What Is Dopamine?
Dopamine is the compound that fuels our drive and motivation. It increases attention, improves cognitive function, and stimulates our creativity. It makes us more social and extroverted and helps us form romantic and parental bonds. However, dopamine, when too high, can also have its drawbacks.
What Does Dopamine Do?
The most important dopamine pathway in the brain controls reward-motivated behavior.
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.
In addition, dopamine has many other important roles in humans, including movement, memory, attention, learning, sleep, and mood.
Dysfunctions of the dopamine system contribute to Parkinson’s disease, schizophrenia, restless legs syndrome, and attention-deficit hyperactivity disorder (ADHD).
The Dopamine Diet: An Ideal Diet to Increase Dopamine
The following diet will be optimal for increasing dopamine:
- Protein-rich diet for tyrosine and phenylalanine
- Seafood for DHA
- Lots of Vegetables for magnesium, soluble fiber, and folate
- Olive oil and avocados – for monounsaturated fats
- Green tea for theanine and caffeine
- Animal foods or Cholesterol-rich foods for pregnenolone and also iron
- Spices such as turmeric and oregano
- Bananas
- Low sugar diet
Our bodies produce dopamine from the amino acid tyrosine. In turn, tyrosine can be produced from phenylalanine.
Bananas especially contain high dopamine and L-dopa levels [5, 6].
Bananas especially contain high dopamine and L-dopa levels [5, 6].
Saturated fats can suppress dopamine. Equivalent intake of monounsaturated fats (from olive oil) protects against dopamine decreasing [7].
Green tea increases dopamine in rats [8, 9], including its constituents Theanine and Caffeine.
Caffeine’s performance-enhancing effects are accomplished via dopamine. Caffeine maintains a higher dopamine concentration especially in those brain areas linked with attention [10].
You want to consume cholesterol-rich foods because cholesterol is a precursor to Pregnenolone, which increases dopamine in animals [11, 12].Saturated fats can suppress dopamine. Equivalent intake of monounsaturated fats (from olive oil) protects against dopamine decreasing.

You want to consume cholesterol-rich foods because cholesterol is a precursor to Pregnenolone, which increases dopamine in animals.
Magnesium has antidepressant effects that can partially be tied to increasing dopamine activity in the brain [13].
Curcumin, found in the spice turmeric, increases dopamine concentration in the brain [14, 15, 16], by inhibiting MAO-mediated dopamine break down [17].
Resistant starch is a type of soluble fiber that increases butyrate. Butyrate may increase dopamine levels [18, 19].
Folate is needed for the production of dopamine (and serotonin). When your body is low in folate, it cannot produce dopamine and other monoamines efficiently, which may result in depression [20, 21].
Nutritional or brewer’s yeast is rich in uridine. Uridine-5′-monophosphate increases dopamine levels in the rat brain [22].
Seafood, which contains DHA, can increase dopamine levels in the brain [23, 24, 25].
Oregano increases dopamine levels by decreasing dopamine break down and reuptake [26].
Both tyrosine and phenylalanine are found in protein-rich foods [27]:
- Chicken and Turkey
- Fish
- Almonds
- Avocados
- Bananas
- Pumpkin and Sesame seeds
- Dairy: Milk, Cheese, Yogurt, Cottage cheese
- Legumes: Soy, Lima beans, Peanuts
Lifestyle to Increase Dopamine
1) Sun/Being outside/Bright Light increases dopamine
Bright light can improve our mood. This may partially be due to dopamine.
A study shows that light may increase dopamine, and thereby improve mood in women with mild seasonal mood disorder [28].
Light also stimulates the release of dopamine in the retina, and this is beneficial for maintaining good vision [29].
2) Exercise
Exercise increases dopamine [30, 31].
A study in women showed that exercise decreases COMT activity, thereby increasing dopamine in women (in the prefrontal cortex) [32]. COMT is the enzyme that breaks down dopamine.
3) Meditation
Meditation increases dopamine release [33, 34].
However, the effects seem to be transient unless meditation is done regularly.
A study shows that long-term meditation practice is needed to induce stable changes in baseline dopamine (striatum) [35].
4) Yoga
3 months of practicing yogaincreased dopamine levels in men (in blood/circulating levels) [36].
The study revealed that yogic practices might help in the prevention of age-related degeneration….in healthy males.
5) Touch
Pleasurable physical contact can increase dopamine.
In rats, it was shown that stroking increases dopamine release (nucleus accumbens) [37].
Tickling, as a form of play behavior in adolescent rats, also increases dopamine release (nucleus accumbens) [38].
