iHerb Customer Reviews
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!

Sometimes helps to fall asleep (1g). Tryptophan as good as other brands I tried.

O produto é de excelente qualidade e preço. A entrega demora um pouco devido aos tramites no Brasil, mas chegou bem embalado.
Just as good as prescription
Posted by MusettaRose on Jan 09, 2015
In the past I've had prescription to tryptophan, which was 3 to 4 times as expensive for me. This is just as good. I'm weaning off effexor, and I've been increasing my dose slowly with each reduction, with the help of naturalpath , to the point that I'm taking 4 tryptophan pills throughout the day, and I'm down to only 30% of my effexor pill, with absolutely no withdrawal effects!
