5.0 out of 5 stars Excellent Sleep Aid, May 30, 2007

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.

5.0 out of 5 stars A WONDERFUL, NATURAL PRODUCT, April 6, 2008

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!!

5.0 out of 5 stars Perfect sleep aid, July 4, 2007

By	ajs (southern california) - See all my reviews

I am a true insomniac who does not want to take prescription sleeping pills due to side effects and dependency issues. So I tried this. Works really well for me. Does not knock me out. Just eases me into a natural sleep. Price at Amazon is half of what I would pay at local health food store.
