There is growing interest in understanding the connection between concussions on physical and mental health acutely and, in retirement, on neurodegenerative diseases. In this study, we utilised a “high-impact trauma” (HIT) device to investigate the effects of multiple concussions on the motor activity, and lifespan of the adult female Drosophila melanogaster as well as reactive oxygen and nitrogen species (RONS) levels in the fly brain and body. We found that repetitive hits, while not having acute physical effects, significantly increased long-term mobility deficits, and shortened lifespan, and exacerbated oxidative stress in both the brain and body. Notably, the novel CONKA product (Withania somnifera, Curcuma longa, Melissa officinalis, Rhodiola rosea, Vaccinium myrtillus) demonstrated promising protective effects, including mitigation of motor deficits, extension of lifespan, and reduction of oxidative stress in both the brain and body of the flies. When evaluating the contributions of individual components within the CONKA formulation, Curcuma longa, despite extending lifespan, did not contribute to mobility improvement or oxidative stress amelioration. This suggests that the benefits of CONKA are largely driven by its other four components, which displayed all the positive effects evaluated. The exclusion of Curcuma longa may streamline the formulation without diminishing its brain and body effects following a history of repetitive concussions, although this would require further study to confirm. Oral bioavailability may be an issue with Curcuma longa. Taken together, the findings validate that Drosophila melanogaster is a suitable system to mimic and investigate the effects of repetitive concussions on bodies and brains and assess the effects of health products and drug therapies.
