Your caffeine levels peak about 1-hour after consumption and then start to decrease gradually. Based on your reaction to caffeinated beverages, you probably already have a hunch as to whether you’re a fast or slow caffeine metabolizer. Meanwhile, energy drinks can have anywhere from 60 to 250 mg of caffeine per serving. 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. The enzyme is highly genetically polymorphic. Fast metabolizers of caffeine may have a high caffeine tolerance. On the other hand, studies suggest that slow metabolizers who drink coffee: It’s important to note that just because certain genotypes are associated with a disease, it doesn’t necessarily mean that everyone with that genotype will actually develop the disease. Selfhacked LLC does not provide medical advice, diagnosis, or treatment. The good news is that once you balance your hormones with the help of a doctor, it’s likely you’ll be able to tolerate caffeine again.

The information from animal studies is given solely for information purposes and will be updated as soon as new findings from human studies become available. In this case, opt for organic options or buy from companies that are transparent about the process they use. If you carry 1 or two "bad" copies of this gene, it will slow your ability to process your caffeine intake - and you may be more sensitive than someone else. So if you’re a slow caffeine metabolizer, should you be cutting out caffeine from your routine entirely? She's been featured in the New York Times, Marie Claire, Forbes, SELF, The Times, Huffington Post, and Travel + Leisure. There’s a gene that determines how caffeine impacts you. Let’s look at CYP1A2 in table 4. 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 [. One well known substrate of CYP1A2 is caffeine; individuals who carry one or more CYP1A2*1C alleles are "slow" caffeine metabolizers, whereas carriers of the variant CYP1A2*1F are "fast" caffeine metabolizers. Procyshyn RM, Su J, Elbe D, Liu AY, Panenka WJ, Davidson J, Honer WG, Barr AM. We believe that the most accurate information is found directly in the scientific source. March 5, 2018 Shari Basch.

If you’re consuming more than that, it might be worth cutting down your caffeine intake, especially if you’re a slow caffeine metabolizer or are experiencing any of the side effects of too much caffeine listed above. Read on to find out more about this enzyme, and factors that can increase or decrease it. is a clickable link to peer-reviewed scientific studies. Baseline levels of the enzyme may be similar between the two, but ‘A’ is associated with higher “inducibility”, which means the enzyme becomes more active in the presence of inducers such as caffeine or cigarette smoke [14, 10, 15]. The information on this website has not been evaluated by the Food & Drug Administration or any other medical body. This means that those having the A/A genotype will process caffeine and other substances metabolized by CYP1A2 much quicker, and these substances will have less effect on the body. The enzyme CYP1A2 is responsible for metabolizing caffeine in the body and determines whether the individual is a slow or a fast caffeine metabolizer. SelfDecode allows you to dig deep inside your genetics and find the genes that may be underlying chronic health issues. Lower/undetectable plasma concentrations may increase probability of pharmacotherapy failure Select alternative drug not predominantly metabolized by CYP2D6 : Strong . J Clin Psychopharmacol. Note that ethnic differences exist in CYP2D6 activity. It is also the key enzyme responsible for metabolizing caffeine. CYP1A2 Ultrarapid metabolizer genotype . • The activity of CYP1A2 alleles is largely determined by environmental factors and genetic variability. CYP1A2: Caffeine tolerance. … Chris Kresser, LAc recently made an excellent review of how coffee can be good or bad for you based on whether you are a fast or slow metabolizer of caffeine. Join SelfHacked today and start the journey of improving your life. Even if you’re a fast caffeine metabolizer, you can still experience side effects of too much caffeine such as: According to Mayo Clinic, a healthy caffeine intake can be up to 400 milligrams (mg) a day. If you have two “fast” versions, you’re considered a fast caffeine metabolizer. More than 40 single nucleotide polymorphisms (SNPs) of the CYP1A2 gene have been discovered so far .African and Asian populations seem to have lower enzyme activity .rs762551 A/A is a fast metabolizer, while C/C and AC are slow metabolizers. In contrast, if you have one or two versions of the “slow” version of CYP1A2, you’re labeled a “slow” caffeine metabolizer, meaning you clear caffeine from your system about four times slower than your quick metabolizing counterparts, says Dr. Lester. The cytochrome P450 (CYP)1 enzyme debrisoquine 4-hydroxylase known as CYP2D6 is involved in the oxidative metabolism of many different classes of commonly used drugs, including neuroleptics, tricyclic antidepressants, selective serotonin reuptake inhibitors, β-adrenoceptor blockers, and antiarrhythmics (1)(2). A homozygous, that is, AA genotype represents individuals that can rapidly metabolize caffeine. Genetic variations in these enzymes may cause changes in their activity and result in differences in … Caffeine is the most common “drug” in the world and after water, coffee is the most popular beverage on earth. An enzyme called cytochrome P450 2C19 (CYP2C19 “Sip – 2 – See – 19”) helps to process some medications including clopidogrel (Plavix®), voriconazole (Vfend®), and … 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. Are you worried about your pre-existing health problems? You can read more about CYPs and CYP metabolizer types here. The enzyme efficiency varies between individuals. More than 40 single nucleotide polymorphisms (SNPs) in the CYP1A2 gene have been discovered so far [2]. Estrogen and caffeine are both broken down in the liver by the CYP1A2 enzyme. Cytochrome P450 (CYP) 2D6 and 1A2 are enzymes that metabolize many psychotropic medications. “Women that have estrogen dominance often do not have an abundance of this enzyme and therefore should not consume caffeine as they will also have a hard time detoxing it,” explained Dr. Lester. read more about CYPs and CYP metabolizer types here.

