5-hydroxytryptophan, also known as 5-HTP, is a dietary supplement made from the seeds of the African plant Griffonia simplicifolia.
Other uses not proven with research have included insomnia, alcohol withdrawal, headaches, premenstrual syndrome, binge-eating related to obesity, attention deficit disorder, and muscle spasms in the mouth.*
It is not certain whether 5-hydroxytryptophan is effective in treating any medical condition.*
 When considering the use of herbal supplements, seek the advice of your doctor. You may also consider consulting a practitioner who is trained in the use of herbal/health supplements.
If you choose to use 5-hydroxytryptophan, use it as directed on the package or as directed by your doctor, pharmacist, or other healthcare provider. Do not use more of this product than is recommended on the label.
Do not use different forms (tablets, liquid, tincture, teas, etc) of 5-hydroxytryptophan at the same time without medical advice. Using different formulations together increases the risk of an overdose.
Avoid using 5-hydroxytryptophan with other herbal/health supplements that can cause drowsiness. This includes California poppy, catnip, chamomile, gotu kola, Jamaican dogwood, kava, melatonin, St. John's wort, skullcap (or scullcap), valerian, yerba mansa, and others.
 Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
 Although not all side effects are known, 5-hydroxytryptophan is thought to be possibly safe when taken for a short period of time.*

 • severe tingling or numbness;

 • muscle pain or weakness.