In early life, stimulation from touching improves spatial working memory in rats, possibly by improving dopamine function [39].
6) Massage therapy increases dopamine
Massage therapy increases dopamine, with a 31% increase of urinary dopamine in people [40].
Massage increased dopamine levels in pregnant women with depression [41] and in adolescents with bulimia [42].
7) Music
Parts of the brain release dopamine when listening to pleasurable music (striatum, nucleus accumbens) [43, 44, 45, 46].
Not just listening, but creating and performing music also produce dopamine [47].
Food to Increase Dopamine
8) Tyrosine- and phenylalanine-rich food
Our bodies produce dopamine from the amino acid tyrosine. In turn, tyrosine can be produced from phenylalanine [4]. Both tyrosine and phenylalanine are found in protein-rich foods [27]: chicken, turkey, fish, peanuts, almonds, avocados, bananas, milk, cheese, yogurt, cottage cheese, lima beans, pumpkin seeds, sesame seeds, and soy.
Bananas especially contain high dopamine and L-dopa levels [5, 6].
9) Unsaturated fat
Saturated fats can suppress dopamine. Equivalent intake of monounsaturated fats protects against dopamine decreasing [7].
Supplements That Increase Dopamine
10) Tyrosine
Tyrosine supplementation increases dopamine levels in the brain [48, 49, 50].
A study shows that tyrosine supplementation effectively enhances cognitive performance, particularly in short-term stressful and/or cognitively demanding situations when dopamine is temporarily depleted [51, 48].
11) Green Tea
Green tea increases dopamine in rats (in blood, stress model) [8, 9].
Theanine, one of the major amino acid components in green tea, increases dopamine in animals [52, 53, 54].
12) Caffeine
Caffeine increases dopamine release (striatum, nucleus accumbens) [55, 56].
Caffeine’s performance-enhancing effects are accomplished via dopamine. Caffeine maintains a higher dopamine concentration especially in those brain areas linked with attention [10].
13) Pregnenolone
Pregnenolone sulfate increases dopamine in animals (striatum, nucleus accumbens) [11, 12].
14) Magnesium
Magnesium has antidepressant effects that can partially be tied to increasing dopamine activity in the brain [13].
15) St. John’s Wort
A number of studies have shown that St. John’s Wort, an herbal anti-depressant, increases dopamine content in the brain (nucleus accumbens, striatum) [57, 58, 59, 60, 61].
16) Gingko
Gingko biloba increases dopamine and dopamine neuron activity (PVN, VTA, Nucleus Accumbens) [62, 63, 64]. This increase in dopamine may partially explain the improvement of cognitive function observed with Gingko supplementation.
17) Curcumin
Curcumin increases dopamine concentration in the brain [14, 15, 16], by inhibiting MAO-mediated dopamine break down [17].
18) Butyrate
Butyrate may increase dopamine levels in animals in response to toxic injuries (striatum) [18, 19]. You can get butyrate in the diet by consuming soluble fibers found in fruits and vegetables or ghee.
19) Folate
Folate is found in leafy greens/vegetables and is needed for the production/synthesis of dopamine (and serotonin). When your body is low in folate, it cannot produce dopamine and other neurotransmitters (monoamines) efficiently, which may result in depression [20, 21].
20) Huperzine A
Huperzine A is a substance that is known to increase acetylcholine, but it also increases dopamine levels 129% above baseline in rats (cortex) [65].
This substance may help with treating drug addiction [66].
21) SAM-e
S-Adenosyl-l-methionine (SAM-e) is an over-the-counter dietary supplement commonly used to treat depression. SAMe helps in the production of dopamine and other monoamines, causing elevations in dopamine levels [67].
22) Shilajit
Shilajit is a naturally occurring biomass found in the Himalayas. In traditional Indian medical practice to be useful in the treatment of nervous disorders, epilepsy and as an antistress agent.
Shilajit increases the levels of neuronal dopamine in the brain, which has an anxiety suppressing action [68].
23) Uridine
Uridine-5′-monophosphate increases dopamine levels in the rat brain when the neurons are activated (striatum) [22]. Uridine is found very concentrated in nutritional and brewer’s yeast, meat and fish.
24) Fish Oil
Seafood/Fish Oil/DHA can increase dopamine levels in the brain in rats (striatum). Dopamine levels were also 40% greater in the frontal cortex of rats fed fish oil. DHA treatment led to an 89% rise in tyrosine-hydroxylase terminals within the striatum in lesioned animals [23, 24, 25].
