                                According to health authorities like the FDA, most healthy adults can safely consume up to 400 milligrams of caffeine per day. This guideline provides a general benchmark, but individual tolerance for how much caffeine is safe can vary dramatically depending on genetics, health status, and other factors. Understanding this personalized limit is key to avoiding negative side effects.
