18 Surprising Reasons You Should Increase Dopamine (and 45 ways to increase dopamine)

Without dopamine, we wouldn’t be able to feel driven and motivated. Dopamine is also very important for our emotional responses, movement, pain, and the brain’s reward center. Many people seek out artificial sources of dopamine, which can lead to addiction. Read this post to learn about dopamine and ways to increase or decrease it.



Dopamine is a neurotransmitter, which is a chemical released by neurons (nerve cells) to send signals to other nerve cells (R).

Many areas of the brain produce dopamine. It is produced in the ventral tegmental area (VTA in the image above) of the midbrain, the substantia nigra pars compacta, and the arcuate nucleus of the hypothalamus (R).

The most important dopamine pathway in the brain controls reward-motivated behavior (R).

Most types of rewards, such as new experiences or accomplishment, can increase dopamine levels in the brain. In addition, most addictive drugs and behavioral addictions can increase dopamine (R).

In addition, dopamine has many other important roles in humans, including movement, memory, attention, learning, sleep, and mood (R).

Dysfunctions of the dopamine system contribute to Parkinson’s disease, schizophrenia, restless legs syndrome, and attention-deficit hyperactivity disorder (ADHD) (R).

The Roles of Dopamine

1) Dopamine is Responsible for Motivation


Dopamine is also known as the “motivation molecule”. It is responsible for intrinsic motivation, and provides the motivational/internal drive to do things (R, R, R).

We do things because we find them rewarding. Dopamine is responsible for reward-seeking behavior (R, R). It is the reward signal in the brain.

Activation of dopamine neurons results in good feeling/reward, while inactivation causes aversion (R, R).

In animal experiments, high, moderate and low concentrations of dopamine induce euphoric, seeking and aversive states, respectively (R).

Dopaminergic activity increases exploration (R). And curiosity and interest are important components of intrinsic motivation (R).

Across different mammalian species, there is linkage between dopamine and the positive experiences associated with exploration, new learning and interest in one’s environment (R).

People often experience intrinsically motivated flow states in their daily activities have greater dopamine D2-receptor levels in specific brain regions (R).

On the other hand, low levels of dopamine make people and animals less likely to work for things. Dopamine blockade severely impairs effortful actions to obtain rewards (R).

2) Dopamine Increases the Anticipation of Pleasure

When exposed to a rewarding stimulus, the brain responds by releasing more dopamine (R).

During these pleasurable situations, dopamine is released and stimulates one to seek out the pleasurable activity (R).

Pleasurable experiences such as sex, food, games or even drug abuse can increase dopamine release (R).

This brain reward system promotes survival of the species by rewarding behaviors necessary for continued survival such as seeking food, reproduction, shelter, and drink, etc.  These activities that are essential to species survival and activate this pathway are associated with ‘feeling good’ (R).

Histamine, acting on histamine H1 receptors, can potentiate dopamine receptors to become more sensitive to dopamine (R). Therefore, people with higher histamine levels or stronger H1 receptor activation may feel more pleasure from dopamine.

Dopamine does not mediate pleasure. It is known that the loss of dopamine does not affect the feeling of pleasure in humans or animals (R).

What it does is enhances the expectation of pleasure in humans (R).

This molecule is responsible for “wanting” something but not “liking” something (the hedonic effects of “liking” are mediated by opioids) (R, R, R).

3) Dopamine Helps with Memory and Learning


Dopamine activity in the brain plays a big part in memory and learning (R). It is essential for long-term memory storage and retrieval (R).

Dopamine signals important events. It helps you remember events that have motivational significance. This ensures that memories are relevant and accessible for future behavior (R).

Dopamine also plays an essential role in working memory. Working memory is the capacity to use information from short-term memory and use it to guide your own actions. Dopamine promotes nerve cell activity involved in working memory (R).

Serotonin also works with dopamine during memory formation. Activation of serotonin receptors can increase dopamine release in parts of the brain that are involved in cognition and memory formation, i.e. the prefrontal cortex and hippocampus) (R).

Dopamine release causes an individual to be motivated by certain stimuli. It can control and teach the individual different behaviors. Thus, it plays an important part during reward-driven learning (R).

4) Dopamine Increases Your Attention and Focus

Dopamine has a role in focus and attention (R).

Dopamine dysfunction in frontal lobes can cause a decline in attention or even attention deficit disorders (R).

Moderate levels of dopamine (not too high or too low) improve the capacity of individuals to switch attention efficiently between tasks (R). Furthermore, moderate levels of dopamine direct attention more efficiently to stimuli that are relevant to ongoing tasks (R).

5) Dopamine Makes You More Social and Extroverted

Dopamine and its pathways are associated with extroversion (R).

Higher dopamine levels in 16 male patients were associated with an extroverted personality (R).

