NOW Foods GABA, L-Tryptophan, 5-HTP, Taurine, I take all of these daily now. Enhances my overall mood, attitude, outlook on life, and energy levels. I simply feel better taking these supplements. Helps me through the depressing winter months.For myself, I find that these are best taken on an empty stomach with a cup of coffee in the morning, and then I won't eat for an hour afterwards. Then I might take again at around 6 PM, as I typically don't eat dinner until 8 PM.Good stuff, good quality. Repeat customer.

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!

Know your amino acid! L-Tryptophan is a precursor that your body uses to produce serotonin, a neurotransmitter that plays a key role in the central nervous system and in the digestive system.I am sure these are quality ingredients from a good company. The product was fine. However, how your body responds can be very unpleasant and possibly even dangerous. Please read about Serotonin Syndrome before taking. If you are taking an anti-depressant or niacin (which goes by two other names for fun), taking L-Tryptophan can cause serious problems in the central nervous system.Luckily I had no problems here. However, I was unaware of the extent of the role serotonin plays in the digestive system. I took precisely two of these pills — with breakfast on consecutive days. This made my intestines very, very angry. After two pills, I spent two weeks always knowing the distance to the nearest toilet. No matter the time of day, if food went in — even a small yogurt or two bites of a granola bar — a 10-minute (give or take) timer began. I didn’t feel comfortable leaving the house unless it has been at least 3 hours since I consumed anything but water. Thank goodness the park near my house has restrooms, or I would have had a new most embarrassing adult moment.I don’t fault the product itself. Indeed, high quality ingredients likely enhanced the effects.

Also supposed to help with mood, as it is a precursor to serotonin.

I had no idea I might be low on some amino acids, nor that supplementing could be so helpful. My brother recommended them for help sleeping and mood support, and they’ve delivered! Both my mood and sleep have improved so much. I feel balanced in a way I maybe never have. I decided to take these in the evening and use l-tyrosine in the daytime. The combination has been fabulous! I take about 500ml of each. Sometimes I take 1000 mg of the l-tryptophan and gosh I sleep soooo well. I wouldn’t say these are wholly sleep inducing, but they do help me sleep, fall asleep faster, and feel well rested when I wake — something I’ve never really experienced. They don’t make me groggy, and I wake up so much less cranky! For the first week I could literally feel the relaxation in my whole being. That has worn off a bit, but I think I just got used to feeling good and relaxed so it’s not such a stark contrast anymore.I’ve suffered with depression, lethargy, and general malaise for most of my life. I wouldn’t say these are an antidepressant, per se, but adding them with the l-tyrosine has improved my mood a TON! I think I was very low on these amino acids and just didn’t know it. I’m mostly vegetarian, but even when I do eat meat, I don’t eat much; I’ve never eaten seafood and recently stopped eating eggs, so I’m sure I wasn’t getting enough amino acids. Plus, food is just low nutrition these days and we all should think about ensuring we get what our body needs to maintain a good state of mind and energy.I genuinely believe these could help others. If you struggle with sleep and low mood, I’d certainly give these a shot. Maybe even try l-tyrosine in the day to see what works for you. I think it’s important to take them on an empty stomach so make sure to do that or else the effects may not be very apparent, as they compete with what you’re taking in from your meals.

Great value, mood improvement, and effective.

I've tried this a few times, with breaks in between, hoping to get a better result each time. But it's just not working for me. Rather than calm anxiety, it makes me more jittery and nervous the next day -- and caused heart palpitations. Oddly, it kept me awake and didn't help me sleep.I suspect this is something that works if your body actually needs it, or works best in exactly the right doses. I followed the directions on the bottle, and even cut back the dose a couple times to see if that would help. But it didn't. I am usually pleased with NOW products, but this one isn't for me.
