While Cofer’s total caffeine intake would vary depending on what kind of soda and energy drink he’s reaching for, when you add it all up he’s likely hitting between 300 and 450 milligrams of caffeine per day. You might be thinking, “That’s a lot of caffeine.” But is it too much?
Everyone varies widely as far as how sensitive they are to caffeine and how quickly it metabolizes and leaves their body. You’ll know if you’re on the more sensitive side of the spectrum if you notice a quicker heart rate or increased anxiety after consuming caffeine. Additionally, those who have heart conditions, take medication that elevates their heart rate, and tend to experience anxiety should likely try to avoid caffeine.
Caffeine may also disrupt sleep, especially if consumed later in the day. Registered dietitian Susan Kitchen told Fortune that she recommends people cut off caffeine by 10:00 a.m. (or a bit later, depending on when you go to sleep), as it takes roughly 12 hours for it to leave your system entirely.
