Probiotics are live microorganisms intended to confer health benefits when consumed in adequate amounts. They are widely used in dietary supplements, functional foods, beverages, and emerging microbiome-focused innovations.
Unlike traditional nutraceutical ingredients, probiotics are living systems. Their safety and efficacy depend on strain identity, viability over time, formulation, storage conditions, and real-world handling. Clinical research is essential to demonstrate that a probiotic remains stable through shelf life, survives digestion, and delivers measurable, reproducible benefits in humans.
Well-designed probiotic clinical trials support structure/function claims, inform GRAS and regulatory strategies, and build confidence with regulators, retailers, investors, and consumers.
Probiotic clinical trials present unique challenges not seen with conventional nutraceuticals. Viability can be affected by temperature, humidity, transport, subject handling, and study duration. Without appropriate stability planning and monitoring, even strong study designs may produce inconclusive or misleading results.
dicentra designs probiotic studies that account for these realities—integrating stability considerations, real-time monitoring, and regulatory expectations to ensure outcomes reflect true product performance rather than formulation or handling failure.

A probiotic clinical trial requires a clearly defined strain or formulation, a scientifically justified protocol, appropriate clinical endpoints, ethical approval, and a plan for stability and product handling throughout the study. Regulatory expectations may also require safety data, stability commitments, and documentation supporting product quality and consistency.
Clinical trials are not always legally required for probiotics marketed as dietary supplements or foods, but they are often essential to support structure/function claims, differentiate products, and meet expectations from regulators, retailers, investors, and consumers. Clinical evidence significantly strengthens product credibility and market positioning.
Timelines vary based on study design, endpoints, population, and duration of product exposure. Most probiotic clinical trials range from several weeks to several months, with additional time required for protocol development, approvals, data analysis, and reporting. dicentra designs studies to balance scientific rigor with efficient execution.
Endpoints depend on the intended benefit and target population. Common endpoints include gastrointestinal comfort and function, immune response markers, inflammatory biomarkers, quality-of-life measures, safety and tolerability outcomes, and other clinically relevant indicators aligned with proposed claims.
Probiotics are live microorganisms, and their viability can be affected by temperature, humidity, transport, storage, and subject handling. Stability data helps demonstrate that the investigational product meets specifications for the duration of the study, ensuring that results reflect true efficacy rather than product degradation.
Yes. While GRAS determinations primarily focus on safety, human clinical data can support the overall safety narrative, demonstrate intended use conditions, and strengthen regulatory confidence—particularly for novel strains or differentiated formulations.
Clinical trials are a key tool for substantiating structure/function claims by demonstrating measurable effects in humans. Well-designed studies help ensure claims are truthful, not misleading, and defensible under regulatory scrutiny.
Yes. dicentra offers integrated CRO and regulatory consulting services, aligning clinical trial design with regulatory expectations, claim strategy, and long-term market goals. This integrated approach reduces risk, streamlines execution, and improves overall study value.
dicentra supports clinical research for probiotic dietary supplements, functional foods and beverages, synbiotics, postbiotics, and novel or proprietary strains intended for human consumption.
If you are launching a new strain, pursuing differentiated claims, preparing for regulatory review, or seeking stronger commercial credibility, a clinical trial is often advisable. dicentra offers early-stage assessments to determine whether clinical research is appropriate for your product and goals.