25) Ginseng
Ginseng components can increase levels of dopamine in the brain and have beneficial effects on attention, cognitive processing, sensorimotor function and auditory reaction time in healthy subjects [69].
However, ginseng can also blunt dopamine release in response to other stimulants such as nicotineand cocaine [70, 71].
26) Danshen
Red sage, also known as danshen (Salvia miltiorrhiza), may increase dopamine in cells (striatum) [72].
27) Resveratrol
Resveratrol can increase dopamine levels in the brain in animals (frontal cortex, striatum). Resveratrol treatment in old rats increased dopamine by 53% (striatum) [73, 74].
28) Oregano
Oregano extract increases dopamine levels by decreasing dopamine break down and reuptake in animals [26].
29) Carvacrol
Carvacrol, present in the essential oil of many plants including oregano and thyme oils, acts as an antidepressant by activating the dopamine system in mice [75].
At low concentrations (what’s in oregano and supplements), carvacrol increases dopamine. However, in high concentrations, it may decrease dopamine levels [76].
30) Clary sage
Clary sage (Salvia sclarea) oil increases dopamine activity in rats, which contribute to its anti-depressant effects [77].
31) Bacopa
Bacopa (Bacopa monnieri) extract can increase dopamine in rats (in the cortex and hippocampus) and have a nootropic effect [78, 79].
32) Mucuna pruriens
Mucuna pruriens has a high concentration of L-Dopa (4 – 7%), which is a precursor of dopamine [80].
Mucuna pruriens, an ayurvedic plant, was shown to increase dopamine in mice [81, 82].
33) Catuaba
The Brazilian medical plant catuaba (Trichilia catigua), increases dopamine release and may have dopamine-mediated antidepressant effects [83].
The herbal product containing this plant, catuama, has similar effects [84].
34) Rosemary
Rosemary (Rosmarinus officinalis) increases brain dopamine levels [85].
35) Kava
Higher doses of kava (Piper methysticum) increase levels of dopamine in rats (nucleus accumbens). Individual compounds isolated from kava can both increase or decrease dopamine concentration [86, 87].
However, in a couple of cases, blocked dopamine function has also been observed [88].
36) Lactobacillus plantarum
The probiotic Lactobacillus plantarum can increase dopamine in the brain in mice (striatum), and could potentially improve anxiety-like behaviors and psychiatric disorders [89, 90].
35) Fresh Cut Grass/Essential Oils
Hexanal is a “green” odor compound found in plants that may increase dopamine in rats (striatum) [91, 92]. Increasing dopamine is a potential mechanism in which green odors, such as fresh cut grass and plant essential oils, may improve mood and attention.
36-41) Flowering Quince, Psoralea corylifolia, Mycoleptodonoides aitchisonii, Blue trumpet vine, Prickly nightshade, Gardenia jasminoides
Flowering quince, the fruit of Chaenomeles speciosa used in Chinese traditional medicine, increases dopamine levels by inhibiting the dopamine transporter (DAT) [93].
Psoralea corylifolia fruit/seed extract and its components increase dopamine [94, 95]. This plant is used both in Ayurveda and Chinese traditional medicine.
The edible mushroom Mycoleptodonoides aitchisoniiincreases dopamine [96].
Blue trumpet vine (Thunbergia laurifolia) is a Thai herbal medicine used to treat drug addiction. It works by increasing dopamine [97, 98].
Prickly nightshade (Solanum torvum) increases dopamine and shows antidepressant activity [99].
Gardenia jasminoides can increase dopamine by inhibiting MAO-A and B [100].
Hormones that Increase Dopamine:
42) Estrogen
Estrogen may increase dopamine. Women act more impulsively in the early as opposed to the late phase of the menstrual cycle [101].
In rats, estrogen-induced improvements in recognition memory were shown to be due, in part, to increased dopamine [102].
However, dopamine’s relationship to cognitive performance is not linear – dopamine function follows an ‘inverted U-shaped’ curve, where optimal dopamine results in maximal function and both insufficient or excessive levels lead to dysfunction [103]. That is why too much estrogen is not beneficial.
43) Ghrelin
Ghrelin stimulates dopamine release in rats (amygdala, nucleus accumbens, VTA, prefrontal cortex) [104, 105].
Dopamine Drugs/Agonists
44) Nicotine
Nicotine “hi-jacks” the reward circuitry in the brain by increasing dopamine release (striatum, VTA, amygdala, nucleus accumbens, prefrontal cortex) [106, 107, 104].
