    Top quality Tryptophan

    Posted by Reviewer2193776 on Nov 24, 2007

    I just switched a week ago to this tryptophan from another brand...and I'm feeling better. That could be many factors (this isn't exactly a double-blind study) but I am convinced this is one of the better quality products out there. I will buy again.

    This stuff rocks!

    Posted by Reviewer2308213 on Jun 19, 2009

    I take two every night before I go to sleep. It helps me to sleep and feel relaxed the next day. It is the only natural product that consistently gives me that "feeling of well-being." I really like this and recommend it. It is so much less expensive here on iherb than at my local health food store. It has also helped with depression and anxiety.

    I bought this for my 19 year old daughter who suffers from anxiety, and does not want to be on meds, it does help her to sleep better at night.

    O produto é de excelente qualidade e preço. A entrega demora um pouco devido aos tramites no Brasil, mas chegou bem embalado.

    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!
