Effect of Astaxanthin Supplementation on Psychophysiological Heart-Brain Axis Dynamics in Healthy Subjects

In the study “Effect of Astaxanthin Supplementation on Psychophysiological Heart-Brain Axis Dynamics in Healthy Subjects,” authors Shawn M Talbott, Don Hantla, Bob Capelli, Lixin Ding, Yanmei Li, and Christian Artaria find that the NAX supplementation lowered average heart rate at submaximal endurance intensities (suggesting a “physical” heart benefit) and improved mood state parameters (suggesting a “mental” brain benefit). While previous studies have shown NAX supplementation to improve parameters associated with heart health (antioxidant, fat oxidation, endurance) and brain health (neuro-inflammation, cognition, antidepressant/anxiolytic), these results suggest that natural astaxanthin supplementation supports the psychophysiological “heart-brain-axis” with simultaneous improvements in both physical and mental wellness.
