Last updated August 2, 2021.Edited and medically reviewed by Patrick Alban, DC. Written by Deane Alban.

Low dopamine levels can lead to a lack of motivation, fatigue, addictive behavior, mood swings, and memory loss. Learn how to increase dopamine naturally.

Dopamine is a major neurotransmitter thats a key factor in motivation, productivity, and focus.

Dopamine helps give you your zest for life.

However, lifestyle habits, diet, and illness can deplete dopamine levels, leaving you lethargic and apathetic.

If this sounds like you, a low dopamine level may be the reason.

Consider these healthy, proven ways to increase dopamine naturally.

Harness Your Brains Reward System

Dopamine functions as a survival mechanism by releasing energy when a great opportunity presents itself to you.

Dopamine rewards us when our needs are met.

We love dopamine surges because of the way they make us feel.

But the constant hunt for your next dopamine boost can turn you into a wolf on Wall Street, driven by addictions, greed, and lust.

Here are two healthy ways to regulate your dopamine level that work with your brains built-in reward system to improve, rather than ruin, your life.

Enjoy the Quest

Our distant ancestors were engaged in a constant quest just to survive.

They got a dopamine surge every time they spotted a new patch of berries or a better fishing spot because this meant survival.

While you can still pick berries and fish, there are endless other healthy ways you can enjoy the quest of living a modern life.

You can forage for new music to download, specialty ingredients to cook with, a bargain travel package, a hard-to-find collectors item, or that perfect gift for a loved one.

You can engage in quest-oriented hobbies like geocaching, genealogy, bird watching, and collecting of all kinds.

These kinds of hobbies are ideal for keeping up dopamine levels since there is always something new to be discovered.

Each new discovery provides a dopamine boost.

Conditions Associated With Dopamine

If someone has abnormalities in the neurotransmitter dopamine, they may experience one or more of the following symptoms:

  • Aches and pains
  • Delusions
  • Hallucinations

A common condition which is believed to be associated with dopamine is schizophrenia. In schizophrenia, the positive symptoms of hallucinations and delusions are thought to be linked to high dopamine levels.

It has been found that dopamine abnormalities in the mesolimbic and prefrontal areas of the brain exist in those with schizophrenia. The dopamine systems in these areas become overactive and can therefore lead to the experience of hallucinations and delusions.

Another condition which has shown links to dopamine levels is Parkinsonâs disease. As dopamine can play a role in sending messages to parts of the brain that control movement and coordination, low dopamine levels can cause disruptions in movement and may ultimately be a cause for movement disorders such as Parkinsonâs disease.

Substance use disorder is also a condition which can affect dopamine levels as it can alter the threshold for dopamine activation and signaling. As someone continues to use a drug which causes a âhighâ of dopamine levels, the threshold for achieving this high increases.

This means it will become increasingly difficult for someone to experience the positive effects of dopamine without resulting to over-using the drug.

How Does Dopamine Affect Neurotransmitters

Dopamine has a number of different effects in the brain. Its important to remember that this neurotransmitter changes the way nerve cells function, by either stimulating or inhibiting them. The precise effect of the dopamine depends on which receptors the dopamine attaches to and what chain reactions it initiates.

How Does Dopamine Make You Feel

Dopamine: The neuro

Dopamine causes you to want, desire, seek out, and search. It increases your general level of arousal and your goal-directed behavior. Dopamine makes you curious about ideas and fuels your search for information. Dopamine creates reward-seeking loops in the sense that people will repeat pleasurable behavior, from checking Instagram to taking drugs.

Dopamine Supplements And Supplementation

Dopamine is found in many types of food, but dopamine itself cant cross into the brain from the bloodstream, so eating foods that contain dopamine wont raise dopamine levels in the brain. But dopamines precursor molecule, tyrosine, can cross the blood-brain barrier, according to a review published in November 2015 in the Journal of Psychiatric Research.

Tyrosine is an amino acid found naturally in protein-rich foods, such as cheese, nuts, and meat. Under certain circumstances, tyrosine supplements can help boost dopamine levels in the brain, leading some to believe that tyrosine supplementation could help with neurological and mental health conditions involving low dopamine. In fact, the Parkinsons disease drug Levodopa was originally synthesized from one form of tyrosine.

But scientific studies have failed to show that this is the case. Tyrosine supplements dont appear to have much if any effect on physiology, thought, or behavior.

What Is The Reward System And What Does It Do

In the 1950s, James Olds and Peter Milner implanted electrodes in the brains of rats and allowed the animals to press a lever to receive a mild burst of electrical stimulation to their brains. Olds and Milner discovered that there were certain areas of the brain that rats would repeatedly press the lever to receive stimulation to. They found a region known as the , which lies just below the front end of the corpus callosum, to be the most sensitive. One of the rats in their experiment pressed a lever 7500 times in 12 hours to receive electrical stimulation here.

