Phases of Clinical Trials

Phases of clinical trials refer to the four-step process used to develop and test a product’s safety, effectiveness, and real-world performance in human participants.

Each phase of a clinical trial investigates a different question, starting with basic safety and moving through effectiveness, large-scale validation, and long-term monitoring. While traditionally used in pharmaceutical development, the same phased approach is increasingly applied to clinical research for supplements, skincare, and wellness products.
