There is a growing interest among scientists in the idea that gut microbiota might influence the nervous system - including behavior, mood, and thinking - through a link known as the gut-brain axis. Learn more about foods that may help boost serotonin levels here. People should speak to a doctor before using any supplements, in case there is a risk of adverse effects. In one study, a number of older people improved their scores on cognitive tests after taking tryptophan supplements for 12 weeks. In addition, the amount of tryptophan in foods may be too low to make a difference.īananas contain serotonin, but they can only improve a person’s mood if the serotonin they contain will reach the brain. Eating foods that contain tryptophan may help support this process, but it does not mean that the body will necessarily absorb and use it. The body uses tryptophan to create serotonin. Some research has linked higher intake of dietary tryptophan to more positive mood scores, possibly because tryptophan bolsters serotonin levels.įoods that may contain tryptophan include: Tryptophan is an amino acid that occurs in some foods. The FDA require all antidepressants to carry a black box warning about the danger of suicide during the initial stages of treatment, especially in people aged under 25 years. Anyone experiencing thoughts of suicide should seek help at once. At first, symptoms may worsen before improving. SSRIs and suicideĪ person who uses SSRIs for depression will not experience the benefits at once. Learn more about serotonin syndrome here. This is a potentially life threatening condition that may require emergency treatment. Rarely, taking too much of a drug that boosts serotonin levels or combining two such drugs can lead to serotonin syndrome. SSRIs have some side effects, but these usually improve with time. Learn more about SSRIs and other antidepressants here. SSRIs that have approval from the Food and Drug Admi nistration (FDA) for treating depression are: Serotonin levels remain high in the brain, and this may elevate a person’s mood. SSRIs increase serotonin levels by preventing the body from reabsorbing serotonin neurotransmitters.

Other disordersĪpart from depression, doctors may prescribe drugs that regulate serotonin levels to treat a number of other disorders, including:Īs with depression, some scientists have questioned whether serotonin is the only factor impacting these conditions. Nevertheless, if scientists have not yet proven the serotonin theory of depression, SSRIs do appear to help many people. In 2015, one editorial called the use of SSRIs to treat depression “the marketing of a myth.” Some suggest that increasing serotonin levels can help reduce stress and depression, but others indicate that serotonin levels make no difference. Mouse studies have produced conflicting evidence. It is also impossible to know whether SSRIs can really affect the brain. One problem for researchers is that, while they can measure serotonin levels in the bloodstream, they cannot measure its levels in the brain.Īs a result, they do not know whether serotonin levels in the bloodstream reflect those in the brain. Many people find SSRIs help relieve their symptoms, although the link between depression and serotonin remains unclear. SSRIs stop the body from reabsorbing serotonin, leaving higher levels of serotonin to circulate.
Normally, the body reabsorbs a neurotransmitter after it has transmitted its neural impulse. Scientists do not know precisely what causes depression, but one theory is that it stems from an imbalance of neurotransmitters in the body.ĭoctors commonly prescribe selective serotonin reuptake inhibitors (SSRIs) as antidepressants. This could have implications for the treatment and prevention of various physiological conditions, such as bone degeneration. However, research suggests that sources of serotonin in other areas, such as the digestive system, may work independently of serotonin in the brain. Treatments for depression and other mental health issues do not supply serotonin directly but trigger reactions that can boost serotonin levels in the brain. This means that the brain must produce any serotonin that it needs to use. Serotonin cannot cross the blood-brain barrier. For this reason, some people have looked at food as a possible source of serotonin. Serotonin is also present in animals, plants, and fungi. Occurring throughout the body, it appears to influence a range of physical and psychological functions.
It is also present in blood platelets and plays a role in the central nervous system (CNS). The intestines and the brain produce serotonin. Serotonin is a result of tryptophan, a component of proteins, combining with tryptophan hydroxylase, a chemical reactor. Share on Pinterest Image credit: Klaus Vedfelt/Getty Images.
