■ NUTRITIONAL OUTLOOK 26 APRIL 2018 Brain Health of the astaxanthin supplement or a placebo for eight weeks. To test mental function, the participants performed a battery of timed calculations (i.e., the Uchida-Kraepelin test) to evaluate concentration and mental clar- ity; physical challenges were performed using a bicycle ergometer. T e researchers then measured individuals' subjective and objective perceptions of fatigue both before and after the stressor tests. Visual Analogue Scale (VAS) analysis showed a signif cant reduction in perceived symptoms of mental and physical fatigue with supplementation compared to the pla- cebo. "T ese included improvements in cog- nitive acuity, concentration, motivation, and mood," Hecht notes. Subjects also reported reduced feelings of body heaviness and irrita- tion. And while the placebo group displayed an increase in errors during the second half of the test, such an increase "was almost nonexistent" in the astaxanthin group. Sup- plementation also signif cantly lowered levels of salivary cortisol, a stress biomarker. Says Hecht, "T e study is believed to be the f rst clinical trial demonstrating that a nutra- ceutical ingredient has properties ef ective against both physical and mental fatigue." References 1.
