This is truely a great supplement for people who need to restore their sleep patterns or just want more restfull sleep. It also helps out with the overall feeling of well-being.

Works great. I use vitamins b6,amino acid lysine, niacin and some sleepy herbals with it. Seems like I dream more. Will reorder often.

I used this instead of 5-htp for a week. Depression crept in, so I switched back to 5-htp. Will try it again during less stressful times. Tryptophan is supposed to be safer in the long term than 5-htp. The stuff is bitter, and fly away powdery. This is the only brand I have tried.
Works well but...

It works well but it's a little bitter so you really need to mix it into apple sauce or something w/similar texture if you don't drink fruit juice. I'm going to put the rest into my capsule maker.

I wasn't paying enough attention when I ordered this product. Previously I've ordered from you, and used Doctor's Best L-Tryptophan Powder USP Pharmacetical Grade 100 grams. The price was similar, and I use a similar amount each night. Therefore, I am paying about twice as much for the new to me product. I hope that in the future you will again offer the 100-gram product.

Seems to help me sleep. It doesn't dissolve as well as I would like in water. I will try it in a warm liquid in hopes that will work better.
