About

This study aimed to investigate the incidence and severity of GI symptoms associated with daily CM supplementation, with and without a loading phase, in healthy male and female adults.

Full description

In a 28-day single-center, single-blind, randomized clinical trial, 24 healthy participants were assigned to either Group A (5 g/day CM) or Group B (20 g/day loading dose for 14 days followed by 5 g/day maintenance). Blood and urine samples were collected at baseline and day 28 to assess safety. GI symptoms were recorded via self-report using a structured severity rating scale.
