Serotonin Nature
Identify whether serotonin is your dominant neurotransmitter.

Keeping your balance
Exploration
Complete your profile by taking the 3 other dominance tests (dopamine, acetylcholine, GABA). Your dominant neurotransmitter determines your natural strengths, cognitive style, and most effective health strategies for you. A complete profile also helps identify your weak point, meaning the neurotransmitter most likely to become depleted under stress.
General balance
Even if serotonin is not your dominant, maintain sufficient tryptophan intake (eggs, turkey, banana, dark chocolate), expose yourself to natural light each morning, and practice regular physical activity. These habits support your baseline serotonin production and protect your sleep, mood, and pain threshold.
Targeted nutrition
Focus your nutritional efforts on your dominant neurotransmitter identified by the other tests: tyrosine for dopamine (meat, fish, almonds), choline for acetylcholine (eggs, liver, soy lecithin), or glutamine for GABA (almonds, lentils, broccoli). Each profile has its priority foods and optimal meal timing.
Keeping your balance
Nutrition
Nourish your serotonin with structured meals around tryptophan: eggs in the morning, fish or turkey at midday, banana-dark chocolate-cashew snack in the afternoon. The combination of tryptophan plus complex carbohydrates (brown rice, sweet potato) at dinner promotes serotonin synthesis in the evening, improving sleep quality and nighttime recovery.
Developing consistency
The Achilles' heel of the serotonergic profile is inconsistency: you start with enthusiasm but struggle to maintain effort over time. Use short-term goals (21 days), a visual calendar to track your habits, and associate with a GABA or acetylcholine profile that will bring you the structure and regularity you lack.
Physical activity
Vary your physical activities to avoid the typical boredom of the serotonin profile: alternate team sports (your natural sociability carries you), rhythmic activities (dance, swimming, martial arts), and outdoor sports. 30 minutes of aerobic exercise daily stimulates tryptophan hydroxylase and maintains your natural optimism. What matters is regularity rather than intensity.
Light and rhythm
Your serotonin is directly linked to light: expose yourself to sunlight each morning for 20 to 30 minutes. In autumn-winter, serotonergic profiles are particularly vulnerable to decreased light (seasonal depression). Maintain regular sleep and wake times to stabilize the serotonin-melatonin cycle and compensate for your natural tendency to live by whim.
Relationships and emotions
Your natural sociability is a strength, but watch for the tendency to accumulate superficial relationships at the expense of deep connections. Cultivate a few lasting, trusting relationships. Your pragmatism can sometimes be perceived as insensitivity: take time to listen to others' emotions without immediately trying to solve the problem. Relational depth also nourishes serotonin through oxytocin.
Keeping your balance
Nutrition
Your serotonin is naturally elevated: maintain it without excess. Continue tryptophan intake (eggs, turkey, banana, dark chocolate, pumpkin seeds) but also integrate foods rich in tyrosine (almonds, avocado, red meat, aged cheese) to stimulate dopamine, which will bring you the motivation and perseverance you sometimes lack. Balance proteins and carbohydrates at each meal to avoid mood fluctuations.
Stimulating dopamine
Your main challenge is lack of consistency and long-term motivation, which relate to dopamine. Set yourself measurable objectives with short deadlines (7 to 21 days). Keep a journal of your accomplishments. Learn a new skill regularly to stimulate dopamine through novelty. L-tyrosine (in the morning on an empty stomach) or mucuna pruriens can support your dopamine without decreasing your serotonin. Doses are set with your doctor or your naturopath, all the more so if you already take a medication.
Structured physical activity
Your natural tendency is to exercise by inclination then stop when the desire passes. Counter this with structured commitment: register for a group class with fixed times, find a reliable training partner, or engage in a progressive sports challenge (running with a training plan, for example). Regular exercise maintains serotonin-dopamine balance and prevents weight gain, to which serotonergic profiles are vulnerable.
Relational depth
You are naturally the life of the party, the group gatherer. But your social ease can mask lack of depth in relationships. Consciously invest in 3 to 5 deep and lasting relationships. Resist the temptation to turn the page too quickly when a relationship faces difficulty. The ability to navigate conflicts and deepen bonds is a muscle the serotonin profile must actively train.
Planning and structure
Your serotonergic nature pushes you to live day to day, which is a strength for immediate well-being but a weakness for building long-term projects. Use a paper or digital agenda, plan your weeks Sunday evening, and honor your commitments even when a more tempting opportunity presents itself. Financially, set up automatic savings transfers to compensate for your natural tendency to spend in the moment.
Prevention of excess
Serotonin excess, though rare naturally, can occur if you combine a strong serotonergic dominance with 5-HTP supplements, Saint John’s Wort, or SSRI antidepressants. Saint John’s Wort has many drug interactions (the contraceptive pill, anticoagulants, antiretrovirals, antidepressants): talk to your doctor before taking it. Avoid supplementing with 5-HTP or tryptophan without professional advice: your serotonin is already elevated. Watch for signs of serotonin excess: excessive drowsiness, apathy, weight gain, decreased libido, emotional blunting. If in doubt, platelet serotonin or urinary 5-HIAA testing can objectify your status.

How to read this test
Identify whether serotonin is your dominant neurotransmitter. Serotonin governs pragmatism, sociability, sensory pleasure, and the ability to live in the present moment. The higher your score, the more serotonin dominates your nervous profile.
It assesses whether serotonin is your dominant neurotransmitter, meaning the one that shapes your personality, memory, and cognitive functioning the most.
Serotonin is the neurotransmitter of joie de vivre, optimism, sleep, and satiety. Personalities with serotonergic dominance are joyful, sociable, enthusiastic, pragmatic, and fully live in the present moment.
Strengths
- Understand whether your joie de vivre, pragmatism, and sociability reflect a serotonergic dominance
- Identify your natural strengths: communicative optimism, ability to live in the present moment, manual skill, and artistic sense
- Adapt your lifestyle to nourish your serotonin (tryptophan, natural light, regular exercise) and cultivate consistency
Limitations
- Subjective self-assessment, not clinically validated
- Neurotransmitter profile fluctuates according to lifestyle
- Does not replace urinary neurotransmitter testing
