Effects of Daily Geranylgeraniol GG Supplementation on Muscle Strength, Body Composition, and Aerobic Fitness in Healthy Adults Aged 30 to 60

What this Trial Is About

Researchers are evaluating the effects of daily geranylgeraniol GG supplementation on muscle strength, body composition, and aerobic fitness in healthy, physically active adults aged 30 to 60 years. This randomized, double-blind, placebo-controlled trial aims to understand how different doses of GG influence muscle health and related physiological markers over an 8-week period. Participants will be randomly assigned to one of three groups receiving daily doses of either a placebo olive oil, 150 mg GG, or 300 mg GG. Supplements are taken with water at a consistent time each day for 8 weeks. The study includes a screening visit and testing at baseline, week 4, and week 8 to track changes over time. During the study, participants undergo strength testing bench press and leg press, muscular endurance assessments, aerobic capacity measurement via treadmill, and body composition analysis using advanced techniques. Blood samples will be collected to monitor metabolism-related biomarkers and safety. Participants also complete mood and quality of life questionnaires, provide dietary logs, and give fecal samples. Safety is tracked throughout, and the main outcomes focus on changes in strength and fat-free mass from start to week 8.
