Unfortunately, about 50 percent of the population has a variant in the CYP1A2 gene that leads to slow processing of caffeine. The usefulness of this is dubious at best - if your blood pressure is high and you're experiencing anxiety, adding a stimulant usually isn't the best idea. 2020 Dec 16;12(12):3850. doi: 10.3390/nu12123850. eCollection 2020. Coffee. Like caffeine, you may be a "fast" or "slow" metabolizer of your catecholamine hormones. It's particularly effective in those who are not habitual users. Summary By raising blood levels of epinephrine (adrenaline), caffeine promotes the … Two variants of the gene exist: the CPA1A2*1A allele results in fast caffeine metabolism, while the CPA1A2*1F allele results in slower caffeine metabolism. The study concluded that slow caffeine metabolism was associated with a higher risk of nonfatal heart attack. Caffeine-Containing Energy Shots Cause Acute Impaired Glucoregulation in Adolescents.

So if you typically pound several cups of coffee or diet soda, consider cutting back or avoiding caffeine completely. There is also evidence linking slow metabolizers with an increased risk of having a nonfatal heart attack and/or high blood pressure with higher amounts of coffee intake(6,7). Caffeine and Exercise Performance: Possible Directions for Definitive Findings. Caffeine - gives you a nice boost to your metabolism, but too much caffeine can suppress your appetite. The objective of this study was to determine whether variation in the CYP1A2 gene, which affects caffeine metabolism, modifies the ergogenic effects of caffeine in a 10-km cycling time trial..

That's right, the coffee you drink that speeds you up, that makes you feel as though you're ready to go in the morning, that liquid concoction that lights a fire underneath you whenever you need it believe it or not can actually slow your metabolism down. Genome-wide association study of caffeine metabolites provides new insights to caffeine metabolism and dietary caffeine-consumption behavior. The concentrations of caffeine and metabolites in urine have been examined as a function of age to explore the remarkably slow elimination of caffeine by human infants. In the body, CYP1A2 accounts for around 95% of caffeine metabolism. When it enters the body, caffeine raises the heart rate and blood pressure, increasing energy levels and improving the mood. Josse AR, Da Costa LA, Campos H, El-Sohemy A. Anonymous. Caffeine - gives you a nice boost to your metabolism, but too much caffeine can suppress your appetite. NLM The same amount of caffeine will, therefore, tend to have more negative effects on CYP1A2 slow metabolizers. Comments. Hypersensitivity to caffeine: These people have very low CYP1A2 activity. For these “slow metabolizers,” drinking coffee: Monitor your caffeine intake. It’s possible that too much caffeine can reduce insulin sensitivity by up to 15 percent, according to a study published in Diabetes Care. It is a central nervous system stimulant that temporarily increases your heart rate, opens your air passages, delays fatigue and allows muscles to contract easily.

Whether you start your morning with a cup of coffee or a cup of tea, caffeine remains the most popular ‘drug’ of choice for a large percentage of the population. In line with the above, in a small pilot study with 21 participants, 31% of slow metabolizers (CC or AC) reported increased nervousness after caffeine ingestion, while none of the fast metabolizers (AA) reported this effect [ 16 ]. After all, it would be good to know if you are prone to guzzling down a little too much, especially when your caffeine sensitivity scale is tipped at the wrong end. The enzyme CYP1A2 is responsible for metabolizing caffeine in the body and determines whether the individual is a slow or a fast caffeine metabolizer. However, to reach the desired effects, the quantity of caffeine consumed varies largely among individuals.

A polymorphism of the gene coding for CYP1A2, the enzyme responsible for 95% of caffeine metabolism, may potentially divide the population into ‘slow’ and ‘fast’ caffeine metabolisers 16,17. Tea and coffee consists of two properties that help boosts metabolism: ⦁ Caffeine: It is capable of stimulating an increase in the production of adrenaline, a hormone. Newly identified genetic differences reveal that caffeine metabolism is mediated by genetics related to variations of a specific gene. Body size, age, gender and genes all play a role in the speed of your metabolism. Caffeine has been used for years by runners and endurance people to enhance fatty acid metabolism. al., 2019).

Genetic studies, including genome-wide association studies, identified several loci critically involved in caffeine consumption and its consequences on sleep, anxiety, and potentially in neurodegenerative and psychiatric diseases. Several in vivo tests suggest that caffeine metabolism is dose-dependent, leading to nonlinear clearance (Denaro et al., 1990) ... which are also substrates for CYP1A2, interact with caffeine metabolism and slow caffeine clearance (Carrillo and Benitez, 2000). Approximately fifty percent of the population possesses the slow metabolizing allele, or variation of the gene, meaning these people process caffeine in the liver at a much slower rate than those who are identified as fast metabolizers. All these factors will be reviewed in the present document and discussed in light of the most recent data concerning the genetic variability affecting caffeine levels and effects at the pharmacokinetic and pharmacodynamic levels that both critically drive the level of caffeine consumption. Caffeine-consuming mothers who were CYP1A2*1F fast oxidizers and NAT2 slow acetylators had non-significantly elevated estimated risk for an NTD-affected pregnancy (OR: 3.10 95% CI: 0.86–11.21). Epub 2012 Aug 1. Part of coffee’s benefits come from caffeine, a psychoactive stimulant drug. Dr. El-Sohemy suspects that because caffeine hangs around longer in a slow metabolizer, it has more time to act as a trigger of heart attacks. I told my doctor about this a while ago.

Caffeine metabolism DNA testing The CaffeineGEN™ test by Consumer Genetics is a simple, accurate genetic test that will tell you if you have the fast or slow caffeine metabolizing gene. We start reaching a better picture on how a multiplicity of biologic mechanisms seems to drive the levels of caffeine consumption, although much more knowledge is still required to understand caffeine consumption and effects on body functions. COVID-19 is an emerging, rapidly evolving situation. By testing for this variant of the CYP1A2 gene, you will learn whether you are a fast or slow metabolizer of caffeine. 2020 Nov 3;9(21):e016737. In a landmark study published in the "American Journal of Clinical Nutrition" in 1980, scientists found that the caffeine in coffee boosts metabolic rate in humans, no matter their weight. These individuals are “slow” caffeine metabolizers. Intake of coffee was associated with an increased risk of nonfatal MI only among individuals with slow caffeine metabolism, suggesting that caffeine plays a role in this association. Caffeine is a central nervous system stimulant, so your daily java jolts can rev your metabolism 5 to 8%—about 98 to 174 calories a day. A "slow metabolism" is more accurately described as a low BMR.
