Study Limitations & Caveats Before You Act

Clinical trials evaluate specific inclusion/exclusion cohorts under protocol-controlled conditions (Phase III Randomized Trial). Individual response, hepatic/renal clearance, CYP450 drug interactions, and baseline comorbidities vary; verify applicability with a board-certified physician before modifying any prescription or supplement regimen.
