flag Kim Kardashian has launched "Update," a caffeine-free energy drink using paraxanthine, a natural byproduct of caffeine metabolism, marketed as a gentler alternative that avoids jitters and crashes. flag Early animal and small human studies suggest paraxanthine may offer similar alertness with fewer side effects and lower toxicity than caffeine, though long-term safety remains uncertain. flag The drink also contains alpha-GPC, L-theanine, and sucralose. flag While initial findings are promising, experts stress limited research and lack of regulatory approval for paraxanthine in energy drinks, urging caution and more comprehensive studies.
