5-HTP is produced as a protein building block L-tryptophan. It can be used to treat depression and fibromyalgia, and there is little evidence that it can be used to treat other health issues, such as Alzheimer's, anxiety, nervous system disorders, headache, menopausal symptoms and more.

According to WebMD,EMS is a more serious side effect that is often associated with the use of5-HTP. Some experts connect the use of 5-HTP with EMS due to some ingredients that are found in 5-HTP, such as contaminants. These contaminants are found in certain 5-HTP products and not in others. While this connection with EMS has not been fully proven, it is recommended to take the necessary precautions when taking5-HTP. Those with Down syndrome should take precautions with 5-HTP, because it has been linked to possible seizures.
