How to read a supplement label

A plain-English walkthrough of every part of an Australian supplement label — AUST L number, active ingredients, doses and excipients.

What an AUST L number means (and what it doesn't)

What an AUST L number confirms about a listed medicine, what it doesn't confirm, and how to look it up on the ARTG.

AUST L vs AUST R: the difference

Listed (AUST L) and registered (AUST R) medicines are assessed to different standards. Here is what differs.

Proprietary blends explained

What a proprietary blend is, why it hides individual ingredient amounts, and how to spot one on a label.

Elemental vs salt-form dosing

Why labels list compound forms like magnesium oxide, how the elemental amount is different, and how to convert.
