Kim Kardashian Relaunches Energy Drink Featuring Paraxanthine Instead of Caffeine

Kim Kardashian has relaunched the energy drink Update as a co-founder, replacing caffeine with paraxanthine, an ingredient naturally produced in the body when caffeine is metabolized. Marketed as a zero-calorie, sugar-free, and artificial flavor-free alternative, paraxanthine is promoted as a smoother stimulant that may enhance alertness and focus with fewer side effects like jitters or crashes. However, while early studies show potential benefits, long-term human research on paraxanthine's safety and effects remains limited.