45) L-dopa
L-dopa is made from tyrosine, and then converted into dopamine. Basically, it is the precursor of dopamine [108].
46) Bromantane
Bromantane increases the amount of dopamine in the brain by increasing its synthesis from tyrosine (increases Tyrosine Hydroxylase, AAAD) [109, 110].
Enhancement of dopamine is observed in the hypothalamus, striatum, ventral tegmental area, nucleus accumbens, and other regions [111, 112, 113].
By increasing dopamine, Bromantane increases alertness and wakefulness [114] and improves short-term memory, motivation, planning abilities, and attention [110].
47) Tianeptine
Tianeptine increases the release of dopamine in rats (nucleus accumbens > striatum) [115].
48) Phenibut
Phenibut is a nootropic drug that stimulates dopamine receptors [116].
49) Alcohol
Dopamine release may contribute to the rewarding effects of alcoholand may thereby play a role in promoting alcohol consumption (nucleus accumbens) [117].
50) Methylphenidate/Amphetamines
Amphetamine exerts rewarding and reinforcing effects by elevating dopamine and prolonging dopamine receptor signaling [118].
Methylphenidate works in the treatment of ADHD by increasing levels of dopamine in children’s brains.
Previous research has shown that some people with attention deficit hyperactivity disorder may have too many dopamine transporters, which results in low levels of dopamine in the brain.
The drug seems to raise levels of dopamine by blocking the activity of dopamine transporters, which remove dopamine once it has been released [119].
51) Modafinil
Modafinil seems to inhibit the reuptake of dopamine by dopamine transporter, thereby increasing the concentration in humans [120, 121].
52) Deprenyl
Deprenyl (Selegiline) increases dopamine by blocking MAO-B, an enzyme that breaks down dopamine [122].
53) MDMA
MDMA/Ecstasy increases dopamine [123].
54) Cocaine
Cocaine inhibits the dopamine transporter responsible for dopamine recycling, thereby increasing the levels [124].
Ways to Decrease Dopamine
Drugs and Supplements that Decrease Dopamine
1) Anti-psychotics
In cases of schizophrenia, you can use anti-psychotic drugs to lower dopamine signaling by blocking the receptors [125].
2) Melatonin
Melatonin suppresses dopamine activity [126].
3) Lithium
Lithium impairs dopamine release [127, 128].
4) Manganese
Long-term manganese decreases dopamine release in the brain [129, 130].
A study showed that manganese exposure, even within the safety limit, decreased dopamineproduction in primates [131].
5) Liriodenine
Liriodenine inhibits dopamine production and decreases dopamine levels [132].
6) Salvinorin A
Derived from the plant Salvia divinorum, Salvinorin A decreases dopamine [133].
7) 5-HTP
Serotonin shares the same conversion and breakdown enzymes with dopamine.
Long-term supplementation with 5-HTP, the immediate precursor of serotonin, can cause dopamine depletion, which can worsen neurological and psychiatric diseases [134].
Conditions That Decrease Dopamine
1) Inflammation
Inflammation decreases dopamine [135]. That’s why we feel less motivated and more sluggish when we are sick [135].
2) Maternal Deprivation
Maternal deprivation of rat pups leads lower dopamine levels. However, these pups reared in isolation have higher levels in response to stress [136].
3) Diet High in Saturated Fats
Saturated fats can suppress dopamine [7, 137].
4) Chronic Sugar Intake
Sugar acutely increases dopamine, which, over time, leads to a reduced number of D2 receptors and possibly a reduction in dopamine itself, leading to desensitization. These effects would not be due to the acute effects of sugar, but rather would occur over weeks to months with chronically elevated and intermittent sugar ingestion [138].
5) Iron Deficiency
Iron is a cofactor for tyrosine hydroxylase, a key enzyme in dopamine production [139]. Iron-deficient rats have reduced brain dopamine levels [139].
Low brain iron stores may contribute to ADHD symptoms because low iron levels in the brain can alter the activity of dopamine [140].
Weaning rats fed an iron-deficient diet showed decreased physical activity and increased anxiety-like behavior with a reduction of brain dopamine receptors [141].
However, some studies indicate iron deficiency has the exact opposite effect [142].
Amino acid therapy can be very effective at restoring proper neurotransmitter function and alleviating the insatiable urge to pull that some many people with trichotillomania experience. There are really two ways in which amino acids are used for people with trichotillomania. The first is to use n-acetyl cysteine, or NAC, which has been shown in clinical trials to reduce the urge to pull in about 56% of people that use NAC (see our post entitled
