Design outcomes

Primary

MeasureTime frame
Mean change in plasma free amino acid concentrations (total amino acids, essential amino acids, branched-chain amino acids).Timepoint: Baseline, Day 30, and Day 60.

Secondary

MeasureTime frame
Mean change in muscular strength assessed by one-repetition maximum (1RM) testing (bench press, leg press, and deadlift). Mean change in muscle hypertrophy and body composition parameters, including skinfold thickness and body mass index (BMI). Mean change in oxidative stress and inflammatory biomarkers, including serum creatine kinase (CK), high-sensitivity C-reactive protein (hs-CRP), and fasting serum insulin levels. Mean change in gastrointestinal-related quality of life assessed using the SF-36 health survey questionnaire. Safety and tolerability assessed by the incidence of adverse events (AEs) and treatment-emergent adverse events (TEAEs), changes in vital signs, and laboratory safety parameters (haematology, hepatic, and renal function tests)Timepoint: Baseline, Day 30, and Day 60
