Daily multivitamin may help older adults stay independent

New research presented at NUTRITION 2026 indicates that daily multivitamin supplementation could help older adults maintain their independence by preserving the ability to perform everyday activities. Scientists from the Georgia Prevention Institute at the Medical College of Georgia, Augusta University, analyzed data from more than 16,000 participants aged 60 and older who took part in the COSMOS study.

Participants were randomly assigned to receive a daily multivitamin, cocoa extract, both, or a placebo. After three years, those who took the multivitamin reported significantly better functional health scores compared to the placebo group, as measured by the Kansas City Cardiomyopathy Questionnaire. The strongest improvements were observed in symptom burden and the clinical summary score, which combines symptom severity and physical ability.

The researchers highlight that functional health reflects whether individuals can continue routine activities such as dressing, bathing, walking, climbing stairs, or doing household chores without being limited by fatigue or other symptoms. These benefits may be particularly relevant for those experiencing fatigue, shortness of breath, or swelling in the feet.

Cocoa extract did not show a significant overall effect on functional health, but it was associated with a notable benefit among participants with congestive heart failure.

The study authors emphasize that multivitamins should not replace a balanced diet or regular exercise, and individuals should consult a doctor before starting any supplement. The findings are considered preliminary until published in a peer-reviewed journal.
