What to expect, and when.
A daily ritual, three quiet milestones. Your blend works alongside your existing routine, small shifts at first, then steady stability, then refinement.
Colonisation begins
Your strains start their work alongside your existing gut bacteria. Some people notice the first quiet shifts in digestion, a sign of activity, not a problem.
Stability and results
Digestion settles into a clearer rhythm, energy steadies, and your microbial diversity climbs toward its target range. The blend becomes part of your routine.
Refine and re-tune
