Supplement Copywriter in Australia

Amisha Sharma is a supplement copywriter in Australia and an ISB alumna at Commas & Chaos. She writes product and website copy to the permitted indications for listed medicines and to the Therapeutic Goods Advertising Code 2021. In April 2026 the TGA issued 4 infringement notices totalling $79,200 to a supplement brand over how it described a vitamin and an ingredient. Every page she writes is checked 226 ways before it ships.

01

01The difference

Same product. Two ways to write it.

✗ What most supplement brands write

"Clinically proven to reverse cellular ageing, ease anxiety and protect against disease. The strongest formula in Australia."

Three offences in one sentence. Mental illness is a prohibited representation, so it cannot be used at all. Protecting against disease is a restricted representation needing TGA permission. Strongest in Australia is a superiority claim that has to be substantiated under the Australian Consumer Law.

vs

✓ What I write

"Magnesium to support muscle function and general wellbeing. What is in it, why the form matters, how much per serve, and who it suits."

Legal, and it sells harder. Buyers in this category read labels. Specifics about form, dose and evidence beat a vague miracle claim with every customer worth keeping.

Compliant copy has a reputation for being boring. That is a writing problem, not a compliance one. I fix the writing.

Fined for describing a vitamin

Supplement founders think the risk is the ingredient. It is the sentence.

In April 2026 the TGA issued 4 infringement notices totalling $79,200 to a supplement company over the alleged unlawful advertising of products containing nicotinamide mononucleotide and vitamin D3 for the treatment of serious medical conditions. The formula was not the problem. The words on the page were. If your product copy names a condition, promises protection, or uses a paid creator's personal story, it is at risk. Check in 60 seconds, whether your site is live or still being written.

Four jobs. One writer.

delivered pages flagged by a regulator

Written to the permitted indications, not around them.

Listed medicines may only carry indications from the permitted indications list. If your claim is not on that list, no evidence file makes it available. Add the prohibited and restricted representation rules and most supplement copy in Australia is already over the line. I write inside the list and make it sell. No delivered work of mine has been flagged by a regulator to date.

↗

Built to get found, not buried.

I structure your pages so Google and AI search can understand them. That gives you a real shot at showing up when someone searches for a supplement like yours, by ingredient or by benefit.

✎

Premium, so you stop competing on price.

Copy that sounds like a formulation team, not a dropshipper. It attracts repeat buyers who care about form and dose, and it makes a higher price feel obvious rather than cheeky.

My eyes on every word. Every time.

You are never a ticket number in an agency queue. Your pages are never handed to a junior or a content mill. You brief me, I write, and the person answering your email is the person who wrote your homepage. That is why the quality holds, from page one to page fifty.

05Who writes your copy

Amisha Sharma.

I'm Amisha Sharma, a compliance-first copywriter for regulated Australian brands, supplements included. I am an ISB alumna, agency trained on Australian accounts. No delivered work of mine has been flagged by a regulator to date. My job is copy that stays inside the rules, ranks on Google, gets quoted by AI, and still sounds like a human wrote it. Every page runs through my 226-point GhostRank audit before it ships. Supplements are the lane where the best-performing ad and the unlawful one are usually the same sentence, so I write the version that does the work without the risk.

06The alternatives

Why not just hire any copywriter?

Because the copy that performs best in this category is usually the copy that gets fined. Here is the honest comparison.

✗

An SEO agency

Ranks you for condition keywords you are not allowed to claim. They know Google. They have never read the permitted indications list.

✗

A compliance lawyer

Keeps you legal and hands you copy no one reads. Safe and invisible is still invisible.

✗

A cheap freelancer

Copy full of borrowed claims from an overseas brand. Those claims are legal there and unlawful here.

✗

ChatGPT on its own

Fast, generic, no judgement. It will happily write helps fight disease, which is a restricted representation.

✓

A compliance-first copywriter

Compliant, ranks, quoted by AI, books repeat orders. I do all four. And I personally watch every word, so you always know who is writing: me. Every page passes the 226-point GhostRank check first.

