Clinical Trial Summary

This placebo-controlled RCT tests whether dietary supplementation with curcumin maintains or improves cognitive and physical function in older adults who are at high risk of functional decline due existing (mild) functional impairments and elevated biomarkers of inflammation and explore the association between functional changes and changes in biological indicators of active inflammation.

Intervention

Drug:
• Curcumin
Participants will be given curcumin (1000 mg/day), and will be instructed to consume two 500 mg capsules prior to breakfast every morning with a glass of water. Participants will be instructed to follow this dosing regimen throughout the entire three-month treatment period. Compliance with the dosing regimen will be monitored both through interview and by counting capsules left at monthly clinic visits.
• microcrystalline cellulose
Participants will be instructed to consume two capsules prior to breakfast every morning with a glass of water. Participants will be instructed to follow this dosing regimen throughout the entire three-month treatment period. Compliance with the dosing regimen will be monitored both through interview and by counting capsules left at monthly clinic visits.
