Braverman Test: Dopamine Deficiency
Assess a potential dopamine deficit through this questionnaire inspired by the work of Dr Eric Braverman. Dopamine is the neurotransmitter of energy, motivation and concentration. A deficit results in fatigue, lack of motivation and concentration difficulties.
This test evaluates your current dopamine level according to Dr Eric Braverman. Unlike the dominance test which identifies your deep nature, this one detects a current functional deficit.
Dopamine deficiency manifests as chronic fatigue, procrastination, lack of motivation, concentration difficulties, a tendency toward addictions (sugar, screens, coffee) and loss of pleasure in daily activities.
Points forts
- + Detect a current dopamine deficit, even if it is not your dominant neurotransmitter
- + Identify early signs of deficiency: unexplained fatigue, procrastination, loss of motivation, difficulty getting out of bed in the morning
- + Guide a targeted support protocol (tyrosine, rhodiola, B vitamins, physical exercise) before the deficit worsens
Limites
- - Subjective self-assessment, not clinically validated
- - The neurotransmitter profile fluctuates based on lifestyle
- - Does not replace a urinary neurotransmitter panel

Understanding your result
Dopamine is synthesized from tyrosine, an amino acid found in dietary proteins. The enzyme tyrosine hydroxylase converts tyrosine to L-DOPA, then AADC transforms it into dopamine. This process requires iron, vitamin B6 and folates as cofactors. A low score means that this production chain is functioning correctly and that the four major dopaminergic pathways (mesocortical, mesolimbic, nigrostriatal and tuberinfundibular) are fulfilling their role.
Remain vigilant about early signals
Even in the absence of current deficiency, monitor the first signs of emerging deficit: increased need for coffee or sugar to get started, growing difficulty waking up in the morning, progressive decline in motivation or pleasure in usual activities. Chronic stress, lack of sleep and overstimulation by screens and social media progressively deplete your dopaminergic reserves. Regular monitoring of your ferritin (key cofactor) is recommended, especially in menstruating women.
Maintaining your dopamine daily
Morning physical exercise is the most powerful natural dopamine stimulant: 30 minutes of sustained activity is enough to significantly increase its release. Expose yourself to natural light upon waking to synchronize your circadian rhythm and optimize dopamine production. Integrate tyrosine-rich foods into your breakfast (eggs, almonds, cheese, meat, fish). Limit sources of easy dopamine (social networks, refined sugar, video games) that desensitize your D2 receptors in the long term. Finally, cultivate novelty and set yourself small achievable daily goals to stimulate your reward circuit in a healthy way.

Understanding the pathophysiology
Dopamine is a catecholamine synthesized in two steps: tyrosine is first converted to L-DOPA by tyrosine hydroxylase (rate-limiting enzyme, dependent on iron, B6 and folates), then to dopamine by AADC (dependent on B6). When these cofactors are lacking, dopamine production drops. The failing mesocortical pathway explains your brain fog and concentration difficulties. The underactive mesolimbic pathway causes anhedonia and compulsive sugar cravings, because your brain desperately seeks to stimulate a weakened reward circuit.
Markers to monitor
According to the Braverman approach, clinical signs to monitor are: persistent lack of motivation, concentration difficulties, cravings for sugar, caffeine or stimulants, slowness of movement, brain fog, need for long sleep and emotional blunting. On the biological side, testing may include: urinary catecholamines (homovanillic acid or HVA will be lowered in case of deficit), platelet MAO activity, plasma prolactin (which rises when dopamine drops, because the tuberinfundibular pathway regulates prolactin) and especially ferritin, essential cofactor of tyrosine hydroxylase. A ferritin below 50 ng/mL already compromises dopamine synthesis.
Pro-dopamine nutrition
Prioritize a protein-rich breakfast, the true foundation of your dopamine production. Tyrosine, the direct precursor, is found in almonds, avocado, banana, dairy products, meat, fish, eggs and soy. Phenylalanine, a precursor of tyrosine, is present in the same protein sources. Incorporate iron-rich foods (red meat, liver, blood sausage) to support tyrosine hydroxylase. Absolutely avoid refined sugar which causes a temporary spike in dopamine followed by a drop lower than the initial level, creating a vicious cycle of dependence. Also reduce excessive caffeine which depletes your reserves in the long term.
Targeted supplementation
L-tyrosine (500 to 2000 mg in the morning on an empty stomach) directly provides the dopamine precursor. Mucuna pruriens (200 to 400 mg of extract standardized to L-DOPA) provides natural L-DOPA, bypassing the rate-limiting step of tyrosine hydroxylase. Vitamin B6 in active form P5P (25 to 50 mg) is a cofactor for both enzymes in the synthesis chain. Bisglycinate iron (if ferritin below 50 ng/mL) restores the main cofactor of tyrosine hydroxylase. Folates in the form of 5-MTHF (400 mcg) support the methylation necessary for dopamine recycling. Magnesium (300 mg, bisglycinate or citrate) and vitamin D (2000 IU) complete the protocol by supporting overall neuronal function.
Daily anti-deficiency habits
Morning physical exercise is the most powerful natural dopamine stimulant: even 20 minutes of brisk walking or sport significantly increase dopamine release in the striatum. Cold showers (1 to 3 minutes of cold water at the end of your shower) cause a 250% increase in dopamine for approximately 3 hours, according to studies. Expose yourself to natural light upon waking to synchronize your circadian rhythm. Set yourself small achievable objectives each day to reactivate your reward circuit. Practice meditation and listen to music you enjoy, two activities that stimulate dopamine release. Drastically limit screens and social media which desensitize your D2 receptors through permanent overstimulation.
Herbal medicine and gemmo-therapy
Mucuna pruriens is the reference plant: it naturally contains L-DOPA and directly increases dopamine levels. Rhodiola rosea acts as a MAO-B inhibitor, the enzyme that breaks down dopamine, prolonging its action in the synapse. Ginseng (Panax ginseng) supports catecholamine production and improves stress resistance. Green tea provides a duo of L-theanine and caffeine that stimulates dopamine without the crash effect of coffee alone. In gemmo-therapy, oak bud (Quercus robur) is a global endocrine tonic that supports the adrenals and vitality, while sequoia bud (Sequoiadendron giganteum) is a neuroendocrine stimulant that restarts deep energy.

