If you might feel the effects of caffeine for too long, you can follow these 4 ways to speed up the reaction:

Empty stomach

If you are in need of a quick caffeine intake then you should take caffeine on an empty stomach and without meals if your body reacts well to it and you want to experience its effects more intensely. Naturally, we do not advocate skipping meals in order to gain more energy or for any other purpose.

Opt for stronger brews

Of course, you have the option to vary your typical coffee shop order or the coffee you prepare at home. For instance, choosing a big glass of cold brew coffee will allow you to experience a higher dosage of caffeine than you’d receive from less potent options because it is often prepared more forcefully than, say, drip coffee or espresso.

Drink coffee black

In addition to drinking your black coffee, you could want to switch up your usual caffeinated concoctions so that it’s just coffee and water.

Amount of caffeine consumed

A 4 oz cup of coffee may take longer to start working its effects than an extra-large iced coffee since caffeine is only as potent as the dose. If the effects aren’t as strong as you’d want, either drink a little bit more or go through it more quickly.

Consumption rate

Drink your coffee more quickly if you want the benefits of coffee to take less time to kick in. Similar to when you simply consume a tiny amount of coffee, sipping a large cup slowly can not provide you with the desired caffeine high.


The metabolism may be to blame if your coffee starts to take effect more slowly or more quickly than normal. You might not feel the effects of coffee for one or even two hours if your liver metabolizes it more slowly. On the other hand, if it metabolizes more quickly, you could see the effects in 15 to 20 minutes.

Allowed amount of caffeine

An adult American uses 200 milligrams of caffeine on a daily basis. This is equivalent to two five-ounce coffee cups or four 12-ounce Coke bottles. For the majority of people, consuming up to 400 mg, or four cups of coffee is not problematic. 

However, caffeine has varying effects on individuals based on their size, gender, and susceptibility to it. If you’re sensitive to caffeine, even little doses might make you feel jittery, and anxious, and have difficulties falling asleep. 

Experts in nutrition and health all agree that over 600 milligrams of caffeine per day (the equivalent of four to seven cups of coffee) are excessive.

  • Reduce your consumption of caffeine gradually.
