Improve physical functioning

What this outcome means

Physical functioning is how well you handle everyday movements, from climbing stairs and carrying groceries to getting up from a chair. On DoseRank it maps to a defined health outcome built from human studies on gait speed, grip strength, and validated activity-of-daily-living scales – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Aging mobilityOlder adults noticing slower, less steady movement around the home.

Recovering from setbackRebuilding strength after illness, surgery, or a long bed rest.

Staying independentPeople determined to keep doing daily tasks without leaning on others.

Stack buildersAlready taking supplements such as NMN and want the dose right.
