A study recently published in Food and Chemical Toxicology found that nothing bad really happens if you have 400 or more milligrams of caffeine a day.


The researchers analysed over 700 studies done between 2001 and 2015, and all of them were surveyed to assess the negative effects that could occur from consuming large amounts of drinks and foods that contain caffeine, such as coffee, tea, and energy drinks.


The researchers assessed the effects of “coffee, tea, chocolate, cola-type beverages, energy drinks, supplements, medicines, energy shots, caffeinated chewing gum, caffeinated sport gel, and caffeinated sport bars.”

The research looked in to see whether people suffered from behavioural problems or bone issues as a result of caffeine consumption, they also investigated levels of acute toxicity from caffeine. 


Ultimately, the study revealed that a person can consume up to 400 milligrams of caffeine per day and you won’t see any long-term damage done to your body, or your brain. 


However, if you’re pregnant, you shouldn’t have more than 300 milligrams of caffeine per day.


The study did highlight the fact that that these studies weren’t being conducted on what would happen if you were to consume well over 400 milligrams of caffeine a day.

Just to put the daily allowance into context for you:  Starbucks grandes have 310 milligrams apiece. 


So while caffeine may be good for you in small enough doses, you may not want to down 17 espresso shots - just incase.


Know your body, and if you feel like it can take more caffeine, then go for it - but if you start getting the shakes, you should probably cool it of the coffee.
