What Is 5-HTP?

5-HTP is a naturally occurring amino acid that is usually derived from the seeds of Griffonia simplicifolia. It is commonly sold over-the-counter in the United States, United Kingdom and Canada as a dietary supplement. It’s marketed for its uses as an antidepressant, sleep aid, and appetite depressant.

5-HTP Dosage Information

It is generally accepted to start with 50mg three times per day with meals. If the patient is not getting the desired effect after two weeks, dosage may be increased to 100mg three times per day. For patients dealing with insomnia the it is recommended to start with 100mg before bedtime and up dosage to no more than 300mg if necessary. It is recommended to start with the 50mg doses as some patients experience mild nausea. [2]

How Does 5-HTP Work?

5-HTP serves as a chemical precursor and metabolic intermediate in the synthesis of the neurotransmitters serotonin and melatonin. Serotonin is a neurotransmitter and that affects sleep, mood, appetite, sexual behavior, and pain sensation. Melatonin is a naturally occurring compound that affects one’s biological sleep schedule. Having low levels of melatonin make it more difficult for one to fall asleep at night. [1]

Safety and Side Effects of 5-HTP

Mild side effects include heartburn, stomach pain, nausea, and diarrhea. Because 5-HTP increases the neurotransmitter serotonin you should consult your physician if you are currently taking any prescription anti-depressants. Taking 5-HTP along with certain anti-depressants might increase serotonin levels too much and cause serious side effects including heart problems, shivering, and anxiety.
