Multi-nutrient Supplement to Improve Physical Performance in Older Adults

Geriatric Day Hospitals (GDH) of the McGill University Health Centre and l'Institut de Gériatrie de Montreal offer comprehensive rehabilitation programs including physiotherapy and medical care, but no dietetic counselling for the attending frail population at high risk of malnutrition. This study aims to implement a multi-nutrient supplement to further improve nutritional status, physical function and capacity. A whey protein, leucine, vitamin D and omega-3 fatty acid supplement ingested during 16 weeks will be tested versus an isocaloric placebo on measures of physical performance and muscle mass and strength, in GDH participants. The specific objective of this pilot-study is to test feasibility and adherence; pilot data could lead to a larger trial.
