Precision Health Solutions to Improve Sleep During Spaceflight Using Nutraceuticals
• Disruptions to sleep during spaceflight have been well documented including decreased duration and slow-wave sleep and circadian desynchrony • Frequent use of sleep-promoting medications and stimulants • Lack of a precision health approach • Current countermeasures infeasible in exploration class missions • Precision health solution: Implementation of nutraceuticals based on phenotype (observable or measurable traits)

Assessment of Individualizing lactobacillus plantarum Supplementation with Precision Health to Preserve Muscle Health in Astronauts During Long Duration Spaceflight
Muscle atrophy is an unfortunate reality seen after spending time in microgravity. Decreases in muscle strength, size, and endurance can negatively impact mission productivity and increase the risk of injury in astronauts. In preparing for long-duration spaceflight aboard future orbiting stations and interplanetary vessels, supplementation with lactobacillus plantarum has been suggested as a possible countermeasure for crew members. Early clinical trials have shown the probiotic to improve muscle strength, endurance, and associated biomarkers, even without significant physical exercise by influencing the gut-muscle-axis. While current onboard exercise protocols have significantly helped limit degradation (as seen below), individualized implementation of this supplement could not only add another layer of protection but also protect against inadequate exercise equipment on future missions due to payload constraints
