The essential amino acid L-tryptophan helps support relaxation, restful sleep, and positive mood. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response and sleep/wake cycles. 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 capsule three times daily, between meals and preferably with fruit juice. To support restful sleep, take 3 capsules before bed.

iHerb Customer Reviews
I was depressed for about 1 year and had not medical insurance. I went into my local health food store and asked for something. I have been taking L-Tryptophan 3 xs a day for 2 months now and I can think clearer and am not crying all the time. I can get up in the morning and look forward to a day and go to bed without crying myself to sleep. I recommend this to anyone who needs something for depression.
I have suffered from depression my whole life and have been put on several antidepressants and none of them worked for me and had horrible side effects. Since I have started taking L-Tryptophan I have not suffered one day of depression. Unlike before I started taking this product I suffered from severe depression, life wasn't worth living depression. I LOVE THIS PRODUCT!!!!!!
Reduced anxiety/better sleep

I notice a difference within half an hour. Unlike some medicines, I have no annoying side effects like short term memory loss. It also reduces my tendency to ruminate for ling periods. If I use this supplement as a sleeping aide, I don't feel groggy when I wake up. Very happy with this product.
Good for sleep...

Drop 2000mg and off to bed! Simple. Why not make in 2000 or 5000mg capsules? Would be more convenient.
