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