The Role of Serotonin

Serotonin is a neurotransmitter in the brain. This chemical helps to relay signals from one area of the brain to another. Ninety percent of serotonin is found in the digestive tract and in blood platelets. This chemical is believed to influence a variety of psychological and other body functions.

Significance

• Serotonin influences mood, sexual desire and function, appetite, sleep, memory, learning and temperature regulation. Serotonin also influences heart function, muscles and elements in the endocrine system.

Theories/Speculation

• Blood levels of serotonin are lower in people who are suffering from depression. Doctors are not sure if low levels of serotonin cause depression or if depression causes levels of serotonin to drop.

Considerations

• Serotonin is made from tryptophan. Tryptophan is an amino acid that converts into serotonin.

Foods to boost seratonin

• Protein-rich meats, chicken, dairy products and nuts eaten along with carbohydrate-rich foods can help boost serotonin. Carbohydrates release insulin, which keeps tryptophan in the blood where it can enter the brain.

Vitamins

• Vitamin B6 helps tryptophan convert into serotonin.

SSRIs

• Selective Serotonin Reuptake Inhibitors (SSRIs) are prescribed for mental health conditions. The use of SSRIs is believed to work by influencing mood, outlook and behavior.
