Subjects in the AstaPure Arava group reported significantly fewer URTC complaints and better overall sense of well-being. In the supplement group the total number of URTC symptoms reported such as cough, sore throat, sniffles, stuffiness, etc., were 78% lower compared to placebo, while the Global Mood State (i.e. “overall well-being”) was improved by 14% compared to no change in the placebo group. Cortisol, the primary stress hormone related to both mood and immune function, was reduced at the end of treatment in the supplement group. It was also 25% lower than the placebo group. There was no significant difference in overall microbiome indices following the endurance run. However, following supplementation, Streptococcus thermophilus values were 72% higher in the AstaPure Arava group, suggesting improved immune system regulation.
Excessive training is known to suppress immune system vigilance and increase susceptibility to many disease states, including upper respiratory tract infections. In addition, chronic overload causes psychological stress and deterioration in mood state. “Athletes building up for an endurance competition such as a half-marathon or marathon are exposed to strenuous physical and mental conditions,” explains Shawn Talbott, PhD, Chief Science Officer at Amare Global Research and co-author of the study. “The one-to-two-week period following intense endurance competition represents a period of particularly elevated susceptibility to immune deficiency and psychological stress.” Dr Solli Brawer, Chief Scientific officer of Solabia-Algatech Nutrition, explains: “These results suggest that AstaPure Arava could help improve the immune system’s acuity and improve the overall sense of well-being following stress conditions. The lower cortisol and superior microbiome parameters, suggest that immune vigilance and mental well-being are linked through the microbiome and stress response pathways. This research also adds to the growing scientific literature supporting the amazing arsenal of benefits astaxanthin together with other algal compounds, confers to our physical health and mental wellness.”
