How to Read a Supplement Label in Australia
How to read a supplement label in Australia — serving sizes, proprietary blends, TGA general claims and what AUST L numbers mean — so you buy smart.
Quick answer
To read a supplement label in Australia, check the serving size against the scoop, read the full ingredient list (watch for proprietary blends that hide doses), compare the nutrition panel per 100 g, and treat health claims as general — they're regulated by the TGA and don't mean a product treats disease. Look for third-party testing if you're a drug-tested athlete.
Supplement labels are designed to sell, not to inform. Learn to read the fine print and you'll spot good value — and marketing fluff — in seconds. Here's how, Australian-style.
1. Serving size vs scoop size
The headline numbers (e.g. "25 g protein") apply to the serving size listed, which isn't always one scoop. If the serve is two scoops, your tub holds half as many servings as you think. Always divide the price by the real number of servings.
2. The nutrition panel — compare per 100 g
Serving sizes vary between brands, so "per serve" numbers aren't comparable. The per 100 g column is the great equaliser — use it to compare protein content, sugar and calories fairly across any protein powder.
3. The ingredient list and "proprietary blends"
Ingredients are listed by weight, most first. Be wary of a proprietary blend: it lists several ingredients under one total, hiding how much of each you're getting. A product can name an impressive ingredient while including a tiny, useless dose. Favour labels that disclose each dose.
| Label phrase | What it really means |
|---|---|
| "Proprietary blend" | Individual doses hidden — could be under-dosed |
| "Contains added aminos" | May be cheap filler aminos boosting the protein figure |
| "Natural flavours" | Fine, but says nothing about sweeteners — read on |
| "Per serve" claims | Check the serve size before comparing brands |
4. Sweeteners and additives
Artificial sweeteners like sucralose are common and safe at normal intakes, but if you prefer to avoid them, check for them explicitly — our guide to sweeteners in protein explains the options. The same goes for thickeners and anti-caking agents, which are harmless but worth knowing.
5. TGA general claims — what's legal in Australia
In Australia, supplement claims are regulated by the Therapeutic Goods Administration (TGA). Most sports supplements carry general claims ("supports muscle recovery", "contributes to energy") rather than disease-treatment claims, which aren't permitted. Some listed products carry an AUST L number, indicating they're listed on the ARTG for safety and quality. A claim being "general" is normal and expected — it doesn't mean the product is weak.
6. Testing and certification
For drug-tested athletes, the ingredient list isn't enough — you want third-party batch testing. Learn what the seals actually prove in third-party testing explained and HASTA certification explained. For everyone else, testing is a nice signal of quality control.

Supplements support — not replace — a balanced diet and consistent training. Claims are general in nature; always read the label and follow directions for use. If you're pregnant, breastfeeding or managing a medical condition, check with your GP first.
