What is Caffeine?

Caffeine is a central nervous system stimulant of the methylxanthine class. It is the world’s most consumed psychoactive drug. It actually goes by a few names like Coffee extract, Tea extract, or 1, 3, 7-Trimethylxanthine. (1)

But unlike many other psychoactive substances, caffeine is legal and generally very safe. However, it is currently on WADA’s monitoring list. This means, while caffeine is not prohibited, WADA is monitoring it in case it becomes an anti-doping issue in the future. Keep in mind that the amount of caffeine you are allowed to consume as an athlete may vary per sport. (2)

How Does Caffeine Work?

Caffeine is soluble in water and lipids (fats), and easily crosses the blood–brain barrier. When ingested, caffeine binds to adenosine receptors located in the central and peripheral nervous systems. After caffeine connects to these receptors, a blockage of adenosine forms which causes the sleep-promoting effects of adenosine to stop. This results in neurons speeding up instead of slowing down. (3

Because caffeine is easily absorbed in the body, about 99% of caffeine can be absorbed within 45 minutes from ingestion. In which, peak plasma concentration can occur anywhere from 15 and 120 minutes after oral ingestion. But, it can remain in the blood anywhere from 1.5 to 9.5 hours (depending on various factors) and has a half-life of about 5 hours in adults. (4)

How to Take Caffeine:

Caffeine dosages will and should vary. In the U.S. , the average adult consumes around 135-165mg of caffeine daily. However, if you’re not sure of your tolerance level to caffeine, you may want to start with lower dosages. Then, when you feel comfortable, you can increase your dosage. While the U.S. Food and Drug Administration (FDA) considers 400mg a safe amount of caffeine for healthy adults to consume daily, some individuals may be more sensitive to the effects of caffeine than others. So it’s important to assess your tolerance before taking large doses. (5)

Section Divider: Tolerance

Tolerance & Toxicity:

Too much of anything is too much and this can be especially true for caffeine. Caffeine toxicity can occur at intakes of 1.2 grams or more in a singular dosage. In which, toxicity can present with a range of symptoms, including, but not limited to (6):

  • Nervousness
  • Gastrointestinal Disturbances
  • Insomnia
  • Arrhythmia
  • Excitability
  • Inattentiveness
  • Restlessness

How Does Caffeine Tolerance Form?

As we mentioned previously, when caffeine binds to adenosine receptors, an adenosine blockage forms. And with regular consumption of caffeine, the body can respond with increasing the production of adenosine. This increases the chance of adenosine binding to the receptors instead of caffeine. The consequence of this is that the effects of caffeine are reduced and causes you to become tolerant. Because of this, it’s important to cycle off it every now and again. 

You may want to cut back if you’re reaching for a source of caffeine more than 4 times a day. (7)

Or if you’re experiencing side effects such as:

  • Migraine headache
  • Insomnia
  • Nervousness
  • Irritability
  • Restlessness
  • Frequent urination or inability to control urination
  • Stomach upset
  • Fast heartbeat
  • Muscle tremors

Side Effects With Withdrawal:

In addition to becoming tolerant, regular caffeine consumption can form an addition. When taking a break from regular caffeine consumption, you experience withdrawal symptom. These symptoms may include but are not limited to (6):

  • Headaches
  • Irritability
  • Nervousness
  • Nausea
  • Constipation
  • Muscular Tension

Symptoms of withdrawal usually appear about 12-24 hours after someone has stopped consuming caffeine. However, they can last for about one week. It is generally recommended to gradually decrease your caffeine intake to avoid symptoms. (6)

How Does Caffeine Affect My Sleep?

Melatonin is a key hormone in the sleep-wake cycle. The production and release of melatonin in the brain relates to light exposure. When you’re in dim-light, the production of melatonin increases and when you’re in bright-light, it is suppressed. Caffeine can suppress this hormone and thus delay the sleep-wake cycle.(12)

Because the effects of caffeine can last for several hours, it is often recommend to avoid caffeine intake for at least 6 hours prior to sleep.
