5-HTP Extended Release by Seeking Health provides natural L-5-hydroxytryptophan (5-HTP) extracted from the seeds of the Griffonia plant. 5-HTP is not found in significant amounts in a typical diet. The human body manufactures 5-HTP from L-tryptophan, a natural amino acid found in our diets. However, eating food that contains L-tryptophan does not significantly increase 5-HTP levels, because L-tryptophan may be diverted to other functions, such as niacin production. 5-HTP is a precursor to brain neurotransmitters which are important for emotional well-being. Neurotransmitter levels in the brain are highly dependent on the availability of 5-HTP within the central nervous system. 5-HTP can cross the blood-brain barrier without the requirement of a transport carrier.*

Neurotransmitters control major body functions including movement, emotional response, and the physical ability to experience pleasure and pain. These functions also include the appetite center of the brain. 5-HTP may help support a healthy appetite and healthy sleep. Adequate neurotransmitter levels play a significant role in melatonin production, the hormone responsible for regulating biological rhythms, such as sleep.*

This extended release version of our popular 5-HTP products provides a higher dose of 5-HTP - 200 mg per tablet - designed to release slowly over a few hours. For a lower dose product or a faster release delivery method, consider our 5-HTP Lozenges or our 5-HTP Capsules.

A friend recommended me to try 5HTP and it has been wonderful
I suffer from clinical depression so I was looking for a natural supplement to take rather than antidepressants. A friend recommended me to try 5HTP and it has been wonderful! I take 2 daily in the morning and I feel balanced all day. Taking 5HTP while on a healthy diet and workout plan has improved my life so much! Review by Alexa (Posted on 4/18/2018)
Controls apetite
Helps me to have very calm energy all day long. I am premenopausal but with dropping progesterone. Was recommended by dr. But what I like best is that it controls a bit of stress eating I was doing. Review by HealthNut (Posted on 11/14/2017)
Love it!
Ever since taking this product with Seeking Health L-tyrosine, I have been significantly more mentally stable. So I don't know if my improvement is due to switching from a store-bought brand of 5-HTP to this product, or if it's adding the L-tyrosine (I was told they should be taken together, but not at the same time).
