The goal of this clinical study is to learn if combining a nutritional supplement with a multicomponent exercise program can help prevent and treat frailty in community dwelling older adults. The main questions it aims to answer is: Does combining a nutritional supplement (MERITENE) with a multicomponent exercise program improve frailty and functionality in older adults? Researchers will compare: * A group receiving both the nutritional supplement and the exercise program (intervention group) * A control group receiving neither (control group) Participants: * take the nutritional supplement (MERITENE, 30g twice a day) for 180 days * attend (3days/week) supervised exercise sessions as part of the multicomponent program for 180 days (if assigned to the intervention group). * undergo regular clinical evaluations for frailty, nutritional status, cognitive function, emotional state, and quality of life. Measurements will include: Changes in frailty status, particularly gait speed, measured using Share-fi criteria, nutritional assessment using the Mini Nutritional Assessment (MNA), physical and cognitive assessments, including Edmonton Frail Scale, MMSE, and Short Physical Performance Battery (SPPB) and a complete biochemical and clinical blood analysis.
