How these guides work
Each guide sticks to what you can check yourself: what the label says, what the different forms are, how to compare doses and prices fairly, and where to look a product up on the official register. We don't tell you what a supplement will do for you — that's a conversation for your pharmacist, doctor or practitioner, who knows your health and your other medicines.
In Australia, most vitamin and mineral supplements are listed medicines and carry an AUST L number, while protein powders and many sports powders are sold as foods and carry a nutrition information panel instead. Knowing which one you're holding is the first step in reading the label — the how to check a supplement guide explains both.
