How do you know if you have a slow caffeine metabolizer?
Likely, your body is giving you signs that can clue you into where you fall on the great coffee divide. Slow metabolizers can get jittery and stay wired up to nine hours after drinking caffeine, according to Precision Nutrition. Meanwhile, fast metabolizers simply feel more energetic and alert for a couple hours.
What does it mean to be a slow metabolizer of caffeine?
If you are a Slow Metabolizer then your genetic makeup indicates you process caffeine at a slower rate and, as a result, caffeine may have longer-lasting stimulant effects. Slow metabolizers may experience negative side effects of caffeine consumption to a higher degree such as insomnia, anxiety, and upset stomach.
Which gene is associated with caffeine metabolism?
CYP1A2 produces a liver enzyme that metabolizes roughly 95 percent of all ingested caffeine. AHR controls how much of that enzyme you produce. Together, these genes control how much caffeine circulates in your bloodstream, and for how long.
What does the CYP1A2 gene do?
CYP1A2 functions primarily to metabolize several antipsychotic medications and theophylline. Environmental and genetic factors are shown to influence the activity of CYP1A2. These can account for up to a 60-fold difference in activity.
Do people metabolise caffeine differently?
Some will metabolise caffeine quickly, while others will metabolise it more slowly; some will show greater sensitivity to the stimulating effects of caffeine, while others needs higher amounts to feel an effect1.
How can you metabolize caffeine faster?
Here are a few ways to get rid of caffeine jitters quickly:
- Water. An effective way to get rid of your jitters is to flush out your system with water.
- Exercise. You just crossed the caffeine line, which probably means you can’t sit still.
- Wait it out.
- Sip on some herbal tea.
- Amp up your Vitamin C game.
What does it mean to be a slow metabolizer?
Definition of ‘slow metabolizer’ A slow metabolizer is someone whose body is slow to break down, absorb, or use a particular substance. Some patients, known as slow metabolizers, metabolize drugs too slowly. The patient was a slow metabolizer and did not absorb the drug as quickly as expected.
What is caffeine metabolism?
Metabolism. Caffeine is almost completely metabolized with 3\% or less being excreted unchanged in urine [3,6]. The main route of metabolism in humans (70–80\%) is through N-3-demethylation to paraxanthine also known as 1,7-dimethylxanthine or 17X [3,6,7] (see Fig. 1).
How does caffeine affect metabolic rate?
The rate at which you burn calories at rest is called resting metabolic rate (RMR). The higher your metabolic rate, the easier it is for you to lose weight and the more you can eat without gaining weight. Studies show that caffeine can increase RMR by 3–11\%, with larger doses having a greater effect ( 11 , 12 ).
Does caffeine induce CYP1A2?
Results from rat studies have shown that caffeine is an inducer of CYP1A2, the enzyme responsible for caffeine’s metabolism. This suggests that CYP1A2 induction by caffeine may be in part responsible for caffeine tolerance.
How is caffeine metabolized?
Caffeine is processed or metabolized in the liver by the cytochrome P450 oxidase enzyme system and broken down into three metabolic dimethylxanthines. These include: Paraxanthine (forms 84\%), which breaks down fats and increases blood levels of glycerol and fats.
How do you metabolize caffeine faster?
Is it normal to be a slow metabolizer of caffeine?
Some people have one slow and one fast copy of the variant and are said to be moderately tolerant to caffeine. However, those individuals who have two copies of the slow variant are slow metabolizers of caffeine and are said to be poorly tolerant of it. How does caffeine affect your metabolism?
What are the genes involved in caffeine metabolism?
And for those of you who are also interested in the technical aspects, the relevant genes are the AHR and CYP1A2 genes. Apparently, there is an enzyme in the liver that metabolizes caffeine, p450 1A2 (CYP1A2) and it works differently in different people.
Do slow caffeine metabolizers increase heart attack risk?
This means that slow metabolizers keep caffeine longer in their systems, and this may cause myocardial infarction. My takeaway from all this was that for slow caffeine metabolizers like myself, caffeine consumption may increase my risk for heart attack.
Should you get a genetic test for caffeine tolerance?
Genetic tests can help identify such parameters. 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. Caffeine tolerance in an individual is gene deep.
