Evaluation of Urolithin A and Fisetin on Improving Sleep and Aging Biomarkers in Middle-Aged and Older Adults: A Randomized Controlled Trial

Обзор

The goal of this clinical trial is to evaluate the effects of Urolithin A (UA) and Fisetin on improving sleep and aging biomarkers in middle-aged and older adults. The main questions it aims to answer are: Can UA and Fisetin improve sleep quality in middle-aged and older adults? Do these substances have a positive effect on aging biomarkers, such as inflammation, oxidative stress, and aging-related proteins? Researchers will compare four groups: Placebo group (a look-alike substance that contains no drug), 500 mg UA group, 500 mg Fisetin group and 300 mg UA + 200 mg Fisetin group. Participants will: Take the assigned capsules daily after breakfast for 12 weeks. Attend three clinic visits (baseline \[Week 0\], mid-intervention \[Week 4\], and post-intervention \[Week 12\]) including blood tests, sleep quality assessments (PSQI scale, actigraphy, polysomnography), and analysis of aging biomarkers (DNA methylation, inflammatory cytokines, etc.). Keep a sleep diary, complete a dietary survey, assess mental health, and measure frailty indicators. Provide stool and urine samples at baseline and post-intervention for gut microbiome and metabolite analysis. This trial aims to provide scientific evidence for the development of new nutritional intervention strategies to improve the healthy aging.

Подробное описание

The accelerating population aging has exacerbated the burden of chronic diseases among middle-aged and older adults, with sleep disorders emerging as a core health issue that forms a vicious cycle with aging. Urolithin A and Fisetin as dietary bioactive components have gained attention for their potential health benefits, including anti-aging, anti-inflammatory, and antioxidant properties. However, researches on their effects in sleep and aging remain limited, and clinical evidence for their combined intervention is currently lacking. This study aims to evaluate the effects of Urolithin A and Fisetin on improving sleep and aging biomarkers in middle-aged and older adults, providing scientific evidence for developing new scientific dietary strategies. It is a randomized controlled trial. A total of 80 participants will be recruited and randomly assigned to four groups: control group, Urolithin A 500 mg group, Fisetin 500 mg group, and Urolithin A 300 mg + Fisetin 200 mg group. The intervention period will last 12 weeks, with all participants taking one capsule of the intervention substance or placebo daily after breakfast. Primary outcomes include subjective and objective sleep quality assessments and frailty assessment. Secondary outcomes include metabolic, immune and inflammatory markers, gut microbiota analysis and quality of life assessment. Participants will undergo three follow-up assessments: baseline (week 0), mid-intervention (week 4), and end of intervention (week 12). Data will be analyzed using SAS 9.4 following the intention-to-treat principle. It is expected to provide preliminary data on the single and combined effects of Urolithin A and Fisetin on improving sleep and aging biomarkers in middle-aged and older adults, as well as reveal their potential synergistic effects. The rigorous and innovative design will serve as a reference for future mechanistic studies, which has important public health significance.
