NOW Foods L-Tryptophan 500mg,120 Vcaps, 120 grams

Works as expected. Make me sleepy immediately after taking suppliment. Good mood and appitite control as expected

It really worked for my anxiety, irritations. I am calmer now. And not stressing over same topic in my head. Along with modifying to a healthy lifestyle and shifting yourself from negative environment,take one tablet on alternative days. Also do not stop abruptly. Increase the gap between days before stopping completely. It will help

Really helps with the depression/negative mood . This simple improvement in mood and feeling positive has great implications in day to to day life eventually leading to things overall looking upwards !

I felt the Quality was good enough / satisfactory. but in terms of pricing, I am not aware of any place where it is cheaper. but for me personally, it was worth the buy!

Useless. Ineffective.

Very expensive.. its available at various websites at half the price. Its not returnable also. Do not buy. Four thousand is way too much

This caused a serious side effect in my son. About 1 hour after taking it he had severe back muscle stiffness and he couldn t bear the pain. Even with a muscle relaxant it took him 3 days to feel normal . Suggest not to be taken without doctor s supervision . Also the seller didn t take the product back after bringing to their notice , the side effect .
