Australians are estimated to have irritable bowel syndrome
Gut Foundation Australia.
The gut conversation, actually investigated.
Explore gut health tests, digestive supplements and consultations in one place.
Your gut symptoms have a cause. It’s measurable.
Most IBS diagnoses describe a pattern, not a cause. SIBO, food sensitivities and dysbiosis are treatable when you know which one you’re dealing with.
OptiLabs uses functional reference ranges, calibrated to how well your body needs to perform, not just where clinical pathology begins.
