Common questions about how OptiLabs works: testing, supplements, clinician review, returns and timing.
Should I take prebiotics with probiotics?
A synbiotic approach — combining probiotics with prebiotics — is generally more effective than either alone. Prebiotics provide fuel for the bacteria you are introducing or maintaining.
Are the supplements safe?
All carry an AUST L designation from the TGA. Every order is reviewed by a clinician before dispatch.
Do I need a referral?
No. All tests are available to order directly. Our lab partner is NATA and RCPA accredited, operating as a direct-access pathology service.
