Individual Genes Tested. CYP1A2 is an important detox enzyme that breaks down toxic chemicals, drugs, hormones, and other products of metabolism in order to eliminate them from your body. 2014;34(1):17–22. 1. The same amount of caffeine will therefore tend to have … Kombucha and chocolate are two hidden sources of caffeine that you might not be taking into account. • The activity of CYP1A2 alleles is largely determined by environmental factors and genetic variability. Heritability studies suggest that genetic variants may determine up to 75% of CYP1A2 enzyme activity, while food, supplements, and smoking are responsible for the rest [9, 10]. As Dr. Lester explained, “Each of these beverages have different amounts of caffeine with tea being the lowest. CYP1A2 activity shows a remarkable degree of variation (up to 40-fold) between individuals based on their genes, ancestry, and environmental factors (e.g. It is possible to have side effects even with a very low drug dose, because the enzyme is very slow to break down the drug.

This CYP has only one functioning allele, which is inhibited by citalopram. A patient who will metabolize a drug even faster than a rapid metabolizer and usually before the body is able to attain the desired effect. It’s found mainly in the liver [1, 2]. Both increased and decreased CYP1A2 enzyme activity have been linked to increased risk of cancer [11, 12, 13]. This enzyme is activated via the aryl hydrocarbon receptor (Ahr) [5]. Not every beverage contains the same amount of caffeine. According to Dr. Lester, if you’re dependent on caffeine to function and get through the day—and you’re still tired even after getting plenty of sleep—it could be a sign that you have underlying adrenal fatigue. Studies have found that fast metabolizers: A meta-analysis of 21 studies with over 10k people suggests that the ‘AA’ genotype may be associated with a higher risk of lung cancer, but a lower risk of bladder cancer [11]. The most obvious choice is the caffeine-free version of your favorite coffee or tea-based beverage. It is used primarily in children with ADD/ADHD, who are typically started at a low dose, then that dose is increased in increments until an effective dose is found for the child. In this particular case, substances that affect CYP1A2 in animals are in some cases confirmed to have the same effect in humans, while in others they are shown to have no effect [7]. She is passionate about releasing the most accurate science and health information available on topics, and she's meticulous when writing and reviewing articles to make sure the science is sound. About 1.6 billion cups of coffee are consumed every single day worldwide; in other words, it’s deeply ingrained in our culture and our daily routine. Bishop JR, Pavuluri MN. SelfDecode allows you to dig deep inside your genetics and find the genes that may be underlying chronic health issues. Finally I’ve found a competent doctor who realizes what any specialist with nine years of medical training should know, that some people are simply rapid metabolizers of certain medications. The good news is that even if you’re a slow caffeine metabolizer, you can enjoy your morning coffee as long as you’re wise about your consumption. Gretchen Lidicker is a writer, researcher, and author of the book CBD Oil Everyday Secrets: A Lifestyle Guide To Hemp-Derived Health & Wellness. Archived. If you have two “fast” versions, you’re considered a fast caffeine metabolizer. Therefore variations in the CYP1A2 gene can have a big impact on how coffee will affect our bodies. We are dedicated to providing the most scientifically valid, unbiased, and comprehensive information on any given topic. Prevalence and patterns of antipsychotic use in youth at the time of admission and discharge from an inpatient psychiatric facility. In a study of 717 seniors who drank a lot of coffee, rapid metabolizers tended to have a lower bone mineral density (BMD) than slow metabolizers [20]. In addition to the wild-type gene (CYP2D61), at least 15 different alleles of CYP2D6, associated with deficient, reduced, normal, or increased enzyme activity, … In particular, a study found an association between drinking coffee while young and lower risk of breast cancer in women who were CYP1A2 slow metabolizer and also carriers of the BRCA1 mutation [, Cigarette smoke: dose dependently, 1.72-fold for >20 cigarettes per day [, Coffee consumption: 1.45-fold per liter of coffee drunk daily [, Meat pan-fried at high temperatures: 1.4-fold [, Cruciferous vegetables, including broccoli, cabbage, Brussels sprouts, and cauliflower [, Apiaceous vegetables (carrots, parsnips, celery, and parsley) [, Kale ingestion, unlike that of other cruciferous vegetables [.
