About Us
We source the world's best science so you don't have to cross borders to find it. OptimOZ was born out of personal frustration: the supplements that actually work — the ones researchers, physicians, and serious biohackers use — were not available in Australia.
Started by customers, not a corporation
We were looking for same things you probably are: a way to think more clearly, perform better, and stay healthy longer. The products that delivered results — the Bulletproof Coffee he'd discovered, the nootropics and smart supplements gaining traction overseas — simply weren't available in Australia at a reasonable price or with reliable delivery.
A chance meeting with Dave Asprey, creator of Bulletproof Coffee, gave the store its first import partnership. But from the beginning, the mission was broader than any single brand: to bring the world's most rigorously vetted wellness products to Australian doorsteps.
Twelve years later, OptimOZ is Australia's destination for biohackers, people known for seeking out the cutting edge. The keto roots are still here. The biohacking philosophy never left. But the range, like the science, has changed.
How we think
We don't stock 10,000 products. We stock the ones we'd actually put in our own protocols. Every brand on OptimOZ went through the same filter.
Science before hype
If a compound is going viral on TikTok, we look at the peer-reviewed research first. Ideally human RCTs. Always mechanisms. Never just testimonials.
Transparency from source to shelf
We ask our suppliers where ingredients come from, how products are tested, and what's actually in each capsule. If they can't answer, they don't make the range.
Worth the premium
Everything here costs more than a pharmacy multivitamin. It should. We explain why — bioavailability, delivery formats, clinical dosing — so you can decide for yourself.
Longevity over quick fixes
We're building ranges around healthspan, not trends. Compounds that support cellular energy, gut resilience, cognitive reserve, and muscle integrity as you age.
