What this trial studies
This is a single-arm, open-label, virtual trial enrolling 35 healthy women aged 21-45 who exercise regularly. Participants will take the creatine powder daily for eight weeks and complete questionnaires at baseline, week 4, and week 8 to track changes in lean muscle, endurance, hormonal wellness, digestion, and hair/skin/nail health. No control group is used; outcomes are based on self-reported measures. The study is sponsored by Clean Nutraceuticals with Citruslabs as a collaborator and site contact in Las Vegas. Results will inform whether the product can support multiple aspects of wellness in this population.
Why it matters
Potential benefit: If successful, participants may experience improvements in muscle development, endurance, hormonal comfort, digestion, and skin health.
How similar studies have gone: Similar supplement studies in healthy, active populations have shown modest benefits in muscle and wellness measures; this study contributes additional, self-reported wellness data.