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]. In the body, CYP1A2 accounts for around 95% of caffeine metabolism. And he zeroed in on one gene in particular, CYP1A2, which controls an enzyme – also called CYP1A2 – that determines how quickly our bodies break … Joe Cohen won the genetic lottery of bad genes. In the end, there’s no cut and dried equation for how much caffeine you should consume. Increased metabolism to less active compounds when comapred to extensive metabolizers. Atomoxetine (Strattera in the U.S.) is another drug significantly metabolized via CYP2D6. Watch a video about Shauna’s story. Caffeine acts as a natural stimulant and for this reason, the FDA has it listed as both a food and a drug. Hi, recently got some genetic testing done and most of my enzymes came back relatively normal, except for CYP1A2, for which I have the ultrarapid metabolizer genotype (-3860G>A - G/A, -2467T>DELT - T/DELT, -163C>A - C/A). She has a masters degree in physiology and complementary and alternative medicine from Georgetown University and is the former health editor at mindbodygreen. This could indicate an underlying health concern, such as estrogen dominance.

Caffeine is a bitter, white substance that’s found naturally in more than 60 different plants, including coffee beans, tea leaves, and kola nuts, which are used to make soda. These can increase CYP1A2 activity, according to human studies: These can increase CYP1A2 activity in animals: These can decrease CYP1A2 activity based on human studies: These can decrease CYP1A2 activity in animals: It’s important to stress that what’s found in animals, doesn’t always match what’s later found in humans. Genetic testing for CYP2D6 activity can be performed, but it is not yet a routine procedure. 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. The CYP1A2 gene encodes a member of the cytochrome p450 family of proteins, which metabolize nutrients and drugs. ultra-rapid metabolizer; extensive metabolizer; intermediate metabolizer ; poor metabolizer; As science and medicine progress, doctors can increasingly rely on genetics when it comes to diagnosis and treatment decisions. “I don’t typically test for CYP1A2 in isolation,” explained Dr. Lester. CYP1A2 activates cancer-causing agents such as aromatic heterocyclic amines, polycyclic aromatic hydrocarbons (PAHs), and aflatoxin B1 [5]. The ultra-rapid metabolizer pheotype may be identified, but overlaps completely with the extensive metabolizers. You have two copies of the CYP1A2 gene—one inherited from each of your parents—and each can be either a “fast” or “slow” version of the gene. “A general rule is to go by halves. 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]. The enzyme CYP1A2 increasingly isinvolved in drug interactions as newmedications metabolized by thisenzyme are released. These are enzymes that eliminate most of the drugs and toxins from the human body [1]. Caffeine can also be hiding in places you might not expect. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. Turning to other caffeine-free drinks can help you ease the transition. People who have the ‘CC’ genotype of this SNP are rapid metabolizers (more active enzyme), while ‘CT’ and ‘TT’ genotypes are slow metabolizers (less active enzyme). Recently, researchers discovered these variations in caffeine tolerance can be traced back to genetic differences, which brings us to the CYP1A2 gene. We do not aim to diagnose, treat, cure or prevent any illness or disease. Individuals with two copies of the CYP2C19*17 polymorphism are typically classified as ultra-rapid metabolizers. Article PubMed Google Scholar 2. Boost your immune system by optimizing your entire body with a gene-based approach to your health. 5 Steps that May Regenerate the Liver Naturally, 3+ Promising Health Benefits of Tamarind + How to Eat It, Toxins, such as aromatic heterocyclic amines (in cigarette smoke, charbroiled meat), polycyclic aromatic hydrocarbons (in cigarette smoke, diesel exhaust, pollution), and aflatoxin, Are more likely to benefit from caffeine as an athletic performance booster [, Are less likely to develop high blood pressure (hypertension) and heart disease when they drink coffee [, May be at a higher risk of developing high blood pressure (hypertension) and heart disease when they drink coffee regularly [, May have a lower risk of breast cancer (women). These then need to be neutralized by other enzymes. Individual Genes Tested. The function of this CYP will likely be diminished to such a degree that the person will convert from an Intermediate Metabolizer into a Poor Metabolizer. The difference is not clinically significant. Posted by 12 months ago. CYP1A2 activity shows a remarkable degree of variation (up to 40-fold) between individuals based on their genes, ancestry, and environmental factors (e.g. 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. Apart from the liver, CYP1A2 has also been detected in the pancreas and lungs [2]. 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. A plus sign next to the number “[1+, 2+, etc...]” means that the information is found within the full scientific study rather than the abstract. People with ‘AC’ and ‘CC’ genotypes (slow metabolizers) process caffeine and other substances metabolized by this enzyme more slowly, which is why they can have more of an effect on the body. 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. Their plasma levels to dose ratios of CLO (median; range, 0.34; 0.22 to 0.40 ng × day/mL × mg) were significantly lower than ratios calculated from another study … Poor Metabolizer: A poor-metabolizing enzyme has very low activity. CYP1A2 Genetic Variants: One of the fun things to find out from your CYP1A2 genes is whether you are a fast or slow metabolizer of caffeine. Some people (ultra-rapid metabolizers) should not use Cerdelga because they break down the drug rapidly and may not benefit from it. CYP1A2 is an important enzyme that helps to break down toxins in our bodies. To get specific, caffeine targets the central nervous system and makes you feel more awake, energized, and alert. 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. You can find golden milk or turmeric lattes in many coffee shops and cafes and it is naturally caffeine-free. Caffeine is metabolized by a liver enzyme coded by the gene CYP1A2.