Understanding deep pathophysiology
At this level of deficiency, the dopamine synthesis chain is significantly compromised. Tyrosine hydroxylase, the rate-limiting enzyme that converts tyrosine to L-DOPA, chronically lacks its cofactors: iron (often severely depleted ferritin), vitamin B6 in active form P5P, and folates. The second enzyme, AADC, which converts L-DOPA to dopamine, is also dependent on B6. Result: all four dopaminergic pathways are suffering simultaneously. The failing mesocortical pathway causes brain fog and severe amotivation. The extinguished mesolimbic pathway explains anhedonia and compensatory addictive behaviors. The weakened nigrostriatal pathway causes motor slowness evoking a functional pre-Parkinsonian picture. This profound deficit requires a structured protocol and follow-up.
Clinical and biological markers
According to the approach of Dr Braverman and Dr Hertoghe, major clinical markers of severe deficiency are: complete absence of motivation, inability to concentrate for more than a few minutes, irresistible cravings for sugar, caffeine or stimulants, marked slowness of movement and thought, permanent brain fog, excessive need for sleep (more than 10 hours) and complete emotional blunting. On the biological side, check: 24-hour urinary catecholamines (homovanillic acid or HVA will be significantly lowered), plasma prolactin (which rises sharply when dopamine drops, because it is dopamine that normally inhibits prolactin secretion via the tuberinfundibular pathway), serum ferritin (key cofactor, aim for at least 50 ng/mL, ideally 80), and a B vitamin panel (B6, B9, B12). These biological markers will confirm or nuance the clinical picture.
Priority dietary reform
With such a marked deficit, a protein-rich breakfast becomes non-negotiable: aim for 30 g of protein in the morning (3 eggs, or 100 g of meat or fish, or 200 g of cottage cheese with almonds). The tyrosine contained in these proteins is the direct precursor of your dopamine. Daily integrate: almonds, avocado, banana, dairy products, meat, fish, eggs and legumes. Foods rich in heme iron (calf liver, blood sausage, red meat) are essential to restore ferritin, a cofactor of tyrosine hydroxylase. Completely eliminate refined sugar: it causes an artificially elevated dopamine spike followed by a crash that worsens the deficiency. Reduce caffeine significantly which masks the deficit without correcting it. Pair plant-based iron sources with vitamin C to optimize their absorption.
Structured supplementation protocol
A marked deficit justifies a comprehensive protocol. L-tyrosine (1000 to 2000 mg in the morning on an empty stomach, 30 minutes before breakfast) provides the direct precursor. Mucuna pruriens (300 to 400 mg of extract standardized to 15-20% L-DOPA) provides natural L-DOPA, bypassing the rate-limiting step of tyrosine hydroxylase. Vitamin B6 in active form P5P (50 mg per day) is an indispensable cofactor for both enzymes in the synthesis chain. Bisglycinate iron (20 to 30 mg per day if ferritin below 50 ng/mL) restores the main cofactor. Folates in the form of 5-MTHF (400 to 800 mcg) support methylation. Bisglycinate magnesium (300 to 400 mg in the evening) supports neuronal function and sleep. Vitamin D (2000 to 4000 IU per day) completes the protocol. Recommended duration: 3 months minimum, with reassessment.
Essential lifestyle reforms
Morning physical exercise is your absolute priority: it is the most powerful natural dopamine stimulant. Start with 20 minutes of brisk walking if energy is lacking, then progressively increase toward 30 to 45 minutes of sustained activity. Cold showers are a powerful therapeutic tool: immersion in cold water causes a 250% increase in dopamine for approximately 3 hours, an effect comparable to certain medications. Start with 30 seconds of cold water at the end of your shower. Expose yourself to intense natural light within the first 30 minutes after waking. Eliminate or drastically reduce screens, social media and video games that desensitize your D2 receptors through chronic overstimulation. Set yourself a single small achievable objective each day to restart your reward circuit. Mindfulness meditation (even 10 minutes a day) and listening to music you enjoy stimulate dopamine release in a healthy way.
Herbal medicine and gemmo-therapy support
Mucuna pruriens is the major plant: it naturally contains L-DOPA and directly elevates dopamine levels (200 to 400 mg of standardized extract). Rhodiola rosea (200 to 400 mg of extract standardized to rosavins) acts as a natural inhibitor of MAO-B, the enzyme that breaks down dopamine in the synapse, prolonging its action. Ginseng (Panax ginseng, 200 to 400 mg) supports overall catecholamine production and improves stress resistance, a major factor in dopaminergic depletion. Green tea, thanks to its L-theanine and caffeine duo, offers mild and prolonged dopaminergic stimulation without the crash effect of coffee. In gemmo-therapy, oak bud (Quercus robur, 5 to 15 drops in the morning) is a powerful endocrine tonic that supports the adrenals and restarts vitality. Sequoia bud (Sequoiadendron giganteum, 5 to 15 drops in the morning) is a deep neuroendocrine stimulant, particularly indicated in profound exhaustion with loss of motivation.
