Objective: This study determined the frequency, reasons for, and side effects of energy drinks (ED) consumption among online students. Participants: Students attending an online university. Methods: Participants were recruited by email and completed a 59-question survey about their prior months ED practices using a combination of validated surveys previously published examining similar constructs in on-campus students. Results: 307 students (age = 32.4 ± 6.5yrs) completed the survey, and 88% reported consuming EDs. Students’ reasons for consuming ED included school (p < .001), work (p < .001), an event/competition (p < .001), pick me up (p < .001), lack of rest (p < .001), more energy (p < .001), and staying awake while driving (p < .001). Only individuals who consumed > 10 ED/month reported side effects of headaches (p = .01) and speeding (p=.01). Conclusions: In our sample, a majority of …

Muscle builders frequently consume protein supplements, but little is known about their effect on the gut microbiota. This study compared the gut microbiome and metabolome of selfidentified muscle builders who did or did not report consuming a protein supplement. Twenty-two participants (14 males and 8 females) consumed a protein supplement (PS), and seventeen participants (12 males and 5 females) did not (No PS). Participants provided a fecal sample and completed a 24-h food recall (ASA24). The PS group consumed significantly more protein (118 ± 12 g No PS vs. 169 ± 18 g PS, p = 0.02). Fecal metabolome and …
