Direct answer

Omega-3 can be sold in Australia as a supplement or cosmetic ingredient, classified as "Available as a supplement / complementary medicine". That is not drug approval: TGA has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 5 human studies are cited on its profile.

What this means

  • 01

    Omega-3 can be sold in Australia as a supplement, food or cosmetic ingredient under the classification above, without drug approval.

  • 02

    Supplement status means TGA has not evaluated any health claim; manufacturers are responsible for safety and labeling, and quality varies by product.

  • 03

    Injectable or "research use only" versions are not supplements. That label does not make human use lawful, and injectables fall under medicines rules.

What Omega-3 is

Two large outcome trials reached opposite conclusions and the difference may be the placebo. Blood levels track strongly with living longer, supplements mostly do not, and the atrial fibrillation risk is real and dose-dependent.

Omega-3 is the most interesting evidence problem in this pillar because the literature contains a genuine, unresolved dispute rather than a simple null. One trial of 8,179 patients found a large reduction in cardiovascular events.

Mechanism: EPA and DHA incorporate into cell membrane phospholipids, displacing arachidonic acid and altering membrane fluidity and the substrate pool for eicosanoid synthesis. They are precursors to resolvins and protectins, which actively terminate inflammation rather than merely failing to promote it.

Regulatory history: Icosapent ethyl and omega-3-acid ethyl esters are FDA-approved prescription drugs for severe hypertriglyceridaemia, with icosapent ethyl carrying a cardiovascular risk reduction indication. Over-the-counter fish oil is a dietary supplement and is not approved to treat anything.

How TGA treats this kind of product

Registers or lists therapeutic goods on the ARTG and schedules substances in the Poisons Standard. Many peptides are Schedule 4 (prescription only), so possession without a prescription and personal importation are restricted even when no product is registered.

The classification above is the The Longevity Archive reading of Therapeutic Goods Administration listings for Omega-3 at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