People with genes that cause increase dopamine

The presence of the “C” allele in this SNP the DRD4 gene (in carriers of the COMT A/A genotype) showed high levels of extroversion and hypomania (R, R).  The SNP is associated with more DRD4 receptors and therefore results in higher dopamine activity.

The “A” allele of this SNP in the DRD2 gene has been associated with a one-third reduction in D2-receptors.  These people had significantly higher scores on trait Extroversion. Such individuals may be characterized by relatively higher Dopamine activity (as a result of receptor down-regulation) (R).

6) Dopamine Helps Form Romantic Attachments


Intense romantic love is associated with the dopamine reward system (R, R). Dopamine is released through sex, touch and orgasm, and plays a major role in formation and maintenance of pair bonds (R).

When human subjects viewed photographs of people with whom they were in love, their brain activity patterns looked remarkably similar to those observed after cocaine infusions, or monetary reward, with heavy activation of dopamine-rich regions in the brain (R, R, R, R).

Prairie voles are mate for life. However, injecting prairie voles with dopamine blockers causes them to lose their monogamous tendencies—they fail to show any partner preference (R).

We know now that romantic bonding in humans is a result of the crosstalk vetween oxytocin, the “love molecule”, and dopamine (R).

The dysfunction of dopaminergic systems that become activated when we see people we love can be associated with autism (R, R).

7) Dopamine Helps Establish Maternal Behavior

Maternal behavior is the result of a highly-motivated brain, that allows the female to flexibly adapt her caring activities to different situations (R).

Dopamine, along with oxytocin, plays a key role in maternal behavior (R).

Increases in dopamine levels are observed during nursing bouts (R).

Injections of dopamine receptor blockers result in deficits in maternal behavior in rats. On the other hand, improvements in dopaminergic signaling positively impact the deficits observed in maternal behaviors (R).

8) Dopamine Can Decrease Inflammation Due to Th1 and Th17 Dominance

Dopamine is shown to interact with the immune system. Treatment with dopamine can decrease inflammation and have other therapeutic effects (R).

The Dopamine 3 (D3) and D5 receptors are more inflammatory, while the D1, D2, and D4 receptors are more anti-inflammatory (R).

Although the immune effects are quite complex, overall, dopamine decreases inflammation. It reduces Th1 and Th17 dominance (R).

Low levels of dopamine would stimulate mainly the D3 receptor in T cells, favoring Th1-like responses and T cell activity. Moderate dopamine levels would stimulate the Dopamine D5 receptor as well, inhibiting T cell function. All of these increase inflammation (R).

Overall, higher dopamine levels decrease T cell response and inflammation (R).

DRD1 signaling inhibits the NLRP3 inflammasome. Inflammasomes are immune system receptors and sensors that induce inflammation in response to infectious microbes. DRD1 activation can potentially treat NLRP3-driven inflammation and diseases (R).

Higher levels of dopamine can help alleviate Rheumatoid Arthritis, IBD, and Lupus (R).

9) Dopamine Receptors Influence the Sleep Cycle


Dopamine and its receptors play a part in controlling the sleep-wake cycle (R).

Mainly, dopamine can help keep you awake and alert.

Dopamine D4 receptor combines with adrenaline receptors to block adrenergic receptor signaling and melatonin synthesis that is usually induced by the noradrenaline on the adrenergic receptor (R).

On the other hand, mice depleted of dopamine have a complete suppression of REM sleep. Activating dopamine receptors helped recover REM sleep. This indicates that dopamine is vital in regulating sleep (R).

Dopamine D1 receptor (DRD1) activation induces arousal and wakefulness. It also reduces slow-wave sleep and REM sleep (R).

DRD2 activation causes different effects depending on the levels of activation. Low levels of activation reduce wakefulness and increase Slow Wave (deep) and REM sleep. On the other hand, high DRD2 levels induce the opposite effect (R).

Compounds that block both D1 and D2 receptors reduce wakefulness and increase deep sleep (R).

DRD3 activation induces sleepiness and sleep in laboratory animals as well as humans (R).

Patients suffering from Parkinson’s disease may also have sleep disturbances because they have low dopamine (R).

10) Dopamine Helps Increase Bone Strength

Dopamine has an effect on calcium metabolism and can help increase bone strength (R).

Mice missing the dopamine transporter (SLC6A3) gene have a weaker bone strength and less bone mass compared to normal mice (R).

Additionally, male patients with excess levels of prolactin due to low dopamine can have a low bone mineral density (BMD). Dopamine treatment increased their BMD and strengthened their bones (R).

Also, dopamine treatment increased bone cell formation and mineralization in mouse cell culture (R).

11) Dopamine Increases Creativity


Studies show that human creativity relies on dopamine. However, creativity is complex, and different aspects of creativity are affected by different dopaminergic systems (R).

