Official title
Effect of Different Dosages of Paraxanthine, the Major Caffeine Metabolite, on Energy and Focus: A Randomized, Double-Blind, Placebo-Controlled, Crossover Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Research has shown that acute ingestion of Paraxanthine (1,7-dimethylxanthine, PXN) can enhance various markers of focus, including memory, reaction time, and attention in healthy adults. To assess these effects, this placebo-controlled crossover trial will compare the effects of 200 and 300mg of PXN to a placebo control. Participants will abstain from caffeine for 3 days, before taking the first test/placebo product for 3 consecutive days. Participants will complete questionnaires at 30, 60, 90, and 120 minutes after ingestion on Day 1 and Day 3 of ingestion. Participants will have a 3-day washout period before trialing the next test product/placebo.
