Life-Changing Supplement
Iโve been using NOW Foods L-Tryptophan 500 mg for a few months, and I am truly amazed by the difference itโs made in my daily life. Iโve struggled with anxiety and irritability symptoms for years, and this supplement has been a game-changer. Since I started taking it, Iโve 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 doesnโt cause any drowsiness or side effects โ 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 โ itโs been incredibly helpful for my mental health!

Awesome sleep aid
I recently added L-Tryptophan to my sleeping aid cocktail, and it's been amazing. The main benefit I've noticed since I started taking L-Tryptophan is when I wake up now (be it after 4, 6, or 8 hours of sleep) I feel instantly awake and ready to go. It's interesting to feel fully refreshed after 4hrs of sleep, something I haven't felt since I was younger. Although it may not last throughout the day, but I believe it's a good indication of how well this medication is working. The addition of L-Tryptophan also makes me more tired and helps me actually fall asleep moreso then any one thing I take. I've suffered from insomnia since I can remember, even if I want to sleep and am trying - my brain is simply too active to let me sleep at night. I took ambien for a short time and it was one of the worst medication experiences I've had. So have been experimenting with different combinations of OTC sleep aids the past couple years. My currently nightly ritual (unless I'm somehow tired already) is : 1-2x Nature's Bounty Melatonin, 3 mg, 240 Tablets 1x Doctor's Best Suntheanine L-Theanine (150mg) Vegetable Capsules, 90-Count 1x Now Foods L-tryptophan 1000mg, Tablets, 60-Count (or two of these) 1x Nature's Way Chamomile Flowers , 350 mg, 100 Capsules (sometimes) 1x NOW Foods - 5-HTP 200 mg - 120 - VegCap It may seem like a lot, but it beats ambien, or any other sleeping medication I've taken. I am generally a very light sleeper with lucid dreams, and this combination has not effected that any. It just simply calms my brain down enough to let me fall asleep. When I wake up I feel fully refreshed and ready to go, no groggy feeling you get with a lot of other sleep aids.

Wow! Game Changer.
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 theyโve 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 wouldnโt say these are wholly sleep inducing, but they do help me sleep, fall asleep faster, and feel well rested when I wake โ something Iโve never really experienced. They donโt 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 itโs not such a stark contrast anymore. Iโve suffered with depression, lethargy, and general malaise for most of my life. I wouldnโt 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 didnโt know it. Iโm mostly vegetarian, but even when I do eat meat, I donโt eat much; Iโve never eaten seafood and recently stopped eating eggs, so Iโm sure I wasnโt 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, Iโd certainly give these a shot. Maybe even try l-tyrosine in the day to see what works for you. I think itโs 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 youโre taking in from your meals.

Supposedly better than melatonin, at least for safety
I used to use melatonin for sleep for occasional use. Then I found out about this and it had a higher recommendation, mostly because it's safer, as melatonin has some serious downsides depending on how it's used or overused. I guess this does give me a calm, I have to do more testing, but for straight knocking me out for sleep, I don't think this does that. It's more of a slow acting substance. This is something I would take a couple times through the day and a couple hours before bedtime.

A magic pill?!
I am so happy I did research on natural anxiety remedies,found this, and kept an open mind and tried it. I used to take Hydroxizine almost daily for anxiety. Even though I wanted and theoretically "needed" to take it daily, I couldn't since it builds up a tolerance, it won't work as well if ingested too often, and I didn't want to be that person who is a slave to this big pharm system we have going on in America. After 2 weeks of taking this along with GABA I rarely take my Hydroxizine anymore (one every 3 weeks approximately, if I really think I'll need it for an important event). I am blown away at how well this helps me feel centered and calm. I used to get nervous when something as simple as my roommate coming home or going to the kitchen while I'm watching tv in the living room! Which sounds ludicrous to most normal people I'm sure, but I have intense anxiety and used to have trouble with seemingly small, insignificant social interactions. Now since taking this for a couple months along with GABA and my newly introduced theanine, I'm comfortable in my own skin. Now I can even drink coffee with caffeine in it which I could never do before because my hands would get shaky, I would get paranoid and nervous, even to the point where even if I drank just ONE cup of watered down coffee before work, I dreaded showing up and having to interact with customers and coworkers. Yesterday I drank a vlVenti Iced Mocha from Starbucks with an extra shot of espresso so I could stay awake during a 6 hour late night cross state lines drive (and the employee at the Starbucks said that it already has 3 shots in it) and I was not anxious at all! Even when I arrived to my destination I was calm, and used to be so caffeine sensitive I couldn't drink 1 cup of coffee! Anyways, this has helped me regain my life, confidence, and who I really am supposed to be without anxiety keeping me caged in. You should trust me and give it a shot. What do you have to lose? $12? Seems like it's worth a shot to me. I hope it helps you as well as it helped me... :)
