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%.