It’s all about evaluating your relationship with caffeine and figuring out what’s best for your lifestyle and genetics. 1. This is because CYP1A2 turns the pro-carcinogenic molecules into carcinogens, which then have to be removed from the body. More specifically, it may depend on one gene—called CYP1A2—that determines how your body metabolizes the caffeine found in fan favorite beverages like tea, coffee, and soda. Review of risperidone … Note that each number in parentheses [1, 2, 3, etc.] As Dr. Lester explained, “Each of these beverages have different amounts of caffeine with tea being the lowest. Rapid or Ultrarapid Metabolizers: These enzymes are very active, often breaking down drugs before they can have any effect. This enzyme is one of the cytochrome P450 monooxygenases (CYPs). When you’re cutting back on caffeine, Dr. Lester recommends going slowly or you might experience caffeine withdrawal symptoms like headaches, irritability, and fatigue. “For someone like me who does have that genetic variant, I do not have caffeine after 8 a.m. otherwise it will be difficult for me to fall asleep at night,” she said. Kang YS(1), Park SY, Yim CH, Kwak HS, Gajendrarao P, Krishnamoorthy N, Yun SC, Lee KW, Han KO. A higher dose may also be required in order to reach the expected outcome of the medication. CYP1A2*1F has been associated in many studies with increased inducibility of CYP1A2 by, e.g ... slow and fast metabolizer phenotypes were reported based on the metabolism of the chemical carcinogen acetylaminofluorene in a panel of human liver microsomal preparations. It’s often described as a cognitive and physical performance enhancer. But proceed with some caution. Such people have two copies of the fast variant. You can test for the caffeine gene through a simple saliva or blood test that analyzes your DNA. Consider this case: Two patients each take the same dose of the same antidepressant medication. Among CYP1A2inducers, smoking is probably the mostimportant, but the usual enzyme inducerssuch as rifampin and barbituratescan also substantially i… Close. I’m a rapid metabolizer for dexedrine, and I’ll tell you, finding a doctor who’s willing to treat me with the doses I need has been a nightmare. Required fields are marked *. The same amount of caffeine will, therefore, tend to have more negative effects on CYP1A2 slow metabolizers. People with ‘AA’ genotype (fast metabolizers) processes caffeine and other substances metabolized by this gene much more quickly (when induced), and these substances will have less of an effect on their bodies. In fact, Dr. Lester is a slow caffeine metabolizer herself and still enjoys her daily dose of caffeine.

Here’s how to use it to your…. The most obvious choice is the caffeine-free version of your favorite coffee or tea-based beverage. Ultra-rapid metabolizer: 0.03 (0.02 to 0.06) Extensive metabolizer: 0.08 (0.04 to 0.17) Intermediate metabolizer: 0.56 (0.30 to 1.0) Poor metabolizer: 2.5 (1.8 to 4.1). Is caffeine bad for you? The speed of this decline depends on your CYP1A2 gene, which controls an enzyme (also called CYP1A2) that is in charge of breaking down any caffeine that enters the body. In addition, CYP1A2 variants have been associated with heart disease risk. Learn how your comment data is processed. For CYP2D6 and CYP3A4, similar problems arise concerning Citalopram. Although a R-to-9-OHR concentration ratio >1 generally indicates a poor metabolizer, it could also indicate the presence of a powerful CYP2D6 inhibitor. The genetics of CYP2D6 has been extensively studied, and individuals can be divided into 4 groups. An ancient Ayurvedic tradition, golden milk is a creamy, lightly sweet beverage that contains turmeric powder and steamed milk—and oftentimes honey and cinnamon, vanilla, and other spices. View now. According to Dr. Tiffany Lester, M.D., physician and medical director at Parsley Health San Francisco, “These are the people that can have an espresso and go right to sleep!”. Variations in the genes responsible for caffeine metabolism also affect how you respond to certain medicines. Studies suggest that African and Asian populations may have lower enzyme activity on average [5]. The CYP1A2 gene made headlines a few years ago when a study, published in the Journal of the American Medical Association, showed that slow metabolizers who drink more than four cups of coffee per day have an increased risk for heart disease. The CYP3A4*18 genotype in the cytochrome P450 3A4 gene, a rapid metabolizer of sex steroids, is associated with low bone mineral density.
