L-TRYPTOPHAN POWDER
Recommended
Quality: it works great for me, I don't like the taste because it is neutral. Effectiveness: I mix it with melatonin and before in the middle of the night I would wake up and start thinking without knowing and now I do wake up and immediately go back to sleep and when you get up is when you notice that you have rested. Presentation: a lot of packaging for such a small amount of product, better in a small bottle.

VERIFIED OPINION
L-TRYPTOPHAN POWDER
Excellent before bedtime
I take it a while before going to bed and the truth is that the effects are noticeable after 20 or 30 minutes. They are similar to melatonin, although I prefer to take tryptophan directly. I notice a feeling of relaxation that helps me to sleep without tossing and turning in bed. The only downside is that it is quite difficult to dissolve it in water, but for the price I prefer to spend some time with the teaspoon rather than taking it in tablets.
