We have been using this for insomnia for several years now. It seems to be a high quality product and works well.

I've used this brand and the NOW brand and the Jarrow Brand - they all seem to work for me about the same - which is very well. I really like taking it to help me fall asleep. And I think it helps me stay asleep better - although there are nights when I still wake up for no reason! I love my tryptophan!

I like to use Tryptophan for sleep & have needed to use it instead of Niacin since my stomach has become too sensitive for niacin. I use 3 capsules a night, along with chelated magnesium and melatonin. Sleep like a baby and this helps keep serotonin levels up so you can stay your happy self as you age. Highly recommended!

Good product. They recommend 3 at bedtime, but I find 2 works fine.
