5-Hydroxytryptophan (5-HTP) is an amino acid that may be beneficial in treating depression, obesity and insomnia.
Woman in bed awake, suffering from insomniaTryptophan (TRP) is an amino acid (balances nitrogen in adults) that the body makes from 5-HTP. In turn, TRP is converted into serotonin, which is found in platelets (maintains homeostasis) in the brain cells and the intestine. Serotonin is an important neurotransmitter and 5-HTP helps to raise levels of this chemical in the brain. Serotonin positively affects anxiety, aggression, pain sensitivity, sleep, temperature, and sexual behavior.

Many antidepressant drugs increase the level of serotonin in the brain. These drugs are used to treat mild to moderate levels of depression thereby improving mood, reducing anxiety, and promoting ability to sleep.

Sources of 5-HTP
5-HTP is plant based and is extracted from the seed of the African plant Griffonia simplicifolia. 5-HTP is found in multivitamin formulations and herbal preparations. It is available in tablets and capsules in the following doses: 25-mg, 50-mg, and 100-mg.

Guidelines and Cautions
5-HTP may not benefit everyone who takes it.

Some sources recommend 50-mg to 100-mg of 5-HTP daily. Magnesium, niacin, and vitamin B6 assists in 5-HTP's conversion to serotonin. The effects of St. John's wort may be enhanced when combined with 5-HTP.

5-HTP should be used together with a high-carbohydrate food or liquid such as orange juice, and as part of a comprehensive nutritional program.

If you regularly take more than 300 milligrams of 5-HTP daily, you should undergo blood testing for levels of a type of white blood cell called eosinophils every three months.

5-HTP may cause the following side effects:

  • Heartburn
  • Gas
  • A full feeling
  • Mild nausea.

Do not take 5-HTP if:

  • You take antidepressants
  • Pregnant or nursing
  • Diabetic
  • Have high blood pressure

Do not give 5-HTP to children unless directed by a medical professional.