Olds and Milner’s experiments were significant because they appeared to verify the existence of brain structures that are devoted to mediating rewarding experiences. For, if the rats were lever-pressing repeatedly to receive stimulation to these areas, it suggested they were enjoying the experience. Subsequent studies attempted to more thoroughly map out these “reward areas,” and it was discovered that some of the most sensitive areas are situated along the medial forebrain bundle. The medial forebrain bundle is a large collection of nerve fibers that travels between the VTA and the lateral hypothalamus, making many other connections along the way. Some areas of the medial forebrain bundle were found to be so sensitive that rats would choose receiving stimulation to them over food or sex.

Psychiatric And Neurodegenerative Disorders

Swedish pharmacologist and neuroscientist Arvid Carlsson won the Nobel prize in 2000 for his research on dopamine, showing its importance in brain function. He helped show that the neurotransmitter is heavily involved in the motor system. When the brain fails to produce enough dopamine, it can result in Parkinsons disease. The primary treatment for Parkinsons disease is a drug called L-dopa, which spurs the production of dopamine.

Dopamine has also been implicated in schizophrenia and ADHD the brain systems underlying these conditions are complex. The activity of the dopamine system depends on the state of ones dopamine receptors, and in people with these conditions, the chemical interacts with other factors in ways that have yet to be explained.

What If I Have Too Little Or Too Much Dopamine

What is dopamine?

Dopamine dysregulation could mean that the brain is producing too little or too much dopamine. Low dopamine, or dopamine deficiency, can be caused by a variety of factors, including conditions such as Parkinsons disease, schizophrenia, and depression. Drug and sugar addiction have also been found to cause dopamine deficiency over time. Some low dopamine symptoms include fatigue, moodiness, dysphoria, physical pain, and changes in weight, sex drive, and ability to focus. As many other conditions share these symptoms, its important to consult your health care provider if youre experiencing these symptoms.

Its also possible to have too much dopamine. Effects of overly high dopamine levels include high libido, anxiety, difficulty sleeping, increased energy, mania, stress, and improved ability to focus and learn, among others. When certain parts of the brain are exposed to too much dopamine, for instance right after an individual takes illicit drugs, other behaviors may be present. These can include aggression, hallucinations, twitching, nausea and/or vomiting, and depression.

      Do Serotonin And Dopamine Work Together

      Although serotonin and dopamine work differently and differ in function, neurotransmitters interact with each other in some way.

      Serotonin and dopamine interact with each other to maintain a chemical balance in the body.Serotonin and dopamine have opposite effects on appetite. Whilst serotonin suppresses it, low levels of dopamine can stimulate hunger.

      In anatomical studies, it has been found that dopaminergic neuronal bodies and terminals are modulated by serotonin, and they receive rich projections from serotonin neurons. These strong neuronal connections seem to promote the functional modulation of serotonin over dopaminergic activities in the neural network.

      For instance, a serotonin receptor named 5HT2 seem to inhibit dopaminergic activity, whereas the 5HT2 receptor antagonists counteracts the inhibition of dopaminergic activity.

      Interactions between serotonin and dopamine could provide the framework for understanding the mechanisms behind some of the impulsive aggressive behaviors displays in people. Since serotonin is thought to have functional regulation over dopaminergic systems, deficiencies in serotonin functions may result in hyperactivity of the dopamine system, promoting impulsive behavior.

      This relationship may account for some of the serotonin and dopamine dysfunctions in those with impulsive aggression. This is supported by studies on rats.

      Study: Neurotransmitter Dopamine Plays Role in Human ...

      Dopamine does not cross the bloodbrain barrier, so its synthesis and functions in peripheral areas are to a large degree independent of its synthesis and functions in the brain. A substantial amount of dopamine circulates in the bloodstream, but its functions there are not entirely clear. Dopamine is found in blood plasma at levels comparable to those of epinephrine, but in humans, over 95% of the dopamine in the plasma is in the form of dopamine sulfate, a conjugate produced by the enzyme sulfotransferase 1A3/1A4 acting on free dopamine. The bulk of this dopamine sulfate is produced in the mesentery that surrounds parts of the digestive system. The production of dopamine sulfate is thought to be a mechanism for detoxifying dopamine that is ingested as food or produced by the digestive processlevels in the plasma typically rise more than fifty-fold after a meal. Dopamine sulfate has no known biological functions and is excreted in urine.

      Beyond its role in modulating blood flow, there are several peripheral systems in which dopamine circulates within a limited area and performs an exocrine or paracrine function. The peripheral systems in which dopamine plays an important role include the immune system, the kidneys and the pancreas.

      Dopamine And Mental Health

      Dopamine also has significant function in some mental health conditions. A few of these include:

      • Schizophrenia: Dopamine dysregulation has been found to be present in the brains of individuals with schizophrenia. It may be at least partly responsible for both positive and negative symptoms of schizophrenia, including hallucinations and delusions as well as a lack of pleasure and motivation.
      • Depression: While depression is classically associated more often with serotonin dysregulation, some research supports the idea that dopamine could also be associated with the loss of pleasure, or anhedonia, associated with depression.
      • ADHD: Dopamine is thought to be a key factor in the development of ADHD. Studies have shown that lower than usual amounts of dopamine in the brain are often present alongside symptoms of ADHD.
      • Anxiety: One study linked anxiety to insufficient dopamine in the amygdala. Since the amygdala is implicated in the fight or flight response, dopamine could act as a way to quiet the amygdala when it reacts to a false alarm. Without enough dopamine to stop the fight or flight response, higher levels of anxiety could be the result.

