Quality
this product is AMAZING-I have purchase different teas and sleep tablets to help me fall asleep and stay asleep well one night the family was over and because of the laughing and playing and recalling old memories I did not take anything and because it was late pass 10 pm I could not drink my tea so the only thing left was the Tryptophan and wow I slept all night and I did not get up until 7 and I felt so good that I was able to get on with my usual activity -I recommend these pills for a good night sleep with few pills

Great for Sleep, Unwinding
I was looking for something that would help calm my natural anxiety and help me relax before bed time. My doctor has recommended that I go to bed earlier, and it was a struggle at first to get myself to relax enough to be able to fall asleep early. L-Tryptophan is fabulous. I take one capsule to take the edge off earlier in the evening, and then one about a half hour or so before I want to actually go to sleep. It does its job! It does not, however, stop me from waking up in the middle of the night. I typically wake up anywhere from one to four or five times a night. Perhaps at a higher dosage it would, but I am nervous about taking too much and "snowing myself" for the following day. As far as I can tell it doesn't make me groggy at all in the morning which is great. I would recommend this product to anyone who is struggling with anxiety and/or needs help falling asleep. It is far safer than a prescription sleep medication. I have been on products like Ambien and trazodone in the past, and these had the effect of making me feel tired all day afterwards, as well as giving me unbelievable brain fog. Stick to natural solutions if you can! Other tips: use a red light in your environment before bed time; do deep breathing/meditation before bed; stop watching tv/computer about a half hour or earlier before bed etc. So many times we tell ourselves "oh there is no way that would work" or "I don't have time for that," but honestly, rest is so important - make time for yourself. Your body will thank you.

Life-Changing Supplement
I’ve been using NOW Foods L-Tryptophan 500 mg for a few months, and I am truly amazed by the difference it’s made in my daily life. I’ve struggled with anxiety and irritability symptoms for years, and this supplement has been a game-changer. Since I started taking it, I’ve noticed a significant reduction in anxiety and mood swings. I feel more relaxed, focused, and less easily frustrated throughout the day. What I love most is that it doesn’t cause any drowsiness or side effects – just a natural sense of calm and well-being. The capsules are easy to take, and the 120-count bottle lasts a long time, making it a great value. If you're dealing with similar symptoms, I highly recommend giving this a try – it’s been incredibly helpful for my mental health!

Tripping the "night" fantastic!
Okay, so, I waited 3 weeks before reviewing. I wanted to see if L-Trptophan (I will call it "T" from here on in since it's shorter) worked, or even helped or did anything remotely positive towards helping me sleep better. what has not worked for me (keep in mind they may work for you): Valerian - did nada for me 5 -HTP - nada as well Catnip - supposed to be a sleep enhancer believe it or not - nope Passionflower - nope Kirkland sleeping aids - helped a wee bit but not enough Tylenol PM - ha ha..not a bit Alcohol - I really struggled with not using this to help me sleep - there were times when I would use wine but it became such a habit plus it altered my personality - please just don't...trust me Marijuana - I smoked the indica kind - supposed to help you sleep - all it did is make me think for 3 hours that my bones were uneven (is there such a concept?) anyway, I am open to perhaps the oils, I live in Vegas so it's legal here Worked: Magnesium - helps keep me regular but I don't think it helps me sleep Meditation - Yes, if I do it - esp. right before bed - it helps quiet my mind - I am working on doing it more Melatonin - yes, I take 10 mg at night now that I am on "T" - it's supposed to help with "T" Quitting my job and going back to school for what I love - helped A LOT but I still struggle with anxiety when I wake up during the night Walking - or any kind of exercise that gets you to move Quitting cigs - yes, they bring you comfort but they are a stimulant and we all know are bad for you Eating cleaner - yes, ice cream is fun and so are burgers but it takes a lot to digest and that can keep you awake and or give you a restless sleep Ear plugs/eye mask - cool room - no animals while you sleep (except maybe your absolute best fur baby but if they wake you up often - they go to). Tradazone - wonderful for about 3 months, then at 200 MG - it stopped working. Finally, Seroquel - at a high dose it's an anti-pyschotic but at a low dose it's been prescribed by doctors to help others sleep. This stuff is strong - I do not recommend it unless your (like I was) quality of life is so bad because of lack of sleep - even then - talk with your doctor Back to my insomnia - what's criminal (or should be) is that I do not sleep DEEPLY enough, AND it takes me like 1-3 hours to fall asleep (this is WITH Seroquel). I have spent MANY nights crying - like close to hysterics because I struggled so much with it. Of course my sleep was worse when I had to get up early and coupled withwhen I hated my job. (quit if you can - seriously). So, I have been on "T" for 3 weeks now, I will say the first week, I did not know what I was doing, I was taking "T" 4 or 5 x a day WITH food, without food etc. I think I was thinking more is more...it's not. I finally got the "TAKE WITHOUT FOOD" part and it started to work! When I say work, this does not mean I do not still take the seroquel - because I do but I take the "T" on an empty stomach about 3 X a day (meaning 2 capsules each time) which amounts to 3000 MG. My sleep is not only deeper but I do not wake up as much (I would wake up about 6X at nite...to go to the bathroom or just honestly get up because I was wide awake and was tired of tossing and turning). I slept a little under 7 hours the other day and normally? I'd be feeling really sick - I feel like I have the flu or worse if I don't sleep enough - not this time. I was FINE - not only fine but instead of feeling crummier as the day went on? I actually felt better. I really hope this stuff is the real deal. I left off ONE star because I want to update this (can I make this any longer of a review?) because this is very important to me - and I know it probably is to you - sleep is SO dang important! Most Americans do not get enough of it. Here's hoping this review helped you and that Tryptophan will help you too.

カプセルを手に取った瞬間、そのサイズ感に小さな覚悟を決めた。水を多めに準備して挑む儀式が毎回発生し、まるで自分が修行僧になった気分だ。パッケージはシンプルで海外感が漂うが、開封時に『これが幸せホルモンの入り口?』と心でつぶやいた。飲み込む瞬間は静かな戦いで、舌と喉が協力しないと勝てない。結論として、カプセルはただのサプリなのに、毎回ちょっとしたイベントを演出してくれる存在だ。海外直送の雰囲気があり、棚に置くだけで気分が変わる。カプセルを見た瞬間に『今日も頑張ろう』と謎の決意が湧く。海外直送の雰囲気があり、棚に置くだけで気分が変わる。 良かった点/注意点:パッケージの清潔感と安心感/カプセルが大きめなので水は多めに準備、即効性を期待しないこと
