Clinical Trials

A clinical trial is evaluating the impact of consuming stevia-sweetened beverages on oral health outcomes, specifically oral pH, the oral microbiome, and dental plaque dynamics. Sponsored by a hospital facility, the Hospital Infantil de Mexico Federico Gomez, this combined Phase 1 and Phase 2 investigation aims to clarify the localized physiological impact of stevioside on dental biofilm accumulation and microbial ecosystems. According to trial records, the study's current recruitment status is listed as not yet recruiting.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Stevioside, a diterpene glycoside, acts by interacting with bacterial cell membranes and metabolic enzymes, thereby inhibiting extracellular polysaccharide synthesis and enzymatic acid production in oral microflora. This biochemical blockage suppresses bacterial acidogenesis and cellular adhesion, thereby stabilizing oral pH, preventing dental plaque accumulation, and modulating oral microbiome homeostasis.

Appendix RUO and cGMP Quality Standards
