5-Htp

How does 5-htp work?

5-HTP works by increasing the production of the chemical serotonin. Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation.

Are there safety concerns?

5-HTP might be unsafe for use. There is concern that it can cause a serious side effect called eosinophilia myalgia syndrome. Some people think this side effect is only caused by a contaminant in some 5-HTP products. But there is not enough scientific evidence to know if it is caused by 5-HTP, a contaminant, or some other factor. Until more is known, 5-HTP should be avoided.

Other potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, and muscle problems.

Do not take 5-HTP if:
  • You are pregnant or breast-feeding.
  • You have a condition called Down syndrome.
  • You are scheduled for surgery in the next two weeks.
