    Just as good as prescription

    Posted by MusettaRose on Jan 09, 2015

    In the past I've had prescription to tryptophan, which was 3 to 4 times as expensive for me. This is just as good. I'm weaning off effexor, and I've been increasing my dose slowly with each reduction, with the help of naturalpath , to the point that I'm taking 4 tryptophan pills throughout the day, and I'm down to only 30% of my effexor pill, with absolutely no withdrawal effects!

    helps to improve quality of sleep

    Posted by LoseBodyFatBuildMuscle on Apr 22, 2013

    Now at half the bottle. I experience a deeper state of sleep after taking 2 of these before bedtime. (I take more care not to take any caffeinelike products at late afternoons/evenings since I discovered this interrupts sleep many hours after coffee's.) Does not causes any suffiness as with sleeping prescriptions. Like the fast delivery and low prices with Iherb.

    Great for helping me fall asleep

    Posted by Reviewer1645968 on Nov 11, 2012

    I'm trying many supplements to help me sleep; so far L-tryptophan the most helpful for me; I use it with melatonin.

    Calming for dogs -------- good stress reliever

    Posted by coconut on Jun 25, 2012

    My dog is easily upset and scared of thunderstorms. I don't like medicating him so after some research I tried this. He is more calm and I feel better that this is more natural than the meds his vet gave him. I also have had relief from stressors such as work. I can take it at work and not have to worry about presciptions. It won't make you drowsy. Just less stress and better able to cope. Take on an empty stomach for best results!

    Love that it is an all natural product. Just be sure to do compatibility checks with any meds or other supplements that you already take, as you can overdo and suffer with seratonin syndrome, a very frightening and possible fatal syndrome. Be, especially, wary if you are taking SSRI antidepressants.

    A life saver!

    Posted by Reviewer2990647 on Apr 15, 2012

    I had been many different medications over the years for anxiety, bipolar & sleep disorders but always continued to have some symptoms with TONS of side effects. 3 yrs ago I tried Doctors Best L-tryptophan and it changed my life! I combine it with St. Johns Wort and get in my Omega 3s and a good multivitimin. The best part is, NO SIDE EFFECTS!!!! Doctors Best has the 'best' products on the market!
