> small doses (up to ~5 cups / day) one cup has ~120mg of caffeine. This is 600 mg of caffeine. That's not a small dose. I would say it's above even a "moderate" dose. To be safe I looked it up, and I find up to 400 mg is considered safe. Above that is considered a high caffeine intake [1]. [1] "only limited evidence is currently available to ascertain the safety of high caffeine intake (greater than 400 mg/d for adults [...] Limited data suggest adverse health outcomes" from https://health.gov/sites/default/files/2019-09/Scientific-Report-of-the-2015-Dietary-Guidelines-Advisory-Committee.pdf https://health.gov/sites/default/files/2019-09/Scientific-Re...

> one cup has ~120mg of caffeine. This is 600 mg of caffeine. That's not a small dose That's a fairly generous estimate, but that depends on which coffee you're drinking and how it's made. I usually make a cup of coffee by using at most a teaspoon of instant coffee powder, which contains ~50mg of caffeine. So 6 cups for me would be ~300mg of caffeine. That's a small dose when compared to my >1000mg caffeine pill habit in college, which caused the amphetamine-like burnout. Though, it's good that you've brought this up - "a cup" is not a well-defined measurement of caffeine, and this elaboration resolves the ambiguity of my original post.

  Instant coffee powder has extremely low caffeine vs. other brewing methods. I'd suggest that most people, if they're drinking '5 cups a day' level, are brewing a pot of filter coffee via a drip machine. At that rate, each 'cup' (defined as 8 fl oz of coffee) should have something like ~100mg of caffeine. If a 'cup' of coffee is something like a Starbucks Venti (20 fl oz), Starbucks claims it has somewhere between 410-475mg of caffeine. Two of those and you're approaching 1000mg of caffeine alone.
