No. It's a postbiotic, the finished compound (butyrate, via Thirdbiome GTB™) your gut would normally make for itself. There are no live cultures to keep alive or hope will colonise.

When will I notice something?

Most people feel gas and bloating ease within the first week or two. Gut-brain and systemic benefits build over the season, think months, not days.

Is it really patented?

The technology is proprietary, with a patent application filed (PCT). We say proprietary, never patented, until it's granted.

What exactly was in your trial?

A registered, randomised, double-blind RCT (CTRI/2025/09/094597): N=30 across 3 active arms over 45 days, with no placebo arm, which we disclose. The GTB arm raised stool butyrate by 74%.

Needs attention

A lot of signals are pointing the same way. Worth taking seriously, and worth looking at the gut lining rather than chasing each symptom on its own.

What's pulling your score down

BloatingBloating after most meals is the clearest signal that the gut lining is irritated.
RegularityUnpredictable digestion usually points to a gut wall that isn't getting steady fuel.
EnergyWhen the gut lining is inflamed, energy goes into managing that instead of your day.

This score is a self-assessment based on your answers, not a medical diagnosis. If symptoms persist, please speak to a doctor.
