What You'll Learn
Eat tryptophan-rich foods like eggs, cheese, turkey, salmon, and tofu
Tryptophan is an amino acid that is necessary for human nutrition and physiological functions. It is the precursor to serotonin, a neurotransmitter that regulates mood, sleep, and appetite. Serotonin cannot be obtained directly from food, but tryptophan can, and it is found primarily in high-protein foods.
Eggs
Eggs are a great source of protein and contain high levels of tryptophan. Research suggests that the protein in eggs can significantly boost your blood plasma levels of tryptophan. Be sure not to leave out the yolks, as they are particularly rich in this amino acid.
Cheese
Cheese is another excellent source of tryptophan. Combining cheddar cheese with eggs and milk, as in a mac and cheese dish, can provide an extra boost of tryptophan.
Turkey
Turkey is well-known for its tryptophan content, and consuming it is believed to promote sleepiness. However, many other foods contain as much or more tryptophan as turkey and do not have the same association with drowsiness.
Salmon
Salmon is a tryptophan-rich oily fish that also provides omega-3 fatty acids, which are important for strong bones, healthy skin, and eye function.
Tofu
Tofu is a soy product and an excellent source of tryptophan, especially for vegetarians and vegans. It can be used as a substitute for animal protein in various dishes.
It is important to note that while these foods can boost serotonin levels, they should be combined with carbohydrates to maximise tryptophan's effectiveness in reaching the brain. Additionally, a healthy gut is vital for serotonin production, so including prebiotic and probiotic-rich foods in your diet is beneficial.

Combine protein-rich foods with carbohydrates
Serotonin is a chemical messenger that boosts your mood. While it is possible to get serotonin from food, it is a bit tricky. Tryptophan is an amino acid that is important for serotonin production in the body, and it can be obtained from food. However, eating tryptophan-rich foods does not guarantee that it will enter your brain and be converted to serotonin.
Protein-rich foods such as turkey, salmon, and eggs are high in tryptophan. However, when you eat protein-rich foods, the protein breaks down into amino acids, which compete with tryptophan to cross the blood-brain barrier. As a result, less tryptophan reaches the brain.
One way to increase the chances of tryptophan reaching your brain is to consume it with carbohydrates. Carbohydrates cause the body to release insulin, which helps muscles absorb more amino acids, giving tryptophan a better chance of reaching the brain. Therefore, combining protein-rich foods with carbohydrates may help boost serotonin levels.
- Include a protein source with your carbohydrates during dinner, such as having grilled vegetables with tofu or salmon.
- If you are a vegetarian or vegan, soy products such as tofu and soy milk are excellent sources of tryptophan. You can easily substitute tofu for any protein and combine it with carbohydrates.
- Eggs are another good source of tryptophan. You can combine them with carbohydrates such as toast or hot cereal for breakfast.
- Nuts are a good source of protein and healthy fats. You can snack on a handful of nuts with some dried fruit or pita bread.
- Dairy products such as milk and cheese are also good sources of tryptophan. You can include them in your diet by making mac and cheese or a frittata with vegetables.
It is important to note that while combining protein-rich foods with carbohydrates may help boost serotonin levels, it is not the only factor involved in serotonin production and mood regulation. Regular exercise, a healthy gut, and adequate sleep also play important roles in serotonin levels and overall well-being. Additionally, if you are considering taking tryptophan supplements, it is recommended to consult a healthcare professional first.

