Serotonin functions as both a neurotransmitter and a hormone. Serotonin performs a number of important functions in the body, including influencing learning and memory, as well as happiness, and regulating temperature, sleep, sexual behavior, appetite, ect. It is believed that diseases such as depression, anxiety, mania, and others might be caused by insufficient levels of serotonin in the body.

The majority of serotonin that is discovered in your body is located in your gastrointestinal tract (intestines). The cells that line your digestive tract are home to approximately 90 percent of your body's serotonin. It is then carried into your bloodstream by platelets, where it is taken up by them. Your brain is only responsible for producing roughly 10% of the total.

Tryptophan, an important amino acid, is broken down into serotonin in the body. Essential amino acids are those that cannot be produced by the organism on their own. It can only be obtained by the consumption of specific foods. In your body, serotonin is involved in a wide variety of processes. It is commonly referred to as the "feel good" chemical that is naturally produced by your body. When your serotonin levels are normal, you have better attention, emotional stability, and happiness, and you also feel calmer. Depression is linked to low levels of the neurotransmitter serotonin. Increasing the amount of serotonin in the brain is a common target for treatment in a number of antidepressants, antianxiety drugs, and other treatments used to treat anxiety, depression, and other mood disorders.

The majority of the serotonin in your body is located in your gastrointestinal system, where it helps control the function of your bowels and plays a role in protecting your gut. The serotonin release in your gut can be increased, which can speed up digestion and help your body get rid of meals or goods that are irritating to it. In addition, serotonin plays a role in suppressing your hunger while you are eating.

Nausea is brought on when serotonin is released into your gut at a rate that is faster than it can be absorbed. This can cause nausea. The chemical communication is received by your brain, and you have the sensation that you are about to throw up. The specific serotonin receptors in your brain are the target of a number of medications that are used to alleviate symptoms of sickness and vomiting. The quantity and quality of your sleep is influenced by a number of neurotransmitters, including serotonin and dopamine, amongst others (how well and how long you sleep). In addition, the production of melatonin, the hormone that controls your sleep-wake cycle, requires serotonin to be present in your brain.

Healing of wounds occurs as a result of platelets in your blood releasing serotonin. Platelets are responsible for the release of serotonin. Additionally, it causes the smallest blood vessels, known as arterioles, to constrict, which decreases blood flow and contributes to the formation of clots. The healing of wounds relies heavily on this particular process.

Bone density may be influenced by serotonin levels, which is important for overall bone health. It is possible that having high levels of serotonin in your gut plays a role in weakening your bones, which in turn can lead to bone breaks (fractures) and osteoporosis.

Serotonin, in addition to the neurotransmitter dopamine, is involved in the urge to engage in sexual activity, which is important for sexual health. Low serotonin levels have been linked to a variety of mental and physical health concerns, including depression and other mood disorders. Including Anxiety, sleep issues, Digestive issues, Suicidal conduct, Obsessive-compulsive disorder, post-traumatic stress disorder, Panic disorders, Schizophrenia, certain Phobias, ect. In most cases, a low serotonin level can be attributed to more than one factor. Your body is not manufacturing a sufficient amount of serotonin, which is the root reason for your low serotonin levels. Your body is not making good use of the serotonin it has. This may occur if your body does not produce enough serotonin receptors or if the receptors do not function as effectively as they should.

To increase serotonin, eating more meals rich in tryptophan is one of the ways that serotonin levels can be raised, getting more sunlight, taking dietary supplements like Tryptophan, probiotics, and SAMe. Or herbal supplements like ginseng, St. John's wort, Syrian rue, and nutmeg , increasing the amount of physical activity, eating food known to boost serotonin levels like tryptophan like eggs, cheese, turkey, tofu, pineapples, seeds, nuts, oats etc. Getting more sunlight and exercise. Engaging in regular physical activity can raise serotonin levels. Improving one's mood disorders and cardiovascular health can be accomplished by performing thirty minutes of aerobic exercise five times per week in addition to two sessions of strength training per week. When there is an abnormally high quantity of serotonin in the body, a condition known as serotonin syndrome can develop. Increasing the dosage of a medication that is known to raise serotonin levels or taking another treatment that is known to increase serotonin levels typically results in this side effect. Shivering, heavy sweating, confusion, restlessness, rising blood pressure, muscular twitching, and diarrhea are all examples of mild symptoms. Seizures, fainting, irregular heartbeat, and high fever are examples of severe symptoms. Serotonin syndrome can be fatal if it is severe, if it is not detected early, and if it is not treated fast.
