This is the exact pharmaceutical quality product as was available only by prescription after the "tryptophan scare," and MUCH less expensive.

Since I increased my intake of Tryptophan to two caps at night, I've been feeling noticeably better and more energetic during the day!

After struggling for years with insomnia, I can't believe how well I sleep when I take this along with Melatonin. Now, I did read that Niacin and B-6 help the body assimilate the tryptophan, so I've been also taking one capsule of "True Calm". However, recently, I found that iHerb also carries this brand of tryptophan with the niacin and B-6 already included, so I am planning to try that.

Better than sleeping pills in helping me get to sleep. Don't leave me feeling groggy, even if I take them at 5 a.m. for another couple of hours sleep.

At age 51, I have had trouble sleeping. I tried taking two of the L-Tryptophans and they worked like a charm. No hangover just solid sleep! Yehaa!
