🧠 Mental Health: Serotonin, Dopamine and GABA — the Chemistry of Mood
Mood isn't just "in your head" — it's also biochemistry
We're used to thinking mood is "just in your head." But behind it is chemistry: serotonin, dopamine and GABA control joy, motivation and calm. Let's look at how to support their balance.
Neurotransmitters
Neurotransmitters are the chemical "messengers" of the brain. They pass signals between cells and define mood, energy and stress resilience.
- Brain messengers.
- Mood.
- Energy.
- Stress resilience.
Serotonin
Serotonin is the "good mood hormone." Its sufficiency gives calm and clarity; its lack is linked to anxiety and low mood.
- Good mood.
- Calm.
- Clarity.
- Lack — anxiety.
Dopamine
Dopamine is the "motivation hormone." It gives drive, focus and a sense of reward. Its lack — apathy and loss of interest.
- Motivation.
- Drive.
- Focus.
- Lack — apathy.
GABA
GABA is the nervous system's "brake." It lowers excitation and helps calm down. Its lack — anxiety and restlessness.
- Lowers excitation.
- Calm.
- Against anxiety.
- Relaxation.
Nutrition
Neurotransmitters are built from amino acids and vitamins. Protein provides the "raw material," B-vitamins and magnesium help synthesis.
- Protein — raw material.
- Tryptophan for serotonin.
- Tyrosine for dopamine.
- Magnesium for calm.
Food sources
| Substance | Food | Comment |
|---|---|---|
| Tryptophan | Turkey | Serotonin |
| Tyrosine | Eggs | Dopamine |
| Magnesium | Nuts | GABA/calm |
| B-vitamins | Whole grains | Synthesis |
Practice
- Protein in every meal.
- Enough sleep.
- Daylight.
- Movement and walks.
- Reduce stress.
- Consult a doctor.
