In case you haven’t heard of the study you can read more at the following link: Study Link
The story was covered by HighTimes. Basically these students were giving way too much caffeine and ended up in intensive care. There’s been studies that you can safely have up to 400mg of caffeine if you’re a healthy adult, these two students had 30 grams. Not sure if that number is combined or each but either way that’s an insane amount.
The odds you’ll consume that much are basically impossible but it’s not actually too difficult to go over 400mg. 2 regular Rockstar Energy drinks would be 480mg, already over the limit. So start cutting back and getting caffeine free replacements.
