This study's design as an open-label, single-period, single-dose, randomized trial that aligns with the objective of characterizing the concentration-time profiles of four Urolithin A (Mitopure) formulations in a controlled setting. The inclusion criteria, stringent fasting requirements, standardized fluid intake and strict dietary restriction protocols ensure homogeneity among the study participants, enhancing the reliability of the outcomes.Ultimately, this clinical trial aims to contribute valuable insights into the pharmacokinetic behavior of the different Urolithin A formulations, facilitating informed decisions for future developments and applications in the realm of health and wellness.
