I’m wondering about something a bit beyond the simple “what’s the maximum dose not to exceed?”. We all know that caffeine, consumed wisely, has a very favorable benefit/risk ratio: improved focus, energy boost, better athletic performance, and even some suggested long- term health benefits from studies.
So my question is: for a healthy adult male, what would be the ideal quantity of caffeine in milligrams (mg) per day to maximize benefits (focus, energy, well-being) while minimizing downsides (anxiety, poor sleep, jitters)?
I’m not looking for the dose to pull an all-nighter or break a record, but really the “cruising” dose for optimal daily health and productivity.
No, we don’t.
That is an opinion.
And with normal human variation, no one can tell you what’s right for you. They could just say an average safe level, but again, you’re asking for someone’s opinion on risk/reward.
There’s just no way anyone could actually answer your question.
If OP quantified their performance, they could test it experimentally on themselves.
