Product Description

Package Quantity: 1 | Size: 120 Capsules

Dietary supplement. 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. (These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.) Hypoallergenic: Contains no yeast, dairy, egg, starch, salt, preservatives, or artificial color, flavor or fragrance.

5.0 out of 5 stars Sleeping better AND feeling better!, January 28, 2012

I love this supplement so much because it not only helps with my insomnia (life-long insomniac here!), but it also has a noticeable affect on my anxiety levels. I've never been diagnosed with any type of anxiety order, although I do feel many of the symptoms and have been known to have panic attacks for no good reason at all. Since I started taking Source Naturals L-Tryptophan 500mg, 120 Capsules and 10 Grams Melatonin 99% Bulk Powder, this has no longer been the case. I sleep through the night, well most nights, and I haven't had anything that even closely resembles a panic attack for close to a over a year.

The Maltonin and L-Tryptophan have been the key reasons for this, and I can't begin to say enough good things about them. I think I've taken every variety of sleeping pill in the past, all of them always giving me groggy feeling in the morning, not so with these supplements what-so-ever I go to bed and drift into a peaceful sleep within 30 minutes and wake up feeling refreshed and ready to face the day with a positive outlook on things (not something I'm usually known for saying!).

I am a shift worker. At 68 I sleep days and work 10-12 hour shifts at night. I live downstairs from very active and noisy neighbors. The major issue is of course uninterrupted sleep. I use a variety of products to help me sleep through the day and get 7 or more hours of sleep. This additive immediatly contributed to a sounder sleep. It has become a crucial weapon in my sleep arsenal.

Source Naturals L-Tryptophan, 500 mg, Tablets, 120 tablets I have suffered from insomnia since I was about 11 years old and am now 40. This is the only natural product that I have tried that works! It is not an instant fix rather, it's a cummulative effect. I guess that I really began to notice it's benefits after about one month.

I also have some anxiety and nervousness so the dose that seems to work best for me is 2-4 tablets in the morning and 4 at night. I feel less anxious and more peaceful throughout the day and actually sleep at night, without worrying about becoming dependent on a chemical sleep aid or anxiety medicine. I highly recommend this product!!
