safe & effective

By increasing seratonin levels in the brain, L-Tryptophan is a safe and effective aid for sleeping and mild depression. It is best used at bedtime on an empty stomach, preferably with a small serving of carbohydrates (I take a sip of orange juice). Start with one per night and work up to three if necessary.

I use to take tryptophan years ago for sleep ,it allawys worked great. Recently tried Jarrow L- Trypto. Made me sleep through the night but feel druged for half the next day, I mean bad ,like poisoned. no matter what time of day I take it with or without food same result. Don't know if the formula has changed or its some change in my chemistry.

Knocks me out

Posted by Reviewer1075233 on Jan 10, 2010

Purchased at iHerb

In terms of any kind of insomnia, one pill will knock me out quickly, surprising how fast. However the next day I feel very heavy, a little drowsy, and a bit foggy through the morning. I havn`t noticed any kind of `mood enhancing` effect, but the physical heaviness I get the next day prevents me from being in much of a good mood. I was interested in this primarily to aid with depression, but it makes me way too tired/heavy to be taken regularily and function mentally at 100%.

One of the Best Tryptophan products on the Market!!

I have used Tryptophan for years and Jarrow is one of the best brands I have used! Ajinomoto is the company to look for! I tried a less expensive brand with another type of Tryptophan and was not nearly as happy with it as I am with this product. Just so people know Tryptophan is a pre-curser to Melatonin. If you take B-6 with Tryptophan and some juice or sugar it will convert to seratonin and finally to melatonin. Tryptophan is used for sleep aid, depression, and pain relief. As odd as it may sound Tryptophan does help reduce pain, can help lower the incidence of Migraines as well. The dose depends on the person. For me, 3 work great. I have tried Melatonin with Tryptophan and it makes me too drowsy the next day. This is a wonderful product delivered the next day!! Thanks iherb!!
