Effective weight loss supplements and management options available in Australia range from over-the-counter complementary medicines to prescription-only treatments.

Regulated by the Therapeutic Goods Administration (TGA) with an AUST L number, these options support a calorie-controlled diet and exercise:

- Protein Powders (Whey Protein Isolate, Casein, or Plant-based): Help manage appetite, support satiety, and preserve lean muscle mass during a calorie deficit. Popular local options include EHP Labs OxyWhey and Body Science Shred Protein. - Fibre Supplements (e.g., Glucomannan, Psyllium): Increase feelings of fullness, curb hunger, and help stabilise blood sugar spikes after meals. - Thermogenic Fat Burners & L-Carnitine: Products like EHP Labs OxyShred, ONEST Hyperburn, and various carnitine formulas aim to boost energy and metabolism, though evidence shows their direct fat-loss effects are modest. - Lipid or Fat Blockers: Over-the-counter products available through pharmacies and retailers like Priceline Australia and Supplement Mart Australia assist with specific metabolic or digestive targets.

### Prescription Weight Loss Medicines For medically supervised management, Australian doctors may prescribe targeted treatments reviewed by Healthdirect Australia:

- GLP-1 and GIP/GLP-1 Receptor Agonists (e.g., Saxenda, Wegovy, Ozempic, Mounjaro/Tirzepatide): Mimic gut hormones to regulate appetite and blood glucose, showing significant clinical weight reduction in trials. - Appetite Suppressants (e.g., Phentermine / Duromine): Central nervous system stimulants used short-term to reduce hunger. - Fat Absorption Inhibitors (e.g., Orlistat / Xenical): Reduces the amount of dietary fat absorbed by the intestines.

If you mean a fat-burning supplement you can buy in Australia, there isn't a supplement with strong evidence for producing large amounts of fat loss. The TGA specifically warns that many weight-loss supplements have limited evidence for sustained weight loss. Therapeutic Goods Administration (TGA) Therapeutic Goods Administration (TGA)

For a supplement, I'd focus on known ingredients rather than a “hardcore” fat burner. Caffeine has the strongest evidence among common supplement ingredients, although its effect on actual fat loss is modest. The AIS classifies caffeine as a Group A performance supplement.

### Products currently available in Australia

- EHP Labs OxyShred - $79.95 (Australian Muscle + others) - Onest Hyperburn - $59.96 (Australian Sports Nutrition + others) - Bulk Nutrients AM Burner - $33.00 (Bulk Nutrients) - Musashi Fat Metaboliser with Carnitine - $24.99 (Priceline + others)

My practical take: don't choose based on the biggest “thermogenic” claim. Check the actual caffeine dose and full ingredient list. The AIS specifically cautions that fat-loss products can contain large or poorly disclosed caffeine doses and may contain banned/contaminating substances.

Also avoid products containing DMAA, DMBA, ephedrine or high-risk stimulant blends; the AIS places these in its Group D category. Australian Sports Commission

If you tell me your age, sex, weight, height, and whether you want stimulant or stimulant-free, I can narrow it down to the most sensible options available in Australia.
