Australian Supplement Regulations: What the TGA Requires

The Two Regulators: TGA and FSANZ

Format and claims decide which body owns the product. Not ingredients.

The Therapeutic Goods Administration (TGA)^[2] operates under the Therapeutic Goods Act 1989. It regulates anything making therapeutic claims, meaning claims about treating or preventing a condition, supporting a body system, or managing symptoms. Tablet, capsule, or pill form? TGA jurisdiction applies even if the active ingredient is a humble vitamin C.

Food Standards Australia New Zealand (FSANZ)^[3] regulates food, and most powder-format supplements sit here. Protein powders and plain creatine monohydrate are food products under the Food Standards Code, provided they stay quiet on therapeutic language. The Formulated Supplementary Sports Foods standard (Food Standards Code Standard 2.9.4) sets permitted ingredients, compositional limits, and labelling rules for the sports-food subset. Nutrient reference values that underpin labelling tolerances come from the Australian Government's National Health and Medical Research Council^[5], not from FSANZ itself. Our verdict: this is the standard most Australian protein tubs are actually built around, even though the marketing rarely says so.

A November 2023 change shifted sports supplements in tablet, capsule, or pill form making performance or exercise claims into TGA jurisdiction. Powder and liquid formats meeting Food Standards Code requirements were carved out and remain food-regulated. The carve-out matters. We've watched brands restructure entire ranges around it.

Listed Medicines (AUST L) vs Registered Medicines (AUST R)

Inside the TGA framework there are two tiers, and they are not equivalent.

Listed medicines (AUST L) are low-risk products. The manufacturer self-assesses compliance against an approved-ingredient list and safety standards. The TGA then audits a sample. Vitamins, minerals, and most sports supplements that make it onto the ARTG^[1] live here. An AUST L number tells you the product is on the register. It does not tell you the TGA has verified the formula works. We read AUST L numbers as a hygiene check, nothing more.

Registered medicines (AUST R) require pre-market TGA evaluation of safety and efficacy. The bar is materially higher. Manufacturers must submit clinical evidence. Most prescription medicines and many over-the-counter analgesics sit here. Almost no sports supplements do.

This split sets the ceiling on what ARTG listing actually guarantees. For most supplements, it confirms a self-declaration that the product uses approved ingredients and the label complies with the rules. That's it. No independent body has confirmed the product does what it says.

Protein Powders and Creatine Under Australian Law

Open a tub of unflavoured whey or scoop of plain creatine monohydrate at any Australian retailer, and you are holding a food product under FSANZ, not a therapeutic good. These sit under the Food Standards Code^[3], with rules on labelling accuracy, additive safety, and the nutrition information panel. They are not bound by TGA therapeutic-claim restrictions.

The most useful FSANZ rule for our purposes: the nutrition information panel has to reflect what's actually in the tub. Protein per 100g, serving size, macro split. These figures are required to be accurate within defined tolerances. That's real consumer protection for the numbers we benchmark every day. When a 30g serve claims 25g of protein, the label is legally required to be a real number, not a marketing one.

Pre-workout occupies messier territory. Powder-form, claim-light products usually sit under FSANZ. Anything making therapeutic claims, or anything sold as capsules, typically requires TGA listing^[2]. Our rule of thumb: if the label says "accelerates recovery" or "boosts immunity", expect TGA jurisdiction. If it says "performance formula" and stays vague, expect FSANZ food regulation.

Advertising Rules: What Companies Can and Cannot Claim

The TGA controls therapeutic claims tightly. A Listed medicine can only advertise indications that match its ARTG entry. Words like "treats", "cures", or "prevents" a disease are reserved for Registered medicines, which is a much harder badge to earn.

This is why supplement copy is so vague. "Supports muscle recovery." "Promotes wellbeing." "Helps maintain healthy levels." These soft constructions are deliberately within the bounds of what a Listed medicine can assert without clinical evidence. Specific efficacy claims require AUST R, and almost nobody is willing to pay for that pathway. Our take: this softness is a feature of the regime, not a marketing accident.

