I can feel the difference, and yes it put me to sleep fast! However, I ordered it for Depression, and I can say, I feel a difference in how I feel, not so weighed down, and I am being more productive.

Thanks for your feedback!

Pure and greatly effective.

My favourite supplement! L.E.F is my favourite brand. No added extra ingredients, works like a dream. Like with all other supplements, I double each dose or triple the dose to be quickly effective.

Thanks for your feedback!

great product to reduce inflammation and relax. No magnesium stearate in it too which is good news as Magnesium stearate and stearic acid kills your T-cells.

Thanks for your feedback!

Effective sleep aid

This brand of L-Tryptophan is very effective. I usually take 2 to 3 capsules of L-Tryptophan with my herbal sleep supplements (e.g. valerian, lemon balm, L-theanine or a combination) and I fall asleep much faster . If nothing seems to help with one's sleep, try adding L-Tryptophan. Take it on an empty stomach or with some fruit juice to enhance absorption. I personally took it on an empty stomach.

Thanks for your feedback!