07

07The rules, in plain English

What can an Australian supplement brand actually claim?

Short version: for a listed medicine, only what is on the permitted indications list, said without a prohibited or restricted representation. Here is how that plays out on a real product page.

✓ What you can say

Use an indication that appears on the permitted indications list.
Describe the ingredient, the form, the dose per serve and who it suits.
Explain your testing, sourcing and manufacturing standards accurately.
Publish genuine, unpaid customer reviews of a non-prescription product.
Include the mandatory information required in advertisements other than labels.

vs

✗ What you can't say

Refer to cancer, mental illness or other prohibited representations at all.
Claim to treat or prevent a serious disease without TGA permission.
Advertise a therapeutic good that is not included in the ARTG.
Use a paid or incentivised testimonial, including from an influencer.
Claim to be the strongest or the best without being able to prove it.

Why do supplement brands get fined for copy that reads normal?

Because the category's house style was imported from countries with different rules. In Australia, a listed medicine may only carry indications drawn from the permitted indications list. That is a closed list. If the indication is not on it, the product cannot carry it, regardless of how good the evidence is. Some claims, such as lowering blood pressure, are simply not available to listed medicines at all. On top of that sit two harder limits. Prohibited representations, which include references to cancer and to mental illness, cannot be used in any circumstances. Restricted representations, which refer to serious diseases, conditions or disorders, need TGA approval or permission before they can appear. Advertising a therapeutic good that is not in the ARTG is separately unlawful, and that catches a lot of products sold as food-adjacent wellness items.

The enforcement is real and it is recent. In April 2026 the TGA issued 4 infringement notices totalling $79,200 to Switch Nutrition Pty Ltd over the alleged unlawful advertising of therapeutic goods containing nicotinamide mononucleotide and vitamin D3 for the treatment of serious medical conditions. The bigger precedent came in April 2020, when ATP Science Pty Ltd was issued 24 infringement notices totalling $302,400 over alleged advertising of therapeutic goods not included in the ARTG, including prohibited representations relating to cancer and the treatment of mental health conditions, along with restricted representations. That company also entered an enforceable undertaking. In both cases the product was not the issue. The sentence was.

Then there is the channel most supplement brands actually sell through. The TGA updated its social media advertising guidance on 6 November 2025. Responsibility sits with whoever controls the account or platform, and that includes third-party comments on your own channels. Influencers promoting therapeutic goods are advertisers under the Act and carry the same obligations, and a manufacturer is responsible for what an influencer acting on its behalf posts. Paid or incentivised testimonials are not permitted, so a creator you pay cannot tell their personal story about using your product. They can act as an ambassador without claiming personal use, and genuine unpaid reviews remain available. Whether content counts as advertising depends on its overall effect, not on how it is labelled, so a post framed as education or personal experience can still be advertising. Underneath all of it, the Australian Consumer Law prohibits misleading or deceptive conduct, and the ACCC does not wait for the TGA. Start with the Therapeutic Goods Advertising Code 2021 and the social media guidance.

the unfair advantage

A tool no other copywriter has. Yours, on the house.

GhostRank is my proprietary 226-point audit. It checks how a page ranks on Google, how it reads to AI search, and where it breaks the advertising rules. Supplement brands pay $1,500 for this audit on its own. When you hire me, every page runs through it before it ships. You never pay for it.

A note from me

Dear founder,

You formulated something good. Then you found out the sentence that sells it is the one you are not allowed to write.

I understand the frustration. Every competitor on your feed seems to be claiming more than you are. Half of them are overseas brands under different rules. The other half have not been caught yet. Meanwhile your agency keeps sending back ad copy that would cost you $79,200 if the wrong person read it.

Here is what I have learned writing compliance checked copy. The claim was never doing the work you think it was. Buyers in this category are unusually literate. They read the label, compare the form, check the dose and look for who made it. A page that gives them that detail outsells a page that promises to reverse ageing, and it does not carry the risk.

The rules are strict and they are knowable. Permitted indications for listed medicines. No prohibited representations. No restricted representations without permission. No paid testimonials, including from the creator you just briefed. Nothing advertised that is not in the ARTG.

