Source Naturals L-Tryptophan Description

Mood, Relaxation, Sleep

The essential amino acid L-Tryptophan helps support relaxation, restful sleep, and feeling better. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, L-Tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals L-TRYPOTOPHAN is extremely pure and is regularly tested to ensure the highest standards of quality.


1 capsule 3 times daily, between means and preferably with fruit juice. To support restful sleep, take 3 capsules before bed.
Free Of

Works great I used tryptophan years ago. Then they took it off the market. I am so glad it is back. I have tried lots of other products for sleep and this one works for me. I am an insomniac and this is a safe way to quickly fall asleep. No hangover feeling the next day. I trust this brand. It is gluten free and that is essential for me. June 15, 2013

natural relaxant This is a great natural takes the edge off! I have to be careful because sometimes it can make me sleepy. I take one in the morning, then take 1 or 2 at night. September 27, 2012
This is a "life saver" I have no problem going to sleep at night, but I usually wake up between 1 and 2am. Thats when I stuggle to get back to sleep. This helps me drift to sleep with NO drowiness when I have to get up! August 22, 2012