Dopamine has first been associated with creativity after an observation that people with Parkinson’s develop artistic-like tendencies on dopaminergic therapy (R, R).

A study shows that Parkinson’s disease patients treated with dopaminergic drugs show enhanced verbal and visual creativity (R).

Dopamine is involved in cognitive flexibility – one of the main components of creativity and creative thinking. Dopamine is also responsible for openness to new experiences, another factor associated with creativity (R).

In healthy people, creativity was positively correlated with grey matter in dopamine-rich regions of the brain (R).

Various aspects of creativity were reported to relate to SNPs in COMT, DRD2 and DRD4 genes (R, R).

A SNP in DRD2, rs1800497 T, is associated with reduced dopamine binding sites in the brain. This allele was related to higher verbal creativity (R).

A polymorphism in DRD4 has a complex relationship with creativity. DRD4-7R is associated with impaired flexibility associated with low creativity. On the other hand, this allele is associated with higher novelty-seeking associated with greater flexibility and creativity (R).

Finally, the food we eat may affect the way we think (R). Creativity in convergent (“deep”)-thinking tasks is promoted by the food supplement L-Tyrosine -a biochemical precursor of dopamine (R).

12) Dopamine Speeds up Our Internal Clock


Our sense of time is far from constant. For instance, time flies when we are having fun, and it slows to a trickle when we are bored (R).

Brain dopamine system regulates our internal clock speed (R, R). Dopamine adjusts both time perception, in the seconds-to minutes range, and the timing of motor acts (movement) (R, R).

Increasing dopamine (by stimulants such as amphetamine) increases clock speed, while dopamine receptor blockers (such as haloperidol) decrease clock speed (R, R).

Substances such as nicotine and marijuana also speed up the internal clock (R, R).

The ‘internal clock’, is abnormally slow in Parkinson’s disease (R).

Time estimation is also impaired in patients with schizophrenia (R) or patients with structural damage to certain brain regions, resulting from traumatic brain injury (R).

13) Dopamine Relieves Nausea

The stomach and intestines also have dopamine receptors. Dopamine acts through specific receptors to lower pressure in the gut. Drugs that increase dopamine activity stimulate the intestines to increase movement and function (R).

These drugs can help relieve nausea, vomiting, and even acid reflux (R).

Drugs that block the DRD2 receptor can decrease nausea, perhaps by increasing dopamine activity.

14) Dopamine Inhibits Prolactin

The hypothalamus can release dopamine, which then acts as a hormone inside the brain (R).

Dopamine is the main inhibitor of the prolactin secretion in the anterior pituitary gland (R).

It is important for prolactin hormone levels to be balanced. High prolactin levels (hyperprolactinemia) can cause reproductive problems in both men and women. Dopamine can help maintain healthy levels of prolactin (R).

15) Dopamine Helps Movement

The basal ganglia, which is the largest and most important sources of dopamine in the brain, controls movement (R). In order for the basal ganglia to function well, it requires sufficient dopamine release at the input nuclei (R).

16) Normal Dopamine Levels Help Prevent Parkinson’s Disease

Dopamine is responsible for the communication between two regions in the brain, which is the substantia nigra and the corpus striatum. This is critical in producing smooth, purposeful movement. Loss of dopamine in this circuit results in impaired movement (R).

The nerve cells in this circuit produce dopamine. Parkinson’s disease occurs when these nerve cells become impaired and/or die (R).

When approximately 60 to 80% of the dopamine-producing cells are damaged and do not produce enough dopamine, the motor symptoms of Parkinson’s disease appear (R).

Low dopamine levels contribute to the painful symptoms that frequently occur in Parkinson’s disease (R).

17) Dopamine Can Prevent Nearsightedness (Myopia)


The biggest risk for nearsightedness in people is the amount of time spent indoors (R).

Scientists can induce myopia in animals by lowering the level of light (R).

The leading hypothesis is that light stimulates the release of dopamine in the retina, and this in turn blocks the elongation of the eye during development (R).

Injecting a dopamine-inhibiting drug called spiperone into chicks’ eyes could abolish the protective effect of bright light (R).

Retinal dopamine is normally ramped up during the day, which helps daytime vision. Researchers now suspect that under dim (typically indoor) lighting, the cycle is disrupted, and this leads to myopia (R).

18) Dopamine Stimulates Sexual Drive

D1/D2 dopamine receptor activators help treat erectile dysfunction, which demonstrates the participation of the dopamine system in the control of sexual drive (R).

Drugs that stimulate the activation of hypothalamic dopamine may be effective in stimulating sexual desire in animals and humans (R).

Dopamine increased the response to sexual stimulation in men, but not women (R).

Dopamine can decrease prolactin, which can inhibit sexual drive (R).

