Summary
Resveratrol, a compound found in red wine and dark-skinned grapes, will improve the function of mitochondria (energy producing components) within the leg muscles of moderate functioning older adults.
The investigators will look at the role Resveratrol plays in improving physical function by studying the connection of changes in mitochondrial function and changes in physical function.
Eligibility Criteria
Inclusion Criteria
- Ability to understand study procedures and to comply with them for the entire length of the study;
