Ever wonder why some days you feel upbeat and focused while others seem heavy and sluggish? One key player behind those shifts is serotonin, a brain chemical that helps regulate mood, sleep, appetite, and even digestion. Some research suggests that when serotonin levels are imbalanced, individuals may experience changes in energy, focus, and emotional balance, which have been linked to changes in both mental and physical health.
You can take simple, natural steps to support your body’s serotonin production. By making small, consistent changes in daily habits, you may support a more positive mood, better sleep, and improved overall well-being. This guide will show you 12 practical, science-backed ways to increase serotonin levels and feel your best.
Serotonin is a neurotransmitter, or brain chemical, that affects how you feel, sleep, and function. It sends signals between nerve cells in the central nervous system, helping maintain emotional balance, focus, and overall physical health. This brain chemical regulates mood, appetite, digestion, and blood clotting, while also supporting healthy muscles, bones, and skin.
Research suggests that changes in serotonin function and how serotonin receptors respond may play a role in mood disorders, including depression and seasonal affective disorder, particularly in people with a history of these conditions.3 While serotonin is not the sole cause, disruptions in its activity can influence emotional processing and contribute to low mood.
Pairing serotonin-friendly habits with other natural mood support strategies can help maintain emotional balance more consistently.
Low serotonin levels are associated with various changes in mood, energy, and daily functioning. Recognizing these signs can help you explore options to support overall well-being with a healthcare provider.
Persistent low mood or depressive symptoms that affect daily life.
Fatigue or low energy despite getting enough rest.
Feelings of anxiety, irritability, or heightened stress response.
Trouble falling asleep, staying asleep, or waking up refreshed.
Strong sugar cravings or changes in appetite that may affect physical health.
Improving mood and overall well-being may be supported by various lifestyle changes. These changes, such as eating foods that supply the essential amino acid tryptophan, supporting gut health, getting more sunlight, and staying active, are thought to influence serotonin production. They may also support serotonin neurons and receptors, so they function more effectively.
Tryptophan is an essential amino acid your body uses to make serotonin.5 The brain uses tryptophan to synthesize serotonin. Eating tryptophan-rich foods like turkey, salmon, eggs, nuts, tofu, oats, and dairy may support this process. Combining these with other amino acids from high-protein foods is thought to support brain function and serotonin production.
Omega-3 fatty acids from salmon, mackerel, flaxseeds, and chia seeds help nerve cells communicate effectively. Research suggests they may influence serotonin release.8 Some studies have found that including these healthy fats regularly may be associated with improved mood in people experiencing feelings of anxiety or low mood. However, more research is needed to confirm the effect.
A large majority of the body’s serotonin is found in the gastrointestinal tract, where it helps regulate digestion and gut function.2 The brain produces its own supply of serotonin, a process distinct from serotonin production in the gut.
A healthy gut environment, supported by probiotic-rich foods like yogurt, kefir, kimchi, and kombucha, is thought to help serotonin neurons in the gut function properly. Fermentable fiber from foods like leafy greens, beans, and oats feeds beneficial gut bacteria, which produce metabolites that can influence serotonin activity through the microbiota–gut–brain axis.7
Physical activity is known to stimulate the release of neurotransmitters, and research suggests it may influence serotonin production and how serotonin receptors respond.1 Studies have found that aerobic exercise, strength training, or yoga may be linked to increased serotonin levels and a more positive mood. Regular movement also supports relaxation, enhancing overall mental and physical wellness.
Bright light exposure is known to increase vitamin D levels, and some research suggests this may help with serotonin synthesis.9 Bright light therapy has been used to address symptoms of seasonal affective disorder and other affective disorders. Spending 15–30 minutes in natural sunlight in the morning is associated with a more positive mood for some people.
Chronic stress is associated with changes in serotonin levels. Mindfulness practices like meditation, deep breathing, and journaling are known to help calm the nervous system and reduce the stress response, which may support a more positive mood and overall brain function.
Research on massage therapy suggests it may influence serotonin and dopamine levels while lowering stress hormones.4 It is known to relax muscles and improve circulation. Massage therapy is often used to promote relaxation, which may help create a sense of calm for some individuals.
Simple actions like keeping a gratitude list, listening to uplifting music, or visualizing happy memories are thought to encourage a more positive mood and may influence brain chemicals that regulate emotional well-being.
Certain supplements like ashwagandha and ginseng have been studied for their potential to improve mood and reduce stress. While early research suggests possible benefits for serotonin production, more studies are needed. Always talk with a healthcare professional before adding herbal products, especially if you take selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors.
Strong social connections may be associated with improved well-being. Spending time with friends, volunteering, or joining group activities is known to support mental health and may encourage the release of neurotransmitters in the brain. Shared positive emotions can reinforce feelings of belonging and happiness.
Laughter is known to increase positive mood and may influence brain chemicals like serotonin and dopamine. Watching a comedy, sharing jokes, or simply finding moments to smile during the day is often associated with improved mood and mental well-being
Tryptophan supplements, 5-HTP, SAMe, and St. John’s Wort are sometimes used to boost serotonin levels. While some people find them helpful, it is important to be aware that excessive serotonin can lead to serotonin syndrome, a potentially serious condition. If you take medications for mental disorders, consult a healthcare professional before trying any supplements.
Combining multiple natural ways to boost serotonin can create a stronger, more lasting effect on mood, sleep, and overall well-being. Pairing nutrition, physical activity, and light exposure helps support serotonin production, serotonin receptors, and overall brain function for better mental and physical health.
Include tryptophan-rich foods with other amino acids at each meal to support serotonin synthesis.
Add daily physical activity like walking, cycling, or yoga to stimulate serotonin release.
Get bright light exposure in the morning to improve mood and regulate vitamin D levels.
Support gut health with probiotic-rich foods and fiber to help the body’s serotonin neurons function effectively.
Use mindfulness practices for managing feelings of stress to protect serotonin levels and maintain a more positive mood.
Knowing when to seek professional help is important for protecting both mental health and physical health. A healthcare provider can assess serotonin levels, identify underlying mental health disorders, and recommend safe treatments to boost serotonin naturally or through medication if needed.
Persistent low mood, depressive symptoms, or loss of interest in daily activities.
Severe or ongoing feelings of anxiety, panic attacks, or other affective disorders.
Sleep problems, appetite changes, or chronic stress that do not improve with lifestyle changes.
Concerns about serotonin syndrome when using certain supplements or medications.
Need for guidance on safe use of selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors.
Supporting a healthy lifestyle does not require drastic changes. Simple, consistent habits like eating tryptophan-rich foods, staying active, getting bright light exposure, and caring for gut health may influence serotonin levels and support mood, sleep, and overall well-being.
Starting with one or two manageable changes allows you to build lasting routines that support both mental health and physical health. Even a small serotonin boost can make a meaningful difference in your daily life.
