This study examines a multi-ingredient nutraceutical designed to support several areas of health in older adults, including muscle strength, cognitive function, immune response, and inflammation. Unlike single-drug treatments, the ingredients work together through complementary mechanisms across different biological systems. Since this combined approach has not been clinically tested before, the trial will provide early evidence on functional outcomes and biomarker changes. The main goal is to measure improvements in muscle performance, while secondary goals include evaluating effects on cognition, immunity, inflammation, safety, and tolerability in older adults.
