The Regular One.
If you only ever try one Good One, this is usually it. The Regular One is our gut-system formula — the One picked for daily regularity, the thing most people mean when they say "I want a probiotic." It is the most-shipped One in the line, and the one with the most direct mechanism.
How it works
The Regular One pairs Bifidobacterium animalis subspecies lactis and Bifidobacterium longum — both Bifidobacterium, both at home in the lower colon — on a flaxseed prebiotic matrix that feeds them. The mechanism is short-chain fatty acid (SCFA) production. SCFAs do two things at once: they feed the colon lining (the cells there literally eat SCFAs for fuel) and they stimulate the gut's natural peristaltic rhythm. They also help the bowel retain moisture, which is half the regularity story.
What the data says
Tested across six randomised controlled trials in chronic functional constipation (n > 900, 2015–2023). In our own customer cohort: 932 picked, 68% improved on stool-frequency endpoints, 11-day median to first effect. The other 32% didn't — for them, the next step is usually Floré Custom, a personalised 5-strain blend based on the customer's own gut sequencing.
How to take it
One capsule a day, with or without food. The Regular One is shelf-stable; no refrigeration needed. Single bottle $49. Pair it with The Bright One ($90 for a Pair, saves $8) if the rough days are also rough on mood.