I write to those rules every day, and I hand back a note on why each claim is safe. No delivered work of mine has been flagged by a regulator to date. That is the quiet confidence I want to hand you.

So let me take the words off your plate. Every claim checked. Every page written to sell what you actually made.

You made the product. Let me handle the words.

09Questions

The ones supplement founders ask.

What are permitted indications, in plain English?+

They are the closed list of claims a listed medicine is allowed to carry. The claims come from the Therapeutic Goods (Permissible Indications) Determination. If the indication is not on the list, your product cannot carry it, no matter how strong your evidence file is. Some claims, such as lowering blood pressure, are not available to listed medicines at all. This is the rule that surprises founders most, because it is not an evidence test.

What happened to Switch Nutrition in April 2026?+

The TGA issued 4 infringement notices totalling $79,200 to Switch Nutrition Pty Ltd over the alleged unlawful advertising of therapeutic goods containing nicotinamide mononucleotide and vitamin D3 for the treatment of serious medical conditions. It was announced on 28 April 2026. The point worth taking from it is that the enforcement was about how the products were described, not about what was in them.

Has a bigger penalty been issued to a supplement brand?+

Yes. In April 2020 ATP Science Pty Ltd was issued 24 infringement notices totalling $302,400 over alleged advertising of therapeutic goods not included in the ARTG, including prohibited representations relating to cancer and the treatment of mental health conditions, along with restricted representations. The company also entered an enforceable undertaking with the TGA.

Can we use influencers and paid creators?+

Yes, but not for testimonials. Paid or incentivised testimonials are not permitted, so a creator you pay cannot tell their personal story about using your product. They can act as an ambassador and talk about the brand without claiming personal use. Genuine unpaid customer reviews of a non-prescription product remain available to you.

Who is responsible if an influencer says something unlawful?+

Usually both of you. Under the TGA's social media advertising guidance updated on 6 November 2025, influencers promoting therapeutic goods are advertisers under the Act with the same obligations as a business, and a manufacturer is responsible for what an influencer acting on its behalf posts. You are also responsible for third-party comments on channels you control, which means your own comment sections.

Can we mention anxiety, sleep or stress?+

Careful. Mental illness is a prohibited representation, so references to conditions such as anxiety or depression are not available at all. General wellbeing style claims may be available if they appear on the permitted indications list for your product. The safe method is to check the list first and write to it, rather than write the claim and hope it survives.

Is a disclaimer enough to fix a strong claim?+

No. Whether content is advertising, and whether a representation has been made, depends on the overall effect of the material rather than on how it is labelled. A disclaimer under a headline that promises to cure something does not undo the headline. This is also why content framed as education or personal experience can still be advertising.

Does the Australian Consumer Law apply on top of all this?+

Yes, and it is a separate exposure. The ACL prohibits misleading or deceptive conduct, and the ACCC enforces it independently of the TGA. Superiority claims such as the strongest formula in Australia, and comparisons with named competitors, are ACL problems even when they are not TGA problems.

Will compliant copy still convert on Meta and Google?+

Yes, and usually better. Ad platforms reject health claims aggressively, so the compliant version tends to survive review and keep spending while the aggressive version is stuck in appeals. On the page, specifics about form, dose, sourcing and testing convert better with the label-reading buyers who become repeat customers.

What does supplement copywriting cost?+

Prices are fixed and published. The GhostRank Audit is $1,500 for up to 20 pages, and every flag comes with a suggested compliant rewrite. Website copy packages are $2,490 for five pages and $4,390 for ten. Ongoing SEO is $2,000 a month on a six month minimum. There is no hourly billing and no surprise invoice.

Do you guarantee it's compliant?+

I write to the current Advertising Code and the permitted indications for your listing, and I add a short note on why each claim is safe. That note makes your next review fast and cheap. No writer can promise a regulator's final view. No delivered work of mine has been flagged by a regulator to date.

Supplement copy that sells inside the permitted indication.

Same product. Two ways to write it.
