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.
How do you know if you are 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.
Can some people not metabolize caffeine?
People with anxiety or panic disorder may experience a worsening of their symptoms after consuming caffeine. Some researchers suggest that the cause of caffeine sensitivity may occur at the receptor level, where caffeine binds, or at the level of metabolism. For example, some people are slow metabolizers of caffeine.
What does it mean when you metabolize caffeine fast?
Here’s what this whole caffeine metabolism spectrum is all about: “’Fast metabolizers’ refers to those that have a low sensitivity to caffeine, while ‘slow metabolizers’ have a high sensitivity,” says Gillespie.
Do athletes metabolize caffeine faster?
On average, caffeine makes athletes faster – but for half of us, its effects may be muted or perhaps even counterproductive.
What does it mean to be a 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.
How do you metabolize caffeine better?
Eat fiber-rich food. Eating may slow the release of caffeine into your bloodstream. Opt for slow-digesting, fiber-rich foods, such as whole grains, beans, lentils, starchy vegetables, nuts, and seeds ( 1 ).
Why is caffeine making me sleepy?
Caffeine can block the effects of adenosine, which is what makes you feel alert after your morning cup of joe. However, once the caffeine wears off, your body may experience a buildup of adenosine that hits you all at once, which is why coffee can make you feel tired.
Can you build an immunity to caffeine?
As you consume the same amount of caffeine on a daily basis, your body develops a tolerance to it. Other factors like your age, body mass, and overall health can determine your tolerance to caffeine, too. If you want to decrease the amount of caffeine you take, it’s best to decrease your consumption slowly.
Does caffeine affect people with ADHD?
Some studies have found that caffeine can boost concentration for people with ADHD. Since it’s a stimulant drug, it mimics some of the effects of stronger stimulants used to treat ADHD, such as amphetamine medications. However, caffeine alone is less effective than prescription medications.
What does it mean to be a fast metabolizer?
People who inherit two copies of the “fast” variant – one from each parent – are generally referred to as fast metabolizers. Their bodies metabolize caffeine about four times more quickly than people who inherit one or more copies of the slow variant of the gene.
What does it mean to be a rapid metabolizer?
s, Your result puts you in the rapid metabolizer group.
In people who are rapid metabolizers, the CYP2C19 enzyme has high activity. People who are rapid metabolizers break down some medicines quickly and may need different doses or a different medicine. About 29% of our patients are rapid metabolizers.
How does CYP1A2 metabolize caffeine?
Caffeine is almost completely metabolized in the body by cytochrome P450 1A2 (CYP1A2). This enzyme accounts for the metabolism of caffeine to its principal metabolite, paraxanthine . In vivo, CYP1A2 activity exhibits a significant degree of inter-individual variation (see  for review).

What happens when you metabolize caffeine?
Levels of caffeine peak in the blood within about 15–45 minutes of consumption. They are then quickly metabolized by the liver. Most people notice the strongest effects during this time, and many report feeling jittery, needing to urinate, and having sudden bursts of energy.
