Supplement Websites and the TGA Line You Cannot Cross

Two Australian brands sell what is functionally the same magnesium capsule, from the same contract facility. One product page opens with "clinically proven to end restless nights and take the edge off everyday anxiety." The other says "helps maintain healthy sleep patterns" and puts the AUST L number under the buy button. One of those pages is operating inside its listing. The other is a complaint file waiting to be opened.

Supplements are the most tightly constrained e-commerce category in Australia, and the constraint sits on the words rather than the product. If your goods are in the Australian Register of Therapeutic Goods, the Therapeutic Goods Administration regulates what your website may say about them — and "website" means every surface. Product copy. Collection names. The symptom quiz. Meta descriptions. Customer reviews. Your affiliate's Instagram story.

Our position: claim compliance is an architecture problem, not a copywriting problem. Most brands treat it as a legal review that happens once, before launch. Then a marketer ships a landing page through the CMS eight weeks later and the review never happens again. The sites still compliant three years in are the ones where the build makes the non-compliant version hard to produce.

Everything on the site counts as advertising

An advertisement, under the therapeutic goods framework, is essentially anything intended to promote the use or supply of the goods. That swallows more of a website than founders expect: the product description, the collection page it sits in, the abandoned-cart email, the "education" article linking to the product, and the creator video nobody signed off line by line.

The TGA handles advertising complaints directly, and anyone can lodge one. A meaningful share comes from competitors who have read the code more carefully than you have and noticed your homepage promising something theirs legally cannot. The enforcement trigger is rarely a regulator browsing your store. It's a rival with a screenshot.

Which is why the surfaces nobody proofreads matter. Collection and navigation labels are the biggest: a "shop by concern" menu listing Sleep, Stress, Immunity and Gut applies a therapeutic claim to every product in each collection, published by whoever set up the merchandising. Filter facets do the same, and so do bundle names — "The Recovery Stack" asserts something. So does the quiz that asks about sleep and stress, then recommends a product. Quizzes convert well, which is why they need the tightest claim governance on the site.

It continues past the visible page: meta titles and descriptions are advertising and they're what Google displays, structured data pushes claims and star ratings into search results, and email flows sit in a tool outside the CMS entirely. Running our free site audit shows what's currently indexed — it can't assess claims, but it surfaces the public pages you'd forgotten, where unreviewed copy hides.

What your listing actually permits

Which rules apply depends on which regulatory bucket the product sits in, and plenty of brands sell across two without realising.

Sports products make the split messy. The TGA declared certain sports supplements in medicine-like dosage forms — tablets, capsules, pills — to be therapeutic goods rather than foods, and the transition period has closed. So a brand selling a protein powder and a pre-workout capsule runs a food and a medicine on one storefront, with different mandatory statements on each. If the product template treats them identically, one is wrong.

Two rules catch supplement copy constantly. Representations referring to serious diseases and conditions are restricted and need approval before use. And implying goods are endorsed or approved by a government agency is prohibited, which makes "TGA approved" on a listed-medicine page a breach in itself. A listed medicine is included in a register. It is not approved in the sense a shopper reads that word.

Mandatory statements matter too. Medicine advertisements generally carry words to the effect of "always read the label and follow the directions for use," and vitamin advertisements a further statement about supplements not replacing a balanced diet. Pull the current wording from tga.gov.au, not from a competitor. The design consequence is the part people miss: those statements must be legible and reasonably prominent, and 10px grey in the footer is neither.

Why you cannot clone the American brand's copy

Almost every supplement founder has a US brand they want to sound like, and that instinct is the fastest route to a breach. American copy runs on structure-function claims paired with the familiar disclaimer about statements not being evaluated by the FDA, which buys those brands real latitude. Here it buys nothing — it's the regulatory equivalent of a foreign power adaptor, correct shape somewhere else, no use in this socket.

Three American habits break here. Naming the conditions a product addresses, which runs into restricted representations. Citing a study as proof the product works, when "clinically proven" sets up an efficacy expectation your listing may not support. And practitioner endorsement — the doctor or naturopath recommending the formula — which is prohibited when advertising therapeutic goods to the public, however genuine the practitioner.

Weight-management copy deserves its own warning: the code carries specific requirements there, and the transformation-photo playbook sits well outside them. Australian Consumer Law applies on top of all of it, so even a product regulated purely as food is exposed to the ACCC on misleading conduct. No bucket is a free-for-all.

Reviews, creators, and the testimonial trap

Testimonials catch supplement brands most often, because the mechanism is counter-intuitive: a customer wrote it, but you published it.

A review on your product page saying the product cured a condition is, on your page, a representation you have made. Nobody wins a complaint by arguing the customer typed it. Most review apps publish automatically by default, and that default is the actual risk. Set moderation to hold-for-approval, add a blocked-term list covering condition names and cure language, and have a human read every review. With aggregate rating schema on, those reviews travel into your search snippet too.

