NCT07529457

Brief Summary

This randomized, double-blind, placebo-controlled trial will assess the clinical effects of Akk09 in adults with functional constipation. Participants will receive Akk09 or placebo for 4 weeks. The study will evaluate changes in bowel habits and symptom burden, as well as alterations in host inflammatory status, immune modulation, microbial ecosystem dynamics, neuroendocrine signaling related to the gut-brain axis, and systemic metabolic responses, to characterize the overall physiological impact of BC09 supplementation.
