The scoop on C O F F E E

October 21, 2016

 Have you always wondered why you can drink coffee before bed and sleep just fine but your neighbor...not so much?


Most will attribute it to each individual's caffeine tolerance.


However, did you know there is actually a much deeper reasoning than someone's tolerance alone?!


It starts with your genetic predisposition to metabolize caffeine.


CYP1A2 is the exact enzyme that determines whether you are a fast caffeine metabolizer, meaning, you can tolerate more, or a slow metabolizer, meaning you can tolerate less. CYP1A2 is responsible for over 90% of caffeine clearance. This gene can even be linked to an increased risk factor for diseases such as Parkinson's, hypertension and heart disease (Eng-King, T, et al., 2007).


This enzyme, CYP1A2 may have two different variations, each of which will play in to how quickly or slowly you will metabolize caffeine following consumption.
