Spore-forming probiotic
Bacillus subtilis DE111
A clinically studied spore-forming probiotic that survives the acidic stomach environment and germinates in the small intestine, where it supports microbiome balance and digestive comfort.
Included
Fermentation-derived metabolites
Postbiotic fraction
Postbiotics are the bioactive by-products of microbial fermentation – short-chain fatty acids and other metabolites that directly signal gut immune and epithelial cells.
Included
Always read the label and follow directions for use. Vitamins and minerals can only be of assistance if dietary intake is inadequate. If symptoms persist, consult a healthcare professional.

Back to Gut Health →Frequently asked.
Common questions about how OptiLabs works: testing, supplements, clinician review, returns and timing.
Can I take this alongside other probiotics?
Yes. The Bacillus subtilis in Green-Biotic is a spore-former that occupies a different ecological niche to Lactobacillus and Bifidobacterium species. It generally stacks well with other probiotic supplements.
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.
