Effects of Astaxanthin Supplementation on Metabolism, Cognition, and Physical Function in Older Adults
Sponsor: University of North Alabama
Summary
This study evaluated whether astaxanthin supplementation affects the body's ability to use fat for energy, cognitive performance, and physical function in healthy older adults. In this randomized, double-blind, placebo-controlled crossover trial, participants received both astaxanthin and a placebo during separate study periods. Neither the participants nor the researchers conducting the assessments knew which treatment participants were receiving during each period. Assessments were used to compare outcomes between the astaxanthin and placebo conditions.
