how do i know what amount of caffeine is right for me
This means that if your parents seem to get strong effects of caffeine on a small amount-a half cup, say-you are likely to have the same kind of response. Look to your family tree, to get a clue of how much caffeine might work for you in a health promoting way. This does vary! 7.he response is much less. This is call attenuation. Same dose of caffeine, less effect. With this knowledge, the best way to have optimal effect of caffeine is to limit consumption to about 300 mg per day, and consume it ONCE a day â at the time you want to be most alert, and want the maximal effect.
