Is Vitamin B12 legal in Australia?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Yes. Vitamin B12 is an approved medicine in Australia. Its legal category is "Medicine and supplement". The approval covers the use on its label. It is given out on prescription, not sold over the counter. Products labeled "research use only" are not covered by that approval, and that label does not make them legal to use in people. On the evidence, 2 completed human trials are cited on its profile.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
TGA has approved Vitamin B12 for at least one use named on its label. So a proper pharmacy-grade product exists in Australia, and pharmacies hand it out on prescription.
- 02
Approval covers only the uses named on the label. Any other use is a prescriber's call. The approval itself does not cover it.
- 03
Unlicensed vials sold online, including those labeled "research use only", are not the approved product. The approval does not cover them.
What Vitamin B12 is
An essential vitamin given as a shot for a shortage. Wellness clinics offer it for energy, but it helps little if your levels are normal.
Vitamin B12 is a nutrient you must get from food. Your body needs it to make red blood cells, keep nerves healthy and make DNA.
How it works: It helps the enzymes that make red blood cells, keep nerves healthy and build DNA.
Approval history: Approved for deficiency; also sold as a supplement
How TGA treats this kind of product
Registers or lists medicines and health products on the ARTG, its official register. It also sorts substances into schedules in the Poisons Standard. Many peptides are Schedule 4 (prescription only). So having them without a prescription, or importing them for yourself, is restricted. That is true even when no product is registered.
The legal category above is how The Longevity Archive reads Therapeutic Goods Administration listings for Vitamin B12 on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.
Vitamin B12 in sport and the military
Whether Vitamin B12 is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Australia. Before you compete or get tested, look up Vitamin B12 by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.
