Caffeine And Dopamine - Benefits And Harm

Caffeine and dopamine, both of these substances are CNS (Central Nervous System) stimulants. Any specific effects of dopamine on increased caffeine intake?

Drinking coffee or other caffeinated beverages can induce the release of catecholamine neurotransmitters, as can dopamine and adrenaline (epinephrine).

Caffeine has been studied for a long time to determine its benefits and harms to our body. Health experts say caffeine can cause negative effects such as stress, anxiety, cravings for food and sleep. But also, caffeine can provide benefits such as short-term memory improvement, attention concentration improvement, mood improvement, energy.

While caffeine can provide benefits in some ways, it can also reduce long-term dopamine depletion and reduce the sensitivity of dopamine receptors in your brain.


What Is Caffeine?

Scientifically, caffeine is classified as a purine methylxanthine alkaloid. It is a CNS stimulant commonly found in coffee or tea forms.

The taste of caffeine is a bit bitter. Caffeine is the most commonly consumed substance in the world, many people start the morning with a cup of coffee or tea, they immediately get the appropriate portion of caffeine. It is estimated that approximately 90% of adults in North America consume caffeine products every day.

Caffeine works on several principles of the mechanism. In particular, it stimulates certain autonomic sites in the nervous system and inhibits adenosine activity.

,,Adenosine plays an important role in biochemical processes by participating in energy (ATP, ADP), signal (cAMP) transfer reactions. "

Caffeine also promotes better alertness, better energy levels and concentration. Caffeine also has other effects on the body, such as increasing physical efficiency, reducing sensitivity to pain, promoting metabolism.

Caffeine can also act as a mood enhancer, improving overall well-being shortly after consumption. This is due to the fact that caffeine intake stimulates the release of the neurotransmitter dopamine in the brain.


Caffeine and Adenosine

Caffeine inhibits the effects of adenosine, adenosine is a neuromodulator and is involved in prevention, due to excitation of the nervous system.

Cyclic adenosine monophosphate (cAMP) is vital for efficient signal transduction. Adenosine is also a potent vasodilator that can help blood flow to the body’s organs and tissues.

Adenosine is synthesized inside the brain, where it is used for certain purposes.

Adenosine opens blood vessels during sleep so that the body can treat itself when needed, at which time the process of delivering oxygen and other nutrients to the tissues is activated.


Caffeine and Dopamine Levels

Dopamine is a natural neurotransmitter that regulates sleep, libido, emotional states, motivation, movement, and pleasure.

Dopamine is a chemical in the brain that is released when you are in a pleasant state, and this is what happens when you consume caffeine.

So what to do with adenosine when caffeine and dopamine go together? Due to the molecular structure itself, caffeine and adenosine may bind slightly to receptors in the brain.

When caffeine binds to adenosine receptors, caffeine begins to have an inhibitory effect upon binding to adenosine receptors.

The result: increased stimulating effect and stronger arousal for your central nervous system. As a non-direct result of dopamine, it is released, resulting in improved mood, improved concentration.

Caffeine can also slow dopamine reabsorption. Although far from strong, caffeine affects dopamine reabsorption in the same way as cocaine or heroin.


How Caffeine Depletes Dopamine Stocks

Caffeine consumption can also affect the depletion of dopamine stores, which can have serious consequences for the condition of your body. As a result of all this - a bad mood, a sharp decline in productivity and motivation. You may also experience what athletes call a “crash”.

Caffeine can also cause narrowing of internal blood vessels in your brain. This is because caffeine blocks the effects of adenosine, which dilates blood vessels.

When your pituitary gland feels a narrowing of the blood vessels, your body begins to produce adrenaline accordingly.

Adrenaline is a “fly or mask” chemical that introduces us to the emergency-protective mode of the body. When adrenaline is released, it can have the following consequences:


  • Activates energy synthesis in the liver
  • Blood flow in the extremities slows down
  • Increases blood delivery to the muscles
  • Digestion slows down
  • Blood pressure rises
  • Breathing intensifies
  • Heart rate increases


Thus, caffeine promotes these effects through “stimulating” adrenaline release. Adrenaline is a direct precursor of dopamine.

In this case, dopamine is forcibly converted to adrenaline. Caffeine acts directly to ‘suck up’ dopamine stores, especially with chronic use.


Caffeine Addiction and Abstinence

Many people experience symptoms of addiction related to caffeine and dopamine. When you drink a cup of strong coffee, especially if you feel tired, then you may experience some symptoms of caffeine overdose.

First, adenosine is inhibited and alertness is increased. Adenosine is then activated and released to improve metabolism. Finally, dopamine reabsorption is inhibited, as a result of which you may feel an elevated mood and a pleasant feeling.

For a short time, a portion of caffeine can be really helpful, improving cognitive function, mental and physical energy levels.

However, a repeated dose of caffeine can cause really side effects. The half-life of caffeine is approximately six hours. After that, the stimulating effect disappears and the caffeine compounds are eliminated from the body, then sensations such as; fatigue, depression, irritability, anxiety.

To prevent these unpleasant symptoms, many people consume even more caffeine. This again leads to CNS activity, dopamine stimulation and the release of catechlomin hormones.

Muscles ‘strengthen’, breathing shortens, heart beats faster. Nervousness, anxiety, possibly hyperactivity. Long-term exposure may affect sleep quality and neurotransmitter homeostasis.

Finally, many experience these unpleasant withdrawal syndromes when they stop taking caffeine. In part, this may be related to dopamine receptors that have developed tolerance.



Caffeine can directly affect dopamine levels in the brain. If you take supplements that contain caffeine in the short term can increase dopamirgetic activity, long-term use can completely unbalance the stores of this hormone and cause tolerance and withdrawal syndromes.

Caffeine, nicotine, cocaine, sugar, processed foods, industrial toxins, a sedentary lifestyle, and uncontrolled stress will always have a negative impact on your dopamine stores.

It is necessary to eat products rich in amino acids L-tyrosine ir phenylaninowhich will help balance dopamine levels. Supplements such as L-Tyrosine can also help increase dopamine stores in the brain in the short term.

**We recommend try a natural food supplement Dopavite Original - Food to raise dopamine levels in the brain and improve mood.

It is important not to abuse caffeine. Excessive portions can cause severe side effects or even death (in rare cases). Most health professionals recommend consuming no more than two cups of coffee a day.

Caffeine and dopa supplements may interact with each other, medications, or supplements you are taking. It is recommended that you talk to your doctor before taking dopamine boosters to find out about possible side effects and the safety of these supplements.
