For Anxiety "After trying several SSRI drugs for my low to moderate anxiety and depression, I finally tried Tryptophan. I started with 250 mg, a very low dose. IMHO, I think that many people start most drugs and alternative 'remedies' at WAY too high a dosage, especially SSRIs, statins, and tranqs. I slept well the first night and woke feeling rested and without the 'cloud' of low-level anxiety and depression. I do NOT believe this was a 'placebo' effect. I increased to 500 mg and slept and felt even better! I will stay at this dosage. Those with much more serious anxiety/depression may do better on a higher dose, but I strongly recommend moving up incrementally. I am still looking into what would be the best schedule for this, daily an hour before bedtime, or every other day, but this, for me, is a BIG winner!"

For Insomnia "I am a survivor of brain cancer and now have a memory deficit as a result. My neurologist suggested I take 100 mg of L-Tryptophan daily to increase the production of serotonin. He felt this would assist with memory function. Long story short, two years later, I realize that I have benefited from the side effect of sleepiness. I take my 1000 mg before I go to bed and I sleep like a log."

"I suffered through a year of acute insomnia triggered by strange noises coming from my sinus, probably some kind of twisted blood vessel, although my ENT could never say for sure, and I didn't want a CT scan. My MD had me on Zopiclone, which is OK for the short term, but just garbage as far as long-term use: it interferes with REM sleep, develops resistance, and is hell to come off of with rebound insomnia and mood shifts, mostly dark. My MD was reluctant, but I talked him into letting me try tryptophan. Ahh, sleep! Quality sleep too. Natural sleep. No side effects except the occasional morning headache and grogginess that would soon disappear. No other side effects. No building up resistance over long-term use. To me, it's been a sanity saver."

For Insomnia "This seems to make me feel sleepy and sleep better than the meds that the doctors have tried. I also like that I don't wake up feeling dopey and have that 'hung over' feeling all day long that you get from some prescription meds."

For Insomnia "L-tryptophan feels like a bit of a lifesaver for me. Having endured insomnia for 7 years and tried so many various treatments - this natural amino acid has given me back my energy and ability to sleep 7-8 hours just like other people do! The extras are that my mood is stable during PMS and going through peri-menopause. I feel happier, more relaxed, and able to enjoy and appreciate my life so much more."

For Premenstrual Dysphoric Disorder "Nothing, and I mean nothing (and I have tried everything) has helped my PMDD like L-Tryptophan has. My symptoms are now negligible with just one 500 mg tablet plus a vitamin B supplement, once or at most twice a day."

For Anxiety "I had problems with sleep, anxiety, and some more things for a long time. I've tried melatonin, but it didn't help me. Then I've tried L-tryptophan, and I've noticed changes on the first night and so on. I'm using it for almost 3 months (not every day) before going to sleep, and I feel much better now. I got 700mg tablets, works really well with me. Be careful about interactions with other pills."

For Depression "I began taking tryptophan for low to moderate anxiety and depression after having several failures with SSRI drugs. Started with 250 mg, only two days... first day it made me feel much more relaxed... 2nd day it brought on anxiety attacks... I am still waiting for this stuff to get out of my system."

For Insomnia "Used this for insomnia. I got no worthwhile results on the first night taking half an hour before bed. The second night took one, gave me very gassy burps with a sort of grass-like aftertaste. The third night took about 3 hours before bed, this time, about half an hour after taking, I get another gassy burp, but this time I involuntarily spit out this green grass-looking stuff and just generally a very unpleasant taste in my mouth. Then, five minutes later, after a bit of water to get rid of the taste, the roof of my mouth has that nasty stinging sensation, like when a cold or flu bug is starting to kick in. Horrible sensation, yuck! Gonna chuck the rest of these in the bin!"

For Depression "I used this product, and it really killed me. It is extremely dangerous when combined with other medications and was banned for a reason. Now left with severe inflammation and nerve damage. Wish I'd researched further, not just product reviews, which are only positive. Please, please ask your doctor first or research. Wish I had...."

For Insomnia "L-Tryptophan has worked wonders for my insomnia, PMS, anxiety, and depression. No side effects, although the bottle says to take 3 capsules, I only take 1 at night and wake up feeling great."

For Insomnia "I tried it for two nights, an hour before sleep for maintenance insomnia. Both times it made my sleep worse and far more alert than usual, definitely didn’t work for me."
