- 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-Tryptophan is extremely pure and is regularly tested to ensure the highest standards of quality.
1 tablet three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 tablets before bed.

iHerb Customer Reviews
A night's sleep without L-Tryptophan isn't a Good night's sleep. I'm 58 and have been getting a normal night's sleep for about five years now, since I started supplementing with tryptophan. One 500mg tablet when I'm ready to fall asleep is all I need (actually I take about 0.25mg melatonin along with it[and sleep like a baby])
I have used this product along with iodine drops for depression and they are awesome I think anyone who suffers from depression should seriously consider this product.

This product is wonderful, it helps relaxes you and since I have been taking it I now fall asleep much more easily and stay asleep. I don't wake up in the morning feeling drugged up, there are no side effects and it is a wonderful supplement. I will continue to use this product, and recommend it to my friends to try. Ann

Took 1000mg before bed for 4 days and experienced severe muscular pain after about 3 days, I stopped using Tryptophan right away. Now, 10 days later and the pain persists and is continuing to get worse. Do intensive research before taking this supplement.
