Most of us like a cup of coffee…or any other caffeinated beverage. But sometimes the caffeine doesn’t last long enough, and start feeling tired again… There is a little trick that can make caffeine last longer in your body... You need to start eating foods that are rich in the flavonoid Quercetin.

Key Facts



It’s a plan flavanol from the flavonoid group of polyphenols.


It’s found in such foods as red onions, kale, apples, propolis, broccoli, grapes, cilantro, and goji berries.


How Does Quercetin Make Caffeine Last Longer?


There are various enzymes in your liver that fall under the P450 family.


These enzymes are responsible for metabolizing all sorts of drugs, hormones, chemicals, and toxins in the body. Quercetin significantly affects the pharmacokinetics of caffeine and its main metabolite paraxanthine and thus can significantly inhibit the caffeine metabolism and CYP1A2 activity(Xiao et al., 2014).


Consuming foods rich in Quercetin can help extend the effects of caffeine in the body via reducing its excretion/metabolism.
