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. 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. The drink also contains alpha-GPC, L-theanine, and sucralose. 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.
