Good formula, decent price.

Addition of B6 and other co-factors makes this a good tryptophan formula in my opinion.

L tryptophan

I haven't tried this alone with no other sleep aids, so I do not know how much it is helping yet. I would try it again, though.

Standard - does what normal HTP5 does. Caution against taking too much before bed as it will give me a drowsier than normal morning + v v v vivid dreams.

i didn't feel much of an effect from these. i feel kinda jealous of people who write about walking into paradise garden after taking it or something. i also give one tablet to my boyfriend in the morning before work and i think there were some improvements in his mood since he was stressed at work.

Jarrowのカプセルと比較すると効きが悪いです。2~3倍以上の量が必要になる上に効果が低い。 Jarrow is better for tryptophan.

It has nothing to do with this specific product cause i believe any other tyrptophan product will make me feel dizzy heavy and severly depressed. I myself have some liver inflamation so it might be that tryptophan clearance in my case is defected and thus i feel bad with it. But i read at the internet that it may have many adverse effects on healthy people too and i'm not sure it is a good idea to use trypthopah products from what i read, no matter who is its vendor. Use the internet to learn more about tryptophan supplements to be aware of its possible side effects.