      Research exploring the many links between dopamine and mental health is ongoing, and experts are still discovering all the ways dopamine is connected to behavioral health.

      How Can I Adjust My Dopamine Levels

      You can boost a low level of dopamine by addressing the cause of the problem. This could be a mental illness, stress, not getting enough sleep, drug abuse, being obese, or eating too much sugar and saturated fat. Low dopamine can also be caused by a problem with the adrenal glands.

      You can increase your dopamine levels naturally by eating a healthy diet, including foods rich in L-Tyrosine . These include almonds, avocados, bananas, beef, chicken and eggs. Turmeric, vitamin D, magnesium and omega-3 supplements are also claimed to increase dopamine levels.

      Activities that make you feel good will also raise dopamine. These include exercising, meditating, having a massage and getting enough sleep. Thinking about your achievements and all the good things in your life can also help.

      If low dopamine is causing depression or schizophrenia, your doctor may give you medicines such as antidepressants or mood stabilisers, as well as other treatments for mental illness.

      People with Parkinsons disease are usually given medicines to boost their dopamine levels. These can often cause a big improvement in symptoms.

      Volume Transmission Receptor Signalling And Transporter Functions

      Neuromodulators such as DA, NA, and acetylcholine can diffuse far from the release site and activate receptors in a considerable distance from the terminal . This process, which is known as volume transmission, can activate receptors as far as 8 m from the release site, in case of striatal dopamine . A long-range diffusion is also possible due to the circulation of the cerebrospinal fluid along the peri-vascular space . Peri-vascular CSF currents may supply neuromodulators far from their site of release, to activate receptors in area lacking direct projections.

      Brain Circuit Shows How Dopamine Controls Animal Behavior

      When you take an action that helps ensure your survival such as eating, drinking, having sex, or making money dopamine is released.

      This ensures that youll continue to do whats needed to survive .

      Neuroscientist John Coates, PhD, is a renowned authority on risk taking.

      He reveals in his national bestseller, The Hour Between Dog and Wolf, that these natural activities can raise dopamine by 50-100% over baseline levels, but drugs increase dopamine much, much more.

      Nicotine increases dopamine by 200%, cocaine 400%, and amphetamines a jaw-dropping 1,000%.

      Few people realize that they are self-medicating to get a dopamine boost when they engage in potentially addictive and self-destructive behaviors.

      The use and abuse of caffeine, alcohol, sugar, nicotine, drugs, shopping, sex, video games, online porn, power, and gambling are all effective dopamine boosters that can wreak havoc on your life.

      Best Ways To Increase Dopamine Levels Naturally

      Dopamine is an important chemical messenger in the brain that has many functions.

      Its involved in reward, motivation, memory, attention and even regulating body movements .

      When dopamine is released in large amounts, it creates feelings of pleasure and reward, which motivates you to repeat a specific behavior .

      In contrast, low levels of dopamine are linked to reduced motivation and decreased enthusiasm for things that would excite most people .

      Dopamine levels are typically well regulated within the nervous system, but there are some things you can do to naturally increase levels.

      Here are the top 10 ways to increase dopamine levels naturally.

      Risks And Side Effects

      We absolutely need this neurotransmitter to function properly, and there are many ways to boost levels naturally. But levels are also increased with some not-so-healthy actions or substances, like drinking alcohol, eating sugary foods, using drugs like nicotine and cocaine, and engaging in other rewarding behaviors.

      These acts of self-medicating can cause health issues down the line and sometimes be self-destructive or addictive behaviors.

      When it comes to using pharmaceutical medications that boost dopamine or mimic it in the brain, there are some possible side effects, including nausea, dizziness, hallucinations, impulse control disorders and low blood pressure.

      While increasing these hormones is important for some health conditions, reducing the production of this neurotransmitter is sometimes necessary.

      Dopamine antagonists are a class of drugs that reduce dopamine activity in the brain. These drugs are used on people who produce too much of the hormone and deal with health issues like schizophrenia and bipolar disorder.

      What Happens If I Have Too Much Or Too Little Dopamine

      Having low levels of dopamine can make you less motivated and excited about things. Its linked to some mental illnesses including depression, schizophrenia and psychosis.

      Having too much dopamine or too much dopamine concentrated in some parts of the brain and not enough in other parts is linked to being more competitive, aggressive and having poor impulse control. It can lead to conditions that include ADHD, binge eating, addiction and gambling.

      In Parkinsons disease, the nerve cells that produce dopamine gradually die. Because dopamine helps control the muscles, this leads to problems with muscle stiffness and movements.

      The symptoms of a dopamine imbalance depend on what is causing the problem. They include:

      • muscle cramps, spasms or stiffness
      • digestion problems, such as constipation or reflux
      • moving or speaking more slowly than usual
      • feeling tired and unmotivated, or sad and lacking hope
      • having low libido
      • hallucinations
