I haven't tried this alone with no other sleep aids, so I do not know how much it is helping yet. I would try it again, though.

Thanks for your feedback!

i didn't feel much of an effect from these. i feel kinda jealous of people who write about walking into paradise garden after taking it or something. i also give one tablet to my boyfriend in the morning before work and i think there were some improvements in his mood since he was stressed at work.

Thanks for your feedback!

Good sleep and mood enhancement.

It is hard to tell with these suplements, but I think this works good for sleep and mood. I try not to abuse these too much...I take now and then. My gf is happy with these too.

Thanks for your feedback!

I love using Tryptophan. I was looking for something that would help me get a deeper more restful sleep at night after 5 years of sleep deprivation following the arrival of my 3 sons. I was having trouble going to sleep and waking easily through the night. I was feeling quite irritable, out of balance and I have anxiety with OCD traits. My Dr Advised that it may be depression and to journal my symptoms and consider future use of medication. I didn't want to turn to medication right away. I found out about Tryptophan and I liked the idea of how it helps boost the bodies ability to produce melatonin and serotonin in its natural form. So I started on 500mg at bedtime with 500mg of GABA. On the plus side i woke feeling great, well rested and clear thinking, more energy, positivity and no irritability. I actually felt like I really slept and I know I did because I was dreaming big time, I usually don't dream or rarely remember them. On the minus side by noon i was starting to slow down, feeling an afternoon slump and I had bad dreams with one night waking with heart palpitations. I was experiencing horrible nightmares for 3 nights straight so I decided to stop for a day. The irritability returned following a poor night of sleep. I decided to take 250 mg with 500 mg of GABA at bedtime and that seemed to work for me. I'm about 150 lbs and 5'4" so maybe I don't need a high dose. I feel great on it and couldn't imagine going a night without it.

Thanks for your feedback!

Brilliant Product

This product has a terrifically positive effect on my mental well-being. I recommend it to enhance the effect of SSRIs or on its own for helping bring about a feeling of happiness & well-being.

Thanks for your feedback!

helps with sleep and mood

I usually take melatonin for sleep issues but found especially in the winter that I am very glum and pessimistic probably due to reduced sun exposure. Tryptophan is great at converting to melatonin or seratonin depending on the body's need. I have been taking this for about two weeks and sleep is great and mood is much much better overall. I take one at night. I found that it takes about 2 hours before I feel ready to sleep. No grogginess. Could continue to stay awake if I decided to. I like that it doesn't feel like a drug effect. Very mild but effective.

Thanks for your feedback!