FSANZ-regulated food products run on a separate set of rules covering nutrition content claims and health claims. General-level health claims (linking a nutrient to a health outcome) are permitted when backed by standards in the Food Standards Code. High-level health claims (linking food to a serious disease) need specific approval and rarely appear on a protein tub.

Banned Substances and Contamination Risk

Australia follows the WADA (World Anti-Doping Agency) prohibited list for substances banned in competitive sport. Several ingredients still turn up in supplements: SARMs (selective androgen receptor modulators), peptide hormones, and stimulants like DMAA (1,3-dimethylamylamine).

DMAA in particular has been found in some pre-workout and fat-burner products sold in Australia despite being prohibited. The TGA^[2] has issued recalls and warning letters over undeclared DMAA. Contamination, whether from deliberate spiking or sloppy manufacturing, is the main reason third-party testing matters for any tested athlete. We've watched compliant-looking labels turn up on products that later got pulled. The label is not the test.

SARMs are scheduled substances and are not permitted for sale in Australia. They still appear in the local market via grey-channel imports. If you compete in any tested sport, the only defensible approach is sticking to products certified by a recognised third-party testing program. The Australian Institute of Sport's ABCD framework^[4] is the go-to reference for which ingredients are evidence-backed (Group A) versus high-risk for tested athletes (Group D).

Importing supplements for personal use is legal up to a three-month supply. Commercial import requires TGA approval. Anything containing prohibited substances can be seized at the border, even if it's legal in the country of origin.

Third-Party Testing: What to Look For

For competitive athletes, or anyone seriously worried about contamination, third-party certification adds a layer that TGA listing alone doesn't provide. Locally, the relevant body is HASTA (Human and Supplement Testing Australia), which tests products against the WADA list and certifies batches that pass.

Overseas, the heavyweights are Informed Sport and NSF Certified for Sport. A logo on the tub means the specific batch was tested for prohibited-substance contamination. Worth flagging: that is not the same as verifying the protein content matches the label. It's a doping-risk check first and foremost.

Reputable brands also publish Certificates of Analysis (CoA) from independent labs for each batch. A CoA confirms label-claim accuracy: protein content, heavy metals, undeclared ingredients. If a brand won't supply a CoA on request, we treat that as a serious quality red flag. The good operators send them without being asked twice.

How to Check if a Supplement Is TGA Approved

If a supplement is a therapeutic good, you can confirm its listing in three steps:

• Find the AUST L or AUST R number on the label: therapeutic goods are required to display one.
• Open the TGA's public Australian Register of Therapeutic Goods search^[1] at tga.gov.au/resources/artg.
• Search by that ARTG number, the product name, or the sponsor, and confirm the registered entry matches the product you're buying.

A product displaying an ARTG number that isn't in the register is a regulatory violation. Report it to the TGA.

Food-classified supplements, which covers most protein powders and plain creatine, have no ARTG entry by design. There is no public FSANZ register equivalent. Food compliance is enforced by state and territory food safety agencies via market surveillance, not pre-market approval. A protein powder with no ARTG number on the tub is normal. Not a problem.

What This Means for Everyday Buyers

For most people buying protein, creatine, and pre-workout from reputable Australian retailers, the regime provides a reasonable safety floor. Label macros are legally required to be accurate. Approved-ingredient lists keep the worst substances out of mainstream retail. Advertising rules clamp down on the most egregious efficacy claims. Our verdict: it's a sensible baseline, well below world-best, well above unregulated.

What it doesn't guarantee is that any given supplement works as marketed, that doses match published evidence, or that every product is clean of contamination. For real assurance, combine three things: an established brand we can find recalls and CoAs for, a third-party testing mark where contamination matters, and a sceptical read of the label. That's the combination we use ourselves.
