Serotonin: The Brain’s Mood Booster
Serotonin: The Brain’s Mood Booster
Serotonin (5-HT) is a key neurotransmitter that regulates mood, emotion, and behavior. Low serotonin levels are linked to depression, anxiety, and irritability, while optimal levels promote happiness, emotional stability, and well-being. The brain’s serotonergic system interacts with regions such as the prefrontal cortex and limbic system, influencing mood, cognition, and the stress response. Many antidepressants, such as SSRIs, work by increasing serotonin availability, and lifestyle factors—like sunlight, exercise, and diet—can naturally enhance serotonin levels.
Foods that support serotonin production:
-
Eggs, cheese, turkey, and chicken (rich in tryptophan)
-
Salmon and fatty fish (omega-3s support serotonin receptors)
-
Nuts and seeds (almonds, walnuts, pumpkin, sunflower)
-
Tofu and soy products (plant-based tryptophan)
-
Oats and whole grains (stabilize blood sugar for serotonin synthesis)
-
Bananas (tryptophan and vitamin B6)
-
Dark chocolate (enhances serotonin release)
-
Pineapple (may positively influence serotonin levels)
