Gastrointestinal (GI) function plays a critical role in the absorption and bioavailability of orally administered drugs. Further, the GI tract plays a pivotal role in the bioavailability of nutrients. The availability of energy depends on intake, absorption, storage, and utilization. The absorption and bioavailability of ingested compounds depend on physiological factors such as GI motility, splanchnic blood flow, and pH of gastric secretions.

Negative nutrient balance directly affects the energy level of an individual which in turn decreases motivation and cognitive ability. The purpose of this study is to further validate the Automated Neuropsychological Assessment Metric (ANAM) Readiness Evaluation System (ARES) software for the space program.