The code also prohibits testimonials from people connected to the business — those involved in producing, marketing or supplying the goods, plus employees, agents and relatives. Founder-family reviews, staff reviews and the ambassador who quietly holds equity all fail that test. Practitioner endorsements are out separately.

Creator and affiliate content is the same problem with less control, because you are responsible for what they say. Brief, contract and approval loop all have to reference the same claim set the site uses. And an Instagram hashtag widget pulling arbitrary user posts onto product pages is an uncontrolled claim feed embedded in your storefront.

Which puts supplement brands in an odd spot: most Australian businesses badly under-use social proof — we've written about what makes testimonials work here — while supplement brands have to govern it harder than anyone. Steer reviews toward what's legal and still persuasive: taste, mixability, capsule size, delivery speed, how easy it was to pause a subscription.

The trust signals you are allowed to use

Strip out the claims and more is left than founders expect, because the constraint pushes you toward the signals that build real trust anyway. Show the AUST L number on the product page, not only the label. Name the manufacturer, and say plainly if it's a TGA-licensed Australian facility. Publish batch testing findable by batch number, not as a PDF nobody links to. If competitive athletes buy from you, third-party banned-substance certification is decisive, and Sport Integrity Australia is the reference point they use.

Ingredient transparency does heavy lifting too: every active and excipient, with the real dose per serve rather than a proprietary blend. Shoppers who compare doses are your best customers.

Subscription mechanics belong on that list, because retention is the business model here and trust is what makes someone accept a recurring charge. Skip, pause, change frequency and cancel all need to be self-service — the retention patterns that work for consumables transfer almost directly. Whether you run subscriptions through a platform app or natively on Stripe decides how much control you have there, and control matters more in this category because the compliance surface extends into every renewal email.

Building it so compliance survives contact with marketing

The failure mode is always the same. The site launches compliant and then drifts, because the CMS treats claim copy as free text, and free text is where breaches live.

Make benefit copy a controlled vocabulary. Each product gets its indication selected from a claim library that maps to your listing, rather than typed into an open field. If a marketer wants a new claim, the friction is deliberate and it lands in front of someone who can approve it.

Attach a product-type field to every SKU — food or medicine — and let the template render the right mandatory statements automatically, at readable size. Put a moderation queue in front of reviews and a term filter behind it. Keep dated page version history, so a complaint can be answered with exactly what the page said and when. Route new landing pages through staging with an approval step.

If you sell into two markets, the claim set has to vary at the template level: the Australian page and the American page cannot share a copy field. None of this is exotic — it's ordinary e-commerce architecture with the claim layer treated as part of the data model rather than an afterthought.

FAQ

Can I put customer reviews on a supplement website in Australia?

Yes, with moderation. Reviews you publish on your own site are content you control, so a review referring to treating or curing a condition becomes a representation you have made. Hold reviews for approval, filter for condition and cure language, and exclude testimonials from anyone connected to the business — staff, agents, relatives, and people involved in producing or supplying the goods.

Reviews about taste, texture, delivery and subscription flexibility carry no therapeutic claim and convert perfectly well.

Do I need TGA approval before my supplement website goes live?

There is no approval process for a website itself. Your obligation is that the advertising complies with the Therapeutic Goods Advertising Code and stays consistent with your ARTG entry. Restricted representations — those referring to serious diseases or conditions — do require approval before use. You also cannot advertise goods not yet in the ARTG, which rules out a "coming soon" page for a product whose listing is pending.

Can I say my supplement is TGA approved?

No. Implying government endorsement or approval is prohibited, and for a listed medicine it is also inaccurate: AUST L goods are assessed for safety and quality, not efficacy. Display the AUST L number instead. If your product holds an assessed listing, you may use the mark that comes with it — the one case where a TGA-assessment claim is available.

Can I use the same product copy in Australia and the United States?

No. Australian claims for a listed medicine must come from the permissible indications determination, and the FDA disclaimer that licenses broader US copy has no effect here. Make claim copy a market-specific field, and never let geo-detection serve US copy to an Australian shopper.

Where to start this week

Read your own site the way a regulator would, starting with the surfaces you didn't write. The nav labels. The collection names. The quiz results. The last four reviews published. The meta description Google is showing. That takes an afternoon and locates most of the problem. Then decide whether your platform can hold the fix — because if claims live in free-text fields and reviews publish themselves, careful copywriting won't keep the site compliant past the next marketing hire.

Our custom builds start at $8,000 AUD, and for a supplement brand a real share of that goes into claim architecture: the controlled vocabulary, the moderation layer, the product-type logic driving mandatory statements. Unglamorous work that never appears in a portfolio shot, and the difference between a store that can move fast and one that can only move carefully.
