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!!

Source Naturals L-Tryptophan has performed miracles for me. It's an amino acid that helps build the brain's feel-good chemical, serotonin. I've used it for about 2 years after reading The Mood Cure: The 4-Step Program to Take Charge of Your Emotions--Today for its nutritional advice, upon the recommendation of this book: Protein Power: The High-Protein/Low-Carbohydrate Way to Lose Weight, Feel Fit, and Boost Your Health--in Just Weeks!.

I was shocked by the difference it made for me in the quality and quantity of my sleep. I'd spent the last year or two waking up, wide awake, at 3:30 in the morning & was unable to go back to sleep. I take 1500 mg of Tryptophan (3 500 mg capsules) and 400 mg of chelated magnesium before bed and now enjoy deep and restful sleep. [I've recently added in another supplement, melatonin; you can read more about that at the end of this review].

I find that I am more resilient, resistant to stress, & easygoing since taking tryptophan.

I experienced its incredible mood-boosting effect earlier this year after enduring a ruptured appendix. I suffered several complications & had to be put on super strong antibiotics that depleted all my B Vitamins and sent me into a quick but INTENSE bout of post-surgical depression (much like what heart bypass surgery patients experience, according to my surgeon). I spoke with my physician to get his approval, then took just 500 mg of tryptophan that afternoon and then 1500 at bedtime, as usual, and bounced back to my usual cheerful self within JUST 2 DAYS.

Just a suggestion--be sure you're taking it on an EMPTY stomach (about 1-1/2 hours after eating anything).

This is an amino acid & any trace of protein in your stomach will compete with the tryptophan. Don't take with milk; take with water (some experts suggest a couple of sips of apple juice--but I use H2o).

If 3 capsules at bedtime (or an hour before) on an empty stomach won't do the trick after a few days, then it's possible you aren't low on serotonin. If you awake groggy, you're taking too much.

Here's something else that works: 400 mg of CHELATED magnesium (not just magnesium oxide, make sure it is chelated magnesium); the best I know of is this one: Chelated Magnesium 200mg - 180 - Tablet. Works wonders for sleep and health; most Americans' magnesium levels are chronically low, which can lead to heart issues and other preventable diseases. Get this book to learn more: The Magnesium Factor.

Hope this helps someone out there; I wish I'd known about tryptophan 10 years ago!

P.S. For hardcore insomniacs for which tryptophan won't do the trick (give it time & remember to take on an empty stomach), try some melatonin; read my review of this product for more detailed info: Source Naturals Melatonin Complex Sublingual Peppermint, 100 tablets (Pack of 2)

****UPDATE P.S. Also, please remember that supplements work slowly, over time. Metabolisms vary. Educate yourself; I highly recommend you start with The Mood Cure: The 4-Step Program to Take Charge of Your Emotions--Today to quickly "zero in" on your own personalized needs. Good Health (and good sleep) to All!

I come from a long line of semi-insomniacs and have always had difficuly falling asleep and remaining so without waking up every hour or two. Since I have been taking 3 capsules of the tryptophan before bed I have been sleeping like a baby everynight and feel much more refreshed and rested during the day.

Made no difference to my hapless sleep pattern - I had high hopes after reading the reviews but found it didn't work for me - my husband and I shared the bottle and he sweetly suggested it 'might' have made a difference.

Previously I had been taking 5htp supplements for for suspected low serotonin levels. The 5-htp didn't seem to have much effect beyond placibo, so I switched to a prescription L-Tryptophan, 1000mg on an empty stomach before bed. This had a definite effect and I was happy.

While browsing Amazon one day, I came across Source Naturals L-Tryptophan and noticed how well reviewed it is. I purchased a bottle and switched to Source Naturals 1.5g a night, the day it came in. That night I had some of the most restful sleep I have ever had. I also had some amazing dreams.

The day after first switching over to this product colours were brighter, food tasted better, I was happier and breathing more deeply. This product has made a significant positive impact on my life! I will continue to keep taking Source Naturals L-Tryptophan because it has proven to be much better than any other products I have tried!

I usually take three tablets (the recommended dosage) an hour before bed, and I sleep deeply. Not to mention, I have the wildest, most phantasmagoric dreams from l-tryptophan. These might be quite useful to people trying to lucid dream.

A bottle of 60 caps lasts me around a month and a half, although that's because I take it 3 times a week to sleep up for school. Also, it is not a good idea to take MAO inhibitors in conjunction with this. Sometimes Kava Kava will do the trick and Gaia Herbs "Serenity" is great too, but l-Tryptophan has been most effective for me.

Update: I have tried both the tablets and the capsules, and have found the tablets more effective. The capsules might as well be a placebo, which the tablets make me undeniably sleepy.

This helps me to fall asleep quickly and easily without druggy side effects. If anything I just feel calmer through the next day.

The illustration for this product shows a bottle of tablets though it is, in fact, capsules. The capsules are MUCH bigger than the tablets, which are somewhat more expensive. Both are highly effective sleep aids and I have found Source Naturals to be the most effective brand.
