-capsule bottle at same dose is 60 days; shipping every 30 days doubles up and drives churn. We read dose and pack size from metafields and set default cadence per SKU. Skip, swap, pause without cancel, and membership tier above the 15 percent subscribe-and-save baseline. Target churn under 4 percent monthly and skip rate under 20 percent.

How does attribution work for wellness brands with long conversion windows?

Wellness buyers take 14 to 45 days to buy after first touch, much longer than fashion or beauty. Platform pixels miss most of that because of iOS 18 ITP and consent loss. We build a four-layer attribution stack: server-side tracking via GTM Server Side or Stape, Meta CAPI and Google Enhanced Conversions, consent-mode v2 for EU and UK, and blended measurement in Northbeam or Triple Whale. Together they recover 80 to 92 percent of what the pixels lost and make long-window attribution legible.

Can you manage Amazon parallel operations alongside DTC?

Yes. Amazon is defensive for wellness brands; you do not ignore it and hand the brand name to counterfeits. We run product data syndication from Shopify out to Amazon Vendor or Seller catalogs, enrol in Brand Registry and Transparency for counterfeit protection, build A+ content and Brand Story, and configure Subscribe and Save with cadence matched to your DTC subscription program. DTC remains the flagship with the margin; Amazon is the moat around the brand name.