Cons of Dopamine

1) Excess Dopamine May Cause Schizophrenia

Schizophrenia is characterized by negative symptoms such as apathy and poor social functioning, and positive symptoms, such as hallucinations and delusions (R).

The dopamine hypothesis proposes that schizophrenia is caused by excessive production of dopamine in the brain (R).

Studies support the idea that an overactive dopamine system may result in schizophrenia. Medications that block dopamine receptors, specifically D2 receptors, reduce schizophrenia symptoms (R).

Additionally, some evidence suggests that the negative symptoms and some of the cognitive deficits in schizophrenia may be related to lower prefrontal cortex function. This, in turn, may be associated with decreased dopamine activity. However, there is only indirect evidence to support this (R).

Thus, some features of negative schizophrenia (social withdrawal, apathy, and the inability to feel pleasure) are thought to be related to low dopamine levels in certain areas of the brain (R).

2) Dopamine Can Fuel Addiction


Drugs such as cocaine, nicotine, and amphetamines act to increase dopamine in the striatum. This can lead to drug addiction (R).

The reinforcing effects of these drugs don’t only come about because of increased dopamine, but also because of the fast rate that dopamine increases. The faster the increase, the more intense the reinforcing effects (R). This can damage or reduce the dopamine receptors over a period of time, causing increased needs for the drugs.

Long-term drug use seems to be associated with decreased dopamine function. The reductions in D2 dopamine receptors and dopamine release in the striatum in addicted subjects supports this hypothesis (R).

3) Dopamine Affects Weight

Dopamine, along with serotonin, opioids, cannabinoids, orexin, leptin and ghrelin, mediates the rewarding effects of food (R).

It is associated with the desire to eat the food and with the conditioning of food cues. It is also involved with the motivation to perform the behaviors necessary to buy, prepare, and consume the food (R).

So, dopamine will cause you to desire food when you simply smell it. It causes you to ‘want’ food as opposed to just ‘liking’ the food (R).

Because dopamine is released when someone eats food, this could contribute to overeating. They will seek to increase their dopamine levels with food consumption which can cause weight gain and obesity (R), especially in people with low dopamine levels.

Dopamine is also associated with the motivation to alleviate negative emotion through eating. In both normal-weight and obese participants, emotional eating was associated with higher  dopamine receptor D2R binding (R).

4) High Levels of Dopamine Can Cause Aggression

High levels of dopamine can cause aggression. Blocking dopamine receptors decreases aggression in people (R).

5) Dopamine Decreases Empathy and Cooperation

Some observe that our modern society is a dopaminergic society. It is an extremely goal-oriented, fast-paced, and even manic society. Dopamine is known to increase activity levels, speed up our internal clocks, and create a preference for novel over unchanging environments (R).

On the other hand, high-dopamine individuals lack empathy and exhibit a more masculine behavioral style: conquest, competition, and aggression over nurturance and communality (R).

Increasing dopamine, decreases empathy. In human subjects, dopamine precursor levodopa increased the decisions to inflict pain on oneself and others for financial gain (R).

In a different study, people with the COMT 158Val variant, resulting in lower dopamine levels, showed higher cooperation compared to 158Met people with higher dopamine. Carriers of two 158Val variants (lower dopamine) are considered to be more helpful and empathic (R).

6) Dopamine Can Cause Constipation

While dopamine can help with gut function, it can also cause constipation (R).

Dopaminergic medications in Parkinson’s disease can increase constipation risk (R).

    Wild green oat extract works at increasing dopamine because of an active ingredient, the flavone isovitexin. But this same flavone is found in passion flower which has many advantages over green oat extract including price. Passion flower also fights opiate and nicotine addictions, asthma, is an anti-aromatase agent and can restore lost libido. It can reduce anxiety and promote sleep. it is an effective antioxidant, anticoagulant and monoamine oxidase inhibitor. It may relieve gastrointestinal distress and premenstrual syndrome, is antiinflammatory and can help lower blood pressure. Topical applications of passion flower can sooth irritated skin, including hemorrhoids. It may have many other beneficial uses but I haven’t done a complete literature search of it. Perhaps this will be a topic of a future article on this site.

    • Jon

      which passion flower you took, sir, because from all the ones i took, none of them did all the things you mention here. must be some new magical one, found in some exotic place

  2. Ken

    One of my supplement suppliers has recently announced a dopamine supplement. How do you feel about supplementing with dopamine directly?

  3. Issie


    So for those with MCAS who block H1, H2 And some H3 – since this has a part in pathways – makes sense that blocking those things could cause more issues with brain fog and memory issues. Trying to balance out dopamine levels and deal with other chronic issues a real challenge. I know calcium channels play a part in this. One of the mess for MCAS in addition to being a mast cell stabilizer is also a mild calcium channel blocker. Any thoughts?
