"Maximizing the Benefits of Caffeine: Timing and Signs of Overconsumption"

The FDA recommends a daily caffeine limit of 400 milligrams for adults, with 100-150 milligrams providing a healthy boost. Timing is crucial, with experts suggesting waiting until 9:30-11am for the first cup of coffee to avoid unnecessary jitters. Caffeine's impact on sleep varies based on metabolism, with slow metabolizers experiencing reduced sleep when consuming coffee. It's advised to cut off caffeine intake 6-8 hours before bedtime to ensure a good night's sleep, as disrupting sleep can lead to various health issues.
