"Clinically proven" refers to a treatment, product, or intervention that has been shown to be effective and safe through rigorous scientific research conducted on human subjects in clinical trials.

To prove that a treatment is clinically effective, researchers typically conduct randomized controlled trials (RCTs) in which participants are randomly assigned to receive either the treatment being studied or a placebo or an alternative treatment. The trials should be well-designed, well-executed, and involve a sufficient number of participants to produce statistically significant results.

In addition to RCTs, other types of clinical studies may also be conducted to gather evidence of a treatment's safety and effectiveness, such as observational studies and meta-analyses.

Once the results of these clinical studies have been analyzed and reviewed by experts in the field, they may be published in peer-reviewed journals, and regulatory agencies may use the data to make decisions about whether to approve the treatment for clinical use.

In summary, for a treatment to be considered clinically proven, it must have been rigorously tested through clinical trials, and the results must have been analyzed and reviewed by experts in the field so when you see someone who claims their products to be clinically proven, please ask for clinical trials report.
