Reviewed in the USA on 2010-11-28T16:00:00

. I HAD RUN OUT AND WAS HAVING TROUBLE SLEEPING FOR A COUPLE WEEKS. AS SOON AS I STARTED TAKING THIS AGAIN, I SLEEP VERY WELL.7 TO 8 HOURS OR MORE MOST NIGHTS. TAKE WITH B COMPLEX AND NOTHING EXCEPT WATER.

One of these at bedtime helps keep my mood elevated and also helps me sleep. I used to take the 500mg tablet, twice a day, but it is easier, for me, to just take this at bedtime.

This seems to be more effective for sleep than Melatonin.

The wife takes this product on a regular basis and seems very pleased with the results. When she gets down to a dozen or so caplets she always reminds me that it is time to re-order. Overall, I am very pleased that this product has been made available by Swanson's. A name that I have come to completely trust for a quality product at a fair price.

I have to take 2 of these, but they do work for sleep. I will occasionally get up in the night if I have to, but I can usually fall quickly back to sleep. I've already purchased 2 bottles of this from Swanson and I plan to order more. Can't beat the price! :)

Swanson brand L-Tryptophan

Reviewed in the USA on 2012-10-21T17:00:00

I substituted this brand of L-tryptophan because you were temporarily out the "Swanson" brand that I have been purchasing over 2 years. This brand had no effect on me and now I am stuck with it. What a waste of money. i hope you have the Swanson brand that I am used to real soon. Jean Stachon

Didn't Like

Reviewed in the USA on 2013-02-05T16:00:00

For some reason Now's 1,000 tablet form did not work for me. I normally use Now's 500mg CAPSULES and these work great for me (as expected). It was horrible not having the effective Tryptophan in my system that I'm used to. Since many people like this product it's obvious different formulas work differently for each person. If you're new to Tyrptophan be sure to find what works for you. I've used Tyrptophan for over 5 years, and with both Swanon's and Now 500mg CAPSULES I get great results, and those effects where felt in just three days. This product fell completely flat for me even the next day.