Consume probiotics and prebiotics for good gut health
Serotonin is a neurotransmitter, or chemical messenger, that plays a role in regulating mood, promoting smooth digestion, and influencing various physiological processes. While serotonin itself cannot be obtained directly from food, consuming probiotics and prebiotics can promote good gut health and support serotonin production.
Probiotics are live microorganisms that offer health benefits to their host. Research has suggested that certain probiotic strains, such as Lacticaseibacillus rhamnosus and Limosilactobacillus reuteri, are associated with higher intestine serotonin transporter (SERT) concentrations. Probiotics have been found to promote serotonin signaling, which is crucial for mood regulation, cognition, and other physiological functions. Additionally, probiotics can influence serotonin levels in the brain through various mechanisms, including serotonin production in the gut, modulation of SERT, immune system interactions, and the production of metabolites like short-chain fatty acids (SCFAs).
Prebiotics work synergistically with probiotics to support gut health and serotonin regulation. Research has shown that both prebiotics and probiotics exhibit antidepressant effects and positively influence serotonin metabolism. Specifically, prebiotics can help ameliorate depressive-like behaviors and balance serotonin levels in the body.
To incorporate probiotics and prebiotics into your diet, consider consuming probiotic-rich foods such as yogurt, kimchi, sauerkraut, and other fermented foods. Prebiotic sources can include fructo-oligosaccharides and galacto-oligosaccharides, although these are often supplemented alongside probiotics in foods or dietary supplements.
By including both probiotics and prebiotics in your diet, you can promote a healthy gut microbiome, which is essential for optimal serotonin production and overall well-being. It is also important to limit foods that negatively impact gut bacteria, such as artificial sweeteners, trans fats, and processed or refined sugars.

Limit artificial sweeteners, trans fats, and refined sugars
Serotonin is a chemical messenger that's believed to elevate your mood. While there are no direct sources of serotonin in food, it can be obtained from tryptophan, an amino acid converted to serotonin in the brain. A healthy gut is vital for serotonin production, and certain foods can negatively alter gut bacteria, hindering serotonin production.
Artificial sweeteners, for example, may impact gut microbiota and function, altering intestinal glucose absorption and postprandial glucose levels. They offer less reward compared to natural sugars, potentially driving increased food-seeking behavior and energy intake. Additionally, the safety and health benefits of artificial sweetener consumption are still debated.
Trans fats, often found in processed and refined foods, can also negatively affect gut bacteria. While trans fats occur naturally in some foods, such as dairy and meat, most trans fats in the modern diet are artificial, created through food processing. These artificial trans fats can have adverse health effects, including an increased risk of heart disease and inflammation.
Refined sugars can also disrupt gut bacteria. The intake of sugar contributes to the overall energy density of diets, promoting obesity and cardiometabolic complications. Thus, limiting artificial sweeteners, trans fats, and refined sugars is crucial for maintaining a healthy gut and supporting serotonin production.

Exercise outdoors to boost serotonin and endorphins
Exercise is a great way to boost serotonin and endorphins, and taking your workout outdoors can amplify these effects. Serotonin is a neurotransmitter, or chemical messenger, that is believed to elevate your mood and promote smooth digestion. Endorphins are also neurotransmitters, but they act as the body's natural painkillers and mood elevators.
Exercising outdoors can be an effective way to increase serotonin and endorphins in the bloodstream, thereby improving mental health. Sunlight stimulates the production of serotonin and endorphins, and spending time in nature has been shown to increase serotonin levels. Vitamin E, found in sunlight, also stimulates the production of these chemicals in the body.
To increase serotonin and endorphin production, try to exercise at least 20-30 minutes, three times a week. These workouts should be strenuous enough to push your body to a safe limit. Once the hormones kick in, you will experience improved mental clarity and a sense of accomplishment.
There are many forms of exercise that can boost serotonin and endorphins. Cardiovascular and aerobic exercises are great for creating the intensity required for endorphin release. Examples include jogging, swimming, cycling, brisk walking, and gardening. High-intensity interval training (HIIT) classes or periodic group hikes or bike rides can also be effective. If you enjoy sports, joining a local league to play soccer, basketball, or tennis can provide social interaction while giving you a cardiovascular workout.
In addition to these more intense forms of exercise, activities like yoga, tai chi, and meditation can provide physical and emotional relief. These practices can reduce depression, anxiety, stress, and mood disturbances, while also improving self-esteem and immune function.
