From the Research

5-HTP should be used with caution and under the guidance of a healthcare provider, as its effectiveness varies and it can interact with other medications, particularly SSRIs, increasing the risk of serotonin syndrome 1. When considering the use of 5-HTP, it's essential to weigh the potential benefits against the risks. 5-HTP is a dietary supplement that may help with mood, sleep, and certain types of pain by increasing serotonin levels in the brain. A typical dosage ranges from 50-200 mg per day, taken 1-3 times daily, often 30 minutes before meals or at bedtime for sleep issues. Start with a lower dose (50 mg) and gradually increase if needed. Some key points to consider:

  • 5-HTP works by converting directly to serotonin in the body, bypassing the rate-limiting step in serotonin production.
  • While some people find it helpful for depression, anxiety, insomnia, fibromyalgia, or migraine prevention, scientific evidence for its effectiveness varies 1.
  • Important precautions include avoiding 5-HTP if you're taking antidepressants (especially SSRIs or MAOIs) due to the risk of serotonin syndrome, a potentially dangerous condition 2, 3, 4.
  • Side effects may include nausea, digestive issues, and drowsiness.
  • Consult with a healthcare provider before starting 5-HTP, especially if you have existing health conditions or take medications. It's crucial to prioritize caution when using 5-HTP, especially in combination with other medications, to minimize the risk of adverse effects and ensure the best possible outcome in terms of morbidity, mortality, and quality of life.
